This document summarizes a study that investigated the impact of government agricultural expenditure on economic growth in Zimbabwe from 1980 to 2009. The study employed a log linear regression model with gross domestic product as the dependent variable and factors such as government expenditure on agriculture, investment, and consumption as explanatory variables. The regression analysis found that increased spending on agricultural research and development can improve economic growth. However, insufficient government expenditure on agricultural extension and credit assistance adversely affected economic growth in Zimbabwe. The results provide evidence that agriculture is an engine of economic growth in the country.

Government Expenditure and Economic Growth Nexus: Empirical Evidence from Nig...iosrjce
This study has examined the impact of public expenditure on economic growth in Nigeria using time
series data for the period 1970-2012. Secondary data were sourced from the CBN, NBS, journals, text books
etc. The adopted model was fitted with three variables: real GDP, capital and recurrent expenditure. The tools
of analysis were the ADF unit root test and ordinary least square multiple regression accompanied by pairwise
Granger causality test. The major objective of this study is to analyse the impact as well as direction of
causality between the fiscal variables and economic growth. All the variables included in the model are
stationary at level. Empirical findings from the study show that there is positive and insignificant relationship
between capital expenditure and economic growth while recurrent expenditure had a significant positive impact
on economic growth. Also, Granger causality test demonstrates a unidirectional causality running from the
fiscal variables to economic growth in validation of the Keynesian theory. Consequently, the study
recommended more allocation of resources for recurrent purposes as well; government should establish the
body that will monitor contract awarding process of capital projects closely, to guard against over estimation of
project cost and stealing of public funds.
Abstract: The paper examines the impact of public sectoral expenditure on economic growth in Nigeria for the period 1981-2013. It was observed that the growth of government expenditure has not fully felt by the economy. The econometric methodology employed is the ARDL model and results show that while the impact of government expenditure on administration and debt servicing were positive on economic growth in the long and short run, expenditure on economic and social sectors has negative impact. We argue that this may not be unconnected with the high level of corruption prevalent in the public sector where funds that are meant for provision or maintenance of social-economic activities like agriculture, roads, transportations, schools and hospitals are diverted for personal use. The CUSUM and CUSUMSQ test show the model is stable as neither of them cross the 5% boundary. The paper recommended that government should increase expenditure to the social and economic sectors while debts or debt servicing should be reduced. Also, corruption so prevalent in the public sector must be minimized if cannot be eradicated.
Analysis of Public Investment Expenditure on Economic Growth in WAEMU Countriesinventionjournals
Public investment expenditure plays an important role in the economy to produce goods and services needed for economic development. This study analyzes the influence of public investment spending on the economic growth of the WAEMU zone. The study considers a linear approach through individual fixed effects models with Beck-Katz and Driscoll-Kraay corrections, the spatial autocorrelation model (SAC) and the longterm model (DOLS). The empirical results of the study using panel data covering the period 1990-2015 indicate that public investment spending can promote economic growth in WAEMU countries when they are allocated in decreasing order to Education, health, public investment in basic road infrastructure and agriculture. However, they are also likely to slow it down when they focus on military spending, even though their primary objective is to ensure security for economic development. Finally, the study recommends that policy makers in WAEMU countries refocus their public expenditure policies in key sectors of development, notably human capital, in order to ensure a multiplier effect of public spending on economic growth and strengthen institutions Democracy to ensure their independence through their interdependence.
Using time series data, this study investigated the effect of aggregated and disaggregated public spending on economic growth in Nigeria during the period 1980 – 2015. Time series data such as aggregated expenditure proxy by total federal government expenditure (TFGE), disaggregated expenditure proxy by recurrent expenditure (REXP) and capital expenditure (CEXP,) and economic growth proxy by GDP were obtained from central bank of Nigeria (CBN) statistical bulletin. Error Correction Model (ECM) was used to estimate the model. The result of the finding revealed that the total federal government expenditure (TFGE) and capital expenditure (CEXP) exerts positive and significant influences on GDP while recurrent expenditure (REXP) has a positive and insignificant influence on GDP. This implies that the higher the public spending, the higher the GDP. The researchers therefore, recommend that for sustainable Economic Growth (GDP), federal government should increase capital expenditure by allocating more funds to the productive sector of the economy. More so, the positive contributions of public spending to economic growth necessitate the continued use of fiscal policy instruments to pursue macroeconomic objectives in Nigeria.
The spending allocation pattern of national governments varies depending on public policy for
desired effects but the outcome is rather controversial according to existing literature. This research aims to
explore the relationship between government expenditure, economic development and economic growth in
Brazil from 1994 to 2017. The Human Development Indicator (HDI) index is a representative measure of
economic development and is comprised of three dimensions:
The main focus of this study is to investigate the impact of expansion in economic growth on
government expenditure in Nigeria covering the periods 1970 to 2012. Gross Domestic Product (GDP) was
used as a proxy for economic growth, and the GDP time series was decomposed using the partial sum approach
in order to achieve asymmetry in the variable. The asymmetric ARDL estimation technique was appropriately
employed in this study. The findings of this study revealed that expansion in economic growth has significant
impact on government expenditure in Nigeria. The study further provided evidence of long-run causality from
boom/expansion in economic growth to government expenditure in Nigeria but could not support any evidence
of short-run causality. The researcher recommended among others, that Governments in Nigeria should give
more impetus to policies that will guarantee sustainable economic growth.

Effect of budget deficits on economic growthNigus Temare
The main objective of this study was to investigate the effect of budget deficit on economic growth in Ethiopia. For this purpose, the study used time series secondary data, and the data was extracted from the World Bank development indicators, Ministry of Finance, and National Planning and Development Commission of Ethiopia. The data covered a period running from 1994 to 2020.The study employed the Autoregressive Distributed Lag (ARDL) co-integration technique to determine the long and short-run relationship between budget deficit and economic growth. The findings resulted from modeling and analysis of the study showed that there exists a negative relationship between budget deficit and economic growth in Ethiopia and these results are consistent with the neoclassical economist schools of thought. Besides, the inflation rate is affecting the economic growth negatively and significantly whereas, government expenditure and trade openness affect the economy positively and statistically significant in the long run. On the other hand, the analysis in the short-run revealed that the budget deficit is positive but statistically insignificant. This indicates that budget deficit changes have no immediate effect on economic growth. The study suggested some policies which are important for the government of Ethiopia to avoid certain levels of the budget deficit to achieve the desired level of growth.
11.does the composition of public expenditure matter toAlexander Decker
The document examines the impact of public spending on various sectors on economic growth in Kenya from 1972 to 2008. It finds that:
1) Spending on education had a highly significant positive impact on economic growth, while spending on economic affairs and transport/communication also had a positive impact, though weaker.
2) Spending on agriculture had a significant negative impact on economic growth.
3) Spending on health and defense did not have a significant impact on economic growth.
The findings did not fully conform to the authors' prior expectations about the relationship between public spending and economic growth. The document reviews other literature that has found mixed results on this relationship.

The document reviews theories of public expenditure and public revenue. It discusses Wagner's law which states that government expenditure rises with economic development. Musgrave expanded on this, noting expenditure increases to develop infrastructure early on but may decrease later. Peacock and Wiseman proposed public spending increases in "jerks" due to disturbances. The document also examines theories of public revenue sources, including Dalton's classification of taxes versus prices and Taylor's categories of grants, administrative revenues, commercial revenues, and taxes.
This document discusses the relationship between economic growth and public expenditure in India based on Wagner's Law. It introduces the six versions of Wagner's Law proposed by different economists from 1961 to 1980. The document then reviews several previous studies that have examined the validity of Wagner's Law in India and other countries. The focus of the current study is described as examining the relationship between public expenditure and economic growth in India using the six versions of Wagner's Law. The study uses annual time series data from 1970-71 to 2011-12 and tools like unit root tests, cointegration analysis, vector error correction models, and Granger causality tests to analyze the data and test the hypotheses.
The Bangladeshi economy has undergone significant structural changes over the past four decades. The share of agriculture in GDP has declined from over 60% to less than 20%, while industry and services have increased substantially. The manufacturing sector has become increasingly oriented towards ready-made garments, driven by the expansion of the RMG industry. The unemployment rate is low but many workers suffer from underemployment and informal employment. Structural change models focus on how economies transform from agriculture to more modern manufacturing and services. Lewis's model and Chenery's patterns of development analysis are two influential structural change models.
The document discusses the potential for rural economies to contribute more to global economic growth by 2030. It presents the results of economic modeling under three scenarios: 1) a baseline extrapolation of current trends, 2) a scenario where rural growth is "unleashed" through policy reforms in response to a downturn, and 3) a scenario of gradual rural decline. The modeling estimates that "unleashing" rural growth could boost annual rural output by $2 trillion globally by 2030 compared to the baseline. Six countries - Angola, Argentina, China, France, India, and Nigeria - are profiled to illustrate challenges to and opportunities for rural development.
An Analysis of the Relationship between Fiscal Deficits and Selected Macroeco...IOSR Journals
This study investigates the relationship that exists between the Government Deficit Spending and selected macroeconomic variables such as Gross Domestic Product (GDP), Exchange Rate, Inflation, Money Supply and Lending Interest Rate. The period covered is 1970 (when the civil war ended) and 2011. Ordinary Least Squares (OLS) technique was adopted to analyze the relationships. The study concludes that Government Deficit Spending (GDS) has positive significant relationship with GDP. Government Deficit Spending also has positive significant relationship with Exchange Rate, Inflation, and Money Supply. Government Deficit has negative significant relationship with Lending Interest Rate and most likely crowd-out the private sector by raising the cost of funds. Deficit spending has been known to have adverse effects on the economy and government is advised to curtail excessive deficit spending. It is recommended that further research is done to establish other variables that are affected by government deficit spending.

This document provides an introduction to macroeconomics and key concepts like GDP (gross domestic product) used to measure economic growth. It defines macroeconomics as dealing with the performance and decision-making of an entire economy rather than individual markets. GDP is introduced as the market value of all final goods and services produced within a country in a year, though it has limitations in accuracy since it does not include all economic activity and illegal/home production. Other measures like per capita GDP, purchasing power parity, and real growth rates are also discussed to provide additional ways to analyze and compare economic growth between countries.
This document analyzes the impact of revenue allocation formulas on economic growth in Nigeria. It finds that past revenue allocation formulas have affected Nigeria's economic growth and development path. There is a need to address problems with more efficient revenue allocation to reduce wastage and mismanagement of funds. The revenue allocation formula influences capital formation, employment, and economic growth. Changes to Nigeria's internal structure through increased state creation have distorted the revenue allocation formula and weakened federalism. The objectives of the study are to examine how past revenue allocation formulas have impacted economic growth in Nigeria and propose solutions to problems in the formula to support rapid economic growth.

The nexus between budget deficit and inflation in the nigerianAlexander Decker
This research paper examines the relationship between budget deficits and inflation in Nigeria from 1980 to 2009. It uses time series data and the vector error correction mechanism to analyze the correlation between the two macroeconomic variables. The results show there is a significant causal relationship from budget deficits to inflation, but not from inflation to budget deficits, indicating a unidirectional causality. This means budget deficits directly and indirectly affect inflation through increases in the money supply in the Nigerian economy. The paper recommends adequate monetary policy to balance the role of money supply in influencing both budget deficits and inflation, given the unidirectional relationship found between the two variables.

The Calculation of Optimal Osmotic Dehydration Process Parameters for Mushroo...Agriculture Journal IJOEAR
Abstract— The Firefly Algorithm (FA) is employed to determine the optimal parameter settings in a case study of the osmotic dehydration process of mushrooms. In the case, the functional form of the dehydration model is established through a response surface technique and the resulting mathematical programming is formulated as a non-linear goal programming model. For optimization purposes, a computationally efficient, FA-driven method is used and the resulting optimal process parameters are shown to be superior to those from previous approaches.

This document summarizes a study that investigated the impact of macroeconomic variables (exchange rate, interest rate, government capital expenditure, government recurrent expenditure) on non-oil exports, the agricultural sector, manufacturing sector, and GDP in Nigeria from 1986-2010. The study used ordinary least squares regression and cointegration analysis. The results showed that exchange rate, government capital expenditure, and government recurrent expenditure were positively related to non-oil exports, agriculture, manufacturing, and GDP, while interest rate was negatively related. Based on these findings, the study recommends increasing investment in non-oil exports, agriculture, and manufacturing, as well as decreasing interest rates and increasing government expenditures.

This document analyzes the effects of capital flight on economic growth in Nigeria from 1980 to 2011. It finds that large capital outflows from Nigeria are due to political instability, high fiscal deficits, high interest rates, and high external debt servicing costs. It recommends policies to alleviate capital flight such as good governance, fiscal discipline, and enacting laws to encourage repatriation of illegally moved funds for investment in Nigeria's real economy.

The Calculation of Optimal Osmotic Dehydration Process Parameters for Mushroo...Agriculture Journal IJOEAR
Abstract— The Firefly Algorithm (FA) is employed to determine the optimal parameter settings in a case study of the osmotic dehydration process of mushrooms. In the case, the functional form of the dehydration model is established through a response surface technique and the resulting mathematical programming is formulated as a non-linear goal programming model. For optimization purposes, a computationally efficient, FA-driven method is used and the resulting optimal process parameters are shown to be superior to those from previous approaches.

This document summarizes a study that investigated the impact of macroeconomic variables (exchange rate, interest rate, government capital expenditure, government recurrent expenditure) on non-oil exports, the agricultural sector, manufacturing sector, and GDP in Nigeria from 1986-2010. The study used ordinary least squares regression and cointegration analysis. The results showed that exchange rate, government capital expenditure, and government recurrent expenditure were positively related to non-oil exports, agriculture, manufacturing, and GDP, while interest rate was negatively related. Based on these findings, the study recommends increasing investment in non-oil exports, agriculture, and manufacturing, as well as decreasing interest rates and increasing government expenditures.

This document analyzes the effects of capital flight on economic growth in Nigeria from 1980 to 2011. It finds that large capital outflows from Nigeria are due to political instability, high fiscal deficits, high interest rates, and high external debt servicing costs. It recommends policies to alleviate capital flight such as good governance, fiscal discipline, and enacting laws to encourage repatriation of illegally moved funds for investment in Nigeria's real economy.
Agricultural Export, Oil Export and Economic Growth in Nigeria: Multivariate ...Agriculture Journal IJOEAR
Abstract—Sustaining of nation’s economic growth for better footing and outlook is very crucial for the globe of recent, most especially for developing countries like Nigeria. The country as a vivid example of a developing nation is oil based economy, which adopts export promotion policy as the essentialtactic for growth. Yet the nation has not maximized her abundance of resources to aids growth, despite notable economic growth being experienced. In this view, there is an attempt to examine the relationship among agricultural export, oil export and output growth in Nigeria. The causal relationship among the variables was investigated by using times series data for the period between 1981 and 2014. All the macroeconomic variables were found to be stationary. The study revealed that there is significant relationship between economic growth and the agricultural export and oil export. Based on the findings, government of the country is being advised to initiate new and re-defined old policies that will diversify the export base. Likewise, policies that will improveand aid the nation’s domestic production is being encouraged, since long run relationship has been established among the macroeconomic variables.

This document summarizes a study that investigated the effects of foreign direct investment (FDI) on food security in Ghana. The study found that daily energy and protein consumption, which are indicators of food security, were negatively related to agricultural FDI in both the short and long run. This suggests that agricultural FDI has had a detrimental impact on food security in Ghana. However, FDI can also potentially promote economic growth, job creation, and technology transfer in host countries. The document reviews both the potential positive and negative effects of FDI on development and food security.
Determinants of Income Inequality Among Cooperative Farmers in Anambra Stateijtsrd
This study examines determinants of income inequality among cooperative farmers in Anambra State. The study, modeled variables like farmers efficiency, technology, market proximity, credit obtained, farm size, soil fertility, crop type, input supply and agric extension services using descriptive and inferential statistics. The population of this study was made up of 298 members of selected cooperative societies in Anambra State and a sample of 171 was determined for the study using Taro Yamane formula. A structured questionnaire was administered to 171 respondents but only 115 responded to the questionnaire. The data collected using the questionnaires were analyzed using descriptive and inferential statistics. Findings revealed that apart from market proximity which was not significant, all other factors farmers' efficiency, technology, credit obtained, farm size, soil fertility, crop type, input supply and agric extension services contributed significantly to the farmers' income. This study therefore recommends that The government should carry out a public enlightenment campaign on the potentials of agricultural cooperatives as sustainable approach for reducing income inequality through synergy and emphasis should be placed more on cooperative education as requirement for growth and development since most of the people in the target areas has low educational background. The agricultural cooperative subsector should be adequately financed to help improve the farmers' income and also reduce income inequality. Agricultural technology transfer through extension services should be encouraged to help create awareness and increase adoption of better ways farming so as to increase the farmers' income and reduce income inequality among others.

This document provides an abstract and introduction for a study on the impact of incentives for indigenous farmers (A1 and A2) on maize production in Macheke, Mashonaland East Province, Zimbabwe. The study was motivated by a decline in maize deliveries to the Grain Marketing Board in Macheke despite an increase in the number of farmers. The objectives are to understand why production has dropped and to identify incentives to boost production. The introduction provides background on maize production in Zimbabwe and Mashonaland East Province. It reviews literature on Zimbabwe's "green revolutions" in maize and the current food security challenges. The research design utilizes a mixed methods approach through questionnaires, interviews and review of production and import
This research work examined the impact of Agriculture output on Economic Growth in Nigeria, with the objective of determining the relationship between the Agricultural sector and the Economic Growth rates in Nigeria. Thus, the research was aimed at examining the contributions of agriculture (value added) to the growth of the national economy, investigating government expenditure on agriculture in Nigeria, and determining the contributions of crop production from agriculture on the Nigerian economy. Data were collected from the World Bank Data base and CBN statistical bulletin. Co-Integration and Vector Error correction model techniques were employed as well as the Granger Causality test to determine the causality relationship between Agriculture and Economic Growth. As a result of the data collected, analyzed and interpreted, the research found that Agriculture has positive and long run impact on Economic Growth in Nigeria. The paper recommends amongst many other things that the Government of Nigeria should put in more efforts to diversify the Nigerian economy as the Nigerian agricultural sector currently suffers a lot of marginalization which has not enabled it to contribute more significantly as it should.
Performance Implication of Agricultural Transformation Agenda Support Program...ijtsrd
In a bid to revitalize the ailing agricultural sector in Nigeria, several programmes have been introduced by the government, one of such programmes is Agricultural Transformation Agenda Support Program Phase 1 Atasp 1 . Hence, this study was necessitated to look at the performance implication of the programme on participant farmers in Southeast Nigeria. The study specifically determined the effect of ATASP 1 interventions on the farm income of participants and ascertained the effect of ATASP 1 intervention on the farm profit of participants. A survey research design was adopted for the study. A total of 8,585 Rice 3248 and Cassava 5337 farmers are participating in the programme from Anambra and Enugu constituted the population for the study. A multi stage sampling technique was employed by the researcher. Taro Yamane sample size determination formula was further used to derive the sample size 730 of the study. R. Kumaison formula was adopted to allocate sample stratum for the study. Primary and secondary data were collected and used in the study. A combination of descriptive, regression and inferential statistics were utilized in data analysis. Results revealed that Pseudo R2 was 0.435 which implies that 43.5 variation in farmer's income was explained by the joint action of the programme interventions and that the Pseudo R2 was 0.300 which implies that the programme interventions explained 30.0 variation in the profit of farmers. Hence, it was concluded that ATASP 1 is a signifant and right step in the right direction to regalvanize the agricultural sector and give it the pride of place it desearves. Among others, the study recommended that there is a need for the programme to increase its efforts on financial market development intervention and that the programme implementers and policymakers are encouraged to increase their intervention in rural areas.

Impact of government school to-land agricultural project on rural development...Alexander Decker
This document summarizes a journal article that assesses the impact of a Nigerian government program called the school-to-land agricultural project on rural development in Rivers State. The program aims to promote rural employment, livestock and food crop production, and rural income generation. Survey results from 300 farmer participants and community members reveal that the program has contributed to rural development by increasing livestock and food production. However, the adoption of modern farming techniques and constant review of agricultural policies is recommended to avoid duplication of projects.
Mainstreaming sustainability in the Nigerian agricultural transformation agendaPremier Publishers
The document discusses issues around sustainability in Nigeria's Agricultural Transformation Agenda (ATA) program. It notes that while the ATA aims to modernize Nigerian agriculture, its heavy reliance on chemical fertilizers and ambiguous stance on GMOs could negatively impact future generations. Specifically, the program's fertilizer policy focuses on chemicals over organic alternatives, and does not take a clear position on GMOs, which have been linked to health, environmental and economic risks. The document concludes that while the ATA aims to empower farmers, its approach may actually benefit others at farmers' expense if sociological factors and sustainability are not properly incorporated.

The main objective of this study is to empirically examine the link between agricultural production and economic growth in Cote d’Ivoire based on poverty alleviation. The results demonstrate that government investment in agricultural sector play a significant and important role in the economic development both in short and long term, hence promoting living standard in Cote d’Ivoire. The paper also reveals that socio-economic and natural factors influence national agriculture production level in long run. As recommendation the study suggests that government and the private sector must combine their investment efforts on agricultural product transformation in order to boost national gross production by the sector mechanization. This reform could help to avoid agricultural sector dependency to natural phenomena like rain and drought.
Botswana Public Sector: Growth, Trends, Prospectseightbloxx
Botswana has experienced strong economic growth since independence in 1966, transforming from one of the poorest countries to an upper middle income country due to stable politics, prudent economic management, and effective use of natural resources like diamonds. GDP per capita grew from $70 at independence to $6,500 in just three decades. The economy has been driven by mining, which contributes significantly to GDP, exports, and government revenues. Public sector employment is also large, with the government contributing 40% of jobs. Key challenges include high unemployment around 20% in the 1990s and maintaining spending discipline given heavy reliance on mining revenues.
1) Agriculture is an important sector for the Indian economy, contributing approximately 17.2% to national GDP and employing 58% of the population. However, agricultural growth has often fallen short of targets.
2) The paper analyzes issues in agricultural financing in India, finding that credit delivery to the agriculture sector remains inadequate. Commercial banks remain hesitant to lend to small and marginal farmers.
3) An efficient agro-infrastructure can optimize resource use, increase farm incomes, widen markets, and create employment. Agriculture is financed through commercial banks, regional rural banks, and cooperatives.
Agriculture has been the major source of livelihood in Nigeria, primarily because the environment is favorable for Agricultural practice. On the basis of climate, topography and vegetation the country is divided into five agricultural zones, namely Dry sub humid, Sub-humid, very humid and swamp/flood. Subsistence agriculture formed the major system of farming in the olden days which provide food crops for human consumption, while surplus are transported to the local markets for sale. Subsistence agriculture also forms the basis upon which all other system of farming are built. Hence, this paper examines the problems and prospects of subsistence agriculture in Ibarapa East local Government Area of Oyo State. Ten farming centres were used as samples in the area. Questionnaires were used to collect relevant data. Percentage and T-test distribution techniques were used to analyze the data. The findings show that there is low agricultural production in the study area as a result of problems such as shortage of fund, land tenure system, inadequate transportation system among others.

Abstract:
A vibrant and an efficient agricultural sector would enable a country to feed its growing population, generate
employment, earn foreign exchange and provide raw materials for industries. The agricultural sector has a
multiplier effect on any nation's socio conomic and industrial fabric because of the multifunctional nature of
socio-economic
agriculture. The main objective of this study was to investigate how government expenditure on agriculture has
affected economic growth in Zimbabwe from 1980 1980-2009. The Log linear growth regression model was
employed where gross domestic gross was the dependant variable and the explanatory variables are the factors
which affect it which include government agricultural expenditure. The expenditures of government on
agriculture were divided into three functions namely extension, credit assistance and research and development.
The regression analyses were performed using Econometric

was carried out on time series data for the period 1980 to 2009. The data was tested for stationarity and for
autocorrelation. Problems of non stationarity of data were corrected by integrating the trending series. Results
from the empirical analysis provide strong evidence indicating that agriculture is an engine of economic growth.
The results from this study suggest that spending more on agricultural research and development can improve
economic growth and ultimately reduce poverty. However, it can also be concluded that insufficient government

BACKGROUND
In Zimbabwe, agriculture has been the mainstay of the national economy accounting for about 15 to 20 percent of
GDP but with a majority of the country’s population engaged in this sector (WFP, 2009). It generates a large
proportion of foreign exchange earnings, although the share of agricultural exports in the country’s total exports
has declined from 39 percent in 2001 to 14 percent in 2006 (WFP, 2009). According to Muchapondwa (2009), the
agricultural sector is still of great importance to Zimbabwe and any hopes of reviving the economy will necessarily
ector
have to include strategies focused on the agricultural sector.
Rukuni, Eicher & Blackie (2006) also reiterated that Zimbabwe has been dominated by agricul
agriculture although
it contributed only 15-20% to Gross National Product in most years. It also provides an income to over 75% of
20%
the population and in most years 95% of all food and beverages have been produced locally. Agriculture also
accounted for 30% of formal employment and more than 40% of total national exports (Rukuni, Eicher &
mal
Blackie, 2006).
The economy of Zimbabwe is relatively diversified but dependent mainly on agriculture. The agricultural
sector, as is often the case with less developed countries (LDCs), plays a key role in Zimbabwe's development
strategies. In prosperous agricultural years, tobacco and cotton exports account for 25% of total exports while the
sector as a whole can account for 45% of all exports (FAO, 2001). However, the agricultur sector only
agricultural
accounted for 12% of all exports by 2008 (WFP, 2009).
According to literature, the high pay off input model (Eicher and Staatz, 1984) envisaged that more inputs
pay-off
will be accompanied by higher output; that is higher investment in agriculture will result in higher contribution of
will
the agricultural sector to economic growth. This was not the case in Zimbabwe after 1985 when more funds were
channelled towards small holder farmers through Agricultural Finance Corporation, (AFC), a parastatal lending
institution (credit assistance).

Zimbabwe`s agricultural sector in 1999 contributed 27.5% of GDP and this has been declining since 2000 (FAO,
2006), and by 2008 it accounted for 15 20% of GDP (WFP, 2009). Various other agricultural performance
15-20%
indicators provide further evidence of the relative deterioration of the agricultural sector since then. For instance,
the total agricultural production per capita and the food production per capita index have been falling,
particularly since 2000. This partly explains the rampant food shortages that Zimbabwe has witnessed, with
explains
consequent increases in domestic food prices and the dramatic increases in agricultural imports that have been
observed since 2000. However according to Garcia (2007), the government of Zimbabwe has had extraordinarily
Zimbabwe
high expenditure relative to GDP and most of the funds were channelled towards agriculture to support Farm
Mechanisation Programme in 2007. This study seeks to investigate how variations in these expenditures on
agriculture have affected economic growth in Zimbabwe since 1980.
The study was carried out in Zimbabwe which is a land locked country in Southern Africa. The country has a
total land area of 39, 6 million hectares. Thirty three million hectares are reserved for agriculture while the rest is

reserved for national parks, forests and urban settlements (Manzungu, 1999).
The land in Zimbabwe is divided into five natural regions on the basis of soil type and climatic factors (refer
to Figure 1). The bulk of Mashonaland (West, East and Central), Midlands and Manicaland Province are under

Agriculture in Zimbabwe
Agriculture in Zimbabwe (1980-2000): After independence, more priority was given to agriculture as a means
2000):
to achieve economic development (Manzungu, 1999). Moreover these priorities in agricultural finance were
changed to include the small-scale farmers. The growth with equity programme (198 -1990) was designed to
scale (1980-
redress the colonial legacy in favour of communal farmers. This is because of the two main features of
agriculture at independence in 1980 which were the duality of agriculture and the high degree of government
intervention in the sector intended to stimulate production.
ector
With the advent of Economic Structural Adjustment Programme (ESAP) in 1990, trade barriers, price
controls, subsidies and production quotas were removed (Manzungu, 1999). In the mid-1990s, the government
mid-
anticipated ESAP would transform the nation's small scale, subsistence agriculture into widespread commercial
small-scale,
farming and generate annual agricultural growth greater than the rate of population growth. Its aim was to
develop the necessary physical and social infrastructure in rural areas, but little of this has happened. With
infrastructure
budget allocations for rural infrastructure and other capital projects down, farmers lacked the roads and adequate
transport systems, as well as the processing, storage and distribution systems, they require in order to be
competitive (Saprin, 1999).
Agriculture in Zimbabwe (2000-2009): According to Zumbika (2000), the formation of Agribank in January
2009):
2000 negatively affected the smallholder farmers. The government created the Agricultural Develop Development
Assurance Fund (ADAF) as a fund specifically meant for extending loans to smallholder farmers by so doing
filling the gap which was left by Agricultural Finance Corporation ( (AFC).
More support was also made available to farmers through The Mechanisation Programme which was
financed by the Reserve Bank of Zimbabwe. It has benefited farmers in both the commercial and communal
sectors. The Government, through the RBZ, which took into cognisance the high cost of acquiring machinery on
cognisance
individual farmer basis, took it upon itself to revolutionalise farming by providing the machinery to farmers. The
equipment procured includes combine harvesters, tractors, harrows, ploughs, planters and ot other animal drawn
farm implements. As at 4 January 2008, a total of 646 tractors and 28 combine harvesters had been delivered to
beneficiaries (RBZ, 2008).
In a bid to reinforce existing support measures in the agricultural sector, the bank enhanced its fu funding
activities under the Agricultural Sector Productivity Enhancement Facility (ASPEF). This was geared at ensuring a
full support system of the farm mechanisation programme. A cumulative amount of $62.215 trillion had been
disbursed to 25 477 applicants by 4 January 2008 (RBZ, 2008).
The Fast Track Land Reform Programme (FTLRP) was officially launched in July 2000 culminating in
extensive land transfers to local black farmers (Moyo, 2001). The main objectives of the FTLRP are to speed up
the identification of not less than five million hectares of land for compulsory acquisition for resettlement, to
on
accelerate the planning and demarcation of acquired land and settler emplacement on this land, and to provide
limited basic infrastructure and farmer support services (Moyo, 2006). Compulsory acquisition was largely to be
made from white commercial farmers, private companies, and absentee landlords. According to Moyo (2006),
FTLRP beneficiaries have been issued many different types of temporary licenses which the government intends
to convert, in time, to permanent leases. This uncertainty regarding tenure arrangements within the FTLRP has
been a source of tenure insecurity among FTLRP beneficiaries (Zikhali, 2008).
MATERIALS AND METHODS
Data sources and type: The study was carried out using secondary data. Unless otherwise specified all the data
was drawn from the Central Statistics Offices (CSO), Ministry of Finance (MOF) and Ministry of Agriculture
(MOA) of Zimbabwe. In this study annual time series data was used covering the period from 1980 to 2009.
data
The variables under consideration are real Gross Domestic Product, real government agricultural expenditure on
extension, real government agricultural expenditure on research and development, real governme agricultural
government
expenditure on credit assistance, real government expenditure on non agriculture, real investment expenditure, real
consumption expenditure and a dummy for FTLRP.
Model specification: A modified log linear growth model used by Fan, Hazel and Thorat (2000) was adopted for
and
this study. This is because it is the most appropriate model to ascertain the relationship between government
agricultural growth and economic performance in the country since it shows the relationship of the resources
(expenditure) used by government on agriculture and its contribution to the overall economy (GDP). Therefore,

these public expenditure, exports and imports data have been interpolated. The log linear regression model is as
.
follows:-
Log GDP = A0 + A1Log AE Ext + A2 Log AE R&D + A3 Log AE CA +A4 Log NAE + A5 Log I + A6 Log C + A7
FTLRP + u
Where Log GDP is the logarithm for Gross Domestic Product (GDP), A0 is a constant and A1, A2, A3, A4, A5, A6 and
A7 are parameters to be estimated. Log AE ext, Log AE R&D, AE CA, Log NAE, Log I and Log C are the

and development, government agricultural expenditure on credit assistance, government expenditure on non
agriculture, investment expenditure and consumption expenditure respectively. FTLRP is the dummy variable of
Fast track land reform programme and the letter u represents error term. The regression analyses will be
performed using Econometric-views 7 (
views (E-views 7) statistical package.
Variables used in the model: Gross Domestic Product (GDP) is the total of all expenditures on final goods and
services produced per period of time usually a year (Lipsey & Crystal, 1999). Government agricultural
expenditure (AE) is the amount of money which is allocated to the agricultural sector by the government (MOF,
2009). Government agricultural expenditure is composed of government expenditure on extension (AE Ext),
research and development (AE R&D) and credit assistance (AE CA). The overall impact of government
assistance
agricultural expenditure on GDP is expected to be positive since it is an injection into the circular flow of income.
However literature shows that the relationship is mixed. It can be positive, negative or const
constant.
Government expenditure on non agriculture (NAE) encompasses the amount of money which is allocated to other
sectors besides agriculture. In Zimbabwe, these sectors include mining, manufacturing, health, education, services,
electricity, construction and tourism. The overall impact of government expenditure on non agriculture on GDP is
expected to be positive if increased expenditure is as a result of increase in taxes. However if the increase in
expenditure non agriculture sector is as a result of diversion of taxes from agriculture (with higher elasticity of
diversion
production than non agriculture sector) then the overall impact will be negative.
Investment expenditure (I) is expenditure on capital goods. It includes gross private investment, which is the
value of output retained by the business sector, additions to the stock of residential housing and net change in
business inventories. Increase in investment expenditure is expected to increase GDP through the multiplier since
n
it is an injection into the circular flow of income. However investments affect production over time, and growth is
a gradual process.This means that there is a lag experienced between investment and the eventual economic
This
benefits. A positive relationship between investment expenditure and GDP is expected.
Consumption expenditure (C) is the flow of goods and services purchased by consumers for consumption
uses. If individuals increase their levels of consumption spending at each level of disposable income, the level of
f
aggregate expenditure increases. If the amount of consumption expenditure decreases, then GDP decreases.
Therefore consumption expenditure is expec to be positively related to GDP (Lipsey & Crystal, 1999)
expected Lipsey 1999).
The dummy variable of Fast track land reform programme (FTLRP) was included to capture the changes in
land ownership patterns in the country. The details of the FTLRP have already been well well-covered in Chapter 1
and 3. However data on actual transfers are still not available in a form that can be easily obtained and analyzed
at the national level. A dummy variable, which assigns a zero (0) value to periods prior to the implementation of
FTLRP in 1980 to 1999 and a value of 1 to the period from its inception (2000) to date, was incorporated to cater
for FTLRP.
The error term (u) is used to capture errors and misses in the relationships. The error term is justified on
)
omissions of the influence of innumerable chance events and measurable errors. A constant (A0) is included since
this ensures that the model will be unbiased that is the mean of the residuals will be exactly zero (Gujarati,
1995).

shows that real government agricultural expenditure on extension was fluctuating from 1980 to 2009 but it
generally increased from the period mostly due increase attributable to wages and salaries for extension services

(World Bank, 1991). There was a sharp increase in real government agricultural expenditure on extension during
1980 to 1988 but aggregate grain production was fluctuating over the period. A notable decline, however, was
experienced during ESAP (1990 to 1994) when support to agriculture declined considerably.

Real government agricultural expenditure on credit assistance, illustrated on Figure 3, fluctuated over the period
1980 to 2009. Just like government agricultural expenditure of extension, it also generally exhibits an overall
upward trend. It had two sharp declines, one from 1990 to 1994, during ESAP and another one in 1998 when the
funds were diverted to pay the war veterans after which it sharply increased after 1999.

Zimbabwe (1980-2009)
The trend of overall real agriculture expenditure by the government using data collected from CSO is illustrated
on Figure 5. It shows that real agriculture expenditure generally increased from 1980 to 2009 which can be
attributed mainly to increase in government agricultural expenditure on credit assistance as illustrated on Figure
5.1 and increase in government agricultural expenditure on extension as illustrated on Figure 5.2. From 1980 to
vernment
1990, real agricultural expenditure generally increased mainly due to growth with equity programme explained
in chapter one. However as a result of the introduction of ESAP in 1990, the amount of money allocated to
of
agriculture declined since it was one of the conditions of the programme. After the abolition of ESAP in 1995
agricultural expenditure steadily increased from 1994 until 2004. The steady increase was also su sustained as a
result of Agribank issuing more loans to smallholder farmers since 2000, and the introduction of the Farm
Mechanisation Programme by the RBZ in 2006.

Empirical Results
Unit root tests: Stationarity of the time series was tested using the Augmented Dickey Fuller Test (ADF). If the

absolute value of the ADF is less than the absolute critical value, the test accepts the null hypothesis that the
variable is not stationary. If the calculated ADF test statistic is greater than critical t-values, reject the null

hypothesis. The Unit Root tests were conducted on the 8 variables which are shown on Table 2 below.
The test statistics over the entire range at levels were less than the critical values for the ADF at 90% level

The Unit Root tests showed that all other variables except government agricultural expenditure on extension
required to be differenced in order to become stationary since the absolute calculated ADF test statistics were

government agricultural expenditure on research and development, consumption expenditure and a dummy of
fast track land reform programme becomes stationary at 99% level of confidence after first differencing.
Government agricultural expenditure on extension variable was also stationary at 90% level of confidence. This
means that all the mean, variance and auto covariance at various lags remain the same no matter at what point we
measure them.
Johansen cointegration tests: The series for all the variables in the model used were tested for cointegration
using the trace tests and maximum eigenvalue tests as explained on 4.4.9. Although the trace test indicate that
the 5 cointegrating variables and the maximum eigenvalue tests indicates that there are 4 cointegrating variables,
on Table 3, both indicates that the real GDP and the explanatory variables are cointegrated at 95% le level of
confidence. The detailed results obtained from the cointegration tests are shown on Appendix J.

from the regression are shown on Appendix E. The whole model is scrutinised according to R2. Both R2 and
adjusted-R2 show quite significant outcomes at 93.7% and 91.5%, respectively. The adjusted R2 of 0.915104
implies that about 92 % of the variations in GDP are explained by the explanatory variables (real government
agricultural expenditure on extension, real government agricultural expenditure on credit assistance, real
government agricultural expenditure on research and development, real government non agricultural expenditure,

The results show that there is a negative relationship between real GDP and government agricultural

expenditure on extension. The coefficient of -0.213348 means that for every one percent increase in real
government agricultural expenditure on extension, re GDP decreases by 0.21% on average using the data from

1980 to 2009. This may have occurred as a result of information passed to farmers which was not appropriate to
Zimbabwe’s conditions. The p-value for real government agricultural expenditure on exten
value extension is 0.0002. It
shows that the variable is significant at all levels. This shows that the variable real government agricultural
expenditure on extension is significant in explaining real GDP since the absolute value of t t-value exceeds 2. The
variable is said to be statistically significant since the test statistic lies in the rejection region. However these
results contradicts the findings by Eyo (2008) which shows that public credit to the agricultural sector was
statistically insignificant in explaining agricultural growth and ultimately economic growth.

The variable for government agricultural expenditure on credit assistance was found to be negatively related to
economic growth and statistically significant at 95 percent confidence level. This might be due to the fact that

most farmers who received loans for farming purposes diverted funds to speculative purposes and therefore

experienced in 1992, 1995 and 2002 undoubtedly affected not only agriculture but the entire economy.
A positive relationship between real GDP and government agricultural expenditure on research and

Real investment expenditure shows a positive relationship with real GDP. It has a coefficient of 0.209728
meaning that a one percent increase in real investment expenditure increases real GDP by 0.2097 %. This is
supported by Fan and Rao (2003) who said that for economic growth to be achieved, investments in agriculture

Investment has proved to be a statistically significant variable with a t statistic of 8.439656 which is greater than

2 (following the rule of thumb). This suggests that investment is essential in trying to increase GDP.
Consumption turned to be positively related to be positively related to GDP. However this variable was

found to be statistically insignificant since the t statistic is less than 2. This is in contradiction with the findings
t-statistic
of Fan, Hazel and Thorat (2000) since they found the variable to be significant. Consumption may have been
found to be relatively insignificant because of underestimation of this variable by the Central Statistical Office
due to the error of omission when the data was collected since the informal sector is dominant but is not
considered when the data is collected.
The dummy variable for FTLRP shows that it is negatively related to economic growth but the variable
indicates that it is statistically insignificant since variable has a tt-statistic absolute value of 1.66 which is less

than 2 (following the rule of thumb) hence no meaningful inferences could be drawn from the relationship.
These results contradict to those found by Pender et al, (2001) in which they concluded that land redistribution in

the Amhara region had promoted more intensive crop production which led to improved living standards of the
occupants thereby positively contributing significantly to the Ethiopian economy
CONCLUSION
The main thrust of this study was to try to assess the impact of government expenditure on three functions of
agriculture on economic growth in Zimbabwe. It was to find out whether increase in expenditure on functions of
agriculture by the government increases or decreases GDP.
Results from the empirical analyses provide strong evidence indicating that agriculture is an engine of economic
growth. Basing on the results of this study, it can be concluded that government expenditure on functions of
agriculture affect economic growth significantly though differently. Real government agricultural expenditure on
