The objective of this study is to determine the financing impact of total expenditure on the use of agriculture inputs (fertilizers, labor, and pesticides), and the output of cotton, rice, beans, corn, soybean, and wheat in Brazil. We study the period 1976–2005. The analysis is based on duality applied to the production theory. The output supplies and conditioned input demands are estimated from a translog multi‐output, multi‐input restricted profit function, where the total production credit is used as proxy of the total expenditure. Farmer expectations with respect to crop prices are incorporated to the estimation based on the quasi‐rational expectation model. The output and input responses to the total expenditure are positive and statistically significant except for cotton, wheat, fertilizer, and pesticides. The short‐run output supply response to own prices is inelastic, except for wheat, which presents elastic response to its price. Acreage has a positive impact on the output supply and it is influenced by land productivity. The main conclusion is that farmers face budget restrictions to purchase inputs, and a government credit program might increase the agricultural supply.  相似文献

This article examines the role of institutional services of credit, input supply, and extension in the overall commercial transformation process of smallholder agriculture in Ethiopia. Survey data collected in 2006 from 309 sample households in three districts of Ethiopia are used for the analyses. Tobit regression models are used to measure the effect of access to services on the intensity of inputs use for fertilizer and agrochemicals. A probit model is used to measure these effects on the adoption of improved seeds. Intensity of use of seeds is analyzed using an ordinary least squares model. Logarithmic Cobb–Douglass functions are estimated to analyze the effect of access to services on crop productivity. Heckman's two‐stage estimation is used to examine determinants of household market participation and the extents of participation. Results show that access to institutional support services plays a significant role in enhancing smallholder productivity and market orientation. Our results imply that expanding and strengthening the institutional services is critical for the intensification and market orientation of smallholder agriculture in Ethiopia. In particular, appropriate incentives and regulatory systems are urgently needed to encourage the involvement of the private sector in the provision of agricultural services.  相似文献

In this paper, we develop an empirical model to decompose the evolution of the agricultural share of GDP into three components: price changes, factor endowment changes and technological change. Our results suggest that relative prices have a positive but small influence on the share of agriculture in GDP in both the long‐run and the short‐run. An increase in capital per unit of labor, on the other hand, is associated with a smaller agricultural share. Technical change has been biased in favor of the agricultural sector but this effect has been swamped by the magnitude of the input effects, in particular, the changes in the capital‐labor ratio.  相似文献

Growth in the agricultural GDP of four major European countries is compared with US agricultural growth for the period 1974–1993. The agricultural sector's relative prices are taken into account along with economy-wide factor market adjustments. For Denmark, France, Germany and the UK, the effects of declining real prices and changes in input levels on growth in agricultural GDP are relatively small. Total Factor Productivity (TFP) growth appears to be the major contributor to European agricultural GDP growth. In comparison, TFP is the major source of growth in US agricultural GDP, but its rate of growth is lower than the European countries. In contrast, the declining real prices for US agriculture had a relatively large effect on its GDP. However, in recent years, the effects of declining real prices and declining rates of growth in TFP on European agriculture are relatively large. In the longer-run, the relative competitiveness of US agriculture is largely dependent on its ability to sustain and increase growth in TFP.  相似文献

Indian agriculture is experiencing under-performance despite increased attention given to it in the recent past. This paper analyzes the disparities in agricultural growth across Indian states and explores the determinants of agricultural growth, using Panel Corrected Standard Error approach. Analysis using beta convergence shows that the disparities across the state's agricultural growth are narrowing down for the period 1980–1981 to 2011–2012. However, to stimulate growth in the states where agriculture is lagging behind, a higher emphasis on increasing the area under irrigation, expenditure on agricultural research, area under fruits and vegetables, number of regulated markets, length of roads, cold storage facilities and institutional credit for investment purposes is needed. Private sector should be involved in public–private-partnership mode for improving the infrastructure in this sector.  相似文献

黑龙江省农业碳排放、科技投入与经济增长关系研究   总被引:1,自引:0,他引:1  
[目的]以黑龙江省为例,首先对其农业碳排放总量进行测度,再研究农业碳排放同经济增长、科技投入之间的关系。[方法]利用1996~2013年的统计数据,从4个方面估算了黑龙江省农业碳排放量,进而采用自回归滞后分布模型(ARDL模型)对农业碳排放量、经济增长以及科技投入之间的关系进行实证分析。[结果]农业碳排放量、GDP增长和科技投入存在长期稳定关系,但长期来讲农业碳排放量增长速率远大于GDP增长速率;GDP增长对农业碳排放总量存在显著的正向影响,且长期影响程度远大于短期;科技投入对农业碳排放具有抑制作用且存在滞后效应,其中长期的抑制作用为12.4%,短期为3.9%,当滞后期为两年时,抑制作用尤为显著。[结论]经济增长会促进黑龙江省农业碳排放的增加,而科技投入则能对农业碳排放产生有效地抑制作用,因而黑龙江省可以通过增加农业科技投入来降低农业碳排放。  相似文献

Restrictions on input use frequently accompany the granting of institutional credit to farmers in developing agriculture. A general economic framework is suggested to analyze the net social benefits of such a policy. The paper discusses the potential for manipulating the policy variables to foster more rapid adoption of new agricultural technology. An empirical analysis of the impact of a supervised credit programme in Guatemala on farm performance and farmer decision-making is presented.  相似文献

Climate‐smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under climate change. Few studies, however, quantify at the national scale CSA's economic effects or compare CSA to input‐intensive technologies, like fertilizer or irrigation. Such quantification may help with priority setting among competing agricultural investment options. Our study uses an integrated biophysical and economic modeling approach to quantify and contrast the economywide effects of CSA (integrated soil fertility management in our study) and input‐intensive technologies in Ethiopia's cereal systems. We simulate impacts for 20‐year sequences of variable weather, with and without climate change. Results indicate that adopting CSA on 25% of Ethiopia's maize and wheat land increases annual gross domestic product (GDP) by an average 0.18% (US$49.8 million) and reduces the national poverty rate by 0.15 percentage points (112,100 people). CSA is more effective than doubling fertilizer use on the same area, which increases GDP by US$33.0 million and assists 75,300 people out of poverty. CSA and fertilizer have some substitutability, but CSA and irrigation appear complementary. Although not a panacea for food security concerns, greater adoption of CSA in Ethiopia could deliver economic gains but would need substantial tailoring to farmer‐specific contexts.  相似文献

In this article, we analyze the role of subsistence‐oriented agriculture in Russia in the 1990s. We start out by discussing the diverging economic effects of the growth of subsistence agriculture in Russia since the transition process started. The quantitative analysis of this sector's role is carried out by means of an applied computable general equilibrium (CGE) model applying a 1994 social accounting matrix (SAM) as base year data. The novelty of the article is to disaggregate primary agricultural production not by products but by farm types, which enables us to distinguish their institutional and economic characteristics. The model also explicitly differentiates between marketed and subsistence consumption or formal and informal marketing activities of agricultural producers. We simulate two ex post and two ex ante experiments. The results of the first backward‐looking experiment highlight that Russia's subsistence agriculture was an important buffer against further agricultural output declines during transition and, hence, against food insecurity. A simulation, which looks into the effects of a devaluation of the Russian ruble, shows that the financial crisis should have increased the relative competitiveness particularly of large‐scale crop farms versus small‐scale farms. Two forward‐looking experiments indicate that efficiency enhancing institutional change would benefit both large‐scale and small‐scale farms. However, within small‐scale agriculture, a shift from subsistence to commercial agriculture would take place.  相似文献

We use Brazilian agricultural censuses data since 1970 to describe land structure evolution in Brazil, focusing on the most important agricultural commodities and livestock products across regions. The analysis reveals a remarkable stability in the number of farms in the period, as well as in the structure of land distribution across farm sizes, with a persistence of a dual agricultural structure. Land distribution, as measured by the GINI index, has changed very little and is still very high. The number of large farms is increasing significantly in time, while the number of farms with area below 500 ha changed little in the 1970–2006 period. Medium‐sized and large farms, although heavily outweighed in numbers, account for the highest share of annual crop production currently, and their share in crop (annual plus permanent) production value increased between 1980 and 2006, while the same share decreased for smaller farms. We conclude that the observed stability will probably reduce in the future, as economic forces will likely change the balance in favor of an increase in the number of large farms. This is an issue of obvious political importance, especially considering the importance of the smaller farms for employment in agriculture.  相似文献

This article presents multi-output, multi-input total factor productivity (TFP) growth rates in agriculture for 88 countries over the 1970–2001 period, estimated with both stochastic frontier analysis (SFA) and the more commonly employed data envelopment analysis (DEA). We find results with SFA to be more plausible than with DEA, and use them to analyze trends across countries and the determinants of TFP growth in developing countries. The central finding is that policy and institutional variables, including public agricultural expenditure and proagricultural price policy reforms, are significant correlates of TFP growth. The most significant geographic correlate of TFP growth is distance to the nearest OECD country.  相似文献

This article investigates the link between financing and investment in Ukrainian agriculture during economic transition. The main contribution of the study is to provide empirical evidence for the coexistence of financial constraints and soft budget constraints (SBCs). This is of particular importance because credit constraints and SBCs have completely different economic effects. The lack of differentiation between these forms of capital market imperfections yields overlapping effects of financing on investment and may therefore cause a misinterpretation of econometric results. Our empirical analyses are based on an econometric estimation of the Euler investment equations for 529 large farms from three Ukrainian regions between 2001 and 2005. The results confirm that financial variables significantly influence farms' investment, providing empirical evidence of an imperfect capital market in Ukrainian agriculture. It turns out that credit constraints in the Ukrainian agricultural sector are more important than SBCs. We show that the estimated level of financial constraints for profitable farms with access to loans is higher if both types of capital market imperfections are appropriately distinguished.  相似文献

This study develops a microeconometric model of specialized dairy farms in the Moscow region using panel data over the period 1995–2001. The model is used to analyze the role of subsidies on profit as well as input and output allocation. Theoretical conditions for short‐term profit maximization are not rejected by the data. Differences between farms allow for a fixed‐effect specification. The dairy producers in the region demonstrate a low responsiveness to market signals, but technology change becomes important. Labor, land, and livestock had low shadow prices. Although subsidies have a distorting effect on the input–output mix, this study shows they relieve the credit constraints on dairy farms and have an important positive influence on farm profit.  相似文献

Agriculture in transition economies: from common heritage to divergence   总被引:3,自引:0,他引:3  
The 23 former socialist countries in Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS) started the transition in 1989–1990 from a common institutional and organizational heritage, represented by the Soviet agricultural model. Despite the common heritage in agriculture, the reform policies in CEE and CIS diverged from the start, as significant differences emerged between the two groups of countries in legal attitudes to private land ownership, transferability of land, the extent of agricultural privatization and individualization, and restructuring of farms. This divergence in the implementation of agricultural reform has led to divergence in standard development measures: the CEE countries are outperforming the CIS countries by growth in GDP and agricultural product since 1992; the productivity of agricultural labor in CEE is generally increasing, and in CIS it is decreasing. While the CIS countries at best can be characterized as reluctant reformers, the CEE countries have achieved significantly higher levels of economic and institutional reform. Better performance in CEE is associated with greater readiness of the governments in these countries to implement a comprehensive package of economic and social reform policies, including more radical land reform and deeper individualization and restructuring of agriculture.  相似文献

Many mechanized crop producers and agribusinesses are fascinated with precision agriculture technology, but adoption has lagged behind the expectations. Among the reasons for slow adoption of precision agriculture technology is that initial users focused excessively on in‐field benefits from variable‐rate fertilizer application using regional average fertilizer recommendations. This article illustrates how greater use of site‐specific crop response information can improve variable rate input application recommendations. Precision agriculture is spatial information technology applied to agriculture. The technologies include global position systems (GPS), geographic information systems (GIS), yield monitoring sensors, and computer controlled within‐field variable rate application (VRA) equipment. Experimentation with these technologies is occurring everywhere there is large scale mechanized agriculture. Commercial use has been greatest in the US, where 43% of farm retailers offered VRA services in 2001. Except for certain high‐value crops like sugar beet, farmer adoption of VRA has been modest. The farm level profitability of VRA continues to be questionable for bulk commodity crops. The theoretical model and illustration presented here suggest that VRA fertilization has not yet reached its profitability potential. Most VKA field trials to date have relied upon existing state‐wide or regional input rate recommendations. Unobserved soil characteristics can potentially interact with an input to make its effect on yield vary site‐specifically within fields. Failure to use site‐specific response functions for VRA applications may lead to a misallocation of inputs just as great as that which results from using uniform applications instead of VRA. Agricultural economists have a long history of estimating output response to input applications. Several have started to develop tools to estimate site‐specific responses from yield monitor and other precision agriculture data. Likewise, agricultural economists have developed an important body of research results on information value based on managing variability—typically in temporal settings. With these tools, a major potential exists to develop further benefits from precision agriculture technologies that permit truly spatially tailored input applications.  相似文献

To improve the welfare of the rural poor and keep them in the countryside, the government of Botswana has been spending 40% of the value of agricultural GDP on agricultural support services. But can investment make smallholder agriculture prosperous in such adverse conditions? This paper derives an answer by applying a two‐output six‐input stochastic translog distance function, with inefficiency effects and biased technical change to panel data for the 18 districts and the commercial agricultural sector, from 1979 to 1996. This model demonstrates that herds are the most important input, followed by draft power, land and seeds. Multilateral indices for technical change, technical efficiency and total factor productivity (TFP) show that the technology level of the commercial agricultural sector is more than six times that of traditional agriculture and that the gap has been increasing, due to technological regression in traditional agriculture and modest progress in commercial agriculture. Since the levels of efficiency are similar, the same pattern is repeated by the TFP indices. This result highlights the policy dilemma of the trade‐off between efficiency and equity objectives.  相似文献

This article presents a bio‐economic household model, which has been developed to assess the potential impacts of agricultural intensification efforts on economic and ecological indicators in eastern Uganda. A study region in the Lake Victoria Crescent was selected with comparative advantages for intensive agricultural production: high agricultural potential, high market access, and high population density. However, current production is characterized by low input–output systems revealing a discrepancy between development opportunities and actual development outcomes. Based on a farmer participatory research approach, production methods were introduced in the study region aimed at fostering sustainable agricultural development. Data from two community surveys, two comprehensive household and plot level surveys, and farm‐trial data were used to develop and calibrate bio‐economic models for four representative household types. Model scenarios reveal that farm households in eastern Uganda would not pursue sustainable intensification under current socio‐economic conditions. The market environment has to be improved substantially, i.e., transaction and transportation costs have to be reduced, innovative credit schemes for smallholders have to be introduced, and alternative forms of labor acquisition have to be promoted, to provide sufficient economic incentives for the adoption of environmentally sound production methods. In addition, agricultural service provision needs to be reformed and more agricultural research is needed for new and better‐targeted technologies.  相似文献

The motivation for this study stems from two major concerns that are interlinked. The first is the decades long food insecurity crisis faced by sub‐Saharan African (SSA) countries which is still prevalent. The second is the negative impact greenhouse gas (GHG) emissions from agriculture may have on future food production and which is likely to worsen the food insecurity problem. The conundrum SSA farmers face is how to increase food output through productivity growth while minimizing GHG emissions. To measure changes in productivity growth and GHG emissions, this study evaluates the agricultural performance of 18 SSA countries by utilizing the Malmquist–Luenberger index to incorporate good and bad outputs for the years 1980–2012. The empirical evidence demonstrates that productivity is overestimated when bad outputs are not considered in the production model. The analysis provides a better understanding of the effectiveness of previous mitigation methods and which informs an appropriate course of action needed to achieve the twin objectives of increasing agriculture productivity while reducing GHG emissions.  相似文献

A stated objective of the Ethiopian Government since it came to power in 1975 has been to increase the production of crops for both domestic consumption and export. Consequently, a number of plans and programs have been proposed and implemented to bring about such development in Ethiopian agriculture. This paper mainly focuses 011 a macro review of the general course of Ethiopian agricultural development since the land reform of 1975. The food production in Ethiopia has lagged behind the population growth as evidenced by the gap between the growth rates of population (3%) and food production (1.8%) over the period from 1970 to 1983. Recently, this situation has, perhaps, further deteriorated. Seventy-one percent of the total land mass is estimated to be suitable for agriculture, but only about 19% is cultivated. This suggests an underutilisation of land. Moreover, Ethiopia has a persistent subsistence production problem in agriculture. Agricultural research and education which are essential to development have not been given due attention by the policy makers. As a result, the agricultural technologies used by farmers have changed little in this century. Moreover, small-scale farmers, although still the most potent economic force in the country, have not been given the incentives necessary to expand production, and currently receive less than adequate support from the central government. Some 85%, 50%, and 79% of total agricultural credit, fertiliser and improved seeds respectively go directly to socialist enterprises (state farms and producers' cooperatives) which, up to 1985, have jointly accounted for only 5% of the total cultivated land and 4% of the national crop production. The favouring of large-scale and capital-intensive state-owned farming enterprises with credit, subsidies, and fiscal incentives, while neglecting smallholders, has contributed to the stagnation of agricultural production in Ethiopia. Overall, the analysis indicates that there has been no significant development of agriculture in Ethiopia following the 1975 land reform.  相似文献

The Uruguay Round Agreement on agriculture attempted to lower distortions in global agricultural markets. However, the significant fall in commodity prices in the late 1990s may have reduced the incentives for both developed and developing countries to better integrate into world markets. This study analyzes price linkages and adjustment between developed and developing countries during the post–Uruguay Round period. Prices of two key commodities, long‐grain rice and medium‐hard wheat, are assembled for major exporters and producers. Results of multivariate cointegration analysis suggest partial market integration between developed and developing countries in the post–Uruguay Round period. Developed countries are found to be price leaders in these two markets, and in most cases, changes in their prices have relatively large impacts on those of the developing countries. Developing countries (e.g., Vietnam and Argentina) have faced considerable price adjustment due to changes in the developed countries' prices.  相似文献
