This research provides one of the first empirical estimates of a data-based dynamic factor demand model for American and Canadian agriculture. Models such as these deserve more widespread use in the empirical analysis of agriculture. These models have the advantage that they do not impose inappropriate dynamics on the data. Rather they permit the data to select the appropriate dynamics. We use a model originally developed by Anderson and Blundell. This model is a general first-order dynamic model which contains as testable hypothesis several simpler models. This model permits us to estimate the long-run agricultural production structure as a subset of the dynamic parameter estimates. We will test this long-run structure for symmetry, homotheticity and neutral technical change. The estimated models may be used to test for three alternative dynamic structures. In the limit, dynamics may not be needed and we can test for the static long-run equilibrium model. Two intermediate cases are the autoregressive and the partial adjustment models which are simpler than the general model but still include dynamics. Our results suggest that the long-run equilibrium model is unsatisfactory in both countries. A dynamic model is needed. In both countries, the two more restricted dynamic models are rejected. The general dynamic model is required. In Canada, the long-run equilibrium structure is homothetic with neutral technical change. In the United States, homotheticity is also accepted but neutral technical change is rejected.  相似文献

Impacts of agricultural and nonagricultural trade liberalization on agriculture are assessed in a multi-commodity, multi-country framework. By modeling simultaneously all goods sectors of the economy, we evaluate the importance of: (a) relative price changes between sectors, and (b) income and exchange-rate adjustments that follow trade liberalization in a world of floating rates. Specifically, we compare two cases using a static world policy simulation (SWOPSIM) model: agricultural multilateral liberalization and complete multilateral liberalization with floating exchange rates for all countries/regions. In both cases agricultural commodity prices tend to increase, an effect which is more pronounced when currency values adjust. The developing countries, in particular Argentina, Brazil and Mexico, have the most significant advances in agricultural and total production when exchange rates vary. Moreover, the gains from international trade are extended to all countries/regions explicitly specified in the model.  相似文献

This paper reports the results of a study of the economic content and the decision-making process of the recently adopted U.S. 1990 agricultural and food policy. It is the most comprehensive policy of its type. It represents the broadest participation of private individuals and interests groups, and will affect the economy of not only the United States, but also the ***economies of trading countries around the world. The study examines the economic conditions leading up to the policy, a theoretical foundation of public policy determinants, the role of economic analysis in that policy development, the provisions of the Act compared with the previous policy, and its extensive economic implications. Results of the study support features of a conceptual framework for economic policy of a participatory government. The study also reveals the unique policy process of the United States and the provisions of its price and income policy for the food and agricultural sector. Finally, this article identifies the interrelations between the 1990 policy and on-going GATT negotiations, the emerging importance of environmental and food quality issues in agricultural and food policy, and sources for further study of this Act.  相似文献

Environmental cross‐compliance links agricultural program payments to producer commitments to achieve agri‐environmental policy goals. The objective of this study is to determine the feasibility of using cross‐compliance to achieve environmental goals in a Canadian policy context. While Canadian policy makers have flirted with cross‐compliance, with the exception of phosphorus regulations for Quebec hog farms, they have never adopted this approach. The potential for effective cross‐compliance depends on producer participation, producer compliance with regulations, environmental performance, and overall welfare implications. This study reviews the application of cross‐compliance in the United States and EU with regard to the potential application to Canadian agriculture. Policy options are considered which link current business risk management (BRM) programs to alternative environmental regulations (wildlife habitat preservation, nutrient management plans, and beneficial management practices for nutrient management). In general, individual Canadian agricultural support program do not provide sufficient incentives for farmers to participate in cross‐compliance. However, if support programs are combined, it is better to link programs that redistribute income with environmental programs than to link agriculture programs that already address specific market failures.  相似文献

Transition and agricultural labor   总被引:2,自引:0,他引:2  
Reforms have strongly affected agricultural employment in transition countries but in remarkably different ways. We present a theoretical model and an empirical analysis to explain differences in labor adjustment during transition. We show that the differences are due to a combination of variations in initial conditions and differences in reform policies and effects. The removal of price distortions and subsidies caused wage and price adjustments during transition and a reduction in labor demand in agriculture. Surplus labor outflow from agriculture was further stimulated by the privatization of the farm assets as they improve incentives and remove constraints for optimal factor allocation and structural adjustment. The shift to individual farms, which was especially strong in labor‐intensive production systems with low labor productivity in agriculture, has reduced the outflow of labor from agriculture by improving farm governance and labor efficiency, although this effect was mitigated by losses in scale economies due to disruptions and market imperfections in transition. In general, labor outflow was considerably lower on individual farms than on corporate farms, due to a combination of factors related to human capital, access to finance, and physical capital. In the last section of the article we present a general framework for understanding labor adjustments in transition countries. Specifically, we show that there are several patterns of labor transition. In one pattern, followed by, e.g., the Czech Republic and Hungary, there is initially a strong survival of the restructured large‐scale corporate farms that have laid off many workers. In the second phase of transition, gradually the importance of individual farms increases. In other countries, such as Romania, the opposite has happened. In these countries there is an immediate strong shift to individual farms, while labor use increases on average in agriculture. After this initial phase, the shift to individual farms continues, albeit more slowly, and labor use in agriculture starts to decline. Finally, our analysis shows that in countries such as Russia and Ukraine much of the surplus labor is still employed by little‐reformed former collective and state farms. Major adjustments await more progress in agricultural and general reforms.  相似文献

This paper clarifies the factors determining the welfare effects of improved agricultural technologies when technology diffusion is unevenly distributed across production environments Household-level income effects are shown to depend primarily on: (a) whether the economy is open or closed with respect to world markets; (b) whether households are net consumers or net producers of the commodity for which technological change occurs; (c) whether households are adopters or non-adopters of the new technology; (d) the degree to which labor is mobile across agricultural regions; and (e) government intervention in commodity and/or factor markets. A review of recent empirical work indicates considerable variation in the relative strength of these various factors across countries, and that assumptions regarding the mechanism by which commodity prices are determined – endogenously as in a closed economy, or exogenously as in an open economy – is especially critical.  相似文献

In this investigation estimated relationships of resource markets for United States agriculture are used in a simulation model to study resource demand and farm income under three conditions: (a) those actually prevailing, including the historic mix of agricultural policies, (b) with technical change in agriculture only half the rate realized, and (c) with a free market. The results indicate that compared with “actual” conditions the environment of slow technical change would have modest effects in slowing the demand for farm machinery and the migration of labor from agriculture. It also would result in greater net farm income in the 1960's. A free market would be accompanied by increased investment in farm machinery and a greater exodus of family and hired labor from agriculture. It also would result in a smaller farm building investment and a considerable reduction of farm income. Since economic conditions are so similar in both countries, the implications of these findings are related to Canadian agriculture on the assumption the same model would show the same outcomes for Canada. Dans cette étude, des rapports estimés des marchés des ressources pour ?agriculture des Etats-Uns sont employés dans un modéle de simulation afin ?étudier la demande des ressources et le revenu agricol net sous trois conditions: (a) celle qui régne réellement, incluant le mélange historique de politiques agricoles; (b) celle qui ne montre le changement technique de ?agriculture qti à la moitié du train realise; et (c) celle qui profite ?un marché libre. Les résultats indiquent que ?enrironnement du changement technique modéré, quand il est compareé avec les conditions réelles, produirait des effets modestes en diminuant la demande pour des machines agricoles et en ralentissant ?exode de la main-?oeuvre de ?agriculture. En outre, cet environment aurait pour résultat un revenu agricole net plus fort dans les années de 1060 à 1970. Vne marché libre serait accompangne de placements augmentés dans les machines agricoles et ?un plus grand exode de la main ?oeuvre familiale et salariée de ?agriculture. Aussi, ceci aboutirait à un investissement moindre dans la construction rurale et à une réduction considérable du revenu agricole. Puisque les conditions économiques des deux pays sont si ressemblantes, les implications de ces conclusions sont rattachées à?agriculture cana-dienne en supposant que le même modéle montrerait les mêmes résultats pour le Canada.  相似文献

How to reduce poverty in lagging regions remains much debated and underserved with solid empirical evidence. This study illustrates an empirical methodology to analyze the pathways households followed out of poverty and to explore their potential in the future using 2000–2004 rural household panel data from two lagging provinces of China, Inner Mongolia and Gansu. It finds that rising labor productivity in agriculture has been key in understanding poverty reduction in rural lagging areas of these provinces and that it still holds much promise. Circular migration has also been important in Gansu, though less so in Inner Mongolia. On average, rural diversification has not proven to contribute much to poverty reduction and income transfers and agricultural tax abolishment have only helped at the margin. The findings from these two case studies highlight that the scope for reducing poverty in rural lagging regions can still be substantial in agriculture, also when nonagriculture drives national growth.  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

Most studies of agricultural transformation document the impact of agricultural income growth on macroeconomic indicators of development. Much less is known about the micro-scale changes within the farming sector that signal a transformation precipitated by agricultural income growth. This study provides a comparative analysis of the patterns of micro-level changes that occur among small-holder farmers in Uganda and Malawi in Sub-Saharan Africa (SSA), and Thailand and Vietnam in Southeast Asia (SEA). Our analysis provides several important insights on agricultural transformation in these two regions. First, agricultural income in all examined countries is vulnerable to changes in precipitation and temperature, an effect that is nonlinear and asymmetric. SSA countries are more vulnerable to these weather changes. Second, exogenous increases in agricultural income in previous years improve non-farm income and trigger a change in labor allocation within the rural sector in SEA. However, this is the opposite in SSA where the increase in agricultural income reduces non-farm income, indicating a substitution effect between farm and non-farm sectors. These findings reveal clear agricultural transformation driven by agricultural income in SEA but no similar evidence in SSA.  相似文献

Short‐run responses of export and domestic shares of total agricultural output to changes in stocks of domestic savings (SAV), development assistance (ODA), private foreign commercial capital (PFX) and other variables is investigated. A profit function approach is used. Time series data for 19 sub‐Saharan African countries are pooled into three panels using similarities in changes in economic policy regime. Statistical evidence suggests that for the panel of countries that were undertaking liberalized economic reforms, the slope coefficients of some of the variables in the models have changed significantly between 1970–1980 and 1981–1993. For the 1981–1993 period, the impacts of ODA, PFX and SAV on export and domestic shares were different for this panel. The effect of increases in agricultural labor was different across the three panels. There is also evidence that productivity growth in the export agriculture sub‐sector is negative in all the groups. It is recommended that to halt the decline in export share of agricultural output in the group of countries that have undertaken substantial improvements in economic policy environment, efforts must be made to reduce the negative impact of domestic savings and agricultural labor, while at the same time working to reduce the bias of development assistance against food security.  相似文献

This paper utilizes a world spatial equilibrium model to examine the effects of U.S.–Canadian softwood lumber disputes on U.S., Canadian, and other exporters' and importers' lumber markets. Results show that the U.S. import tariff on Canadian softwood lumber impacts prices, supply, demand and trade flows not only in the United States and Canada but also in the other countries. Though the goal of U.S. trade restriction is to limit imports from Canada and protect its producers, the United States cannot fully accomplish this goal as non-Canadian exporters fill the void left by the reduced imports from Canada. Canadian producers lose from the U.S. policy, but their loss is mitigated as Canada redirects its exports to other importers. Importing countries such as Japan and the European Union benefit from the U.S. trade restrictions as Canada seeks to sell its softwood lumber to these countries.  相似文献

Agricultural land expansion is a prominent feature in today’s developing countries. It is associated with a structural pattern of land use in many remote land-abundant regions where large-scale commercial primary product activities coexist with increased concentration of smallholders in more marginal areas. The result may be boom-bust cycles of development. If these phenomena are widespread across developing countries, then long-run expansion of agricultural land could be associated with lower levels of real income per capita, which may also fluctuate with prolonged expansion. A panel analysis conducted over 1961–2015 for 98 developing economies fails to reject this hypothesis. Policies should aim to decouple socio-economic gains through agricultural development from continued land expansion, and greater investments are needed to support smallholder agriculture, land distribution and livelihoods in these areas.  相似文献

This study examines the induced innovation hypothesis (IIH) from 1958 to 2015 for two Canadian agriculture regions: Central Canada (the provinces of Ontario and Quebec) and Western Canada (the provinces of Alberta, Saskatchewan and Manitoba). There is broadly consistent support for the IIH for Canadian agriculture, especially for Western Canadian agriculture. In addition, there is support for the notion that US, as well as Canadian, research expenditures are important to explain changes in the input ratio in Canadian agriculture in the long run. This indicates the existence of spillover effects from US agricultural research expenditures to Canadian agriculture.  相似文献

The objective of this study is to gain a better understanding of factor substitutions in postwar Japanese agriculture by shedding special light on biased technological change. Such biased technological change is first measured, then associated with the movements of factor prices, and then tested for the Hicksian induced-innovation hypothesis. In addition, a decomposition analysis is carried out in order to quantitatively examine the importance of the biased effects for determining changes in factor-cost shares and factor proportions during the 1958-84 period. A slightly modified Stevenson-Greene model of the translog cost function is employed. This model has at least two important advantages over ordinary translog cost functions. First, it incorporates time into the model such that all coefficients of the ordinary translog cost function may change over time. This is more realistic than the ordinary translog cost function which assumes that all coefficients are constant over the period of estimation. Another attractive feature is that it enables us to test the induced-innovation hypothesis directly. The model is applied to the 1958-84 period by making use of farm-level data. The results show that technological change was biased towards saving labor and other inputs and using machinery, intermediate inputs, and land. This biased technological change is found to be, in principle, consistent with the induced-innovation hypothesis. Furthermore, it is shown through decomposition analyses that the biased technological change had significant impacts on changes in factor-cost shares and factor proportions during these years. The empirical results of this study imply that technological change in Japanese agriculture has, in general, proceeded in a manner consistent with factor endowments conditions since the late 1950s. An implication of this study for agriculture in less-developed countries is that agricultural policies seeking development through technological progress should be carried out so as to take advantage of peculiar factor endowments conditions in the individual countries.  相似文献
