The sustainability of farming systems is currently under debate. There is concern that technological and other changes have long-run consequences, which may compromise future levels of desired outputs from agricultural and other resources. The paper traces developments in the theory of sustainability and discusses their application at the farm level. Findings include firstly, that sustainability should be regarded as an emergent property of an agricultural system. Its operational definition at the farm level thus may not apply at other levels in the hierarchy. Secondly, whilst individual farmers may attach value to “sustainability” goods, they are unlikely to adopt socially optimal levels without regulation or incentive. Finally, since sustainability issues at the farm level are usually long-run, dynamic and have social dimensions, a central task for farm management researchers lies in investigations which allow tradeoffs between different sustainability criteria to be determined and then optimised according to society's norms. 相似文献

Specialization,diversification, and productivity: a panel data analysis of rice farms in Korea 总被引:1,自引:0,他引:1

This article examines the microeconomics of productivity associated with specialization/diversification in production activities, with an application to Korean rice farms. Korean rice farms tend to be very small and highly specialized. Our analysis examines the productivity effects associated with both farm size and farm specialization/diversification in Korean agriculture. Relying on farm‐level panel data, the analysis studies farm productivity in a multi‐input multi‐output context, accounting not only for changes in inputs and technical change in rice production, but also for the role of diversification in the production of other crops in current and previous periods. We find positive but small productivity gains from farm diversification. These gains come mostly from complementarity effects across farm outputs, with minimal effect of scale economies. The positive complementarity effects work against nonconvexity effects, which provide strong productivity incentives for rice farms to specialize. 相似文献

Evaluating agricultural programmes requires considering not only the programmes’ influence on input and output indicators, but also considering the relationship between these indicators as embodied in the production technology. This article examines the impact on production of an intervention in the Ecuadorian Sierra designed to improve returns to potato production through training and through linking smallholders to high‐value markets. Critical to identifying the impact of the programme is the careful construction of a counterfactual and meticulous data collection. To assess the impact of the programme on production, a weighted estimation, where weights are constructed through propensity score matching, is employed to estimate a production function within a damage abatement framework. The function incorporates a series of interaction terms to assess the impact of the programme on the production technology. The findings provide evidence that the programme enhances yields both through a general shift in technology as well as increased input use. The results suggest that the use of effective farming techniques that are learned through the programme induce this technological shift. 相似文献

This article discusses how the “decision style” of an administrator influences the adoption and use of particular decision models. Several “interactive” and “analytical” decision models often used to guide decision making are described and critiqued to point out their virtues and deficiencies. Propositions are suggested that contend that “systematic,” “judicial”, “speculative”, and “intuitive” styles have clear-cut preferences for a particular decision model. This model seems to be used, even when another would be more suitable. Effective decision makers are postulated to adapt their styles, or at least to see the benefits of different styles. Mixed-mode models are proposed that seem to simulate the behavior of successful decision makers. 相似文献

In 1977 the Foreign Corrupt Practices Act (FCPA) was enacted to penalize US firms and their employees for paying bribes to foreign government officials. If bribe payments influence the awarding of contracts and the FCPA regulation differentially affects US exporters compared to foreign competitors, then US exporters' bribe-paying ability and market share would be expected to decline. This study provides empirical evidence that the FCPA had a negative effect on US exports to non-Latin American countries but not to bribery prone ones in Latin America. 相似文献

We investigate migration and foreign direct investment (FDI) for a small trading economy. Historically, immigration in small countries has been accompanied by FDI inflows (complementary capital movements). Based on the skill composition of migrants, empirical evidence finds that skilled immigration is accompanied by FDI inflows but unskilled immigration is accompanied by FDI outflows (substitutable capital movements). We prove that the Heckscher-Ohlin model cannot reconcile these apparently contradictory observations. We introduce a theoretical model in which capital and unskilled labor are sector specific, and demonstrate that this model can reconcile the historical and empirical observations on migration and FDI. 相似文献

The creation of the Asian Infrastructure Investment Bank (AIIB)was welcomed by the World Bank but opposed by the Obamaadministration. The paper explains China’s positive relationshipwith the Bank and the Organization for Economic Cooperation andDevelopment (OECD) in terms of the mission of the Bank, sharedby the OECD, to develop and deepen the global economy. The AIIBand the related Belt and Road initiative promise to do this throughinvestment in infrastructure and connectivity in and around thepoorly integrated Eurasian landmass. But while the current Chineseleadership has supported an inclusive global economy based uponfree trade and supported by multilateral institutions, China’s controlof resources outside the multilateral framework and adherence topractices that challenge liberal principles prompt suspicions thatthese commitments are either disingenuous or anyway subjectto reversal. In itself, therefore, the AIIB provides no conclusiveevidence either way on China’s future course. 相似文献
