The empirical literature on farmer cooperatives is now fast emerging and developing in the areas of performance, ownership and governance, finance, and member attitude. We discuss 56 peer‐reviewed publications to illustrate the main findings and conclusions while outlining challenges and opportunities for future research. Generally, cooperative membership is found to positively impact price, yield, input adoption, income, and other indicators of member performance, yet there is growing evidence of an uneven distribution of benefits for small and large producers. In terms of structure, evidence of a causal relationship of ownership and governance to performance has been elusive, yet there are now many findings of inherent equity and long‐term debt constraints, often in the context of consolidation to drive scale and scope economies. Further inefficiency is observed to be driven by increased heterogeneity in member attitudes and objectives, in particular in terms of commitment and participation. Thus, overall, empirical work portrays farmer cooperatives as flawed and complex business organizations which nonetheless have a strong positive impact on its members. While applied research may progress in various directions, a general improvement in empirical methodologies is needed to allow robust analysis of mixed objectives in dynamic environments.  相似文献

Agricultural cooperatives in Africa tend to be community‐based organizations defined by principles of inclusion, voluntarism, democracy, equity, autonomy, mutuality and solidarity. This means that they generally operate in accordance with the principles endorsed by the International Cooperative Alliance (ICA). However, only a few of these organizations are successful in commercializing the agricultural produce of their members. In this study, we argue that growth‐problems leading to commercial failure and organizational degeneration in these cooperatives can be attributed to a lack of managerial capital. Drawing on the literature and evidence from the field we set out key management solutions for counterbalancing cooperative principles in the context of rural Africa. These solutions were taught to the leaders and managers of 362 cooperatives at four training events held in Madagascar, Malawi and twice in Uganda. Using a production function for cognitive achievement and key informant interviews, we find that our training contributed to the adoption of the proposed solutions by some of the cooperatives. Using the Ugandan sub‐ sample, we estimate an OLS regression and a PSM model to show that the training translated into higher revenues per member generated through collective commercialization.  相似文献

Since the 1990s, Argentinean dairy‐processing cooperatives have lost considerable amounts of members and market share. We analyse their current role by investigating the characteristics of farmers who continue delivering to them and price differentials between cooperatives and investor‐oriented firms (IOFs). A probit regression model applied to 917 farmers suggests that cooperative farmers are more disadvantaged than farmers delivering to IOFs in terms of education, farm size and productive technology. Moreover, t‐tests applied to data representing 70 per cent of national volume indicate that farmers delivering to cooperatives are between 11 per cent and 29 per cent smaller than those delivering to IOFs, depending on province. A hierarchical multilevel regression model applied to 9,720 transactions among farmers and processors shows that, after controlling for quantity and quality, cooperatives pay lower (3.5%) but more stable prices than IOFs. In a context of rapid structural change, we observe a market in which larger farmers deliver to IOFs and smaller farmers deliver to cooperatives and conclude that, at the expense of paying lower prices, cooperatives may act as buyers of last resort for otherwise disadvantaged farmers.  相似文献

We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high.  相似文献

This paper investigates the effect of political factors on the interregional allocation of the budget to assist farmers in coping with agricultural trade liberalization in Japan. We present a simple model to show the relationship between political factors and interregional budget allocation and empirically examine whether political factors played a key role in the interregional allocation of Japanese government spending for the Uruguay Round agricultural trade liberalization. Our findings show that this allocation was distorted due to political reasons, which was problematic from the standpoints of fairness and social efficiency.  相似文献

This paper develops a real options model of an all-equity financed firm that receives mean-reverting earnings and is subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold such that the firm pays no corporate income taxes should its earnings be less than this threshold. The firm possesses a perpetual option to liquidate its operation for a deterministic salvage value at any time. We show that the firm optimally exercises the liquidation option at the first instant when its earnings reach an endogenously determined threshold (the liquidation trigger) from above. Using numerical analysis, we show that the liquidation trigger is higher or lower than the exogenously given tax exemption threshold, depending on whether the tax exemption is below or above a unique critical level, respectively. We further show that the liquidation trigger is strictly decreasing for all tax exemption thresholds less than the critical level, and can be hump-shaped for all tax exemption thresholds greater than the critical level, especially when the salvage value is small. Corporate income taxes as such are not neutral when tax schedules are progressive.  相似文献

According to empirical studies, speculators place significant orders in commodity markets and may cause bubbles and crashes. This paper develops a cobweb-like commodity market model that takes into account the behavior of technical and fundamental speculators. We show that interactions between consumers, producers and heterogeneous speculators may produce price dynamics which mimics the cyclical price motion of actual commodity markets, i.e., irregular switches between bullish and bearish price developments. Moreover, we find that the impact of speculators on price dynamics is non-trivial: depending on the market structure, speculative transactions may either be beneficial or harmful for market stability.  相似文献

Pricing-to-market (PTM) theory suggests that exporting monopolistic firms adjust their destination-specific mark-ups in the face of exchange rate shocks. A large proportion of the existing evidence for PTM comes from Wald tests applied to OLS- and IV-estimated parameters of single-equation models. Such tests can seriously over-reject in the presence of endogeneity and weak instruments so that some of the available results supporting PTM could be spurious. In this paper we revisit the PTM evidence for Japanese and German exporting firms in the transportation equipment industry. Using the model of Marston (1990), we apply exogeneity and LR-LIML-based tests for which the error probability is controlled irrespective of the quality of the available instruments. Our results show right-hand-side endogeneity in almost all of the examined PTM equations. In addition, we find that statistical decisions often differ depending on whether they are based on the traditional Wald test or on our proposed test.The authors would like to thank Philippe Barla, Jean-Thomas Bernard, Christos Constantatos, Larry Schembri, seminar participants at the Bank of Canada, and two anonymous referees for useful comments and suggestions. Thanks also to Richard Marston for providing data. Finally, a special thanks to Marjorie Santos for excellent research assistance. All remaining errors are our own and should not be attributed to the Bank of Canada.First version received: May 2002/Final version received: December 2002  相似文献

This paper estimates a VAR including labor productivity, real wage and unemployment rate, to identify the dynamic effects of technology, demand, and mark-up shocks, respectively, on the Italian labor market. Identification is achieved by imposing recursive restrictions on the matrix of long run multipliers. Our results show that both mark up and aggregate demand shocks permanently reduce the unemployment rate. Finally, technology shocks do not significantly affect the unemployment rate in the long run. These findings convey important policy implications: expansionary aggregate demand and deregulation policies reducing the mark up permanently decrease the Italian unemployment rate.Jel classification: C32, E32, J29This paper has been produced as part of a CEPR Research Network on New Approaches to the Study of Economic Fluctuations.
