This paper proposes an extensive data simulation exercise on the likely impact of non-agricultural market access liberalization. The paper analyses real options for tariff cut reduction, special and differential treatment and the treatment of unbound tariffs. This paper also gives indications concerning the likely economic impact of this trade round of industrial market access negotiations on African economies. It shows that an ambitious tariff cut reduction formula would provide greater access to developed country markets for African producers. However, this kind of formula has a major drawback for African countries in the sense that it could accelerate the de-industrialization of African countries and limit incentives to diversify their economies.  相似文献

Various promising claims have been made that business can help alleviate poverty, and can do so in ways that add value to the bottom line. This article begins by highlighting that the evidence for such claims is not especially strong, particularly if business is thought of as a development agent, i.e. an organization that consciously and accountably contributes towards pro-poor outcomes. It goes on to ask whether, if we did know more about either the business case or the poverty alleviation case, would this give cause for greater optimism that business could make a significant contribution to development. By exploring the experiences of producers of Fairtrade tea in Kenya, we reveal the complex nature of what constitutes a beneficial outcome for the poor and marginalized, and the gap that can exist between ethical intentions and the experience of their intended beneficiaries. The lessons of these experiences are relevant for Fairtrade and any commercial initiative that seeks to achieve outcomes beneficial and recognizable to the poor, and raise questions about the integration of social and instrumental outcomes that a future generation of ethical entrepreneurship will need to address.  相似文献

Prior research flags the inherent incompatibilities between for-profit and nonprofit partners and cautions that clashing value creation logics and conflicting identities can stall social innovation in cross sector partnerships. Process narratives of successful versus unsuccessful cross sector partnerships paint a more optimistic picture, whereby the frequency, intensity, breadth, and depth of interactions may afford frame alignment despite partners’ divergent value creation approaches. However, little is known about how cross sector partners come to recognize and reconcile their divergent value creation frames in order to co-construct social value. Using longitudinal narratives of four dyads, we show that partners initially contrast their sector-embedded diagnostic frames and then work together to deliberately develop partnership-specific prognostic frames. We extend the literature on framing by developing a four-stage grounded model of frame negotiation, elasticity, plasticity, and fusion which unpacks the relational process of value creation in cross sector partnerships. Our qualitative analyses further show how partners orchestrate multilevel coordination that helps scaffold and calibrate this relational process of frame fusion.  相似文献

Numerous studies have identified constructs such as commitment and brand familiarity as moderators of negativity effects. However, boundary conditions for this moderation have yet to be identified within a retailing context. This study tries to rectify this gap in the literature. This study finds that three factors (commitment, consumer–company identification, and consumer sensitivity to corporate social performance) moderate attitude change toward a retailer following exposure to moderately negative (vs. positive) publicity. However, given extremely negative information, the buffering effects of the moderating factors disappear, and attitude changes are significant for all consumers. © 2009 Wiley Periodicals, Inc.  相似文献

Along with adverse selection, moral hazard is one of the major hurdles that private and public insurance plans must contend with. Moral hazard occurs if risks are endogenous to a producer's behavior and if the insurer is unable to properly monitor the insured. We review the role of moral hazard in the US crop insurance program. We conduct an empirical analysis of one important aspect of the US crop insurance program—prevented planting. This provision provides indemnity payments if conditions are not suitable for planting. The program has been the subject of considerable controversy, especially during 2019, when the rate of claims is expected to be especially high. Because loss adjustors may encounter difficulties in assessing the weather conditions associated with prevented planting claims, the program is susceptible to moral hazard. We consider the extent to which prevented planting claims may be endogenous to prices. We find significant evidence of moral hazard. The likelihood of prevented planting claims increases as the expected market price decreases or as fertilizer costs increase for corn and soybeans in the Prairie Pothole Region and for grain sorghum and cotton in all states.  相似文献

Crop insurance may affect harvested acreage and yield by influencing producers’ behavior such as land allocation and input use. Although specialty crops are a major source of farm income, especially on the U.S. west coast, they have not received as much attention as field crops in previous empirical studies. This paper assesses the effect of moral hazard and adverse selection associated with the federal crop insurance program (FCIP) on the acreage and yield of major specialty crops in California. An econometric method that expands the switching regression model is developed to assess the effect. Results suggest that federal crop insurance can change specialty crop growers’ production responses to climate and soil conditions. The moral hazard effect tends to increase the acreage and yield of the specialty crops, whereas the adverse selection effect tends to have the opposite effect. The overall effect of the FCIP on acreage and yield of specialty crops is found to be moderate.  相似文献

According to the literature on entrepreneurial orientation (EO), proactive firms are more likely to achieve first-mover advantage and higher performance. The neoinstitutionalism, however, suggests that enterprises with more legitimacy will acquire more growth opportunities. Usually, the first mover might face more legitimacy obstacles. To date, there has been little research on how proactive firms cope with legitimacy constraints and achieve firm growth. Integrating the legitimacy perspective and the EO literature, this research examines the roles of ISO certification as a strategy for seeking legitimacy of small and medium-sized enterprises (SMEs) in emerging economies, and the relationship between proactiveness and firm performance. In particular, it hypothesizes that ISO certification has a mediating effect on the relationship between proactiveness and firm growth. We test the hypothesis using a sample of 632 firms collected from a nationwide survey on SMEs conducted by the Chinese SME Association. The results reveal that ISO certification partially mediates the relationship between proactiveness and firm growth, suggesting that proactive firms tend to use legitimation via ISO certification to enhance firm growth. Our paper contributes to the literature by shedding light on the important relationship between seeking legitimacy, entrepreneurial orientation and firm growth in SMEs in an emerging economy.  相似文献
