There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.  相似文献

Green Tax Reform and Competitiveness   总被引:1,自引:1,他引:0  
This paper studies a revenue-neutral green tax reform that substitutes energy for wage taxes in an open economy with unemployment. As long as the labour tax rate exceeds the energy tax rate, such a reform will increase employment, reduce the domestic firms' unit cost of production and hence increase international competitiveness and output of the economy. The driving force behind these results is the technological substitution process that a green tax reform will bring about. The resulting reduction in unemployment is welfare increasing since energy, which the country has to buy at its true national opportunity cost, is replaced with labour, whose price is above its social opportunity cost.  相似文献

Doing practical biodiversity and natural resources management research that is socially and gender sensitive remains a challenge. Most of the relevant literature is primarily at the conceptual level. There are few learning programmes that focus on systematic capacity development for gender and social analysis in applied research in this field. Efforts that systematically document and analyse this kind of capacity development process are also hard to find. This paper summarizes the main research and capacity development achievements and challenges of a novel, Asian-regional initiative that aimed to address these gaps. It is suggested that the success of capacity-building strategies for the integration of social and gender analysis can be enhanced by combining a mix of elements, including a ‘learning by doing’ approach, participatory (action) research methodologies, a diverse group of participants, regular peer review, flexible networking and strong personal and organizational commitment. These kinds of strategies will require a long(er) time horizon and sufficient resources.  相似文献

This paper shows that outsourcing of parts of the workforce in unionized firms leads to wage moderation both in the case of strategic and flexible outsourcing. As long as the share of the outsourced workforce is not too large, this wage‐moderation effect on domestic employment outweighs the direct substitution effect so that domestic employment increases in unionized firms as outsourcing costs fall. With respect to the impact of labor tax reform changes in the wage tax rate, the tax exemption and the unemployment benefit payments affect domestic wage setting in the same way as in the absence of outsourcing. Furthermore, increasing the degree of tax progression by keeping the relative tax burden per worker constant continues to be good for employment. However, except for low outsourcing activities, the impact of these policy measures will become smaller as outsourcing costs fall.  相似文献

There seems little chance of achieving many social objectives, given that the ways in which they are being pursued fail to harness self-interest. A way forward is to create a new financial instrument - Social Policy Bonds - which would be auctioned by government. The bonds would be tradable and would be redeemed only when a specified social objective had been achieved.  相似文献

There is widespread agreement on the ability of ecological tax reforms to improve the environmental quality. This paper, however, points out that a negative marginal impact on the environment cannot be ruled out for revenue-neutral ecological tax reforms in both first-best and second-best frameworks. Therefore, sufficient conditions are derived which ensure the improvement of the environmental quality.  相似文献

PARTIAL HEDGING IN A STOCHASTIC VOLATILITY ENVIRONMENT   总被引:1,自引:0,他引:1  
We consider the problem of partial hedging of derivative risk in a stochastic volatility environment. It is related to state-dependent utility maximization problems in classical economics. We derive the dual problem from the Legendre transform of the associated Bellman equation and interpret the optimal strategy as the perfect hedging strategy for a modified claim. Under the assumption that volatility is fast mean-reverting and using a singular perturbation analysis, we derive approximate value functions and strategies that are easy to implement and study. The analysis identifies the usual mean historical volatility and the harmonically averaged long-run volatility as important statistics for such optimization problems without further specification of a stochastic volatility model. The approximation can be improved by specifying a model and can be calibrated for the leverage effect from the implied volatility skew. We study the effectiveness of these strategies using simulated stock paths.  相似文献
