In this paper, we study the determinants of switching from non-renewable natural resource inputs to renewable resource inputs in energy production. We assume that the stocks of both natural resources are stochastic, and that the adoption of renewable resources is costly and irreversible. Our formulation gives raise to an optimal stopping/switching problem that cannot be solved analytically, then we turn to numerical simulations. Our results suggest that the optimal switching time depends not only on the uncertainty parameters, but also on energy demand, costs, and the relative productivity of the resources. 相似文献

This study provides a new framework of analysis of the market and welfare effects of mandatory country‐of‐origin labeling (MCOOL) for fruits and vegetables that accounts for heterogeneous consumer preferences, differences in producer agronomic characteristics, and retailer market power. The market and welfare effects of MCOOL are shown to be case‐specific and dependent on the labeling costs at the farm and retail levels, the strength of consumer preference for domestic products, the market power of retailers, the marketing margin along the supply chain, and the relative costs of imported and domestic products. Simulation results for the U.S. market of fresh apples indicate that domestic producers are the most likely beneficiaries of MCOOL, followed by domestic consumers. Being unable to exercise market power on consumers or suppliers of fresh apples, retailers will lose if the implementation of MCOOL entails fixed costs. Imports of fresh apples decline after MCOOL introduction. 相似文献

We measure and compare agricultural total factor productivity (TFP) growth and its components (efficiency and technical change)
in China and India and test the TFP series for the existence of structural breaks relating the evolution of TFP to policy
milestones. Our results show that agricultural TFP growth accelerates in China after 1979 and in India after 1974, although
China’s agricultural sector clearly outperforms India’s. The main explanation of these differentials is that agricultural
growth in China benefited from more fundamental institutional and policy reforms in agriculture than India. There is some
evidence that the transformation of industry in China was also important for agricultural TFP growth. Manufacture growth absorbed
labor and reduced employment in agriculture, creating incentives for capital investment and technical change that kept output
per worker in agriculture growing at high rates. Fewer changes in agricultural policies and in the dynamics of manufacturing
in India resulted in slower growth in agricultural productivity, despite policy changes that accelerated economic growth in
recent years. 相似文献

This paper provides a new reading of a classical economic relation: the short-run Phillips curve. Our point is that, when dealing with inflation and unemployment, policy-making can be understood as a multicriteria decision-making problem. Hence, we use so-called multiobjective programming in connection with a computable general equilibrium (CGE) model to determine the combinations of policy instruments that provide efficient combinations of inflation and unemployment. This approach results in an alternative version of the Phillips curve labelled as efficient Phillips curve. Our aim is to present an application of CGE models to a new area of research that can be especially useful when addressing policy exercises with real data. We apply our methodological proposal within a particular regional economy, Andalusia, in the south of Spain. This tool can give some keys for policy advice and policy implementation in the fight against unemployment and inflation. 相似文献

An Applied General Equilibrium Model to Assess the Impact of National Tax Changes on a Regional Economy 总被引:1,自引:0,他引:1

This paper presents two versions of an applied general equilibrium model for the regional economy of Andalusia, Spain, that differ in the closure rule adopted to describe the behavior of the public sector. We use the model with to analyze the impact that the reform of the personal income tax (Act 40/98) implemented in Spain as a whole would have had on the Andalusian region in particular. The model is of the neoclassical variety and includes not only the productive sectors of the economy but also the foreign sector and the government, which are usually absent from theoretical general equilibrium models. Both versions of the model are calibrated by using a Social Accounting Matrix of Andalusia for 1995. The analysis shows that the reform is not self-financing, not even partially, despite governmental claims. It also indicates that there is a positive but smaller than anticipated economic stimulus. In welfare terms, we find that the category of Urban Salaried consumers is the one that benefits the most in real income terms. 相似文献

This paper looks at the effect on the exchange rate, in a target zone regime, of changing the width of the band. The main result of the paper is that the exchange rate moves in the same direction as the closest edge of the band does. This effect is stronger, the closer the exchange rate is to the edges of the band. 相似文献
