"Microeconomic simulations are performed to determine the impact of liberalized commodity trade on Mexican immigrant supply to the United States. The results suggest that a removal of trade barriers will reduce migration flows, but that the reduction will be fairly modest. Specifically, if both countries move from the levels of protection characteristic of the mid-1960s to completely free trade, the ratio of real U.S.-Mexican wages falls by roughly 18 percent. Using an upper bound for the range of empirical estimates of the wage elasticity of immigrant supply, this implies a maximum reduction in migration flows of 35 percent. A unilateral elimination of trade barriers by the United States reduces Mexican immigrant supply by a maximum of 14 percent." 相似文献

The challenge for the UN and for all publicly funded institutions that distribute surpluses for international needs is nothing less than to devise new global mechanisms for the collection and distribution of the surplus generated in a global economy. A minimalist interpretation of when individual governments can and cannot provide public goods has exercised strong influences on perceptions as to what is appropriate at international levels and with regard to the financing of international institutions. There is a strong consensus on an important range of international social goods. Three kinds of financing alternatives should be accorded priority in policy research—charges for the use of the global commons, monetary measures, and international taxation. 相似文献

The objective of the paper is to explore potential changes in trade induced by a liberalization scenario when taking into account persistence in trading partners. Our approach is based on the development of a gravity model that takes into account the dynamics at the extensive margin of trade as well as the persistence effect of the intensity of trade. Our empirical contribution is on the egg sector, where the persistence in trading partners is acute. Our results indicate that the use of static models underestimate imports of table eggs by more than 50% in Canada, when compared with the use of panel dynamic specification. The dynamic specification helps explain why trade liberalizations often increase trade creation between countries that had already been trading partners, while new trading partnerships remain scarce following trade liberalization. Our results also confirm the importance of sunk cost and their negative impact on the probability of export market participation for developing countries. Those results raise questions regarding the benefit of trade liberalization for developing countries, in terms of accessing new market, if they do not benefit from special treatments. 相似文献

Relatively little attention has been paid in the economics literature to the effects of meteorological conditions on milk production. Meteorological variables can be expected to affect milk production through their impact on the productivity of cows and the production of foodstuff. Rather than including meteorological variables as inputs in the milk production process, we propose a production function where these variables affect the productivity of cows and the production of forage, thereby indirectly affecting milk production. Using production and meteorological data from the Spanish region of Asturias corresponding to 383 dairy farms observed during a six‐year period from 2006 to 2011, the results from our estimated production function show that meteorological variables have a significant impact on milk production. We find that milk production is higher under warm weather conditions due to improvements in forage production. 相似文献
