Government permission is required to dismiss or lay off even a single worker in India and Zimbabwe. Dynamic labor demand equations, derived from a CES cost minimization model, are estimated for 64 manufacturing industries in these two countries. The data reveal a substantial reduction in demand for workers but no slowing in adjustment of number of employees following enactment of the labor laws. In India, no comparable reduction in labor demand occurred in small scale plants uncovered by the job security regulations. Among larger Indian plants, the drop in labor demand is estimated to be largest in industries where: coverage of the legislation is more extensive, private ownership dominates, and there are fewer union members. 相似文献

This paper models the volatility of national stock market returns of the G-7 countries using ARCH and GARCH modeling techniques. Then, via the use of vector autoregression analysis, the international transmission of volatility among the countries is explored for the period between April 1973 and July 1990. Variance decompositions are calculated in order to quantify the impacts of volatility shocks in one market on the others. Impulse response functions are used to inspect the dynamic responses of domestic and foreign volatility shocks. Results indicate that volatility transmission among the G-7 countries is the norm in the post-Bretton Woods era. Further, we find that volatility shocks are generally absorbed within six to nine months. 相似文献

Biologists and conservation advocates have expressed grave concern over perceived threats to biological diversity. ``Biodiversity prospecting' – the search among naturally occurring organisms for new products of agricultural, industrial, and, particularly, pharmaceutical value – has been advanced as both a mechanism and a motive for conserving biological diversity. Economists and others have attempted to estimate the value of biodiversity for use in new pharmaceutical project research. In this paper we apply a new approach to estimating values: we employ two models of competition among differentiated products. Each model confirms previous findings that the value to private researchers of the ``marginal species' is likely to be small. The models can have very different implications with respect to social values, however. These findings underscore the need for a better understanding of the true meaning of diversity.Resources for the Future 相似文献

Using a difference-in-differences estimation framework and state-level data, we investigate the potential role of HIV/AIDS in contributing to declining abortion utilization in the United States. Our results suggest that the perceived risk of HIV contraction negatively affected unwanted pregnancies. Specifically, a 10% increase in HIV incidence is associated with 0.34–1.1% fewer abortions per live births, an effect that can account for at least one-tenth of the sharp decline in abortions observed from the early 1980s to mid-1990s. 相似文献

Modern irrigation technologies have been suggested as a means of conserving scarce water and reducing environmental pollution caused by irrigated agriculture. This paper applies an economic model of technology selection that provides a general framework to analyzing adoption of irrigation technologies under various environmental conditions. Data from the San Joaquin Valley of California is used to verify the theoretical relationships. Results suggest key variables to be considered by policy makers concerned with adoption of modern irrigation technologies. Among these variables are crop prices, water technology costs, farm organization characteristics, and the environmental conditions of the farm or the field. Policy implications were discussed and analyzed.This research was conducted while the first author was a visiting scholar with the Dept. of Agricultural Economics, University of California, Davis, and USDA-ERS, USA. 相似文献

This paper begins with a tax and a specially organized commission proposed by John R. Commons. Commons made his proposal because high tariffs were not benefiting workers. The paper contends that his proposal also applies to a current problem - the failure of trade agreements to improve working conditions. The paper bases its argument on data, standard economic reasoning, and Commons’ approach in “constructive research” to wage transactions, public purpose, limiting factors, and power imbalances.The paper argues that Commons’ proposal could improve the evolution of American labor law and that it could ameliorate power imbalances created by laws that give corporations and trade associations a bargaining advantage over nations and organizations such as the International Labor Organization (ILO). It concludes that economic discourse could benefit from consideration of the belief behind Commons’ proposal - that costs of production passed on to consumers should include the cost of good working conditions. 相似文献
