Port workers services have been usually heavily regulated and reserved exclusively for a special kind of workers, dockworkers,
which seems to have been the cause of serious inefficiencies worldwide. During the eighties, law reforms have been introduced
to solve this problem. In this paper we analyze and decompose efficiency in cargo handling operations in 19 Spanish ports
from 1990 to 1998. The method chosen is that of the parametric estimation of both allocative and technical inefficiency using
panel data and a quadratic cost function. Results show that although inefficiency has decreased overall, there has been over
utilization of labor regarding capital, and technical inefficiency. This supports the need of further consideration of other
aspects including competition.

This paper presents estimators of distributional impacts of interventions when selection to the program is based on observable characteristics. Distributional impacts are calculated as differences in inequality measures of the marginal distributions of potential outcomes of receiving and not receiving the treatment. The estimation procedure involves a first non‐parametric estimation of the propensity score. In the second step weighted versions of inequality measures are computed using weights based on the estimated propensity score. Consistency, semi‐parametric efficiency and validity of inference based on the percentile bootstrap are shown for the estimators. Results from Monte Carlo exercises show its good performance in small samples. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

The geographical allocation of Spanish aid has been little studied, despite its unusual concentration on middle-income countries. This paper develops a theoretical model in which aid allocation depends on a combination of recipient needs, donor interests and performance criteria, and estimates it econometrically for Spain. The results show that the allocation of Spanish aid has been influenced both by Spain's own foreign policy interests and by recipient needs for poverty reduction and development (although not by the quality of recipient governance or recipient absorptive capacity). Former Spanish colonies received a disproportionate share of Spain's aid (as is true mutatis mutandis for other European countries), but aid is allocated among them with greater regard to recipient need than is Spain's aid to other developing countries. 相似文献

This paper addresses the stability of a multimarket competitive equilibrium. The dependence of stability on the choice of the numeraire is clarified. The traditional tâtonnement pricing is revised in order to satisfy some basic features of economic behaviour. Well‐known conditions for local stability are proved to be insufficient if a market for credit is introduced alongside the markets of dated commodities. Stability depends not only on the slopes of the demand and supply curves, but also on equilibrium prices. This result emerges without the occurrence of capital perversities, such as reswitching and reverse capital deepening. 相似文献

Three sets of arguments are presented, which are for and against the development of a European Community (EC) cultural policy and also seem to apply to the development of a European media policy. These arguments cluster around the ‘mass’ character of the media, the relationship between economy and culture and the loss of national identities. In a concluding paragraph the arguments will be summarized by presenting two different, and more or less opposite, approaches to the formulation of an EC media policy. 相似文献

This article studies the sensitivity of the US stock market to nominal and real interest rates and inflation during the 2003–2013 period using quantile regression (QR). The empirical results show that the stock market has a significant sensitivity to changes in interest rates and inflation and finds differences across sectors and over time. Moreover, the effect of changes in both interest rates and inflation tends to be more pronounced during extreme market conditions, thus distinguishing expansion periods from recession periods. 相似文献

Modeling exchange rate passthrough after large devaluations 总被引:1,自引:0,他引:1
Large devaluations are generally associated with large declines in real exchange rates. We develop a model which embodies two complementary forces that account for the large declines in the real exchange rate that occur in the aftermath of large devaluations. The first force is sticky nontradable-goods prices. The second force is the impact of real shocks that often accompany large devaluations. We argue that sticky nontradable goods prices generally play an important role in explaining post-devaluation movements in real exchange rates. However, real shocks can sometimes be primary drivers of real exchange-rate movements. 相似文献

Actually, the country's development aims to achieve higher levels of productivity, so it had to adapt to international standards. This has served to ease the hiring of both operational and managerial controls, giving emphasis on training and allowing the pairing boss-worker to take the productivity like benchmark. The labor reform allows companies to make changes with their workers; such changes must be reflected in lower costs for businesses, by labor input and increased competitiveness, however, two years ago this guideline was implanted and society asks if the results are congruent, because Mexican society is undergoing economics problems issue as well as a deficit in generating jobs. Therefore, analyzing whether modifications made to the federal labor law (FLL) are designed to optimize safety of workers and enterprises in which they work is the subject of this research. The corresponding analysis was performed using the deductive method. 相似文献
