Transportation in disaster response operations

Disasters are extraordinary situations that require significant logistical deployment to transport equipment and humanitarian goods in order to help and provide relief to victims. An efficient response helps to reduce the social, economic and environmental impacts. In this paper, we define and formulate a practical transportation problem often encountered by crisis managers in emergency situations. Since optimal solutions to such a formulation may be achieved only for very small-size instances, we developed an efficient genetic algorithm to deal with realistic situations. This algorithm produces near optimal solutions in relatively short computation times and is fast enough to be used interactively in a decision-support system, providing high-quality transportation plans to emergency managers.     

Financial Turmoil, Failed Bank Acquisitions, and Bank Business Lending Behavior

This paper utilizes bank Call Report and FDIC receivership data from 1987 to 1991 to examine the impact of a failed bank acquisition on the growth rate of commercial and industrial (C&I) lending at the acquiring institutions. Using a two-stage least squares model with fixed effects, we find that banks acquiring a failed bank's assets experience a significant decline in both the growth rate of C&I lending and their capital asset ratios in the period of the acquisition. The results support anecdotal evidence that failed-bank borrowers may experience difficulties in accessing credit once their bank fails and underscores the importance of bank-borrower relationships in C&I lending. Finally, the paper provides an alternative explanation for banks' stagnant or declining business lending activity during this period of financial turmoil.     

Connectivity in the Commercial Internet

We study the 'backbone market' in the Internet. After discussing the structure of the Internet, we use an extension of the Katz-Shapiro network model to analyze the strategies that would be used by dominant backbone. We show that a larger backbone prefers a lower quality interconnection than the smaller one. We then analyze a 'targeted degradation' strategy where the larger backbone lowers the quality of interconnection to its smaller rivals in turn. Finally, we show that the qualitative results are robust to the possibility of 'multihoming' by clients.     

LABOUR PRODUCTIVITY COMPARISON BETWEEN CZECHOSLOVAKIA AND FRANCE

This paper reports on the results of the bilateral study of the comparison of levels of labor productivity in industry between Czechoslovakia and France in 28 branches of industry. Because of the importance of common studies of the questions of productivity of labor and its international comparison, the Economic Commission for Europe of the U.N. decided several years ago to introduce a concrete programme of work in this sphere. This study was made jointly by Czechoslovakia and France. The present paper reports on the first stage of the study, giving results based on physical unit methods. The second stage of the work includes comparisons for branches of industry not covered in this paper, on the basis of value indicator methods; detailed results will be published in respective U.N. series to the end of 1969 (Series Conf. Eur. Stats.).     

DEA APPLIED TO A GAUTENG SAMPLE OF PUBLIC HOSPITALS1

The research presented in this paper provides an analysis of the delivery of a few health care services by the public sector in Gauteng, South Africa. The data for the study was especially difficult to collect, suggesting the need for hospital level data information systems, as well as staff who are trained to analyze the information collected. The empirical results from the analysis suggest that services provided by small‐scale medical facilities waste fewer resources, while medical centres offering more technical services, such as surgeries, also appear to deliver medical services more efficiently.     

The EMU’s Twisted Foundations: How to Use and Misuse Economic Theory

The creation of common European currency is the most ambitious institutional project of the European Union for decades. The idea of launching this kind of currency has merits. However, the implementation of this idea has already led to very negative consequences, as political considerations had priority over economic ones. The article shows how theoretical approaches to common currencies have been evolving since 1960s and why misuse of economic theory provokes inevitable collapse of the European monetary union.     

Information shocks and the empirical evaluation of training programs during unemployment spells

We study the role of notifications in the evaluation of training programs for unemployed workers. Using a unique administrative data set containing the dates when information is exchanged between job seekers and caseworkers, we address three questions: Do information shocks, such as notification of future training, have an effect on unemployment duration? What is the joint effect of notification and training programs on unemployment? Can ignoring information shocks lead to a large bias in the estimation of the effect of training programs? We discuss these issues through the lens of a job search model and then conduct an empirical analysis following a “random effects” approach to deal with selectivity. We find that notification has a strong positive effect on the training probability but a negative one on the probability of leaving unemployment. This “attraction” effect highlights the importance of accounting for notifications in the evaluation of active labor market policies.     

On an absolute measure of distributional change

This paper tries to combine Kolm's ideas on the measurement of inequality with the recent work of Cowell on the generalized entropy families of income distribution and change indices. A ‘leftist’ measure of income distributional change is proposed, which is invariant to equal absolute changes in all incomes and which has other interesting properties.     

The immigration issue

This article outlines the historical development of migration. It then discusses, with reference to two extreme scenarios, the future economic, religious and cultural effects of continued immigration.     

Convergence - the Maastricht approach to economic and monetary union (EMU) in Europe

This article reviews the concept of convergence in the Maastricht Treaty and notes that, while in certain areas the convergence objectives are quite ambitious, in other areas the objectives for the transition period are surprisingly limited. By end-1992, much progress had already been achieved on convergence in a majority of EC countries (and countries applying for membership). Thus, despite the wave of pessimism that followed the recent exchange market crisis, it is still quite possible that a majority of EC members could qualify for monetary union by 1997. However, this would require further significant adjustment in many cases in the fiscal area. Based on the Multimod Model used at the Fund, the deflationary effect of this fiscal consolidation would be small and short lived.
