Normal comparisons of industrial structures in East and West Germany

Summary Direct comparisons of East and West German industrial structures fail to reveal significant differences. On the other hand, comparisons of actual East and West German industrial structures with their normal counterparts indicate important structural differences, especially in the light and heavy manufactures output mix. It is argued that these differences reflect institutional differences (free enterprise capitalism and centrally planned socialism) insofar as they are not explained by differences in trade utilization.

Does Ethnicity Matter for Access to Childhoodand Adolescent Health Capital in China? Evidence from the Wage-Height Relationship in the 2006 China Health and Nutrition Survey

This paper considers whether ethnicity conditions the return and access to health capital in China. Given that the wage-height relationship reflects the labor market earnings returns to childhood and adolescent health capital, differences in the labor market returns to height by ethnicity reflect ethnic differences in access to health capital during childhood and adolescence. We theoretically motivate the role of height in earnings by providing a Bioeconomic rationale for stature and height determining individual wages, and estimate height-augmented Mincerian earnings functions with data from the 2006 China Health and Nutrition Survey. Our results show that when the effects of unobserved genetic influences on adult height are accounted for, the labor market return on height is higher for Chinese ethnics. This suggests that in China there are ethnic disparities in access to the inputs that produce childhood and adolescent health capital.     

Unemployment duration and unemployment insurance: a comparative analysis based on Scandinavian micro data

Based on pooled register data from Norway and Sweden, we findthat differences in unemployment duration patterns reflect dissimilaritiesin unemployment insurance (UI) systems in a way that convincinglyestablishes the link between economic incentives and job searchbehaviour. Specifically, UI benefits are relatively more generousfor low-income workers in Sweden than in Norway, leading torelatively longer unemployment spells for low-income workersin Sweden. Based on the between-countries variation in replacementratios, we find that the elasticity of the outflow rate frominsured unemployment with respect to the replacement ratio isapproximately one in Norway and 0.5 in Sweden.     

Rational choice models of crimes by youth

This article presents research findings from three analyses of criminal activity among youth. The data set used in all three is the National Longitudinal Survey of Young Americans, a data set that is particularly appropriate for this type of analysis. The work examined the relationship between criminal behavior and family and moral influences; the impact of legitimate labor market activity on participation in crime; and the effect of school enrollment on criminal activity. The findings confirm the hypothesis that black and white differences in criminal participation partially reflect differences in economic opportunity.     

Abstracts/Résumés

This paper examines whether credit analysts utilize the information contained in the difference between book and taxable income in analyzing a firm’s credit risk. Increased book–tax differences may be informative for credit rating agencies as they may signal decreased earnings quality or changes in the firm’s off–balance sheet financing. Results suggest a significant negative association between positive changes in book–tax differences and ratings changes. This evidence is consistent with large positive changes in book–tax differences signaling decreased earnings quality and/or increased off–balance sheet financing. We also find that large negative changes in book–tax differences result in less favorable rating changes, consistent with these changes signaling decreased earnings quality. In additional analyses, we find that the association between changes in book–tax differences and rating changes is attenuated for high–tax‐planning firms (e.g., where book–tax differences more likely reflect tax planning than decreased earnings quality).     

The Environmental Kuznets Curve Hypothesis and Air Pollution in Finland

Abstract

The historiography of mercantilism has been described as a series of disconnected still pictures which reflect the shifting viewpoints of economic thought.¹ However, historians have favoured different concepts of mercantilism not only in response to the shifts of economic science but also because they have held, explicitly or implicitly, different opinions on the problem of how economic ideas are formed and of the role they have played in historical development. The following reexamination of some of those ‘stills’ concentrate on such differences.²
