The Last Word on the Wage Curve? 总被引:2,自引:0,他引:2
Abstract. Since 1990, there has been extensive international research on the responsiveness of wages of individuals to changing local labour market conditions. For many countries, an inverse relationship between wages and local unemployment rates has been found. In their book, The Wage Curve , Blanchflower and Oswald argued that the unemployment elasticity of pay is around −0.1 in most countries. In a 1995 literature survey, Card referred to this striking empirical regularity as being close to an 'empirical law of economics'. Nonetheless, reported elasticities do vary, even excluding outliers, between about −0.5 and +0.1. There is also considerable heterogeneity among wage curve studies in terms of data and model specification. This paper carries out meta‐analytic techniques on a sample of 208 elasticities derived from the literature to uncover the reasons for the differences in empirical results across studies. Several causes of variation are identified. There is also clear evidence of downward publication bias. In addition, many reported t ‐statistics are biased upwards due to the use of aggregate unemployment rates. A maximum likelihood method and a trimming procedure are used to correct for these biases. Both methods give similar results for our sample. An unbiased estimate of the wage curve elasticity at the means of study characteristics is about −0.07. 相似文献

Summary. We prove that, for finitely many demand observations, the Strong Axiom of Revealed Preference tests not only the existence of a strictly concave, strictly monotone and continuous utility generator, but also one that generates an infinitely differentiable demand function. Our results extend those of previous related results (Matzkin and Richter, 1991; Chiappori and Rochet, 1987), yielding differentiable demand functions but without requiring differentiable utility functions.Received: 1 November 2001, Revised: 5 February 2004, JEL Classification Numbers:

J. Peter Neary 《Environmental and Resource Economics》2006,33(1):95-118
I review and extend three approaches to trade and environmental policies: competitive general equilibrium, oligopoly and monopolistic
competition. The first two have surprisingly similar implications: deviations from first-best rules are justified only by
constraints on policy choice (which motivates what I call a “single dividend” approach to environmental policy), and taxes
and emissions standards differ in ways which reflect the Le Chatelier principle. I also show how environmental taxes may lead
to a catastrophic relocation of industry in the presence of agglomeration effects, although not necessarily if there is a
continuum of industries which differ in pollution intensity.

This paper introduces the idea of “robust political economy.” In the context of political economic systems, “robustness” refers
to a political economic arrangement's ability to produce social welfare-enhancing outcomes in the face of deviations from
ideal assumptions about individuals' motivations and information. Since standard assumptions about complete and perfect information,
instantaneous market adjustment, perfect agent rationality, political actor benevolence, etc., rarely, if ever actually hold,
a realistic picture and accurate assessment of the desirability of alternative political economic systems requires an analysis
of alternative systems' robustness. The Mises-Hayek critique of socialism forms the foundation for investigations of robustness
that relax ideal informational assumptions. The Buchanan-Tullock public choice approach complements this foundation in forming
the basis for investigations of robustness that relax ideal motivational assumptions.

This study analyses the effect of trade and migration on wages and labour marketmobility. We estimate wage growth equations and a multinomial logit mobilityequation on an individual data set ranging from 1991 to 1994. We find substantialdifferences in the reactions of white and blue-collar workers wages and mobilityto trade and migration. In Austria exports have a positive and imports a negativeimpact on wage growth only for blue-collar workers. Migrants also reduce onlyblue-collar workers wage growth. Our results indicate that higher imports and aninflow of migrants reduce sectoral mobility of all types workers. The risk of beingout of work by contrast is increased by migration and imports only for blue-collarworkers, but reduced by exports for all types of workers. In general our results suggestenlargement of the EU would have only small effects on the Austrian labour market. 相似文献

Dynamic equilibria with unemployment due to undernourishment 总被引:1,自引:0,他引:1
Summary We provide characterization and stability results for the stationary equilibria of a competitive infinite-horizon model that incorporates the nutritional requirements of physical labor. We find that for many aggregate land stocks, there is a large continuum of stationary equilibrium unemployment rates. Since unemployment can be seen to stem from inequality in the initial distribution of land ownership, we suggest that certain land reforms can reduce unemployment.Many of our results were developed while Streufert visited the Indian Statistical Institute. Ray is grateful for financial support from the Warshow Endowment of Cornell University, and Streufert thanks the Institute for Research on Poverty and the Graduate School, both at the University of Wisconsin-Madison. We are also thankful for the useful comments of an editor, a referee, and seminar participants at Wisconsin, Yale, the Federal Reserve Bank of Minneapolis, and the Midwest Mathematical Economics Conference. 相似文献
