Efficiency Wage Models Of The Labor Market

The contributors explore the reasons why involuntary unemployment happens when supply equals demand.

Known for his seminal work in efficiency-wage theory, Andrew Weiss surveys recent research in the field and presents new results. He shows how wage schedules affect the kinds of workers a firm employs and how well those workers perform on the job. Using straightforward examples, he demonstrates how efficiency-wage theory can explain labor market outcomes and guide government policy. There is a separate section of applications to less developed countries. "Efficiency-wage models represent one of the most important developments in economic theory of recent years. They have, at last, provided integrated explanations both of macroeconomic phenomena, such as unemployment and wage rigidity, and microeconomic phenomena, such as wage dispersion. Weiss--one of the pioneers of efficiency-wage theory--provides here a masterful survey, a lucid and systematic and yet critical account of this rapidly developing branch of economics. This book should be required reading in all courses in macroeconomics."--Joseph Stiglitz, Stanford University "Efficiency Wages should be on the bookshelf of all labor and macroeconomists."--Lawrence H. Summers, Harvard University "A splendid monograph ... most readable... I will put it on my reading list."--Partha Dasgupta, Stanford University Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This chapter has set out in detail the models which are employed below in order to analyse the labour market effects of changes in tax rates and in alterations in the tax structure. The fundamental mechanisms underlying the different approaches have been pointed out. Moreover, vital assumptions have been emphasised. By delineating the models which are used for the subsequent analyses, implicitly statements have also been made about topics or aspects which this study does not cover. For example, all workers and firms are identical ex ante. However, ex-post differences are allowed for, inter alia, if unemploy ment occurs or if some firms have to close down. These restrictions indicate areas of future research insofar as that the findings for homogeneous workers or firms yield an unambiguous proposal for changes in tax rates or the tax structure in order to promote employment. This is because it would be desir able for tax policy to know whether the predicted effects also hold in a world with ex-ante heterogeneity. Furthermore, the product market has not played a role. Therefore, repercussions from labour markets outcomes on product demand - and vice versa - are absent. 55 Moreover, neither the process of capital accumulation, be it physical or human capital, nor substitution pos sibilities between labour and capital in the firms' production function are taken into account. Finally, international competition is not modelled.

Efficiency wage theory suggests that wages (and hence labor markets) may be unresponsive to typical macroeconomic policies that seek to lower real wages, change resource allocation, and reduce open unemployment. Under this theory, firms will react to macroeconomic shocks by altering employment (laying workers off), not wages.

This paper examines the role of the labor market in the transmission process of adjustment policies in developing countries. It begins by reviewing the recent evidence regarding the functioning of these markets. It then studies the implications of wage inertia, nominal contracts, labor market segmentation, and impediments to labor mobility for stabilization policies. The effect of labor market reforms on economic flexibility and the channels through which labor market imperfections alter the effects of structural adjustment measures are discussed next. The last part of the paper identifies a variety of issues that may require further investigation, such as the link between changes in relative wages and the distributional effects of adjustment policies.
