In his Ph. D. thesis, Rudiger Wapler analyses the causes of the persistently high unemployment rates especially in continental Europe. Particular emphasis is placed on imperfect labour and product markets on the one hand, and on the numerous links between unemployment, innovations and growth on the other. Hence, Rudiger Wapler provides an important contribution towards a better understanding of both the development of labour markets as well as the dynamics of growth. To aid readers with only little prior knowledge of labour markets, the book presents the most common theories of unemployment: (1) trade-union models in which union bargaining power leads to wages above their market-clearing level, (2) efficiency-wage models in which employers voluntarily pay higher wages in order to motivate or discipline their workers or to reduce the job turnover rate, as well as (3) matching models in which unemployment is caused by the continuous turnover of jobs and workers. In addition, emphasis is placed on the fact that labour needs to be treated as heterogeneous, a fact often neg lected in the literature. Subsequently, these labour-market foundations are integrated with modern theories of innovations and growth, making the ap proach much more relevant and plausible. Without doubt, the generalisations of the models performed by Rudiger Wapler show that there are limits to such formal analysis. Due to the increasing number of interdependencies, it is doubtful whether even more complex models provide additional (usable) insights.

During much of the 1980s, US wage growth has been unexpectedly slow in the face of relatively low unemployment rates and high capacity utilization rates. This collection of papers resulting from the Wage Structure Conference held by the Federal Research Bank of Cleveland, November 1989, helps explain labour market behaviour in that period. The contributors - academic and research economists in labour economics - provide a comprehensive assessment of the current state of the wage-setting process in the US labour market.

Economic research monograph on the relationship between education, unemployment and economic growth in the USA - presents an overview of the American labour force force, covers the geographic distribution and population distribution of unemployment, labour market factors, some vocational training programmes to alleviate unemployment among low income groups, etc., and includes short term projections for 1980.

Dissatisfied with the explanations of the business cycle provided by the Keynesian, monetarist, New Keynesian, and real business cycle schools, Edmund Phelps has developed from various existing strands-some modern and some classical--a radically different theory to account for the long periods of unemployment that have dogged the economies of the United States and Western Europe since the early 1970s. Phelps sees secular shifts and long swings of the unemployment rate as structural in nature. That is, they are typically the result of movements in the natural rate of unemployment (to which the equilibrium path is always tending) rather than of long-persisting deviations around a natural rate itself impervious to changing structure. What has been lacking is a "structuralist" theory of how the natural rate is disturbed by real demand and supply shocks, foreign and domestic, and the adjustments they set in motion. To study the determination of the natural rate path, Phelps constructs three stylized general equilibrium models, each one built around a distinct kind of asset in which firms invest and which is important for the hiring decision. An element of these models is the modern economics of the labor market whereby firms, in seeking to dampen their employees' propensities to quit and shirk, drive wages above market-clearing levels-the phenomenon of the "incentive wage"--and so generate involuntary unemployment in labor-market equilibrium. Another element is the capital market, where interest rates are disturbed by demand and supply shocks such as shifts in profitability, thrift, productivity, and the rate of technical progress and population increase. A general-equilibrium analysis shows how various real shocks, operating through interest rates upon the demand for employees and through the propensity to quit and shirk upon the incentive wage, act upon the natural rate (and thus equilibrium path). In an econometric and historical section, the new theory of economic activity is submitted to certain empirical tests against global postwar data. In the final section the author draws from the theory some suggestions for government policy measures that would best serve to combat structural slumps.
