The paper presents a stochastic insider-outsider model that accounts for the following stylized facts: (1) unemployment rates display a high degree of serial correlation, or `persistence'; (2) the average rate of unemployment has been higher in the United States than in Europe over the 1950s and...

We present a theory of involuntary unemployment which explains why the unemployed workers ("outsiders") are unable or unwilling to find jobs even though they are prepared to work for less than the prevailing wages of incumbent workers ("insiders"). The outsiders do not underbid the insiders...

The paper suggests alternatives to the Harris-Todaro theory to explain unemployment in segmented labour markets. We focus on a labour market with a perfectly competitive secondary sector and an imperfectly competitive primary sector, the latter combining salient features of the efficiency-wage,...

The paper analyzes how the influence of labour unions over wage contracts may make an economy less "resilient". Loss of resilience is depicted in two conceptually independent ways: (i) the tendency of exogenous variations in unemployment to become perpetuated and (ii) the possibility that such...

This paper compares two theories of involuntary unemployment: the efficiency-wage theory and the insider-outsider theory. We indicate that one of the central problems in providing microfoundations for the existence of involuntary unemployment is to explain why there is no underbidding, and we...

The paper examines the implications of an important aspect of the ongoing reorganization of work – the move from occupational specialization towards multi-tasking – for centralized wage bargaining. The analysis shows how, on account of this reorganization, centralized bargaining becomes...
