Since the mid-1970s Spain has suffered from persistently high unemployment, as it has occurred in other parts of Europe. Although during the last few years the unemployment level has declined, there are still enormous disparities in the unemployment rate across groups, skills and regions. This thesis attempts to shed some light on the mechanisms of unemployment persistence and skill and regional mismatch in Spain. Chapter 1 provides a first introductory analysis of Spanish data. The chapter emphasises the importance of skill and regional mismatch, which may have contributed about fifty percent to the observed increase in total unemployment over the last twenty years. The chapter also studies the cyclical pattern in the Spanish unemployment, which is a very important aspect in view of its magnitude. The following three chapters are devoted to the evaluation of different mechanisms that may have been at work. In all three chapters, the analysis relies on the specification, calibration and simulation of dynamic general equilibrium models with matching on the labour market. Chapter 2 focuses on cyclical fluctuations, with particular emphasis on the role of reallocation shocks. Chapter 3 focuses on « skill mismatch »; more precisely the chapter investigates to what extent unemployment rate disparities across skill groups can be explained in terms of a « ladder effect ». Chapter 4 focuses on regional disparities. A model is built to investigate the possible determinants of regional disparities and the role of labour mobility.

Spain has the most serious and persistent unemployment problem in Europe, with an unemployment rate that reached 24.6 percent in early 1994. This paper explores the characteristics of this unemployment problem, its causes, and provides a brief discussion of recent labor market reform measures and their likely Impact. A demographic shift in recent years has produced a large rise in female labor force participation and a decrease in agricultural jobs to which the economy has been unable to adjust. The effects of generous unemployment benefits and the large underground economy may explain 6–12 percentage points of the resulting unemployment, but the remainder must be explained by failures and rigidities in the labor market. The paper presents econometric evidence that unemployment displays hysteresis, and that wages are not responsive to changes in the unemployment rate. This evidence supports the claim that insider-outsider factors and rigidities in the legal structure of the labor market are responsible for much of the high unemployment rate. Recent reforms have improved the functioning of the labor market, but they are unlikely to be sufficient to reduce unemployment to single digit rates without further action.
