Unemployment in many continental European countries, particularly among youth, has reached high levels in recent years, and Cahuc and Zylberberg criticize labor market policies that are based on politics rather than economics. They discuss the minimum wage in both the United States and France and show that increasing it, under certain circumstances, can increase employment. They find fault with the idea that work sharing is a cure for unemployment. They consider how to design a system of unemployment insurance that does not destroy the incentive to find work, and examine the effect of government regulation of layoffs. Finally, they analyze the true impact of education and training as remedies for unemployment. Economists today know more about how labor markets work.
