Temporary job contracts account for a substantial proportion of the workforce in countries such as France and Spain, but they can result in high job turnover and instability. This column assesses the impact of government policies that impose taxes on temporary contracts to induce employers to lengthen job durations. Such policies a negative impact on the labour market, reducing the mean duration of jobs and decreasing job creation. The introduction of open-ended contracts with no termination cost for separations occurring at short tenure may be more effective.

The dual labour markets of Southern Europe and France create a ‘revolving door’ through which many workers – especially youths – rotate between dead-end jobs and unemployment. The problem lies in the difference between the costs of firing workers on permanent versus temporary contracts. This column proposes a framework for evaluating what the optimal single contract should look like taking account of transitional issues and political economy constraints.

It revolutionalised the way economists think about optimal institutions and regulation when governments don't “know it all.” It has had a major impact on current policy-making and will continue to do so in the future.
