Enforcement of employment security regulations, on-the-job search and unemployment duration

Contrary to the popular wisdom, 'sclerotic' European labour markets are cha racterised by relatively large job turnover rates, A model is developed whi ch - unlike standard theories of job matching with on-the-job search - can account for the coexistence of strict employment security regulations, sign ificant job-to-job shifts and high long-term unemployment rates in these co untries. This is because: (i) employment security regulations can only be e nforced by increasing the number of workers on 'short-term jobs', and (ii) the latter compete for jobs with unemployed jobseekers. Evidence is present ed showing that job-finding probabilities of the unemployed are decreasing in the incidence of temporary employment, in line with the predictions of t he model.
