Search costs and efficiency: Do unemployed workers search enough?

Many labor market policies affect the marginal benefits and costs of job search. The impact and desirability of such policies depend on the distribution of search costs. In this paper, we provide an equilibrium framework for identifying the distribution of search costs and we apply it to the Dutch labor market. In our model, the wage distribution, job search intensities, and firm entry are simultaneously determined in market equilibrium. Given the distribution of search intensities (which we directly observe), we calibrate the search cost distribution and the flow value of non-market time; these values are then used to derive the socially optimal firm entry rates and distribution of job search intensities. From a social point of view, some unemployed workers search too little due to a hold-up problem, while other unemployed workers search too much due to coordination frictions and rent-seeking behavior. Our results indicate that jointly increasing unemployment benefits and the sanctions for unemployed workers who do not search at all can be welfare-improving.     

Innovation diffusion,employment and wage policy

Contrary to most writings in the field of evolutionary economics which have a strong microeconomic flavor, here amacroeconomic evolutionary model will be presented in order to deal with themacroeconomic employment effect of technical change where there is just one old and one new technology. Several authors who favour an evolutionary approach to the theory of technical change share an optimistic view with respect to the macroeconomic employment effect of technical change. In the paper we are dealing with the question of whether this optimistic view is a necessary result of an evolutionary approach to technical change or rather of some other characteristic of the models used. It is shown that the evolutionary approach to technical change is not inherently optimistic or pessimistic with respect to the employment effects. Rather it is the labour market behaviour that will decide, whether the employment effects of technical change are positive, negligible or even negative.     

The Swedish third way: an assessment of the performance and validity of the Rehn-Meidner model

This paper analyses the functioning of the Rehn–Meidnermodel in Sweden and the validity of the model's underlying theory.Both sceptics and friends of ‘the Swedish model’have exaggerated the effects of active labour market policyand solidarity wage policy on employment, inflation and growth.However, these policies have contributed to the reduction ofhysteresis effects and wage differentials in Sweden. Furthermore,Swedish experiences confirm the Rehn–Meidner view thatpositive demand shocks and expansionary macroeconomic policiesmake it difficult to combine full employment with price stability,economic growth and equity even if central wage negotiationsare coordinated and trade unions willingly accept wage restraint.
