This paper offers an explanation for why policy makers stick to inefficient policy decisions. I argue that repealing a policy is a bad signal to voters about the policy maker's competence if voters do not have complete knowledge about the effects of implemented policies. I derive the optimal...

The continuing deterioration of the position of low skilled workers in the beginning of the 90's in essentially all industrialized countries is one of the most debated issues in both labor and macro-economics. In this paper a matching model with low and high skilled workers and simple and...

Contemporary financial stochastic programs typically involve a trade-offbetween return and (downside)-risk. Using stochastic programming we characterize analytically (rather than numerically) the optimal decisions that follow from characteristic single-stage and multi-stage versions of such...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) "Index for industry concentration". This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

In this paper we present an exact maximum likelihood treatment forthe estimation of a Stochastic Volatility in Mean(SVM) model based on Monte Carlo simulation methods. The SVM modelincorporates the unobserved volatility as anexplanatory variable in the mean equation. The same extension...

In this paper we compare the predictive abilility of Stochastic Volatility (SV)models to that of volatility forecasts implied by option prices. We develop anSV model with implied volatility as an exogeneous var able in the varianceequation which facilitates the use of statistical tests for...

Trade unions tend to reduce the dispersion of wages among their members. Skilled workers may therefore have an incentive to separate from an encompassing union and organize into a separate craft union. In this paper, we examine a theoretical model to gain insight into the determinants of the...

Convergence in gross domestic product series of five European countriesis empirically identified using multivariate time series models that arebased on unobserved components with dynamic converging properties.We define convergence in terms of a decrease in dispersion over timeand model this...

We argue that promoting education may be a means to reduceincome inequality. When workers of different skill levels areimperfect substitutes in production, an increase in the level ofhuman capital in the economy reduces the return to education.Hence, a given compression of after-tax incomes can...

Various economic theories are available to explain the existence of credit and default cycles. There remains empirical ambiguity, however, as to whether or these cycles coincide. Recent papers_new suggest by their empirical research set-up that they do, or at least that defaults and credit...
