We study optimal unemployment insurance (UI) over the business cycle using a heterogeneous agent job search model with aggregate risk and incomplete markets. We validate the model-implied micro and macro labor market elasticities to changes in UI generosity against existing estimates, and...

The costs of searching for a job vacancy are typically associated with friction that deters or delays employment of potentially productive individuals. We demonstrate that in a labor market with moral hazard where effort is noncontractible, job search costs play a positive role, whose effect may...

We analyse the effects active labour market programmes (ALMPs) have on unemployment in a union wage-setting framework when search is endogenous. We assume that a union president, elected by majority voting determines the wage. We analyse the case where ALMPs increase match efficiency of the...

While examining the macroeconomic effects of increased government control of the informal sector, this paper develops a two-sector general equilibrium model featuring matching frictions on the labour market and a social norm. Conducting informal work, or employing a worker infor- mally, is...

While examining the macroeconomic effects of government tax and punishment policies, this paper develops a three-sector general equilibrium model featuring matching frictions and worker-firm wage bargaining. Workers are assumed to differ in ability, and the choice of education is determined...

This paper provides an assessment of Greenland's tax system and contemplates changes that may be undertaken in the future to prepare for greater economic self-reliance and for the country's participation in the wider world economy. At the outskirts of Europe, Greenland is an autonomous part of...

This paper examines the implications of that workers may not be able to estimate their true costs of acquiring skills. Consequently, too few workers may acquire skills. This allows for the possibility that subsidizing education is welfare improving. Furthermore, if the presence of skill-biased...

This paper examines the effect of taxes on the individuals' choices of educational direction, and thus on the economy.s skill composition. A proportional labour tax induces too many workers with high innate ability to choose an educational type associated with high consumption value and low...

This paper develops a general equilibrium search and matching model where an underground economy co-exists along with the formal part of the economy. In analyzing how tax and punishment policies affect labour market performance, we nd that punishment of infor- mal sector activities induce...
