This paper characterizes efficient tax subsidies for charitable contributions, and considers the properties of potential reforms. Contributions are underprovided in the absence of subsidies, and are misdirected if subsidies fail to account for all of the costs that donors incur. It is costly for...

This paper revisits the link between education-based marriage market sorting and income inequality. Leveraging Danish administrative data, we develop a novel categorization of marriage market types based on the starting wages and wage growth trajectories associated with educational programs:...

The incorporation of increasing returns and imperfect competition into applied general-equilibrium (AGE) models, beginning with Harris (1984), led to much larger welfare effects from changes such as trade liberalization. But the imperfect competition side of these IO developments has often...

In the past there was hardly any use of economic instruments in environmental policy, mainly command and control measures were used. More recently, ecological taxes as well as tradable permits became more popular and voluntary agreements have been implemented. Using the Public Choice approach we...

This paper presents a new approach to the theory of the firm by identifying factor complementarities as central to the determination of the firm's boundaries. The factor complementarities, as well as economies of scale and scope. We examine the tradeoff between the gains froom these...

This paper presents a positive model which shows that institutional setups on capital and labor markets might be intertwined by politicoeconomic forces. Some countries especially in continental Europe exhibit a corporatist politicoeconomic equilibrium with a sustantial protection of insiders on...

The paper examines of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organisation away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the exsisting literature on the division of labour...

We examine wage competition in a model where identical workers choose the number of jobs to apply for and identical firms simultaneously post a wage. The Nash equilibrium of this game exhibits the following properties: (i) an equilibrium where workers apply for just one job exhibits unemployment...

In this paper it is shown that allowing the deduction of work-related expenses has a strictly positive effect on tax efficiency only if two conditions hold jointly: (i) The expenses should be interpretable as real cost and (ii) the expenses should be required for increasing taxable income....

The present note analyzes the Simultaneous Ascending Bid Auction with arbitrarily many bidders with decreasing marginal valuations under complete information. We show that the game is solvable by iterated elimination of weakly dominated strategies if the efficient allocation assigns at least one...
