We empirically analyze the heterogeneous welfare effects of unemployment insurance and social assistance. We estimate a structural life-cycle model of singles' and married couples' labor supply and savings decisions. The model includes heterogeneity by age, education, wealth, sex and household...

This paper asks whether tax cycles can represent the optimal policy in a model without any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicevariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well...

We propose an equity finance model with agency problems and investigate the relationship between dividend taxation and inefficient investments. Contrary to both the old and the new view of dividend taxation, a fall in the dividend tax rate is found to improve corporate governance by increasing...

As a main principle, income is taxed when earned. This principle is broken in case of unrealized capital gains (recovered depreciations, unrecorded intangible assets etc.). Such incomes are taxed when realized or the ‘latent tax’ is passed on to the new owner (tax succession). In Denmark,...

This paper introduces an index of tax optimality that measures the distance of some current tax structure from the optimal tax structure in the presence of public goods. In doing so, we derive a [0, 1] number that reveals immediately how far the current tax configuration is from the optimal one...

Internationalization offers enhanced opportunities for individuals to place savings abroad and evade domestic saving taxation. This paper asks whether the concomi- tant loss of saving taxation necessarily is harmful. To this end we construct a model of many symmetric countries in which public...

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...

Can taxes on consumption redistribute in developing countries? Contrary to consensus, we show that taxing consumption is progressive once we account for informal consumption. Using household expenditure surveys in 32 countries we proxy for informal consumption using the type of store where...

We develop a framework to conduct experiments for estimating direct and spillover effects when units are grouped into mutually exclusive clusters. Crucially, our framework accounts for heterogeneous treatment effects across clusters and heterogeneous cluster sizes, which are pervasive in...

This paper evaluates the consequences of renewable energy policies on welfare, resource rents and energy costs in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. We use a global general equilibrium model with an intertemporal fossil...
