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...

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...

This paper analyzes the efficient taxation of oil and capital income in an oil-dependent infinite-lived economy facing perfect capital mobility. Two cases are examined: one with product market imperfections and free tax choice, one with perfect competition and tax restrictions. The optimal tax...

Recent literature has investigated whether the welfare gains from environmental taxation are larger or smaller in a second-best setting than in a first-best setting. This question has mainly been addressed indirectly, by asking whether the second-best optimal environmental tax is higher or lower...

This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE...

Fiscal considerations may shift governmental priorities away from environmental concerns: Finance ministers face strong demand for public expenditures such as infrastructure investments but they are constrained by international tax competition. We develop a multi-region model of tax competition...
