This paper studies the implications of an increase in the price of necessities, which disproportionally hurts the poor, for optimal income taxation. Our analyses show that, when the government is utilitarian and disutility from labor supply is linear, the optimal net nominal tax schedule is...

CO2 emissions are disproportionately caused by more affluent consumers. In the political debate, this fact has triggered the demand for income redistribution and wealth taxes not only to reduce inequality but also to reduce CO2 emissions. This paper calculates the possible size of such a green...

This paper studies the distributional consequences of a systematic variation in expenditure shares and prices. Using European Union Household Budget Surveys and Harmonized Index of Consumer Prices data, we construct household-specific price indices and reveal the existence of a pro-rich...

Tax rates on corporate income have considerably come down in the process of tax competition and further pressures are evident. Against this background, the paper discusses possible benefits of corporate income taxation that may be at risk. In particular, the paper surveys the empirical evidence...

This paper considers the efficiency of a contestable natural monopoly if consumers are heterogeneous and the monopolist can differentiate prices imperfectly. With restricted entry, the standard result in this case is that the monopoly offers a menu of price-quantity combinations which leads to...

Tax neutrality towards alternative financing instruments for corporate investment is a ubiquitous demand in the political debate. At the same time, the literature is surprisingly silent about the magnitude of possible efficiency costs of a departure from tax neutrality. Against this background,...

The paper evaluates the working of German CFC rules that restrict the use of foreign subsidiaries located in low-tax countries to shelter passive investment income from home taxation. While passive investments make up a significant fraction of German outbound FDI, we find that German CFC rules...

By granting intracompany loans to their foreign affiliates, multinational firms may reduce their tax liability abroad. Many countries have legislated thin-capitalization rules (TCRs) that limit the allowable levels of intracompany loans or restrict interest deductibility if certain thresholds...
