Despite the continuing political interest in the usefulness of tax competition and tax coordination as well as the wealth of theoretical analyses, it still remains open whether or when tax competition is harmful. Moreover, the influence of tax differentials on multinationals' decisions is still...

To what extent does a tax credit affect firms ́R&D activity? What are the mechanisms? This paper examines the effect of R&D tax credits on firms ́R&D expenditure by exploiting the variation across firms in the changes in the eligible tax credit rate between 2000 and 2003. Estimating the...

We assume that a project requires an initial outlay and may either succeed or fail. The probability of success depends on its type and on the effort of the firm. Only in the case of success do private and external benefits appear. The paper analyzes the optimal design of subsidies under...

This paper elaborates on the recent race to sequence the human genome. Starting from the debate on public vs. private research arising from the genome case, the paper shows that in some fundamental research areas, where knowledge externalities play an important role, market and non-market...

The U.S. and EU Merger Guidelines strongly emphasize the relevance of the "ease of entry" argument in merger evaluations. Up to now, very little is known empirically about how mergers affect entry and exit, and the resulting number of firms in the markets. We empirically test this aspect of...

Aspirations towards technological sovereignty increasingly pervade the political debate. Yet, an ambiguous definition leaves the exact goal of those aspirations and the policies to fulfill them unclear. This leaves room for partly particularly negative interpretations, such as equating the...

Mergers realize heterogeneous competitive effects on profits, production, and prices. To date, it is unclear whether differential merger outcomes are caused mostly by firms' technology or product market attributes. Furthermore, empirical merger studies conventionally assume that, conditional on...

Pharmaceutical firms spend increasing amounts in mergers and acquisitions (M&As), which raises the question of whether sufficient investment is left after mergers to further develop firms' internal drug development capability. We evaluate the effects of M&As on firms' post-merger R&D...

In this paper, we investigate distortions created by turnover taxes. As a natural experiment, we explore a reform that replaced turnover taxes with value-added taxes for some service industries in China, while the taxation of manufacturing industries remained unchanged. The reform increased...

The theoretical literature on the economics of fiscal federalism has identified several potential effects of government decentralization on economic growth. Much of the traditional literature focuses on the efficiency aspects of a decentralized provision of public services. However,...
