Policy makers are increasingly concerned about the combination of market power and massive data collection in digital markets. This concern is fueled by the theoretical prediction that more market power causes firms to collect ever more data from their users. We investigate the relationship...

This paper presents an analysis of the recent developments of average market power in Europe by using a broad firm-level database for EU member states. To indicate competitive pressure at the firm-level, markups are estimated following De Loecker (2011), and De Loecker and Warzynski (2012). The...

We study the role of privacy in the market for mobile applications. For such programs used with smartphones and tablet PCs a very important market has emerged. Yet, neither the role of privacy on that market is well understood, nor do we have empirical evidence regarding its role therein. We...

Although blockchain technology and cryptocurrencies have grown in popularity over the past years, there does not seem to be a consensus if they bring any value to economic interactions. In this paper, I argue that a fundamental value the blockchain provides is commitment. I develop a model of an...

In this study, we analyze the cyclicality of fiscal policies in China during the period 1978-2013. We find that the cyclicality of local government spending in China significantly affects the cyclicality of total government spending. By employing both time-series and province-level panel data,...

We advance the literature on political budget cycles by testing separately for cycles in expenditures for elections in the legislative and the executive. Using municipal data, we can separately identify these cycles and account for general year effects. For the executive branch, we show that it...

This paper exploits detailed information on local political and socioeconomic networks and a reform of local fiscal equalization in North Rhine-Westphalia (NRW) to identify the role of learning in local tax rate interactions. Using this policy change in spatial lag IV regressions, we find that...

While there is a large and growing number of studies on the determinants of corporate tax rates, the literature has so far ignored the fact that the behavior of governments in setting tax rates is often best described as a discrete choice decision problem. We set up an empirical model that...

Recent literature has emphasized that redistributive grant systems may tend to internalize fiscal externalities arising from tax competition. This paper further explores the conditions under which local grant systems enforced by the state government will enhance efficiency. A system of...

This paper examines the factors determining vertical government structures. An empirical analysis for a panel of OECD countries indicates that apart from preferences, economies of scale, and other factors, institutions explain cross-national differences in the degree of fiscal decentralization....
