To address the relationship between innovation and competition we jointly estimate the opportunity, production, and impact functions of innovation in a simultaneous system. Based on Swiss micro-data, we apply a 3-SLS system estimation. The findings confirm a robust inverted-U relationship, in...

I study the simultaneous ownership of equity of competing companies by the same investor, i.e., common ownership, in 39,867 publicly listed corporations in 125 countries between 2000-2020. I construct a global data set to document the prevalence of common ownership in multiple forms, including...

This paper evaluates four publicly discussed policy options to mitigate market power in the German wholesale electricity market. These four options are: a regulatory solution favoured by the Federal Ministry for Economics and Technology, the implementation of a day-ahead flow-based market...

The purpose of this paper is to investigate the market concentration, foreign ownership and determinants of profitability for commercial banks operating in the MENA economies over the period 1999-2012. This paper uses panel analysis via GMM estimation to examine a large sample of banks for a...

The ownership of competing firms by investment funds, or common ownership, can cause anti-competitive product market outcomes. This paper examines the price effects of common ownership in the Western Australian (WA) retail gasoline market. Using a rich data set of daily, station-level petrol...
