| Abstract: | This paper discusses the general characteristics of online markets from a competition theory perspective and the implications for competition policy. Three important Internet markets are analyzed in more detail: search engines, online auction platforms, and social networks. Given the high level of market concentration and the development of competition over time, we use our theoretical insights to examine whether leading Internet platforms have non-temporary market power. Based on this analysis we answer the question whether any specific market regulation beyond general competition law rules is warranted in these three online markets. -- |

| Abstract: | Democracy and media freedom have been suggested as useful tools in the fight against political corruption, but so far their interplay in this fight has received scant attention. We present a game theoretic model which predicts that the corruption-reducing effect of democracy becomes stronger as media freedom increases. Using panel data covering the period 1980-2008 and 126 countries, we find empirical support for this prediction. Our main results hold when we control for the effects of income, time varying common shocks, regional fixed effects and various additional covariates. The complementarity between democracy and media freedom in the fight against corruption is also supported by Indian state level data. |
