We study the interplay between a "one person-one vote" political system and a "one share-one vote" corporate governance regime. The political system sets Pigouvian subsidies, while corporate governance determines firm-specific public good investments. Our analysis highlights a two-way feedback...

This paper analyzes pricing decisions and competition in network markets, assuming that groups of consumers can coordinate their choices when it is in their interest, if coordination does not require communication. It is shown that multiple asymmetric networks can coexist in equilibrium. A...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

This paper performs a comparison of two well known approaches for modelling R&D spillovers associated with investment in green technology, namely D'Aspremont-Jacquemin and Kamien-Muller-Zang. We show that there is little qualitative difference between the models in terms of total surplus...

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...

We document non-linear stock effects in the relationship linking emerging technology adoption and network infrastructure increments. We exploit 2010-2017 data covering nascent to mature electric vehicle (EV) markets across 422 Norwegian municipalities together with two complementary...

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...

This paper studies the effect of an emission tax on the relocation decision in a duopoly with exogenous vertical product differentiation. We establish the relationship between quality difference, relocation cost, and marginal damage of emissions in a two-country-setting for three cases: An...
