I extend multi-unit auction estimation techniques to a setting in which firms can express cost complementarities over time. In the context of electricity markets, I show how the auction structure and bidding data can be used to estimate these complementarities, which in these markets arise due...

Barriers to international trade are known to be large but due to data limitations it is hard to measure them directly for a large number of countries over many years. To address this problem I derive a micro-founded measure of bilateral trade costs that indirectly infers trade frictions from...

Assets in the fossil fuel industries are at risk of losing market value due to anticipated breakthroughs in renewable technology and governments stepping up climate policies in the light of the Paris commitments to limit global warming to 1.5 or 2 degrees Celsius. Stranded assets arise due to...

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle privately, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. Despite the additional costs of...

The data indicate that non-wage labour costs in Germany have reached a record high in recent years. From 1972 to 2001, the ratio of non-wage labour costs to direct compensation in West German manufacturing industry rose from 55.6 per cent to 81.2 per cent. The topic of non-wage labour costs is...

This paper develops a quality-ladder model of endogenous growth to study the interplay between in-house R&D and marketing expenditure. Although promotional activity is modelled as purely wasteful competition among firms for attention, it unambiguously fosters innovation activity of firms, and...

In the context of supply function competition with private information, we test in the laboratory whether - as predicted in Bayesian equilibrium - costs that are positively correlated lead to steeper supply functions and less competitive outcomes than do uncorrelated costs. We find that the...

The paper investigates the relationships between costs and user charges in the sewage industry in Norwegian local governments. The purpose of the analysis is to answer the following questions: (i) To what extent is a higher unit cost passed on to consumers in terms of a higher user charge? (ii)...

Workers will not pay for general on-the-job training if contracts are not enforceable. Firms may if there are mobility frictions. Private information about worker productivities, however, prevents workers who quit receiving their marginal products elsewhere. Their new employers then receive...
