We develop a product market theory to explain why firms provide their workers with skills that are also useful to their competitors. Firms first decide whether to invest in industry‐specific training, then make wage offers for each others' trained employees and finally engage in imperfect product market competition. Equilibria with and without training can emerge. If competition is soft, firms invest in training if others do. Thereby, they avoid having to pay high wages for trained workers. Furthermore, we draw welfare conclusions from the analysis. Finally, we discuss how our ideas apply to supplier relationships and to general training.

In Germany, competitive franchising is increasingly being used to procure passenger railway services that were previously provided by a state monopolist. This paper analyzes 77 tenders that differ with respect to network size, service frequency, contract duration and the proximity to other lines that are already run by competitors of DB Regio, a subsidiary of the successor of the former state monopolist. Our analysis shows that competitors are more likely to win small networks and more recent auctions. Other controls such as contract duration and the adjacency to other lines run by entrants are insignificant.

We examine vertical backward integration in a reduced-form model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate vertically. As a result, integrated firms also tend to have a large market share. The driving force behind these findings are demand/mark-up complementarities in the product market. We also identify countervailing forces resulting from strong vertical foreclosure, upstream sales and endogenous acquisition costs.

We analyze the determinants of environmental policy when two industry lobbies can seek a laxer policy that would apply to both industries & loophole lobbying that provides benefits specific to one industry. We determine the properties of the lobbying equilibrium, including the resulting emissions level. In many cases, higher effectiveness of loophole lobbying is detrimental for industries & beneficial for environmental quality, as it exacerbates the free-rider problem in the provision of general lobbying by inducing industries to turn towards loophole lobbying.
