I develop and estimate a model of pricing and advertising decisions of new car manufacturers and dealers. The model highlights a selling effort externality between dealers and manufacturers, which leads to estimated manufacturer markups that are about half compared to those from a model that...

New airline models are generational developments. For a particular market segment, a new model will be introduced perhaps every thirty years. Any new model will contain many innovations over the older model it supplants. Developing these innovations into an airliner introduces uncertainties,...

In the German automobile industry the vertical integration, as an indicator of value added, is on average low. Beyond the argument of relative high labour costs for manufacturing, several specific reasons for the level of vertical integration, linked to the flexibility of business administration...

We investigate the role of mutual trust in long-term vertical relationships involving trades of complex goods. High complexity is associated with high contract incompleteness and hence the increased relevance of trust-based relational contracts. Contrary to expectations, we find that changes in...

I develop a general framework for markup and markdown estimation that allows for profit sharing along value chains without making assumptions on conduct between vertically related firms. I derive the conditions under which the markup and markdown estimates relate to the firms' equilibrium...

We study the incentives of firms that hold partial vertical ownership to foreclose rivals. Compared to a full vertical merger, with partial ownership, a firm may obtain only part of the target's profit but may nevertheless be able to influence the target's strategy significantly. The target may...

Vertical integration followed by quantity competition is studied. In the first stage of the game downstream firms simultaneously decide whether to integrate with one of the upstream suppliers. If firms are not able to observe whether their vertically integrated competitor enters the...

This paper analyzes the impact of vertical integration on product quality. Contrary to previous findings, it is shown that integration decreases quality in many natural situations. In general, the direction of the quality change is governed by three effects that are isolated in the model. This...

I provide a justification of intellectual property rights as a source of static efficiency gains in manufacturing, rather than dynamic benefits from greater innovation. I develop a property-rights model of a supply relationship with two dimensions of non- contractible investment. In equilibrium,...
