We study the optimal strategy of a durable-goods monopolist who can offer goods in different qualities. The key finding is that the presence of the additional sorting variable further undermines the firm's commitment problem, leading to results that contrast sharply with those of standard...

We show that in contrast to results in the extant literature, single sourcing may not be the optimal strategy of a buyer facing suppliers with strictly convex costs. As we argue, previous findings relied crucially on the joint assumption that, first, there is only a single buyer and that,...

Contract design under incomplete information is often analysed in a bilaterally monopolistic setting. If the informed party's reservation value does not depend on its private information (its type), it is a standard result that the uninformed side offers "low" types distorted contracts to reduce...

We analyze the short- and long-run implications of third-degree price discrimination in input markets. In contrast to the extant literature, which typically assumes that the supplier is an unconstrained monopolist, in our model input prices are constrained by the threat of demand-side...

Based on recent developments in competition theory, we analyze key aspects of buyer power. The main perspective that we take is one where buyer power is treated as bilateral bargaining power. This represents a key difference from the more standard approach that views buyer power through the...

In an internal capital market, individual departments may compete for a share of the firm´s budget by engaging in wasteful influence activities. We show that firms with more levels of hierarchy may experience lower influence costs than less hierarchical firms, even though the former provide...

We analyze the incentives of a vertically integrated firm to foreclose downstream rivals in a model of upstream price competition between suppliers of only imperfectly substitutable inputs. Our main motivation is a critical assessment of common assertions that draw inferences from pre-merger...
