In recent years, the number of research and development (R&D) partnerships between firms has substantially increased. From the perspective of the individual firm, these partnerships are formed in order to share the risks and benefits of R&D. At the macro level, they result in a global spanning...

We present a simple dynamic model to rationalize extended “panic buying” episodes. In our model, consumers compete for a scarce good. Scarcity is triggered by an anticipated negative supply shock that takes place in a single period with positive probability. To avoid the risk of...

It is well-established that incumbent firms may try to deter new market entry by pretending to be stronger than they really are (e.g. by imitating the high output level of a low cost monopolist). In this article, we show that in some cases an incumbent may prefer the opposite, namely to...

We develop a model of social preferences for network games and study its predictions in a local public goods game with multiple equilibria. The key feature of our model is that players' social preferences are heterogeneous. This gives room for disagreement between players about the “right”...

Empirical work shows that networks of research and development alliances are asymmetric, with a small number of firms involved in the majority of partnerships. This article investigates the welfare-relevant effects of such concentrated networks in a model of network formation in an oligopolistic...

According to standard economic wisdom, fixed costs should not matter for pricing decisions. However, outside economics, it is widely accepted that firms need to increase their prices after a fixed cost rise. In this note, we show that a liquidity-constrained firm that maximizes lifetime profits...
