We estimate the impact of bank merger announcements on borrowers' stock prices for publicly traded Norwegian firms. Borrowers of target banks lose about 0.8% in equity value, while borrowers of acquiring banks earn positive abnormal returns, suggesting that borrower welfare is influenced by a strategic focus favoring acquiring borrowers. Bank mergers lead to higher relationship…

There is abundant evidence that many individuals violate the rationality assumptionsnroutinely made in economics. However, powerful evidence also indicates that violations ofnindividual rationality do not necessarily refute the aggregate predictions of standard economicnmodels that assume full rationality of all agents. Thus, a key question is how the interactions between rational…

We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reducedform framework. For this general framework, we establish the following main results: First, vertical integration increases own investment and decreases competitor investment (intimidation…

In the absence of trust among trading partners, market transactions break down. In the absence of trust in a country's institutions and leaders, political legitimacy breaks down.

Wenstudy a simple experimental principal-agent game, where the principal decides whethernhe controls the agent by implementing a minimum performance requirement before the agent chooses a productive activity. Our main finding is that a principal's decisionnto control has a negative impact on the agent…

"The most fundamental solution concepts in Game Theory – Nash equilibrium, backward induction, and iterated elimination of dominated strategies – are based on the assumption that people are capable of predicting others' actions. These concepts require people to be able to view the game from the other players’ perspectives, i.e. to understand others’ motives and beliefs.…
