We examine behavior in Cournot and Stackelberg markets in a simple experiment where participants experience both market forms. Moreover, Stackelberg followers have to submit full response strategies. Our main finding is that Stackelberg followers employ rather flat, reciprocal response function,...

We study behavior in an investment experiment conducted with a representative sample of German households (SOEP-IS). Respondents allocate a fixed budget between a safe asset and a risky asset whose returns are tied to the German stock market and earn monetary returns based on their decisions....

We study the merger paradox, a relative of Harsanyi's bargaining paradox, in an experiment. We examine bilateral mergers in experimental Cournot markets with initially three or four firms. Standard Cournot-Nash equilibrium predicts total outputs well. However, merged firms produce significantly...

We analyze a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. We show that export tariffs are...

We present evidence from a natural field experiment and structural model to shed light on the efficacy of alternative fundraising schemes. In conjunction with the Bavarian State Opera, we mailed 25,000 opera attendees a letter describing a charitable fundraising project organized by the opera...

When asking for donations, charitable organizations often suggest a potential amount to contribute. However, the evidence concerning the effects of such suggestions is scarce and inconsistent. Unlike the majority of earlier studies concerned with small-money solicitations, we examine the effect...

In this note we shall discuss a concept that – despite its prominence in both Hume (1739) and Smith (1759), its obvious relevance for social behavior, and its not so infrequent use in colloquial language – has never gained a foothold in economic theory: the concept of empathy. Specifically,...

In many economic contexts, an elusive variable of interest is the agent's belief about relevant events, e.g. about other agents' behavior. A growing number of surveys and experiments asks participants to state beliefs explicitly but little is known about the causal relation between beliefs and...
