Prior research, primarily based on laboratory experiments of children and students, suggests that women might be more averse to competition than are men; women might, instead, be more inclined toward collaboration. Were these findings to generalize to working-age men and women across the...

This paper studies the competition between Web 2.0 communities in a game theoretic framework. We model three important features of these institutions: (i) firms' content is usually user-generated; (ii) consumers' content preferences are governed by local network effects, and (iii) consumers have...

Whoever exists belongs to a species, which did not become extinct, has a (geno-)type, which should be well adjusted, and lives in a habitat which has been sustainable for a long time. We do not only analyze interspecies competition and the conditions for species survival, but also intraspecies...

Social comparison theories typically assume a comparable degree of competition between commensurate rivals on a mutually important dimension. In contrast, however, the following set of studies reveals that the degree of competition between such rivals depends on their proximity to a standard....

There are many laws which require sellers to disclose private information about the quality of their products. But the theoretical justification for these laws is not obvious: economic theory predicts that a seller will voluntarily disclose such quality information, however unfavorable, as long...

I develop a dynamic investment game with a "memoryless" R&D process in which an incumbent and an entrant can invest in a new technology, and the entrant can also invest in the old technology. I show that an increase in the probability of successfully implementing a technology can cause the...

We study the following game: each agent i chooses a lottery over nonnegative numbers whose expectation is equal to his budget b_i. The agent with the highest realized outcome wins (and agents only care about winning). This game is motivated by various real-world settings where agents each choose...

The pioneering Pasternack returns-policy model (1985, 2008b) analyzed channel-coordination with a single supplier catering to a retailer facing stochastic demand for a perishable product with a fixed price, and showed that giving partial returns of unsold stock to the retailer is the optimal...

This chapter surveys recent theoretical developments in the intersection of price discrimination and imperfect competition, emphasizing how the introduction of competition fundamentally alters some well-established results derived from models of monopoly pricing

We examine optimal effort choice in a competition model where the agents are averse to low relative status and to exerting excessive effort. The game has a unique pure strategy Nash equilibrium. When the agents are homogeneous, a stronger competition incentive induces higher effort levels and...
