What is the optimal size of expert committees? To address this question, I present a model of a committee of experts with career concerns. Each expert may observe an argument about the state of the world and is unsure about the argument s soundness. Experts may remain silent or compete for the...

Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci and Siniscalchi (Economic Theory, 48:341-375, 2011) have recently axiomatised preferences in the presence of ambiguity as Monotonic Bernoullian Archimedean (MBA) preferences. We investigate the problem of Arrovian aggregation of MBA preferences...

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be su cient to make all agents in the river cooperate and acknowledge property rights as a prerequisite for...

When grades lose their informative value because the percentage of students receiving the best grade rises without any corresponding increase in ability, this is called grade inflation. Conventional wisdom says that such grade inflation is unavoidable since it is essentially costless to award...

We examine the herd behavior among equity funds in Germany based on a large sample of funds from 2000 to 2009. We show that a large portion of the detected herding can be explained by identical trading among funds of the same investment company. However, we also find statistically significant...

Private sector firms frequently sell dual use products that can be used to develop either civilian goods or weapons of mass destruction. The global character of these markets makes traditional regulation and treaty solutions difficult. Some existing initiatives by manufacturers have established...

Two firms produce a product with a horizontal and a vertical characteristic that we call quality. The difference in the quality levels determines how the firms share the market. Consumers do not observe quality before purchase. Under non-comparative advertising a firm signals its own quality,...
