This paper investigates the influence of physical attractiveness on cooperative behavior. We survey data from 211 episodes of a television game show and combine it with independent facial attractiveness ratings of the show's contestants. The final of the show represents a simultaneous one-shot...

While both public and private financial agencies supply asset markets with large quantities of information, they do not necessarily disclose all asset-related information to the general public. This observation leads us to ask what principles might govern the optimal disclosure policy for an...

We use laboratory experiments to test for one of the foundations of the rational voter paradigm - that voters respond to probabilities of being pivotal. We exploit a setup that entails stark theoretical effects of information concerning the preference distribution (as revealed through polls) on...

This article analyzes the effects of intellectual property rights in a qualityladder model in which incumbent firms preemptively innovate in order to keep their position of leadership. Unlike in models with leapfrogging, granting nonexpiring forward protection reduces the rate of innovation and...

Higher-dimensional symmetric games become of more and more importance for applied micro- and macroeconomic research. Standard approaches to uniqueness of equilibria have the drawback that they are restrictive or not easy to evaluate analytically. In this paper I provide some general but...

Almost all important decisions in people's lives entail risky and delayed consequences. Regardless of whether we make choices involving health, wealth, love or education, almost every choice involves costs and benefits that are uncertain and materialize over time. Because risk and delay often...

In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...

Many statistical applications require the forecast of a random variable of interest over several periods into the future. The sequence of individual forecasts, one period at a time, is called a path forecast, where the term path refers to the sequence of individual future realizations of the...

I present a game-theoretic model where economic competition and attention competition are interdependent. On the one hand the effort to attract consumer attention depends on the value of attention to the firm which depends on the grade of price competition among all perceived firms. On the other...
