We consider a two-player contest model in which breakthroughs arrive according to privately observed Poisson processes. Each player's process continues as long as she exerts costly effort. The player who collects most breakthroughs until a predetermined deadline wins a prize.We derive Nash...

Häufig unterlaufen Kartelle wettbewerbsrechtliche Beschränkungen und werden illegal tätig. Der Autor beleuchtet die empirischen Schwierigkeiten, die sich daraus für die Kartellforschung ergeben. Auf der Ebene der Kartelltheorie stellt sich das Problem, daß die verwendeten spieltheoretischen...

This paper analyzes the role of communication between firms in an infinitely repeated Bertrand game in which firms receive an imperfect private signal of a common value i.i.d. demand shock. It is shown that firms can use stochastic, inter-temporal market sharing as a perfect substitute for...

We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...
