Abstract: | 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 a gamble and the primary goal is to come out ahead. Such settings include patent
races, stock market competitions, and R&D tournaments. We show that there is a unique symmetric equilibrium when budgets are
equal. We proceed to study and solve extensions, including settings where agents choose their budgets (at a cost) and where
budgets are private information. |
