November 15: Christopher Stapenhurst (QSMS Seminar)

Christopher Stapenhurst (QSMS) will present “Red and Gold (with Andrew Clausen and John Moore)” on November 15th, 2024, at 10:30 AM, in room QA406.

Abstract:   

Clausen and Stapenhurst (2024) obtain a lower bound on the cost of the optimal static, bribe-proof mechanism. But what about dynamic mechanisms? We propose a mechanism called “Red and Gold” that uses a nuisance action to deter bribes at arbitrarily small cost. The agent receives either a red or a gold ticket. If the monitor reports shirking then she is asked to guess the colour of the agent’s ticket. If the monitor’s guess is correct, then she receives an arbitrarily small reward, and the agent receives a large fine. Otherwise, the agent gets no fine. It follows that any equilibrium belief of the monitor leaves exactly one of the agent’s types better off rejecting bribes. But then the monitor can perfectly infer the agent’s type, so the type that rejects bribes would be better off accepting them. Hence there can be no bribes in equilibrium.

November 22: Noé Ciet (QSMS Seminar)

Noé Ciet (QSMS) will present “Bailout Policies when Banks Compete with Switching Costs (with Marianne Verdier)” on November 22nd, 2024, at 10:30 AM, in room QA406.

Abstract:   

We analyze the effects of bailout policies on borrower surplus in a two-period Hotelling model of competition with switching costs and poaching. Before the second period of competition, banks may sometimes fail or face capacity constraints because of random shocks and uncertain bailouts. If borrowers are myopic, banks reduce the first-period interest rates according to their bailout expectations. We show that banks may reduce the first-period interest rates even more when borrowers anticipate a bank failure in the second period, whereas they may sometimes add a mark-up to the first-period interest rates if borrowers expect the market to remain stable. Higher bailout expectations have a different impact on the interest rates in markets with high and low switching costs. We derive the bailout policy that maximizes borrower surplus and show that it may sometimes be time-inconsistent.
