Discretionary policymakers cannot manage private-sector expectations and cannot co- ordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. In order to utilize the explanatory power of models with...

We incorporate inferential expectations into the Barro-Gordon model (1983a) of time inconsistency and consider reputational equilibria. The range of sustainable equilibria shrinks as the private sector becomes more belief-conservative.

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

This paper studies the behavior of a central bank that seeks to conduct policy optimally while having imperfect credibility and harboring doubts about its model. Taking the Smets-Wouters model as the central bank.s approximating model, the paper's main findings are as follows. First, a central...

We study the identification and estimation of first-price auction models with independent private values where bidders are risk averse and there is ambiguity about the valuation distribution. When bidders' preferences are represented by the maxmin expected utility of [Gilboa and Schmeidler,...

This paper proposes a decision theoretic method to choose a single reserve price for partially identified auction models, such as Haile and Tamer, 2003, using data on transaction prices from English auctions. The paper employs Gilboa and Schmeidler, 1989 for inference that is robust with respect...

This paper shows an avenue through which a numerical inflation target ensures low inflation and high credibility: one that is independent of the usual Walsh incentive contract. Our novel game theoretic framework - a generalization of alternating move games - formalizes the fact that since the...

Empirical literature provided convincing evidence that explicit (ie legislated) inflation targets anchor expectations. We propose a novel game theoretic framework with generalized timing that allows us to formally capture this beneficial anchoring effect. Using the framework we identify several...

The paper considers a simple model in which monetary and fi?scal policies are formally independent, but still interdependent - through their spillovers onto the macroeconomic targets to which they are not primarilly assigned. It shows that the average equilibrium levels of inflation, deficit,...

The paper attempts to assess to what extent the central bank or the government should respond to developments that cause ?financial instability, such as housing or asset bubbles, overextended fi?scal policies, or excessive public or household debt. To analyze this question we set up a simple...
