Rational Expectations in Games
Modern game theory was born in 1928, when John von Neumann published his Minimax Theorem. Inter alia, this theorem ascribes to all two-person zero-sum games a value—what rational players should expect to get. Almost 80 years later, strategic game theory has not gotten beyond that initial point, insofar as the basic question of value is concerned. To be sure, we do have equilibrium theories: the...
متن کاملTesting for Stochastic Non- Linearity in the Rational Expectations Permanent Income Hypothesis
The Rational Expectations Permanent Income Hypothesis implies that consumption follows a martingale. However, most empirical tests have rejected the hypothesis. Those empirical tests are based on linear models. If the data generating process is non-linear, conventional tests may not assess some of the randomness properly. As a result, inference based on conventional tests of linear models can b...
متن کاملRational Expectations in Urban Economics∗
Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under reasonable modifications for this field. An open subset of economies where none of the modified rational expectatio...
متن کاملRational Inattention and Aggregate Fluctuations
This paper introduces the rational inattention hypothesis (RI) – that agents process information subject to finite channel constraints – into a stochastic growth model with permanent technology shocks. We find that RI raises consumption volatility relative to output by introducing an endogenous demand shock. Furthermore, it is shown that incorporating RI can provide an additional internal propa...
متن کاملLearning Within Rational-Expectations Equilibrium
Models of macroeconomic learning are populated by agents who possess a great deal of knowledge of the “true” structure of the economy, and yet ignore the impact of their own learning on that structure; they may learn about an equilibrium, but they do not learn within it. An alternative learning model is presented where agents’ decisions are informed by hypotheses they hold regarding the economy...
