Although uncertainty plays an important role in economic decisionmaking, empirical measures of individuals' uncertainty are rare. The literature on cognition and communication documents that people use round numbers to convey uncertainty. This paper introduces a method of quantifying the...

Measuring economic uncertainty is crucial for understanding investment decisions by individuals and firms. Macroeconomists increasingly rely on survey data on subjective expectations. An innovative approach to measure aggregate uncertainty exploits the rounding patterns in individuals' responses...

This paper is the first attempt to investigate the performance of different learning rules in fitting survey data of household and expert inflation expectations in five core European economies (France, Germany, Italy, Netherlands and Spain). Overall it is found that constant gain learning...

We review and evaluate methods previously adopted in the applied literature of adaptive learning in order to initialize agents' beliefs. Previous methods are classified into three broad classes: equilibrium-related, training sample-based, and estimation-based. We conduct several simulations...

We develop a novel characterization of participants’ forecasts with a mixture of normal variables arising from a Markov component. Using this characterization, we formulate five behavioral specifications, including four implied by the diagnostic expectations approach, as well as three implied...

The communication policy of the European Central Bank attracts a lot of attention from financial markets. This paper analyses the informational content of the monthly introductory statements of the ECB president explaining interest rate decisions with regard to inflation expectations of...

Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under adaptive learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the...

The recent macroeconomic literature stresses the importance of managing heterogeneous expectations in the formulation of monetary policy. We use a stylized macro model of Howitt (1992) to investigate inflation dynamics under alternative interest rate rules when agents have heterogeneous...

We derive the optimal monetary policy in a sticky price model when private agents follow adaptive learning. We show that this slight departure from rationality has important implications for policy design. The central bank faces a new intertemporal trade-off, not present under rational...
