The rational expectations hypothesis is one of the cornerstones of current economic theorizing. This review discusses a number of experiments that focus on expectation formation by human subjects in a number of learning-to-forecast experiments and analyzes the implications for the rational...

Empirical work in macroeconomics almost universally relies on the hypothesis of rational expectations. This paper departs from the literature by considering a variety of alternative expectations formation models. We study the econometric properties of a popular New Keynesian monetary DSGE model...

This paper studies the formulation of monetary policy in a changing environment when knowledge regarding some aspects of the structure of the economy is imperfect and an adaptive learning technology is available to the policymaker and economic agents. As a benchmark, we develop a simple model of...

The rational expectations hypothesis is one of the cornerstones of current economic theorising. This review discusses a number of experiments that focus on expectation formation by human subjects and analyses the implications for the rational expectations hypothesis. The experiments show that...

Learning process is a new approach of filling the gap between adaptive expectations and rational expectations. Private agents are learning new information and adjust their expectation about the inflation and output gap. Central bank transparency is one of the key factors of learning by private...

Der Bericht stellt den Wirtschaftsnobelpreis 1995 für Robert E. Lucas zur Diskussion. Dabei wird die Entwicklung der Forschungsinhalte des Preisträgers gewürdigt. Bekanntgeworden ist Robert Lucas in den siebziger Jahren neben der Übertragung der rationalen Erwartungen auf die Makroökonomik...

In this paper, we study the effectiveness of monetary policy in a severe recession and deflation when nominal interest rates are bounded at zero. We compare two alternative proposals for ameliorating the effect of the zero bound: an exchange-rate peg and price-level targeting. We conduct this...

In this paper we estimate a small model of the euro area to be used as a laboratory for evaluating the performance of alternative monetary policy strategies. We start with the relationship between output and inflation and investigate the fit of the nominal wage contracting model due to Taylor...
