We report the results of a laboratory experiment, in which we observed the behavior of agents in a simple macroeconomic setting. The core question of this paper is whether standard macroeconomic models generate correct predictions despite their unrealistic assumptions of prefectly rational...

Previous experimental investigations have shown that expectations are not perfectly rational due to bias. Traditional adaptive models, however, in many cases do not perfectly describe the formation of expectations either. This paper makes two contributions to the experimental literature on the...

In this paper we report the results of a laboratory experiment, in which we observed the behavior of agents in a simple macroeconomic setting. The structure of the economy was only partially known to the players which is a realistic feature of our experiment. We investigate whether subjects...

Macroeconomics must take radical uncertainty into account, if it aims at contributing to the solution of serious real-world problems such as climate change. Allowing for radical uncertainty must happen at two levels: the level of modeling and the level of the scientific discipline. I argue that...

According to the expectations channel, a fiscal consolidation may give rise to less contractionary, or even expansionary effects on consumption, despite a decline in current disposable income. Intuitively, people may accumulate a stock of savings in anticipation of the consolidation and may...
