This paper studies the design of optimal fiscal policy when a government that fully trusts the probability model of government expenditures faces a fearful public that forms pessimistic expectations. We identify two forces that shape our results. On the one hand, the government has an incentive...

Das Papier zeigt zunächst mögliche Gründe und Ursachen für die Errichtung und die Bewahrung unabhängiger Institutionen in demokratischen Rechtsstaaten auf. Danach werden formelle und behavioralistische Kriterien benannt, anhand derer der Grad der Unabhängigkeit auf einem Kontinuum zwischen...

Recent theoretical work has shown the importance of measuring microeconomic uncertainty for models of both general and partial equilibrium under imperfect insurance. In this paper the assumption of i.i.d. income innovations used in previous empirical studies is removed and the focus of the...

We examine in an experiment the causes, consequences and possible cures of myopic loss aversion (MLA) for investment behaviour under risk. We find that both, investment horizons and feedback frequency contribute almost equally to the effects of MLA. Longer investment horizons and less frequent...

This paper examines how time to build alters strategic investment behaviour under oligopoly. Facing demand uncertainty, firms decide whether to invest early or wait until uncertainty has been resolved. A game that captures time-to-build investment is contrasted with another one in which...

We extend the Bikhchandani, Hirshleifer and Welch (1992) informational cascade framework to allow for asymmetric signal accuracy. Simulations demonstrate that even small departures from symmetry may lead to non-monotonic effects of signal accuracy on the likelihood of an inefficient cascade.

Medical expenditure risk can pose a major threat to living standards. We derive decomposable measures of catastrophic medical expenditure risk from reference-dependent utility with loss aversion. We propose a quantile regression based method of estimating risk exposure from cross-section data...

The impact of uncertainty on firms' investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...

Although the standard work week is longer in East than in West Germany, there is a higher incidence and average amount of unpaid overtime worked in the new states. We try to explain the striking differences in unpaid overtime by analyzing the labor supply side. We focus on the investment...

ROC curves from the signal detection literature are used in an evolutionary analysis of one-shot and repeated prisoners' dilemmas: showing if there is any discounting of future payoffs, or any cost of searching for an additional partner, then cooperative players who contingently participate - in...
