Stochastic Utility Theorem

This paper analyzes individual decision making under risk. It is assumed that an individualndoes not have a preference relation on the set of risky lotteries. Instead, an individual possesses a probability measure that captures the likelihood of one lottery being chosen over the other. Choice probabilities have a stochastic utility representation if they can benwritten as a non-...

On the interaction between risk sharing and capital accumulation in a stochastic OLG model with production

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimal competitive equilibrium allocations. Furthermore, we provide
tests of Pareto optimality/suboptimality based on (risky) rates of return only.

The great capitol hill baby sitting co-op: Anecdote or evidence for the optimum quantity of money?

This paper studies a centralized market with idiosyncratic uncertainty and money as a medium of exchange from a theoretical as well as an experimental perspective. In our model, prices are fixed and markets are cleared by rationing. We prove the existence of stationary monetary equilibria and of an optimum quantity of money.

Why does implied risk aversion smile?

Implied risk aversion estimates reported in the literature are strongly U-shaped. This article explores different potential explanations for these “smile” patterns: (i) preference aggregation, both with and without stochastic volatility and jumps in returns, (ii) misestimation of investors’ beliefs caused by stochastic volatility, jumps, or a Peso problem, and (iii) heterogeneous...

Approximate generalizations and computational experiments

In this paper I demonstrate how one can generalize finitely many examples to statements about (infinite) classes of economic models. If there exist upper bounds on the number of connected components of one-dimensional linear subsets of the set of parameters for which a conjecture is true, one can conclude that it is correct for all parameter values in the class considered, except for...

Auswirkungen eines Hochrisikopools auf die Risikoselektion im Schweizer Krankenversicherungs-Wettbewerb: Eine empirische Klärung

Pay-TV vs. Free-TV: A model of sports broadcasting rights sales

INTRODUCTION In recent years, the importance of income from broadcasting rights for professional sports clubs' revenues has increased significantly both in the U.S. and in Europe [see Cave and Crandall, 2001]. While up to the 1980s gate receipts have constituted the major pillar of revenues, this role has since been taken over by income out of broadcasting rights sales [Andreff...

Managerial Guidance and Analysts' Underreaction

Empirical investigations of analysts forecast surveys concerning earnings realizations find significant time varying biases usually attributed to the analysts liability to cognitive limitations. For example, a positive autocorrelation of analysts forecast errors is commonly explained by analysts underreaction. In this paper we develop a random dynamical system describing the...
