This paper constructs a small open economy version of the two sector Benhabib-Farmer (1996) indeterminacy model. It can be shown that sunspot equilibria arise at significantly lower magnitude of increasing returns to scale than in the original dosed economy model. Furthermore, if a mix of...

In this paper I consider a complex decision problem where subjects have to cope with a time horizon of uncertain duration and must update their termination probabilities which depend on stochastic events during life. First I describe how economic theory suggests to solve the decision problem....

Unit root tests are considered for time series which have a level shift at a known point in time. The shift can have a very general nonlinear form and additional deterministic mean and trend terms are allowed for. Prior to the tests the deterministic parts and other nuisance parameters of the...

We identify some of the requirements for document integration of software components in statistical computing, and try to give a general idea how to cope with them in an implementation.

VaR models are related to statistical forecast systems. Within that framework different forecast tasks including Value-at-Risk and shortfall are discussed and motivated. A backtesting method based on the shortfall is developed and applied to VaR forecasts of areal portfolio. The analysis shows...

In this paper we present an experiment on the false consensus effect. Unlike previous experiments, we provide monetary incentives for revealing the actual estimation of others' behavior. In each session and round sixteen subjects make a choice between two options simultaneously. Then they...

Experimental studies of risk and time-preference typically focus on one of the two phenomena. The goal of this paper is to investigate the (possible) correlation between subjects' attitude to risk and their time-preference. For this sake we ask 61 subjects to price a simple lottery in 3...

Although stock splits seem to be a purely cosmetic event, there exists ample empirical evidence from the United States that stock splits are associated with abnormal returns on both the announcement and the execution day, and additionally with an increase in variance following the ex-day. This...
