Die Studie untersucht die Eigenschaften der Unternehmen, die als Erste in einen sich neu oeffnenden Markt investieren. Fuer den ersten Investor bestehen gewisse Vorteile (first-mover-advantages), die einen moeglichst fruehen Eintritt in den Markt nahe legen. Andererseits fuehrt die politische und wirtschaftliche Unsicherheit in Osteuropa zu einem Anreiz, die Investitionsentscheidung hinauszuzoegern, um von den Erfahrungen der anderen zu profitieren. Die Einflussfaktoren fuer die Wahl des Zeitpunktes der ersten Direktinvestition in Osteuropa werden anhand der Daten von rund 1000 Industrieunternehmen aus der Schweiz geschaetzt. Die Ergebnisse zeigen, dass grosse und international erfahrene Unternehmen aus dem Konsumgueterbereich einen fruehen Markteintritt bevorzugen. Zudem werden Direktinvestitionen, die auf den lokalen Markt ausgerichtet sind, frueher getaetigt als Investitionen zur Ausnutzung der niedrigen Arbeitskosten.

The goal of this paper is to introduce and illustrate a new approach to the stability analysis of sample-paths of nonlinear stochastic economic models with non-stationary components. We place our study within the mathematical theory of random dynamical systems and apply the concept of a random fixed point which is tailor-made for the study of the long-term behavior of sample-paths in stochastic systems. The main tool for the application of this approach is a Banach-type fixed point theorem for non-stationary random dynamical systems which is proved here. The concept and the theorem are thoroughly explained and illustrated by two examples from stochastic growth theory.

We show that concerns for fairness may have dramatic consequences for the optimal provision of incentives in a moral hazard context. Incentive contracts that are optimal when there are only selfish actors become inferior when some agents are concerned about fairness. Conversely, contracts that are doomed to fail when there are only selfish actors provide powerful incentives and become superior when there are also fair-minded players. These predictions are strongly supported by the results of a series of experiments. Furthermore, our results suggest that the existence of fair actors may be an important reason why many contracts are left deliberately incomplete.

This paper examines the effects of deficits spending on the Nazi recovery. Although deficits were substantial and full employment was reached within four years, their fiscal impulse was too small to account for the speed of recovery. VAR forecasts of output using fiscal and monetary policy instruments also suggest only a minor role for active policy. Nazi policies deliberately crowded out private demand to ensure high rates of rearmament. Military spending dominated civilian work-creation already in 1934. Investment in autobahn construction was minimal during the recovery and gained momentum only in 1936 when full employment was approaching. We find some effects of the Four Years Plan of late 1936, which boosted government spending further and tightened public control over the economy.

This paper surveys recent advances in the application of random dynamical systems theory in economics. It illustrates the usefulness of this framework for modeling and analysis of economic phenomena with stochastic components, mainly focusing on stochastic dynamic models in economic growth. The paper also highlights some directions for further applications and interdisciplinary research on random dynamical systems.

This paper presents a complete analysis of a stochastic version of the Solow growth model in which all parameters are ergodic random variables. Applying random dynamical systems theory, we prove that the dynamics and, in particular, the long-runnbehavior is uniquely determined by a globally attracting stable random fixed point. We also discuss the relation of our approach to that of ergodic Markov equilibria.

"In this paper we study experimentally four remedies to overcome inefficiencies that arise from the incompleteness of contracts. These remedies are reciprocity, repeated game effects, social embeddedness, and incentive contracts. In our baseline treatment we find that reciprocity is a powerful contract enforcement device. A second experiment establishes that repeated game effects interact with reciprocity in a complementary way, i.e., efficiency is increased compared to our baseline. Adding social approval incentives does not contribute significantly to efficiency. Finally, we show that explicit incentive contracts may have perverse effects in the sense that they ""crowd out"" reciprocity and therefore reduce efficiency compared to the baseline. In our concluding section we discuss the relation of our findings to the recent literature on ""intrinsic motivation""."

We study behavior within a simple principal--agent experiment. Our design allows for a large class of linear contracts. Principals can offer any feasible combination of (negative) fixed wages and incentives in the form of return sharing. This great contractual flexibility allows us to study incentive compatibility simultaneously with issues of `fair sharing' and reciprocity, which were previously found to be important. We find a high degree of incentive-compatible behavior, but also `fair sharing' and reciprocity. In contrast to other incentive devices studied in the literature, the incentives are `reciprocity-compatible'. Principals recognize the agency problem and react accordingly.

Recently developed models of fairness can explain a wide variety of seemingly contradictory facts. The most controversial and yet unresolved issue in the modeling of fairness preferences concerns the behavioral relevance of fairness intentions. In this paper we provide clear and unambiguous experimental evidence for the behavioral relevance of fairness intentions. Our results indicate that the attribution of fairness intentions is important both in the domain of negatively reciprocal behavior and in the domain of positively reciprocal behavior. This means that reciprocal behavior cannot be fully captured by equity models that are exclusively based on preferences over the distribution of material payoffs. Models that take into account players' fairness intentions and distributional preferences are consistent with our data while models thatnfocus exclusively on intentions or on the distribution of material payoffs are not.

"At present, new EU-members have to fully accept the ""acquis communautaire"" even if their economic and institutional development differs drastically from the EU-average. In contrast, we propose that there should be the possibility of partial entry into the EU. East European Countries should have the option of specifically entering with respect to functions where they expect positive net benefits. In order to enable such partial entry, a new type of jurisdictions called FOCJ (Functional, Overlapping and Competing Jurisdictions) is proposed between the EU, the CEECs, and beyond. Such FOCJ allow for partial integration based on economic efficiency and democratic rules."
