Agents are subject to liquidity shocks which can be partially insured in a secured money market, ornat a standing facility operated by the central bank. We show that it is optimal to have a strictly positive interest rate corridor and that a shift of the…

It first examines the competitive effects and costs of introducing MNP. Next, it discusses how to charge for MNP. It argues that a price cap regime starting from the average cost of porting is likely to provide appropriate incentives. Finally, it…

Probleme der Finanzierung sind für die Marktdiffusion innovativer Energietechnologien ebenso wichtig wie ihre technischen Eigenschaften oder der erwartete Nutzen aus der Technologieanwendung. Welche Rolle spielt dabei die Eigentümerstruktur des Innovators? Welchen Einfluss hat die Finanzierungsform des Investitionsvorhabens—und damit das finanzielle Risiko—auf die Attraktivität einer…

Evaluitis - Eine Neue Krankheit

“Evaluitis” - i.e. ex post assessments of organizations and persons - has become a rapidly spreading disease. In addition to the well-known costs imposed on evaluees and evaluators, additional significant costs are commonly disregarded: incentives are distorted, ossification is induced and the decision approach is wrongly conceived. As a result, evaluations are used too often and too…

Pareto-Improving Social Security Reform When Financial Markets Are Incomplete!?

This paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a Pareto improvement. When returns to capital and wages are imperfectly correlated a system that endows retired households with claims to labor income enhances the sharing of aggregate risk between…

People feel badly when they deviate from anbinding norm, and the less other players deviate, the more badly they feel.nFurther, people anger at transgressors and get pleasure from punishing them. Inthen study how social norms and emotions affect cooperation, coordination,…

We show that these results are partly based on a strong subject poolneffect. The participants of the E&S…

Foreign Direct Investment and R&D offshoring

We analyze a two-country model of Foreign Direct Investment (FDI). Two firms, each of which is originally situated in only one of the two countries, first decide whether to build a plant in the foreign country. Then, they decide whether to relocate R&D activities. Finally, they engage in product-market competition. Our main points are: first, FDI liberalization causes a…

Harmonic sequence paradox

Informal evidence suggests that individuals are willing to pay only a finite and, typically, very low price for a specific lottery that converges to an infinite payment with probability one. The established decision theories (expected value, expected utility theory, cumulative prospect theory) cannot satisfactorily explain this low willingness to pay. The presented paradox…

Models and Anti-Models: The Structure of Payoff-Dependent Social Learning

We conducted an experiment to describe how social learners use information about the relation between payoffs and behavior. Players chose between twontechnologies repeatedly. Payoffs were random, but one technology was better because its expected payoff was higher. Players were divided into two groups:n1) individual learners who knew their realized payoffs after each choice andn2)…

The Effect of Income on Positive and Negative Subjective Well-Being

Increasing evidence from the empirical economic and psychological literature suggests that positive and negative well-being are more than opposite ends of the same phenomenon. Two separate measures of the dependent variable may be needed when analyzing the determinants of subjective well-being. We argue that this conclusion reflects in part the use of too restrictive econometric…

Violations of betweenness or random errors?

A betweenness axiom states that if A and B are equally good then a mixture of A and B is equally good as well. This note demonstrates that the violations of the betweenness axiom documented in several experimental studies can be alternatively attributed to the effect of random errors.

The as-is journal review process: Let authors own their ideas

Recently, the problems associated with the existing journal review processnaroused discussions from seasoned management researchers, who have also made useful suggestions for improving the process. To complement these suggestions, we propose a more radical change: a manuscript should be reviewed on an “as is”nbasis and its fate be determined in one round of review. The as-is review…

Tax Morale and Conditional Cooperation

Why so many people pay their taxes, although fines and audit probability are low, has become a central question in the tax compliance literature. A homo economicus, with a more refined motivation structure, helps us to shed light on this puzzle. This paper provides empirical evidence for the relevance of conditional cooperation, using survey data from 30 West and East European…

This chapter discusses the role of environmental morale and environmental motivation in individual behavior from the point of view of economics and psychology. It deals with the fundamental public good problem, and presents empirical (laboratory and field) evidence on how the cooperation problem can be overcome. Four different theoretical approaches are distinguished according to how…

The effect of sunk costs on the outcome of alternating-offers bargaining between inequity-averse agents

When investments are specific to a relationship and contracting possibilities are incomplete, the efficiency of a joint venture may be severely impaired by ex-post opportunistic and hold-up type behavior. How is the logic of this argument affected by inequity aversion? In this paper I show that incentives to invest are stronger with inequity aversion because a higher investment by an…
