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...

However, behavioral evidence is rare. This paper provides an empirical analysis on how individuals’ relative income position affectsntheir performance. Using a unique data set for 1114 soccer...

Active Decisions and Pro-social Behavior: A Field Experiment on Blood Donation
"In this paper, we propose a decision framework where people are individually asked to either actively consent or dissent to some pro-social behavior. We hypothesize that confronting individuals with the choice of engaging in a specific pro-social behavior contributes to the formation of issue-specific altruistic preferences while simultaneouslyninvolving a commitment. The...

Portfolio Choice with Loss Aversion, Asymmetric Risk-Taking Behavior and Segregation of Riskless Opportunities
In this paper we present a two period model, where the agent'snpreferences are described by prospect theory as proposed by Kahneman and Tversky. We solve for the agent's portfolio decision. Our findings are that the changes in portfolio weights depend crucially on the reference point and the ratio between the reference point and the current wealth, and thus only indirectly...

Tax Evasion in Switzerland: The Roles of Deterrence and Tax Morale
The traditional economic approach to tax evasion does not appear to be particularly successful in explaining the extent of tax compliance. We argue instead that a psychological tax contractnwhich establishes a fiscal exchange between the state and the citizens shapes tax compliance to a large extent. In that respect, a case study of Switzerland is useful because the small size of the...

Blood and Ink! The Common-Interest-GameBetween Terrorists and the Media
It has often been pointed out in the literature that a symbiotic relationship exists betweennterrorist groups and the media. As yet, however, no formal model has been built based on thisnissue and only very little empirical research has been done in this field. The presentncontribution builds a simple game theoretic model, focussing on the social interactionsnbetween terrorists and...

Correlated Risks: A Conflict of Interest Between Insurers and Consumers and Its Resolution
This contribution starts out by noting a conflict of interest between consumers and insurers. Consumers face positive correlation in their assets (health, wealth, wisdom, i.e. skills), causing them to demand a great deal of insurance coverage. Insurers on the other hand eschew positively correlated risks. It can be shown that insurance contributes to a reduction of their asset...

The case for risk-based premiums in public health insurance
Uniform, risk-independent insurance premiums are accepted as part of ‘managed competition’ in health care. However, they are not compatible with optimality of health insurance contracts in the presence of both ex ante and ex post moral hazard. They have adverse effects on insurer behaviour even if risk adjustment is taken into account. Risk-based premiums combined with means-tested,...

Unique equilibra in the rubinstein bargaining model when the payoff set is nonconvex
I give necessary and sufficient conditions on the payoff set that guarantee uniqueness of the equilibrium in the Rubinstein bargaining model. The conditions encompass a class of non-convex or disconnected payoff sets with discontinuous Pareto frontiers. Roughly speaking, the equilibrium is unique if the objective function of the corresponding Nash-bargaining game has a unique maximum...

The Apple Falls Increasingly Far: Parent-Child Correlation in Schooling and the Growth of Post-Secondary Education in Switzerland
In this paper, we analyze the completed highest education degree of two birth cohorts (1934-1943 and 1964-1973) in Switzerland, using data from the 1999 wave of the Swiss Household Panel. As expected, the fraction of tertiary graduates has increased over time, for women more so than for men. Also, the educational attainment depends strongly on the educational attainment of parents....
