Risk may induce precautionary saving but it can also reduce saving. The theoretical literature recognizes both possibilities, but favors a positive effect (both for developed and developing countries); the empirical literature is divided, reporting (small) positive effects for developed...

Many empirical studies on intertemporal choice report preference reversals in the sensethat a preference between a small reward to be received soon and a larger reward to bereceived later reverses as both rewards are equally delayed. Such preference reversals arecommonly interpreted as...

We propose a novel utility representation for preferences over risky timed outcomes. The weighted temporal utility model generalizes many well known utility functions for intertemporal decision making under risk. A decision maker with a weighted temporal utility function can have time consistent...

From the viewpoint of the independence axiom of expected utility theory, an interesting empirical dynamic choice problem involves the presence of a “global risk,” that is, a chance of losing everything whichever safe or risky option is chosen. In this experimental study, participants have to...

This paper investigates an implication of the self-serving bias for reciprocalresponses. It is hypothesized that negative intentionality matters more thanpositive intentionality for reciprocating individuals with a self-servingattributional style. Experimental evidence obtained in the hot...

We consider cooperative games with transferable utility (TU-games), in which we allow for a social structure on the set of players. The social structure is utilized to refine the core of the game. For every coalition the relative strength of a player within that coalition is induced by the...

This article analyzes under which conditions a manager can motivate a junior worker by verbal communication, and explains why communication is often tied up with organizational choices as job enlargement and collaboration. Our model has two important features. First, the manager has more...

This paper associates a strategic n-person game with a given transferable utility game and studies its Nash equilibria. Strict equilibria in this model characterize those divisions of social surplus that can become conventions in the sense of Young (1993). It is shown that even in relatively...

Many economic and social situations can be represented by a digraph. Both axiomatic and iterativemethods to determine the strength or power of all the nodes in a digraph have been proposed inthe literature. We propose a new method, where the power of a node is determined by both thenumber of its...

This paper is an effort to convince the reader that using a stochastic stage game in a repeated setting - rather than a deterministic one - comes with many advantages. The first is that as a game it is more realistic to assume that payoffs in future games are uncertain. The second is that it...
