In this paper, we study a voluntary contribution mechanism withone-way communication. The relevance of one person’s words is assessedby assigning exogeniously the role of the ‘communicator’ to onegroup member. Contrary to the view that the mutual exchange ofpromises is necessary for the...

We enrich the choice task of responders in ultimatum games by allow- ing them to independently decide whether to collect what is offered to them and whether to destroy what the proposer demanded. Such a multidimensional response format intends to cast further light on the motives guiding...

In a two-person ï¬nitely repeated public goods experiment, we use intentions data to interpret individual behavior. Based on a random-utility model speciï¬cation, we develop a relationship between a player's beliefs about others' behavior and his contributions' plans, and use this...

A novel two-person "charity game" is used to experimentally investigate whether anticipation of help crowds out incentives to work, and therefore impulses to help. We distinguish two treatments differing in whether the causes of neediness are verifiable or not. Helping behavior does not vary...

We present an experiment designed to test the Modigliani-Miller theorem. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structures, we find that, in accordance with the theorem, participants well recognize changes in the systematic risk...

This paper aims to assess the empirical validity of the overall theoretical framework of other-regarding preferences. We focus on those preference axioms that are common to all the prominent theories of outcome-based other-regarding preferences. This common set of preference axioms leads to a...

This paper aims to experimentally investigate how individual willingness to pay for a lottery is affected by using a new way of representing of probabilistic ambiguity. Thus we can see how individual valuation reacts to different degrees of ambiguity probability information provided to subjects....

Experimental research on decision making under risk has until now always employed choicedata in order to evaluate the empirical performance of expected utility and the alternative nonexpectedutility theories. The present paper performs a similar analysis which relies on pricingdata instead of...
