Making the World a better Place: Experimental evidencefrom the generosity Game

Güth, Werner; Levati, Maria Vittoria; Ploner, Matteo - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2009

We study ultimatum and dictator experiments where the first moverchooses the amount of money to be distributed between the playerswithin a given interval, knowing that her own share is fixed. Thus, thefirst mover is faced with scarcity, but not with the typical trade-off betweenher own and the...

Testing the Modigliani-Miller theorem directly in the lab

Levati, Maria Vittoria; Qiu, Jianying; Mahagaonkar, … - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2011

We present an experiment designed to test the Modigliani-Miller theorem. Applyinga general equilibrium approach and not …, participantswell recognize changes in the systematic risk of equity associated with increasingleverage and, accordingly, demand higher … rate of return. Yet, this adjustment is notperfect: subjects underestimate the systematic risk of low-leveraged equity …

Scenario-Based Satisficing in Saving:A Theoretical and Experimental Analysis

Güth, Werner; Levati, Maria Vittoria; Ploner, Matteo - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2007

Contrary to the models of deterministic life cycle saving, we take itfor granted that uncertainty of one's future is the essential problem ofsaving decisions. However, unlike the stochastic life cycle models, we capturethis crucial uncertainty by a non-Bayesian scenario-based...

Indirect Reciprocity in Cyclical Networks- An Experimental Study

Greiner, Ben; Levati, Maria Vittoria - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2003

A cyclical network of indirect reciprocity is derived organizing 3- or6-person groups into rings of social interaction where the first individualcan help the second, the second the third, and so on till the last, who inreturn can help the first. Mutual cooperation is triggered by assuming...

Context and Interpretation in Laboratory Experiments:The Case of Reciprocity

Levati, Maria Vittoria; Miettinen, Topi; Rai, Birendra K. - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2010

The existing literature acknowledges that a mismatch between the experimenter'sand the subjects' models of an experimental task can adversely aect the interpretation ofdata from laboratory experiments. We discuss why the two common experimental designs(between-subjects and within-subjects) used...

An Application of the English Clock MarketMechanism to Public Goods Games

Levati, Maria Vittoria; Neugebauer, Tibor - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2001

We conducted a laboratory study with a public goods game in which contributions are notsubmitted all at once but incrementally as coordinated in real time by a clock. Individualspress a button as soon as the clock equals their willingness to contribute. This publicgoods institution exploits the...
