Many important decisions are taken according to weighted majority rule. Power indices predict that enlargement of the voting body may affect the balance of power between the original members even if their number of votes and the decision rule remain constant. Some of the existing voters may...

We investigate the effects of information feedback in rent-seeking games with two different contest structures. In the deterministic contest a contestant receives a share of the rent equal to her share of rent-seeking expenditures, while in the stochastic contest a contestant wins the entire...

We investigate the role of information feedback in rent-seeking games with two different contest structures. In the stochastic contest a contestant wins the entire rent with probability equal to her share of rent-seeking expenditures; in the deterministic contest she receives a share of the rent...

Power indices suggest that adding new members to a voting body may affect the balance of power between the original members even if their number of votes and the decision rule remain constant. Some of the original members may actually gain, a phenomenon known as the paradox of new members. We...

Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of group diversity on group risk taking. I measure econometrically the effects of various aspects of subjects' diversity: nationality, language, university degree and gender. I find...

We report evidence from public goods experiments with and without punishment which we conducted in Russia with 566 urban and rural participants of young and mature age cohorts. Russia is interesting for studying voluntary cooperation because of its long history of collectivism, and a huge...
