In Binary Threshold Public Good (BTPG) games players contribute or not to the production of a public good which is produced if and only if there are "enough" contributors. There is a plethora of equilibria in BTPG games. We experimentally test general theoretical attributes of equilibria and...

In a laboratory experiment we investigate inter-generational concerns and myopia in a dynamic Public Good game. Groups of four played a 15-period game where they could either invest in a green sector or in a more profitable brown sector that builds a pollution stock. We find that subjects are...

The main goal of collective punishment (CP) is the deterrence of future "wrong-doing" by freedom fighters or terrorists, protesters against an authoritative government, polluters, students playing pranks on their teacher, football teams lacking enthusiasm, or soldiers showing cowardice to the...

In Binary Threshold Public Good (BTPG) games, n players have binary choices: cooperation or non-cooperation. If at least k players cooperate, a public good is produced. The case k = n is the Stag Hunt game with the two pure strategy equilibria E1 (all players cooperate) and E0 (no player...

Most voting models in the literature neglect abstention, but is such a simplification justified? I investigate this question in a model with outside pressure on voters. For sequential voting (e.g., roll call votes), with and without an abstention option, there is a unique subgame perfect...

When including outside pressure on voters as individual costs, sequential voting (as in roll call votes) is theoretically preferable to simultaneous voting (as in recorded ballots). Under complete information, sequential voting has a unique subgame perfect equilibrium with a simple equilibrium...

In random voting, the committee chair, whose vote decides in the case of a draw, is more often decisive than ordinary voters. Therefore, in the power indices literature, the committee chair is said to be more powerful. Players with a veto right are even more powerful still. Similarly, the...

In the Solidarity game lucky winners of a lottery can transfer part of their income to unlucky losers. Will losers get smaller transfers if they can be assumed to be responsible for their zero income because they have chosen riskier lotteries? Or will risk-lovers and riskaverters favor those who...
