Vote-trading is common practice in committees and group decision-making. Yet we know very little about its properties. Inspired by the similarity between the logic of sequential rounds of pairwise vote-trading and matching algorithms, we explore three central questions that have parallels in the matching literature: (1) Does a stable allocation of votes always exists? (2) Is it reachable throug...

The paper develops an economic–political model to explain why the convergence hypothesis fails even though good economic policies seem to be a sufficient condition for strong economic growth (Sachs, J., Warner, A., 1995a. Economic convergence and economic policies. NBER Working Paper No. 5039. National Bureau of Economic Research, Cambridge, MA.). The model has three variables: growth, policy, ...

Lobbying is studied in a series of signaling game experiments. Students as well as professional lobbyists are used as subjects. In contrast with some earlier studies, comparing students and professionals, we find significant differences in the behavior of the two subject pools. Professional subjects appear to behave more in line with the game–theoretic predictions, display a higher degree of se...

This study compares the representativeness of voters in the proportional electoral system with the situation under plurality rule. Representativeness is commonly measured by comparing parties’ received votes with their shares of seats in the Parliament; this implies that proportional rule should always better represent voters. A coalition within the Parliament, however, rules the country withou...

This paper studies the dominance-solvability (by iterated deletion of weakly dominated strategies) of plurality rule voting games. For any number of alternatives and at least four voters, we find sufficient conditions for the game to be dominance-solvable (DS) and not to be DS. These conditions can be stated in terms of only one aspect of the game, the largest proportion of voters who agree on ...

This paper studies the Markov perfect equilibrium outcomes of a dynamic game of electoral competition between two policy-motivated parties. I model incumbent policy persistence: parties commit to implement a policy for their full tenure in office, and hence in any election only the opposition party renews its platform. In equilibrium, parties alternate in power and policies converge to symmetri...

This paper proposes a model of two-party representative democracy on a singledimensional political space, in which voters choose their parties in order to influence the parties’ choices of representative. After two candidates are selected as the median of each party’s support group, Nature determines the candidates’ competence levels. Based on the candidates’ political positions and competence ...

We develop a model in which profits of media firms depend on their audience ratings, and maximizing profits may involve catering to a partisan audience by suppressing information that the partisan audience does not like hearing. While voters are rational, understand the nature of the news suppression bias and update appropriately, important information is lost through bias and can lead to elect...

We consider a model in which voters over time receive more information about their preferences concerning an irreversible social decision. Voters can either implement the project in the first period, or they can postpone the decision to the second period. We analyze the effects of different majority rules. Individual first period voting behavior may become “less conservative” under supermajorit...

We analyze a model in which voters learn over time their preferences regarding an irreversible social decision. Voters can either implement the project in the first period, or they can postpone the decision to the second period. We analyze the effects of different majority rules. We show that individual first period voting behavior may become “less conservative” under supermajority rules, and t...
