Weighted voting games provide a popular model of decision making in multiagent systems. Such games are described by a set of players, a list of players’ weights, and a quota; a coalition of the players is said to be winning if the total weight of its members meets or exceeds the quota. The power of a player in such games is traditionally identified with her Shapley– Shubik index or her Banzhaf ...

150 words) Gender quotas have been adopted in over a hundred countries in an effort to address gender disparities in national legislatures. Yet, the determinants of citizen support for gender quota policies remain largely understudied. We develop a theory that emphasizes the impact of institutional performance and political values to explain citizen support for gender quotas and how these two f...

Gender quotas have been adopted in over a hundred countries in an effort to address gender disparities in national legislatures. Yet the determinants of citizen support for gender quota policies remain largely understudied. We develop a theory that emphasizes the impact of institutional performance and political values to explain citizen support for gender quotas and how these two factors diffe...

The set Gn of all n-person games 1 may be considered a convex subset of a euclidean space; Gn has dimension 2 n — n — 2. Although it has not been proved that all games possess a solution, large classes of solvable games have been discovered. In [2], Shapley defined a certain class of solvable games—the quota games—and showed that from the point of view of dimension, the set Qn of all ^-person q...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country’s relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare subject to being implementable by Perfect Bayesian equilibria. With complete information, the optimal q...

This paper incorporates the milk quota system into technical efficiency analysis of dairy farms in England and Wales. Our approach accounts for milk quota trade, allowing an investigation of the relationship between the way in which milk quota market is used by farmers and technical efficiency. In addition, several explanatory variables for inefficiency were used. Results obtained from a Bayesi...

Given that the Common Agricultural Policy (CAP) of the European Union has imposed milk marketing quota on producers, the fact that they are tradeable in the UK increases economic efficiency. Nevertheless, significant inefficiencies remain. Modelling work reported here suggests that significantly more quota needed to be transferred from less to more efficient producers in 1996/97 for industry ef...

We study multiple-unit asymmetric procurement auctions wherein sellers from two classes draw costs from different distributions. When sellers are asymmetric, a cost-minimizing buyer discriminates among classes of sellers to enhance competition [1]. Establishing a quota—a limit on the number of offers that can be accepted from any one class—discriminates simply and effectively. The quota increas...

Price-Discrimination bucket pricing (PDBP) is a unique price format that usually involves monthly subscription fees and instantaneous quotas. We propose an empirical model in which consumers make dynamic purchase decisions under consumption uncertainty, accounting for the constraints imposed by the instantaneous quota. Applying the model to an online DVD rental data, we find that (1) consumers ...

The Droop quota is traditionally rounded up to the next integer. It has been pointed out by Lundell and Hill that this can have negative consequences. We give two further examples of such consequences, showing that rounding the Droop quota can cause violations of monotonicity and proportionality. This supports the conclusion by Lundell and Hill that it is better to use the exact Droop quota wit...
