Does religious commitment have a common political impact across national frontiers? To date, that question has been explored empirically only for Roman Catholics, who might be expected to behave similarly because of centralizing resources in their tradition. This article explores the extent of transnational political attitudes among Jews in the United States and Israel, two groups with less cen...

Using a new representation theorem for additive cost sharing methods as sums of path methods, we show that many of the standard additive cost sharing methods (Aumann-Shapley, Shapley Shubik, and Serial Cost) are consistent. These results follow directly from a simple suucient condition for consistency: being generated by associative paths, which can be used to show consistency for many other me...

In this paper we show that panel estimates of tenure speci…c sensitivity to the business cycle of wages is subject to serious pitfalls. Three canonical variates used in the literature the minimum unemployment rate during a worker’s time at the …rm(minu), the unemployment rate at the start of her tenure(Su) and the current unemployment rate interacted with a new hire dummy( u) can all be signi…c...

We resolve redundancies in the characterizations of the Banzhaf value suggested by Haller (1994, Int J Game Theory 23, 261–281) and Malawski (2002, Int J Game Theory 31:47–67). In particular, we show that the collusion properties employed by them are equivalent. Combined with the dummy player axiom, any of the collusion properties has strong symmetry implications whenever the cardinality of the...

This paper studies power indices based on average representations of a weighted game. If restricted to account for the lack of power of dummy voters, average representations become coherent measures of voting power, with power distributions being proportional to the distribution of weights in the average representation. This makes these indices representationcompatible, a property not fulfilled...

We present two left-to-right integer recodings which can be used to perform scalar multiplication with a fixed sequence of operations. These recodings make it possible to have a simple power analysis resistant implementation of a group-based cryptosystem without using unified formulas or introducing dummy operations. This approach is very useful for groups in which the doubling step are less ex...

This paper investigates the impact of hedging activities on U.S. export pricing. A theoretical framework of export pricing model with a hedging component was derived to test the hypothesis via exchange rate pass-through. The hypothesis is that a firm with a high (low) hedging engagement would have a low (normal) degree of exchange rate pass-through, ceteris paribus. Two measurements of the hedg...

We present an axiomatic characterization of the Owen-Shapley spatial power index for the case where issues are elements of two-dimensional space. This characterization employs a version of the transfer condition, which enables us to unravel a spatial game into spatial games connected to unanimity games. The other axioms are spatial versions of anonymity and dummy, and two conditions concerned p...

This paper presents a data driven approach that enables one to obtain a measure of comparability between-groups in the presence of observational data. The main idea lies in the use of the general framework of conditional multiple correspondences analysis as a tool for investigating the dependence relationship between a set of observable categorical covariates X and an assignment-to-treatment in...

In this paper I focus on the effect of informal networks on individuals’ job search and earnings. In the empirical analysis, conducted on data drawn from the 1991 and 1993 Bank of Italy Survey of Household Income and Wealth, I show that while seeking work through informal networks (referrals by friends, relatives, or acquaintances to potential employers) increases the probability of receiving j...
