Poverty measures in developing countries often ignore the distribution of resources within families and the gains from joint consumption. In this paper, we estimate the allocation process and adult economies of scale in households from Côte d'Ivoire using a collective model of household...

This paper deals with real estate portfolio optimization when investors are risk averse. In this framework, we determine several types of optimal times to sell a diversified real estate and analyze their properties. The optimization problem corresponds to the maximization of a concave utility...

In this paper, we compare five well-known methods of apportionment, the ones by Adams, Dean, Hill, Webster and Jefferson. The criteria used for this comparison is the minimization of a distance between a power vector and a population vector. The power is measured with the well-known Banzhaf...

The purpose of this paper is to present a structural specification of the Shapley- Shubik and Banzhaf power indices in a weighted voting rule. We compare them in term of the cardinality of the sets of power vectors (PV). This is done in different situations where the quota or the number of seats...

We provide possibility results on the aggregation of beliefs and tastes for Monotone, Bernoullian and Archimedian preferences of Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci, and Siniscalchi (2011). We propose a new axiom, Unambiguous Pareto Dominance, which requires that if the...

This paper quantifes the welfare gains from intra-form trade. We propose a model where rms have access to competing market strategies: export and multinational production. Due to technolog- ical appropriability issues, foreign affiliates import an intermediate input from the home headquarters....

We show that if the statistical distribution of utility functions in a population satisfies a certain condition, then a Condorcet winner will not only exist, but will also maximize the utilitarian social welfare function. We also show that, if people's utility functions are generated according...

Given a sufficiently large population satisfying certain statistical regularities, we show that it is often possible to accurately estimate the utilitarian social welfare func- tion and identify the welfare-maximizing social alternative, even if we only have very noisy data about individual...

Given a large enough population of voters whose utility functions satisfy certain statistical regularities, we show that voting rules such as the Borda rule, approval voting, and evaluative voting have a very high probability of selecting the social alternative which maximizes the utilitarian...

East Asian and Latin American economies present opposite exchange rate electoral cycles: exchange rates tend to be more depreciated before and appreciated after elections among East Asian economies, while the opposite is true in Latin America. We propose a explanation for these empirical...
