Consider the seller’s problem of finding “optimal” prices for her (divisible) goods when faced with a set of consumers, given that she can only observe their purchased bundles at set prices, i.e., access to only revealed preferences (demand oracle). We study both social welfare and profit maximization under this setting, assuming concave valuation function of consumers and convex production cos...

Social services remain largely unresponsive to the values and needs of Latino families, who often need Spanish-language services. This article discusses access to linguistically appropriate services, not just as a culturally competent practice, but also as a civil rights issue. Spanish speakers have protection from discrimination in federally funded human services under Title VI of the Civil Ri...

For infinite societies, Fishburn (1970), Kirman and Sondermann (1972), and Armstrong (1980) gave a nonconstructive proof of the existence of a social welfare function satisfying Arrow’s conditions (Unanimity, Independence, and Nondictatorship). This paper improves on their results by (i) giving a concrete example of such a function, and (ii) showing how to compute, from a description of a profi...

In this paper we consider solutions which select from the core. For games with side payments with at least four players, it is well-known that no core-selection satisfies monotonicity for all coalitions; for the particular class of core-selections found by maximizing a social welfare function over the core, we investigate whether such solutions are monotone for a given coalition. It is shown th...

We introduce a new consistency condition for neutral social welfare functions, called hyperstability. A social welfare function α selects a complete weak order from a profile PN of linear orders over any finite set of alternatives, given N individuals. Each linear order P in PN generates a linear order over orders of alternatives,called hyper-preference, by means of a preference extension. Henc...

generally. j j Social Welfare, like Social Medicine, will fix its own standards, have its own objectives and develop its own techniques *n achieving the objectives. It cannot follow the Western standards, objectives and techniques. Asia in general and India in particular have an outlook different from the outlook of European cultures. It is different but not inferior by any means. The general i...

Formulation The framework consists of a set A of alternatives, or outcomes, and n players, or agents. Each player i has a valuation function vi : A → < that assigns a value to each possible alternative. This valuation function belongs to a domain Vi of all possible valuation functions. Let V = V1 × · · · × Vn, and V−i = ∏ j 6=i Vj. Observe that this generalizes the shortest path example of abov...

China’s social welfare reform since the mid-1980s has been characterized as incremental and fragmented in three dimensions—social insurance, privatization, and targeting. This paper attempts to explore the micro-foundation of China’s urban social welfare reform by examining the diverse social welfare preferences and the cleavages among societal groups. It argues that the diversity of the societ...

the purpose of this paper is to estimate the welfare cost of inflation in iran. we first use the long-horizon regression approach developed by fisher and seater (1993) to obtain an estimate of the inflation rate elasticity of money demand and then the baily’s consumer surplus approach to calculate the welfare cost function. the results show that reducing inflation rate from 40% to 0% increases ...

We study the problem of risk sharing within a household facing subjective uncertainty. A household shares uncertain prospects using a social welfare function. We characterize the social welfare functions such that the household is collectively less risk averse than each member, and satisfies the Pareto principle and an independence axiom. We single out the sum of certainty equivalents as the un...
