the main objective of this paper is to examine the impact of economic growth on coefficient of cardinal welfare in iran’s economy. hence, we employ the bayesian approach and the estimation of forward and backward density functions in order to measure the effect of economic growth spillovers on the social welfare. the paper has applied the gibbs sampling algorithm which is a rigorous tool for fo...

This paper is addressed to comparing inequality in distributions of two or more variables. Based on an extended version of the Lorenz Curve criterion, a theorem is proved which says that total income is always less unequally distributed than the most unequally distributed income component. As an illustration, a decomposition of the coëfficiënt of variation of total income is given in terms of c...

Majority voting and social evaluation functions are the main alternatives proposed in the literature for aggregatingindividual preferences. Despite these being very different, this papershows that the ranking of income distributions, symmetric under the same transformation, by S-Gini consistent social evaluation functions and majority voting coincide if and only if the inequality index under co...

A number of studies have shown that inequality is increasing in the rural and urban areas of Nigeria and this can be linked to the growing dimension of poverty. The study focused on analysing inequality and welfare status of rural households in Ekiti State, Nigeria. The result presented was based on primary data collected from a random sample of 240 households selected from four rural communiti...

In this paper we examine how increases in intertemporal price uncertainty affect the welfare of a consumer. In the preference structure of the consumer the coefficient of relative risk aversion and the elasticity of intertemporal substitution (EIS) are parametrically independent. We find that under empirically plausible circumstances, for each given degree of risk aversion an increase in price ...

The debate over various definitions of sustainability has for the most part been conducted within the framework of traditional welfare economics. Discussion has centered on technical issues imbedded within the functional forms of various optimization models, especially the coefficient of the elasticity of substitution and the social discount rate. Two more basic problems are: (1) intractable th...

The study aimed to verify a hypothesis that a sense of fulfillment in student life and perceived stress in training in the facilities could affect vocational identity among social welfare university students, in order to acquire implications for enhancing the vocational consciousness. A questionnaire survey was conducted with 388 thirdand fourth-year students of training course for certified so...

Since Soltow (1960) first addressed the question of the Gini coefficient decomposition by population subgroups (hereinafter referred to as decomposition), there are more than a dozen different decompositions available in the literature. Whether the Gini coefficient is decomposable and, furthermore, whether the decomposition practices are arbitrary are debated in the literature, since there is n...

We study the problem of allocatingm items to n agents subject to maximizing the Nash social welfare (NSW) objective. We write a novel convex programming relaxation for this problem, and we show that a simple randomized rounding algorithm gives a 1/e approximation factor of the objective. Our main technical contribution is an extension of Gurvits’s lower bound on the coefficient of the square-fr...
