In this paper, we provide an axiomatic characterization of social welfare functions for uncertain incomes. Our most general result is that a small number of reasonable assumptions regarding welfare orderings under uncertainty rule out pure ex ante as well as pure ex post evaluations. Any social welfare function that satisfies these axioms should lie strictly between the ex ante and the ex post ...

introduction social development is a phenomenon having close relationship with ways and how the people live in a society. the main goal of  social development is to upgrade the levels of general livings’ status by creating preferred conditions based on accepted values.focuses must be on: reducing poverty and improving the qualities of nutrition, hygiene, housing, occupation, education and fruit...

We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on the assumption that the population is finite. For infinite populations, there exist nondictatorial social welfare functions satisfying Arrow’s axioms and they can be described by their corresponding collections of decisive coalit...

Social trust is the main component of social capital. In this regard, subjective welfare is one of the important aspects of human life. Based on the human needs growth, it must be considered both objective and subjective aspect of welfare. The present study tries to use survey method and collect data by cluster sampling among 381 persons of 20-29 Youth in Tehran as the sample of this research. ...

This paper shows the macroeconomic and welfare implications of an aging population in the United States, using a heterogeneous-agent overlapping-generations model with uninsurable idiosyncratic working ability shocks and mortality shocks. The model uses three population projections in Social Security Administration (2003), and generates economies as equilibrium transition paths from 1961 to 220...

Following the failure of economic development and growth policies and dissatisfactions resulting from applying these policies, related discussions to life satisfaction was proposed among various experts. In their opinion, different factors can be effectual on life satisfaction. One of the most important factors is social welfare. This study is a social survey and it has used questionnaire for c...

Following Sethuraman, Teo and Vohra ((2003), (2006)), we apply integer programming tools to the analysis of fundamental issues in social choice theory. We generalize Sethuraman et al.’s approach specifying integer programs in which variables are allowed to assume values in the set {0, 12 , 1}. We show that there exists a one-to-one correspondence between the solutions of an integer program defi...
