Social choice theory or social choice is a theoretical framework for analysis of combining individual preferences, interests, or welfares to reach a collective decision or social welfare in some sense. [ 1 ] A non-theoretical example of a collective decision is enacting a law or set of laws under a constitution . Social choice theory dates from Condorcet 's formulation of the voting paradox . Kenneth Arrow 's Social Choice and Individual Values (1951) and Arrow's impossibility theorem in it are generally acknowledged as the basis of the modern social choice theory. [ 1 ] Social choice blends elements of welfare economics and voting theory . It is methodologically individualistic , in that it aggregates preferences and behaviors of individual members of society. http://en.wikipedia.org/wiki/Social_choice_theory

Singer–Prebisch thesis

The Singer–Prebisch thesis (also Prebisch–Singer thesis , PST , or Prebisch–Singer hypothesis ) postulates that terms of trade , between primary products and manufactured goods, deteriorate in time. In 1950, the economists Raúl Prebisch and Hans Singer independently developed the thesis that countries that export commodities ( developing countries ) in time would import fewer manufactured goods relative to a given level of exports. However, during the 2000s commodities boom , the terms of trade of most developing countries improved while east Asia (with much of its export to be manufactured goods) has deteriorated terms of trade.
