We consider a pure exchange economy under uncertainty in which the traders have the non-partition structure of information. They willing to trade the amounts of state-contingent commodities and they know their own expectations. Common knowledge of these conditions among all the traders can...

Arrow's celebrated theorem of social choice shows that the aggregation of individual preferences into a social ordering cannot make the ranking of any pair of alternatives depend only on individual preferences over that pair, unless the fundamental weak Pareto and nondictatorship principles are...

Property rights regimes determine a relationship between rights-holder and non rights-holder. It determines who takes responsibility and/or bears costs for environmental restoration. We analyze In-Stream Water Rights System introduced in Oregon in 1987. Where In-stream water right means the...

In a standard framework of choice theory, we formulate two contrasting principles for social choice under the efficiency-equity trade-off. The equity-first principle states that we should select from equitable allocations if any, but if the equity criterion is not at all effective for selection...

Nonlinear drift models of the short-rate are estimated using data on the short-end of the term structure, where the cross-sectional relation is obtained by an analytical approximation. We find that (i) nonlinear physical drift is not implied unless it is strongly affected by cross-sectional...

This paper examines the determinants of intergenerational correlation of education in rural China by using a data from a large survey of households. Three generations who completed education during the period from pre-1949 to the beginning of the 2000s are included. The focus is on the influence...

The theory of fair allocation is often favourably contrasted with the social choice theory in the search for escape routes from Arrow's impossibility theorem. Its success is commonly attributed to the fact that it is modest in its goal vis-`a-vis social choice theory, since it does not aspire...

Let us consider a pure exchange economy under non-partitional information where the traders are assumed to have a reflexive and transitive information structure and to have strictly monotone preferences. We show the no speculation theorem: If the initial endowment is ex-ante Pareto optimal then...
