We model a general choice environment via probabilistic choice correspondences, with (possibly)incomplete domain and infinite universal set of alternatives. We offer a consistency restrictionregarding choice when the feasible set contracts. This condition, ‘contraction consistency’,...

We unify and expand the theory of consumer’s behavior, based on Samuelson’s Weak Axiomof Revealed Preference, to permit simultaneously both random choice and non-singletonchoice sets. We provide a consistency postulate for demand behavior when such behavior isrepresented in terms of a...

We explore the relation between two 'rationality conditions' for stochastic choicebehaviour: regularity and the weak axiom of stochastic revealed preference (WASRP). We show thatWASRP implies regularity, but the converse is not true. We identify a restriction on the domain ofthe stochastic...

We generalize the stochastic revealed preference approach to consumers’ behavior introduced byBandyopadhyay, Dasgupta and Pattanaik (1999). We identify a restriction on stochastic demandbehavior that we term “Stochastic Substitutability” (SS)...

We test for mean reversion in real exchange rates using data from five countries, four of whichhave experienced episodes of high inflation. We use monthly data for Argentina, Brazil, Chile,Colombia and Israel from 1972 to 1993 and find that in all cases except Brazil a stochastic unitroot model...

This paper analyzes the problem of deriving the law of supply from plausible restrictions onobserved input-output choices of a competitive firm, when the firm makes random input-outputdecisions. It models such random production behavior in terms of a stochastic supply function,and introduces a...
