    Preference for Variety

    We consider a decision maker who enjoys choosing from a varied set of alternatives. Building on behavioral evidence, we propose testable axioms which characterize preference for variety, and provide a representation theorem. We go on to illustrate the potential effects of preference for variety in a model of retailing. Consumer welfare may be decreasing in the competitiveness of the retailing sector as competition eliminates the scope for retailers to offer variety. Mainstream consumers with a preference for variety and consumers with eccentric tastes enjoy a symbiotic relationship. Competition over mainstream consumers makes retailers offer more exotic goods, while eccentric consumers subsidize their carrying costs.Preferences, variety, representation theorem, retail, competition.

    AbstractIn this paper, we investigate the rate of convergence for general d-dimensional stochastic approximation procedures and present an explicit expression for the asymptotic bounds in the law of the iterated logarithm
