For many goods (such as experience goods or addictive goods), consumers’ preferences may change over time. In this paper, we examine a monopolist’s optimal pricing schedule when current consumption can affect a consumer’s valuation in the future and valuations are unobservable. We assume...

Wage inequality in the United States has grown substantially in the past two decades. Standard supply-demand analysis in the empirics of inequality (e.g.Katz and Murphy (1992)) indicates that we may attribute some of this trend to an outward shift in the demand for high skilled labor. In this...
