In a simple single commodity certainty setting with changing tastes, a consumer's consumption plan can be obtained using naive or sophisticated choice. Although in general these solutions diverge, they agree in the special case where the changing tastes are represented by discounted logarithmic...

Many consumers care about climate change and other externalities associated with their purchases. We analyze the behavior and market effects of such "socially responsible consumers" in three parts. First, we develop a flexible theoretical framework to study competitive equilibria with rational...

Policy analysis frequently requires estimates of aggregate (or mean) consumer elasticities. However, estimates are often made incorrectly, based on elasticity calculations at mean income. We provide in this paper an overall integrated analytical framework that encompasses these biases and...

“Buy Now, Pay Later” (BNPL) and other forms of consumer credit create a wedge between consumption and payments. We introduce this wedge into a standard consumption-based asset pricing model (CCAPM). In equilibrium, the pricing kernel equals the marginal utility of consumption divided by the...

US consumers currently eat less fruits and vegetables (FV) than recommended by dietary guidelines. Inadequate FV consumption exists alongside rapid growth in demand for organic FV. Since the viable production area of FV is finite, organic and conventional FV are linked in production while...

This paper presents a geographical theory of location and interregional trade. Location is treated as an endogenous variable by firms, consumers and perfectly mobile workers in a two-sector economy. Space plays a central role owing to transportation costs, market access, and distance from...
