We analyze the welfare impacts of price discrimination in a two-dimensional spatial differentiation model. Consumer information of varying qualities is available on one dimension which allows firms to price discriminate, and better information leads to more refined price discrimination. We find that as information quality improves, firms’ profits monotonically increase while consumer surplus an...

We estimate a generalized linear model to examine adult and teenage cigarette demand. Out analysis focuses on the extent to which excise taxes and regulations restricting smoking in public places affect cigarette consumption. The adult results indicate that the price elasticity of demand is unstable over time, ranging from 0.06 in 1970 to -0.23 in 1985. These estimates are lower than most found...
