Linear demand systems for differentiated goods: Overview and user’s guide

Capacity investment in electricity markets under supply and demand uncertainty

This paper examines the effect of cross-border shopping on grocery demand in Norway using monthly store*category sales data from Norway's largest grocery chain 2011-2016. The sensitivity of demand to foreign price is hump-shaped and greatest 30-60 minutes' driving distance from the closest foreign store. Combining continuous demand, fixed costs of cross-border shopping and linear transport costs `a la Hotelling we show how this hump-shape can arise through a combination of intensive and extensive margins of cross-border shopping. Our conclusions are further supported by novel survey evidence and cross-border traffic data.

On the microeconomic foundations of linear demand for differentiated products

The number of lawyers being produced at high cost combined with the relative lack of job options has recently created signicant concern. In order to partially explain this phenomenon, I propose a game of incomplete information modeling the strategic interaction between law schools and potential students. In equilibrium, the model predicts that because schools are more informed concerning their own quality than are students, lower quality schools will mimic higher quality schools with positive probability. This will result in both higher class sizes and tuition rates than under complete information at low quality schools. Using school level data, I give evidence corresponding to model predictions that a negative information shock concerning a school’s placement record results in a decrease in marginal valuation and therefore tuition costs for its students.
