We study the efect of price variations over time and across space on search intensity and search time by consumers in retail markets for diesel in France. The main contribution of the paper is that existing work in industrial organisation in this area has already studied the efect of such variability on the frst measure of search but not on the second one. Using novel data from daily consultation measures and price information from a government-run website, we fnd that price dispersion across space increases search activity and the amount of time allocated to search. Furthermore, while contemporaneous price changes do not appear to infuence the number of visits and time per visit to the website, several coeffcients on past price changes are positive and statistically diferent from zero. Our results thus suggest that price dispersion and price variability play a role in inducing search by current and potential customers.
