Abstract：
This paper measures the response to new competition using a novel longitudinal dataset of restaurant menus in New York City. The detailed information in restaurant menus allows for precise measurement of price and product changes for incumbent restaurants responding to entry. We address the endogeneity of location choice by matching "treated" incumbent restaurants facing competition from a new entrant with a "control" group of incumbent restaurants that have similar menus and location characteristics but no new competition. We are able to closely match restaurants by converting differences in menu text into a pairwise measure of the distance between restaurants in product characteristics space. Our preliminary results indicate that restaurants facing additional competition reduce their prices; this reduction appears to be concentrated on the intensive margin. We seek to provide some of the first evidence on the response to competition in markets with substantial product differentiation, many firms, and rapid turnover.
