Price Dispersion Then and Now: Evidence from Retail and E-tail Markets

چکیده
This paper uses two datasets to examine price dispersion spanning a 24-year period. The first dataset permits us to compare levels of retail price dispersion in 1976 and 2000, while the second allows for a comparison of retail dispersion in 1976 with dispersion in e-tail markets in 2000. Our results indicate that price dispersion in 2000 for both retail and e-tail markets is comparable to that observed in 1976 retail markets. This suggests that, for the products in our sample, the Information Age has done little to reduce price dispersion in retail or e-tail markets.

متن کاملA Theory of Bidding Dynamics and Deadlines in Online Retail∗
We present an equilibrium search model that parsimoniously rationalizes the use of auctions as a sales mechanism for new-in-box goods—a frequent occurrence in online retail markets—and analyze whether the existence of these auctions is welfare enhancing relative to a market consisting only of posted prices. Buyers have a deadline by which the good must be purchased, and sellers choose between a...
