Price comparison websites, where consumers can compare prices at a search cost that is close to zero, have become increasingly common around the world. Using daily information on prices, click-throughs, and the number of retailers for a sample of consumer electronics and durable goods over a...

In product markets, there exists substantial dispersion in prices for transactions of physically identical goods, and incumbent sellers sell at higher prices than entrants. This study develops a theory of dynamic pricing that explains these facts as results from the same fundamental friction:...

We investigate the effect of COVID-19 epidemic and the subsequent stay-at-home order on market efficiency in China’s online markets, by comparing the changes in price dispersion around the date of the lockdown with the corresponding changes in the same period in the lunar year of 2019. We find...

We analyze price dispersion using panel data from a large price comparison site. We use past pricing behavior to instrument for potential endogeneity that might result from the selection of firms to certain product markets. We find that greater price adjustment costs result in greater price...

This paper studies the competitive role of list prices. We argue that such prices are often more salient than actual retail prices, so consumers' purchase decisions may be influenced by them. Two firms compete by setting prices in a homogeneous product market. They first set a list price that...

Many different events happened in 2014 that affected Russia’s domestic markets. Among different dairy products, cheese has been the one for which domestic production has significantly increased and cheese import decreased since the summer of 2014. This paper aims to explore the effects of...

We use a large dataset on retail pricing to document that a sizeable portion of the cross-sectional variation in the price at which the same good trades in the same period and in the same market is due to the fact that stores that are, on average, equally expensive set persistently different...

A price dispersion equation is tested with data from the German hyper-inflation. The equation is derived from a version of Lucas' (1973) and Barro's (1976) partial information-localized market models. In this extension, different excess demand elasticities across commodities imply a testable...

This paper reports an empirical test of a price dispersion equation, using data on the U.S. after World War II. The equation, derived elsewhere from aversion of the partial information-localized market models, relates price dispersion to the magnitude of changes in the aggregate disturbances. In...

Imperfect and costly information generates price dispersion in the market. This study employs data on housing assets listed for sale on a leading online classified home service in Israel to assess the effect of quality-adjusted housing price dispersion on time-on-market. We develop a model by...

Using data collected between August 1999 and January 2000 covering 399 books, including New York Times bestsellers, computer bestsellers, and random books, we examine pricing by thirty-two online bookstores. One common prediction is that the reduction in search costs on the Internet relative to...

Advertising is an input for many final goods, and broadcast television comprises a significant portion of ad-spending in the U.S. Yet advertisers face different costs when purchasing national television ads. We seek to confirm empirically whether there are differences in firms' costs to...

This papers analyzes dispersion in the prices that an airline charges to different customers on the same route. Such variation in airlines fares is substantial: the expected absolute difference in fares between two of an airline's passengers on a route averages thirty-six percent of the...

We study how consumer search affects pricing in markets with incumbents and entrants using panel data on German electricity retail markets. Consumers observe the baseline price of the incumbent and decide whether or not to search. Incumbent providers can price discriminate between searching and...

In product markets, there exists substantial dispersion in prices for transactions of physically identical goods, and incumbent sellers sell at higher prices than entrants. This study develops a theory of dynamic pricing that explains these facts as results from the same fundamental friction:...

Agricultural commodity markets in developing countries are characterized by high transaction costs and risks that reduce trade flows among spatial markets. In this article, we examine whether institutionalized agricultural commodity exchange markets reduce transaction costs and hence spatial...

Artículo de revista ; This article describes the boom of recent years in e-commerce in Spain, which reached a 14% share of sales in 2016, similar to the euro area average. The COVID-19 pandemic may have accelerated this trend, with some authors indicating a 6 pp increase in the share of sales...

REVISED: 8/1/18: We use a large data set on retail pricing to document that a sizable portion of the cross-sectional variation in the price at which the same good trades in the same period and in the same market is due to the fact that stores that are, on average, equally expensive set...

This article uses networks to study price dispersion in seller-buyer markets where buyers with unit demand interact with multiple, but not all, sellers; and buyers and sellers compete on prices after they meet. The central finding of this article is that price dispersion is determined by the...

Collecting information on prices is a costly endeavor. The cost depends on the relative ease with which those prices can be collected, and in many retail gasoline markets, there is a substantial divide in the ease of collecting information with regular grade gasoline on one side of the divide...

Agricultural commodity markets in developing countries are characterized by high transaction costs and risks that reduce trade flows among spatial markets. We examine whether institutionalized agricultural commodity exchange markets reduce transaction costs and hence spatial price dispersion...

We document wide dispersion in the mortgage rates that households pay on identical loans, and show that borrowers' financial sophistication is an important determinant of the rates obtained. We estimate a gap between the 10th and 90th percentile mortgage rate that borrowers with the same...
