The object of this paper is to discuss on-line intermediation from the perspective of two-sided markets. It builds a simple model of the intermediation activity when trading partners are involved in a commercial relationship and uses it to illustrate some of the results that emerge in the...

This paper investigates price-setting for truly homogenous products sold in markets without any formal trade barriers. We use data from IKEA, a furniture company selling identical products in an identical shopping environment in different EU countries. We get four remarkable outcomes: 1) The law...

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price (LOOP). For identical products, we find typical deviations of twenty to fifty percent, though there is muted evidence for convergence over time. Such...

Endogenous timing can help to derive the time structure of decision making instead of assuming it as exogenously given. In our study we consider a homogeneous market where, like in the model of Kreps and Scheinkman (1983), sellers determine sales capacities before prices. Sellers must serve...

We characterize the evolution of markups for consumer products in the United States from 2006 to 2019. We use detailed data on prices and quantities for products in more than 100 distinct product categories to estimate demand systems with flexible consumer preferences. We recover markups under...

Standard production-based markup estimators are biased and inconsistent when output prices are unobserved. Absent additional assumptions, researchers cannot disentangle whether firms have higher revenues because of higher productivity or higher markups. We propose a method that generates...

E-commerce has become more prevalent throughout Europe in the last decade. The coronavirus (COVID-19) pandemic accelerated this trend, particularly in the retail sector. This paper focuses on the implications of increasing business-to-consumer ecommerce for prices and inflation in the euro area....

The coronavirus (COVID-19) pandemic caused a deep recession globally, as well as in the euro area, accompanied by a steep decline in inflation rates in 2020. This paper reviews some of the main challenges created by the pandemic for inflation measurement and provides micro price data analysis of...

Pricing technology that allows firms to rapidly adjust prices has two potential benefits. Prices can respond more rapidly to demand shocks, leading to higher revenues. On the other hand, time-varying prices can be used to smooth out demand across periods, reducing costs in markets with capacity...
