To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

From an analysis of the time series of volatility using recent high frequency data, Gatheral, Jaisson and Rosenbaum previously showed that log-volatility behaves essentially as a fractional Brownian motion with Hurst exponent H of order 0.1, at any reasonable time scale. The resulting Rough...

In this paper, we study the price partitioning decisions of online retailers regarding shipping and handling (S&H) fees. Specifically, we analyze two partitioning formats used by retailers in this context. In the first scenario, retailers present customers with a price that is partitioned into a...

Price inflation in the euro area has been stable and low since the Global Financial Crisis, despite notable changes in output and unemployment. We show that an increasing share of high markup firms is part of the explanation of why inflation remained stubbornly stable and low in the euro area...

Online data was collected for 350,000 products from over 65 fashion retailers in the U.S. and the U.K. Many retailers practice an extreme form of stickiness described as quantum prices: a large number of differentiated products are priced using few sparse prices, with price changes occurring...

The profiteering developer is a common figure in debates over housing policy. Governments increasingly use developer profits to justify policies like inclusionary housing. Yet, we actually understand little about the competitiveness of housing development. One unresolved question is whether...

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...

Can an increasing importance of intangible capital explain increases in markups and profits? I use a heterogeneous firm model to show how intangible capital, characterized by fixed costs and uncertainty, is related to markups and profits at the industry level. The scalability and uncertainty...
