We study changes in markups across 72 product markets from 2006 to 2018. A growing literature has documented a rise in markups over time using a production function approach; we instead employ the standard microeconomic method, which is to estimate demand and then invert firms' first-order...

In principle, a multiproduct firm can set separate prices for all possible bundled combinations of its products (i.e., "mixed bundling"). However, this is impractical for firms with more than a few products, because the number of prices increases exponentially with the number of products. In...

We study the impact of mandatory calorie posting on consumers’ purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers’ food choices—there is almost no change in...

We examine pricing strategies for a multiproduct monopolist. We show that simple quantity discounting strategies are almost as profitable as fully optimal bundling. We investigate this in an empirical example, using data from a theater company

We estimate an equilibrium model of ticket resale in which consumers' and brokers' decisions in the primary market reflect rational expectations about the resale market. Estimation is based on a unique dataset that merges transaction details from both the primary and secondary markets for...

We develop a model of herds in which consumers observe only the aggregate purchase history, not the complete ordered history of search actions. We show that the purchasing information changes the conditions under which herds can occur for both low- and high-quality products. Inferior products...

Technologies that enable free redistribution of digital goods (e.g., music, movies, software, books) can undermine sellers’ ability to profitably sell such goods, which raises concerns about the future development of socially valuable digital products. In this paper we explore the possibility...

Changes in technologies for reproducing and redistributing digital goods (e.g., music, movies, software, books) have dramatically affected profitability of these goods, and raised concerns for future development of socially valuable digital products. However, broader illegitimate distribution of...
