It is believed that market power of the input supplier, charging a linear price, is detrimental for the consumers since it creates the double marginalisation problem. We show that this view may not be true if the final goods producers can adopt strategies to reduce rent extraction by the input...

We evaluate the welfare effects of the Roam-Like-At-Home regulation, which drastically re-duced the price of accessing the mobile internet for EU residents when traveling abroad in the European Economic Area. Estimates from individual-level usage data suggest that consumer surplus increased by...

We analyze competition between data intermediaries collecting information on consumers, which they sell to firms for price discrimination purposes. We show that competition between data intermediaries benefits consumers by increasing competition between firms, and by reducing the amount of...

We study how experts influence consumer behavior and welfare by focusing on the Booker Prize. Leveraging the discontinuity created by the attribution of the prize, we show that readers receive the signal sent by the jury of the Booker and are persuaded to buy the awarded book but experience...

The most important economic measures are monetary. They have many different names, are derived in different theories and employ different formulas. Yet, they all attempt to do basically the same thing: to separate a change in nominal value into a "real part" due to the changes in quantities and...

This paper explores the effects of a European airline merger followed by a consolidation of two competing international alliances. The exercise has been inspired by the Air France-KLM merger, which is expected to spur consolidation of the Northwest-KLM and SkyTeam alliances into a single...

We embed a North-South trade model into an incomplete contracts setting where the production of heterogeneous firms can be geographically separated. When a Northern headquarter contracts with a Southern supplier instead of a Northern supplier, the presence of international incomplete contracts...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

We analyze the incidence and welfare effects of unit sales taxes in experimental monopoly and Bertrand markets. We find, in line with economic theory, that firms with no market power are able to shift a high share of a tax burden on to consumers, independent of whether buyers are automated or...
