Platforms often use fee discrimination within their marketplace (e.g., Amazon, eBay, and Uber specify a variety of merchant fees). To better understand the impact of marketplace fee discrimination, we develop a model that allows us to determine equilibrium fee and category decisions that depend...

We investigate the relationship between market structure and platforms' incentives to adopt technological innovations in two-sided markets, where platforms may find it optimal to charge zero price on the consumer side and to extract surplus on the advertising side. We consider innovations that...

The TV industry is a two-sided market where both advertisers and viewers buy access to the programs offered by competing TV channels. Under the current market structure advertising prices are typically set by TV channels while viewer prices are set by distributors (e.g. cable operators). The...

When the public provision of private goods is partial rather than universal, public supply may be supplemented by the entry of private firms in the market for the private good. The main purpose of this paper is to explore whether partial public provision helps or hinders aggregate access to the...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level...

Using a difference-in-differences identification strategy on a micro panel at the bank and firm level, we study the transmission effectiveness of ECB’s large-scale asset purchasing programs programs (i.e. APP and PEPP) in the Euro area. Our findings show: first, balance sheet composition of...

We explore how changes in capital-based macroprudential regulation in the euro area affect the exposure of national banking sectors to domestic government debt, thus strengthening or weakening the sovereign-bank nexus. To do so, we construct a measure of macroprudential policy based on the...

We estimate a logit mixture vector autoregressive model describing monetary policy transmission in the euro area over the period 2003Q1–2019Q4 with a special emphasis on credit conditions. With the help of this model, monetary policy transmission can be described as mixture of two states...

We estimate a panel VAR model for the euro area to quantitatively asses the contribution of the TARGET2 system to the propagation of different types of structural economic shocks as well as to the historical evolution of aggregate economic activity in euro area member countries. Our results...
