Targeting Viewers’ Heterogeneous Ad Aversion: Evidence from a Two-Sided Market

This paper studies the role of viewers’ heterogeneous ad aversion on media content demand and advertisers’ willingness to pay. High-frequency individual-level data on broadcast media content allows us to track viewers’ minute-by-minute choices within the set of available alternatives. We first illustrate the potential selection biases that arise when using aggregated market-level data to estimate...

Quantifying the Fiscal Channel of Monetary Policy

In macroeconomic models featuring borrowing-constrained agents, the effects of monetary policy depend on the fiscal reaction to interest rate changes. This paper presents new evidence on the dynamic causal effects of U.S. monetary policy shocks on fiscal instruments and estimates a Heterogeneous Agent New Keynesian model with fiscal feedback rules to match the empirical results. I find that U.S. fiscal ...

Agents, Landlords and Tenants: Price Regulation in a Thick Two-sided Market

This paper examines the impacts of new policies aimed at reducing the cost of renting by regulating the actions of intermediaries in the rental market. We highlight how information frictions between buyers and intermediaries can give rise to rents in the thick two-sided market. The distribution of these rents between intermediaries and sellers, as well as the impact of price regulation, depends on...

Steering of Consumer Behavior by Conversational Artificial Intelligence

Conversational AI models are becoming increasingly popular and are about to replace traditional search engines for information retrieval and product discovery. This raises concerns about monetization strategies and the potential for subtle consumer manipulation. Companies may have financial incentives to steer users toward search results or products in a conversation in ways that are unnoticeable...

Large mergers between manufacturers typically impact competition, thus requiring the approval of Competition Authorities. Divestitures are often a condition of merger approval. This report investigates the effectiveness of implementing ...

Earn More Tomorrow: Overconfidence, Income Expectations, and Consumer Indebtedness

This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

Using granular data between 2018 and 2023, we estimate an Auto ...
