I study the labor market risks associated with being self-employed. I document that the self-employed are subject to larger earnings fluctuations than employees and that they frequently transition into unemployment. Given the self-employed are not eligible to unemployment insurance, I analyze...

The increasing impact of natural disasters (floods, earthquakes, landslides, and avalanches) in Afghanistan, notably flooding and similar climate shocks, poses a growing concern as vulnerability to climate change intensifies the potential severity of these impacts in future. This paper uses two...

We estimate the unconditional distribution of the marginal propensity to consume (MPC) using clustering regression applied to the 2008 economic stimulus payments. By deviating from the standard approach of estimating MPC heterogeneity using interactions with observables, we can recover the full...

Does online fundraising increase charitable giving? Using the Facebook advertising tool, we implemented a natural field experiment across Germany, randomly assigning almost 8,000 postal codes to Save the Children fundraising videos or to a pure control. We studied changes in the donation revenue...

This paper analyzes a merger of large manufacturers with divestiture in the French coffee market. In contrast to previous approaches used to study the effects of upstream divestitures on prices and welfare, we model the vertical market structure. First, our results show that the standard policy...

Im Rahmen der Wettbewerbspolitik spielt neben dem Kartellverbot und der Missbrauchsaufsicht die Fusionskontrolle eine zentrale Rolle. Fusionen zwischen großen Herstellern beeinflussen typischerweise den Wettbewerb und müssen daher von den Wettbewerbsbehörden genehmigt werden. Dabei sind...

Steuern auf ungesunde Lebensmittel, zum Beispiel zuckergesüßte Getränke, sollen Verbraucher*innen einen Anreiz geben, sich gesünder zu ernähren. Im Fokus dieser Politik stehen besonders Menschen mit niedriger Selbstkontrolle, die ihren Zuckerkonsum weniger unter Kontrolle haben. Dieser...

We use micro-level data on fuel consumption, mileage, and travel mode to study plug-in hybrid drivers’ response to fuel prices. When fuel prices rise, plug-in hybrids reduce fuel consumption more than gasoline and diesel cars. They do not reduce their mileage but increase electric recharging,...

Interventions to decrease meat consumption are often only implemented for short periods of time, and it is unclear how they might have lasting effects. We combine student canteen consumption (over 270, 000 purchases made by over 4, 500 guests) and survey data (N 800) to study how a one-month...
