    Have the Effects of Shocks to Oil Price Expectations Changed? Evidence from Heteroskedastic Proxy Vector Autoregressions

    Studies of the crude oil market based on structural vector autoregressive (VAR) models typically assume a time-invariant model and transmission of shocks and possibly allow for heteroskedasticity by using robust inference procedures. We assume a heteroskedastic reduced-form VAR model with time-invariant slope coefficients and explicitly consider the possibility of time-varying shock transmission due ...

    Hicks in HANK: Fiscal Responses to an Energy Shock

    The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model that we calibrate to the euro area. Energy subsidies can stabilize the domestic economy, but are fiscally costly and generate adverse spillovers to the rest of the monetary union: What the subsidizing country gains, the other ...

    Government Ownership and Competition: Evidence from the European Airline Industry following the COVID-19-Pandemic

    This paper empirically analyses the impact of government ownership on competition. The COVID-19 pandemic and subsequent governmental equity interventions in the European airline industry provides for a particularly ideal setting to investigate this topic, and this for several reasons. First, airline markets and competition therein are well-defined and well-understood. Second, European countries...

    How Shocks Affect Stock Market Participation

    While there is a broad consensus in the literature that stock ownership is associated with individual characteristics, such as wealth, income, risk preferences, and financial literacy, less is known about the dynamics of stock market participation (SMP). Major fluctuations in SMP are oftentimes related to political events, economic shocks, and technological disruptions. We discuss the literature...

    Sponsored Bids in Online Labor Markets

    Advertising on e-commerce platforms, which enables third-party sellers to place their products as sponsored listings within organic results, is a widespread phenomenon, creating large revenues for online marketplaces. While economic theory suggests that advertising can serve as a signal for product quality, the empirical evidence is ambiguous. In this project, I collect data from a leading online...

    The Emission Intensity Effect: Carbon Border Adjustments in the Presence of Heterogeneous Firms

    In the absence of globally coordinated action to combat climate change, governments are concerned that ambitious carbon pricing could harm the competitiveness of emission-intensive industries. A prominent measure to prevent that manufacturing producers relocate to countries with laxer environmental regulation are carbon border adjustments often referred to as carbon tariffs. Several studies have...

    Economic sanctions: Coalitions increase the cost for the target and reduce own burden

    What is the role of coalitions in enforcing sanctions? In a newly released study, researchers at IfW Kiel and DIW Berlin analyse the economic impact of jointly implementing punitive measures in the context of the 2012 Iran and 2014 Russia sanctions. They find that coalitions serve two crucial purposes -- they not only magnify the economic cost imposed on the target but also reduce domestic costs for ...

    Competition and Mergers with Strategic Data Intermediaries

    We analyze mergers between strategic data intermediaries collecting consumer information that they sell to firms competing in a product market. We show that a merger: (a) reduces the intensity of competition in the product market through a change in the selling strategies of merging intermediaries; (b) increases data collection, reducing consumer surplus through a better rent extraction. We argue...
