    A HANK2 Model of Monetary Unions

    How does a monetary union alter the impact of business cycle shocks at the household level? We develop a Heterogeneous Agent New Keynesian model of two countries (HANK2) and show in closed form that a monetary union shifts the adjustment to a shock horizontally—across countries—within the brackets of the union-wide wealth distribution rather than vertically—that is, across the brackets of the union-wide ...

    Diversify or Not? – The Link between Global Sourcing of ICT Goods and Firm Performance

    Our paper contributes to the discussion about Europe’s digital sovereignty. We analyze the relationship between firm performance and the diversification of sourcing countries for imported ICT goods. The analysis is based on administrative data for 3888 German manufacturing firms that imported ICT goods in the years 2010 and 2014. We find that firms that diversify the sourcing of ICT goods across multiple ...

    When Credit Turns Political: Evidence from the Spanish Financial Crisis

    This paper provides causal evidence on the effect of credit crunches on political polarization. We combine data on bank-firm connections and electoral outcomes at the city-level during the 2008-2014 Spanish Financial Crisis. First, we show that firms in a relationship with weak banks experience a reduction in their loan supply and employment growth. Next, we estimate the effects of unemployment on ...

    De-Fueling Externalities: How Tax Salience and Fuel Substitution Mediate Climate and Health Benefits

    This paper provides a comprehensive evaluation of the world’s largest environmental tax reform. We compare carbon and air pollutant emissions of the German transport sector and synthetic counterfactuals following the 1999 eco-tax reform, and find average re- ductions in external damages of around 80 billion Euros. We further show that the eco-tax induced low-carbon innovation and document much stronger ...

    The Heterogeneous Effects of Social Assistance and Unemployment Insurance: Evidence from a Life-Cycle Model of Family Labor Supply and Savings

    We empirically analyze the heterogeneous welfare effects of unemployment insurance and social assistance. We estimate a structural life-cycle model of singles' and married couples' labor supply and savings decisions. The model includes heterogeneity by age, education, wealth, sex and household composition. In aggregate, social assistance dominates unemployment insurance; however, the opposite holds ...

    VAT Pass-Through and Competition: Evidence from the Greek Islands

    We examine how competition affects VAT pass-through in isolated oligopolistic markets as defined by the Greek islands. Using daily gasoline prices and a difference-in-differences methodology, we investigate how changes in VAT rates are passed through to consumers in islands with different market structure. We show that pass-through increases with competition, going from 50% in monopoly to around 80% ...

    Zur Geschichte des "arbeitnehmernahen" und "keynesianisch" geltenden Deutschen Instituts für Wirtschaftsforschung (DIW) seit den 50er Jahren

    Für das im Jahr 2025 stattfindende 100-jährige Jubiläum des DIW Berlin und dessen Geschichte ist die hier vorgelegte Dokumentation eines 1999 geführten Gesprächs zwischen den ehemaligen DIW-Abteilungsleitern Fritz Franzmeyer und Reinhard Pohl einerseits und Gert G. Wagner andererseits von Interesse, das die Frage thematisiert, warum das Deutsche Institut für Wirtschaftsforschung (DIW Berlin) in der ...

    The Impacts of Global Risk and US Monetary Policy on US Dollar Exchange Rates and Excess Currency Returns

    We examine the causal relationship between US monetary policy shocks, exchange rates and currency excess returns for a sample of eight advanced countries over the period 1980M1 to 2022M11. We find that the dynamics of the US dollar exchange rate is the main driver of currency excess returns. The exchange rate is significantly affected by US monetary policy shocks, where the persistence of this shock ...

    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 or they consider a time-varying model and shock transmission. We assume a heteroskedastic reduced-form VAR model with time-invariant slope coefficients and test for time-varying impulse responses in a model for the global crude oil market that includes ...

    Contracting Matters: Hedging Producers and Consumers with a Renewable Energy Pool

    Renewable energy installations are rapidly gaining market share due to falling technology costs and supportive policies. Meanwhile, the energy price crisis resulting from the Russian-Ukrainian war has shifted the energy policy debate toward the question of how consumers can benefit more from the low and stable generation costs of renewable electricity. Here we suggest a Renewable Pool (“RE-Pool”) under ...

    The Role of Carbon Pricing in Promoting Material Recycling: A Model of Multi-Market Interactions

    Recycling of raw material can make a significant contribution to achieving climate neutrality by 2050. Carbon pricing can encourage material recycling by making it more competitive with waste incineration and primary material production. However, accounting for the interactions among different markets in a theoretical model, this paper finds that carbon pricing on material manufacturing alone does ...

    The Energy-Price Channel of (European) Monetary Policy

    This study examines whether central banks can combat inflation that is caused by rising energy prices. By using a high-frequency event study and a Structural Vector Autoregression, we find evidence that the European Central Bank (ECB) and the Federal Reserve (Fed) are capable of doing so by affecting domestic and global energy prices. This “energy-price channel” of monetary policy plays an important ...

    Effectiveness and Heterogeneous Effects of Purchase Grants for Electric Vehicles

    We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022. We account for confounding time trends and interacting EU-level CO2 standards using neighboring countries as a control group. The program was cost-ineffective, as only 40% of BEV and 25% of PHEV registrations were ...

    Causal Misperceptions of the Part-Time Pay Gap

    This paper studies if workers infer from correlation about causal effects in the context of the part-time wage penalty. Differences in hourly pay between full-time and part-time workers are strongly driven by worker selection and systematic sorting. Ignoring these selection effects can lead to biased expectations about the consequences of working part-time on wages (’selection neglect bias’). Based ...

    Self-Efficacy and Entrepreneurial Performance of Start-Ups

    Self-efficacy reflects the self-belief that one can persistently perform difficult and novel tasks while coping with adversity. As such beliefs reflect how individuals behave, think, and act, they are key for successful entrepreneurial activities. While existing literature mainly analyzes the influence of the task-related construct of entrepreneurial self-efficacy, we take a different perspective and ...

    The Influence of Start-up Motivation on Entrepreneurial Performance

    Predicting entrepreneurial development based on individual and business-related characteristics is a key objective of entrepreneurship research. In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, expansion ...

    Age-specific Effects of Early Daycare on Children's Health

    Over the past decades, the share of very young children in daycare has increased significantly in many OECD countries, including Germany. Despite the relevance of child health for child development and later life success, the effect of early daycare attendance on health has received little attention in the economic literature. In this study, I investigate the impact of a large daycare expansion in ...

    Non-Additivity of Subjective Expectations over Different Time Intervals

    We examine the additivity of stock-market expectations over different time intervals. When asked about a ten-year interval, survey respondents expect a stock-price change that is not equal to, but closer to zero than, the sum of their expectations over two shorter time intervals that cover the same ten years. Such sub-additivity is irrational in that it cannot stem from aggregating short-term expectations. ...

    Rent Control Effects through the Lens of Empirical Research: An almost Complete Review of the Literature

    Rent control is a highly debated social policy that has been omnipresent since World War I. Since the 2010s, it is experiencing a true renaissance, for many cities and countries facing chronic housing shortages are desperately looking for solution, directing their attention to controling housing rents and other restrictive policies. Is rent control useful or does it create more damage than utility? ...

    Wind Power Decreases the Need for Storage in an Interconnected 100% Renewable European Power Sector

    The massive expansion of wind power and solar PV is the primary strategy to reduce greenhouse gas emissions in many countries. Due to their variable generation profiles, power sector flexibility needs to increase. Geographical balancing enabled by electricity grids and temporal flexibility enabled by electricity storage are important options for flexibility. As they interact with each other, we investigate ...
