Rent Control, Market Segmentation, and Misallocation: Causal Evidence from a Large-Scale Policy Intervention

This paper studies market segmentation that arises from the introduction of rent control. When a part of the market remains unregulated, theory predicts an increase of free-market rents due to the misallocation of households to dwellings. To document this mechanism empirically, we study a large-scale policy intervention in the German housing market. We isolate the misallocation mechanism by exploiting ...

The Expansion of Natural Gas Infrastructure Puts Energy Transitions at Risk

Whether additional natural gas infrastructure is needed or would be detrimental to achieving climate protection goals is currently highly controversial. Here we combine five perspectives to argue why expansion of the natural gas infrastructure hinders a renewable energy future and is no bridge technology. We highlight that natural gas is a fossil fuel with a significantly underestimated climate impact ...

Do Words Hurt More than Actions? The Impact of Trade Tensions on Financial Markets

We use machine learning techniques to quantify trade tensions between the United States and China. Our measure matches well-known events in the US-China trade dispute and is exogenous to the developments on global financial markets. Local projections show that rising trade tensions leave US markets largely unaffected, except for firms that are more exposed to China, while negatively impacting stock ...

How Migration Status Shapes Susceptibility of Individuals’ Loneliness to Social Isolation

Objectives: Our research provides competing hypotheses and empirical evidence how associations between objectively social isolation and subjective loneliness differ between host populations, migrants, and refugees.Methods: The analysis uses data of 25,171 participants from a random sample of the German population (SOEP v.35). We estimate regression models for the host population, migrants, and refugees ...

Substituting Clean for Dirty Energy: A Bottom-Up Analysis

We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of substitution between clean and dirty energy. Central results show that (i) dirty inputs are not essential for production. ...

Institutional Coordination Arrangements as Elements of Policy Design Spaces: Insights from Climate Policy

This study offers insights into the institutional arrangements established to coordinate policies aiming at the mitigation of and adaptation to climate change. Drawing on the literature on policy design, we highlight institutional arrangements as elements of policy design spaces and contend that they fall into four categories that either stress the political or problem orientation of this activity: ...

The Rise and Fall of Social Housing? Housing Decommodification in Long-run Comparison

The comparative study of housing decommodification lags behind classical welfare state research, while housing research itself is rich in homeownership studies but lacks comparative accounts of private and social rentals due to missing comparative data. Building on existing works and various primary sources, this study presents a new collection of up to forty-eight countries’ social housing shares ...

Parental Leave Policy and Long-run Earnings of Mothers

Paid parental leave schemes have been shown to increase women’s employment rates but to decrease their wages in case of extended leave duration. In view of these potential trade-offs, many countries are discussing the optimal design of parental leave policies. We analyze the impact of a major parental leave reform on mothers’ long-term earnings. The 2007 German parental leave reform replaced a means-tested ...

Grenzen und Fortschritte indikatorengestützter Politik am Beispiel der Corona-Pandemie: Heinz-Grohmann-Vorlesung 2020/21

Indikatoren sollen der Steuerung von (sozialen) Prozessen dienen. Sie beschreiben jedoch die Realität in der Regel nur deskriptiv und unvermeidlich mit mehr oder weniger großen und systematischen Messfehlern behaftet. Insofern ist es im Allgemeinen alles andere als einfach mit Hilfe von Indikatoren zu steuern; insbesondere dann, wenn für Problembereiche (fehlerbehaftete) Zielwerte vorgegeben werden, ...

An Alternative Bootstrap for Proxy Vector Autoregressions

We propose a new bootstrap algorithm for inference for impulse responses in structural vector autoregressive models identified with an external proxy variable. Simulations show that the new bootstrap algorithm provides confidence intervals for impulse responses which often have more precise coverage than and similar length to the competing moving-block bootstrap intervals. An empirical example shows ...

Nationally Representative Results on SARS-CoV-2 Seroprevalence and Testing in Germany at the End of 2020

Pre-vaccine SARS-CoV-2 seroprevalence data from Germany are scarce outside hotspots, and socioeconomic disparities remained largely unexplored. The nationwide representative RKI-SOEP study (15,122 participants, 18–99 years, 54% women) investigated seroprevalence and testing in a supplementary wave of the Socio-Economic-Panel conducted predominantly in October–November 2020. Self-collected oral-nasal ...

Factors Affecting Rental Prices in the Russian Empire

In this study, we investigate the determinants of rental prices in Russian Empire prior to World War I and the variation of housing rents across cities. For our research, we use statistical data on 1232 cities in 1910. Our analysis shows that the urban rents in imperial Russia were affected by such city characteristics as its population structure, prices for different goods, and the geographical position. ...

The Hidden Homeownership Welfare State: An International Long-term Perspective on the Tax Treatment of Homeowners

Welfare is traditionally understood as social security decommodifying labour markets or as social investment policies. In the domain of housing, however, welfare for homeowners is largely hidden in the tax codes’ fiscal exemptions. Based on a content analysis of legislation, this article introduces a novel yearly database of 37 countries between 1901 and 2020 to uncover the “hidden welfare state” of ...

Foreign Exchange Intervention: A New Database

We construct a novel database of monthly foreign exchange interventions for 49 countries over up to 22 years. We build on a text classification approach that extracts information about interventions from news articles and calibrate our procedure to data about actual interventions. This new dataset allows us to document stylized facts about the use of foreign exchange interventions for countries that ...

Observing Many Researchers Using the Same Data and Hypothesis Reveals a Hidden Universe of Uncertainty

This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions ...

Culture, Children and Couple Gender Inequality

This paper examines how culture impacts within-couple gender inequality. Exploiting thesetting of Germany’s division and reunification, I compare child penalties of East Germans whowere socialised in a more gender egalitarian culture to West Germans socialised in a gendertraditionalculture. Using a household panel, I show that the long-run child penalty on thefemale income share is 23.9 percentage ...

Today’s Older Adults Are Cognitively Fitter Than Older Adults Were 20 Years Ago, but When and How They Decline Is No Different Than in the Past

History-graded increases in older adults’ levels of cognitive performance are well documented, but little is known about historical shifts in within-person change: cognitive decline and onset of decline. We combined harmonized perceptual motor speed data from independent samples recruited in 1990 and 2010 to obtain 2,008 age-matched longitudinal observations (M = 78 years, 50% women) from 228 participants ...
