Access to Digital Finance: Equity Crowdfunding across Countries and Platforms

Financing entrepreneurship spurs innovation and economic growth. Digital financial platforms that crowdfund equity for entrepreneurs have emerged globally, yet they remain poorly understood. We model equity crowdfunding in terms of the relationship between the number of investors and the amount of money raised per pitch. We examine heterogeneity in the average amount raised per pitch that is associated ...

The Long-Term Effects of Measles Vaccination on Earnings and Employment: A Replication Study of Atwood (American Economic Journal: Economic Policy, 2022)

Atwood analyzes the effects of the 1963 U.S. measles vaccination on long-run labor market out-comes, using a generalized difference-in-differences approach. We reproduce the results of this paper and perform a battery of robustness checks. Overall, we confirm that the measles vaccination had positive labor market effects. While the negative effect on the likelihood of living in povertyand the positive ...

Examining Double Standards in Layoff Preferences and Expectations for Gender, Age, and Ethnicity When Violating the Social Norm of Vaccination

Whether vaccination refusal is perceived as a social norm violation that affects layoff decisions has not been tested. Also unknown is whether ascribed low-status groups are subject to double standards when they violate norms, experiencing stronger sanctions in layoff preferences and expectations, and whether work performance attenuates such sanctioning. Therefore, we study layoff preferences and expectations ...

Where Do They Care? The ECB in the Media and Inflation Expectations

This paper examines how news coverage of the European Central Bank (ECB) affects consumer inflation expectations in the four largest euro area countries. Utilizing a unique dataset of multilingual European news articles, we measure the impact of ECB-related inflation news on inflation expectations. Our results indicate that German and Italian consumers are more attentive to this news, whereas in Spain ...

Power Sector Effects of Green Hydrogen Production in Germany

The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...

House Price Expectations

This study examines short-, medium-, and long-run price expectations in housing markets. At the heart of our analysis is the combination of data from a tailored in-person household survey, past sale offerings, satellite imagery on developable land, and an information treatment (RCT). As novel finding, we show that price expectations show no evidence for momentum-effects in the long run. We also do ...

Health of Parents, Their Children's Labor Supply, and the Role of Migrant Care Workers

We estimate the impact of parental health on adult children’s labor market out- comes. We focus on health shocks that increase care dependency abruptly. Our estimation strategy exploits the variation in the timing of shocks across treated families. Empirical results based on administrative data show a significant negative impact on the labor market activities of children. This effect is more pronounced for ...

Social Dynamics and Affect: Investigating Within-Person Associations in Daily Life Using Experience Sampling and Mobile Sensing

Social interactions are crucial to affective well-being. Still, people vary interindividually and intraindividually in their social needs. Social need regulation theories state that mismatches between momentary social desire and actual social contact result in lowered affect, yet empirical knowledge about this dynamic regulation is limited. In a gender- and age-heterogenous sample, German-speaking ...

Green or Greedy: The Relationship between Perceived Benefits and Homeowners’ Intention to Adopt Residential Low-carbon Technologies

Transitioning to a net-zero economy requires a nuanced understanding of homeowners’ decision-making pathways when considering the adoption of Low Carbon Technologies (LCTs). These LCTs present both personal and collective benefits, with positive perceptions critically influencing attitudes and intentions. Our study analyses the relationship between two primary benefits: the household-level financial ...

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 ...

Unilateral Tax Policy in the Open Economy

This paper examines the effects of a unilateral reform of a redistributive tax-transfer system in an open economy. Compared to autarky, a tax increase leads to a smaller decline in aggregate income in the open economy, and it is also more effective at reducing income inequality, provided the tax rates are sufficiently low. Aggregating effects on income and income inequality using an Atkinson social ...

Immigration, Female Labour Supply and Local Cultural Norms

We study the local evolution of female labour supply and cultural norms in West Germany in reaction to the sudden presence of East Germans who migrated to the West after reunification. These migrants grew up with high rates of maternal employment, whereas West German families mostly followed the traditional breadwinner-housewife model. We find that West German women increase their labour supply and ...

Policy Complementarity and the Paradox of Carbon Pricing

We present an economics framework appropriate to the exceptionally broad scope of the climate change problem. This considers that economic and social processes, particularly those involved in purposive transitions of energy technologies and systems, involve the interplay between three distinct domains of decision-making and associated actors. The first concerns small-scale and often short-term decision-making, ...

Entrepreneurship, Management, and Cognitive Reflection: A Preregistered Replication Study With Extensions

Intuition is a central element of entrepreneurial decision-making. We conceptually replicate a published study by using new representative data from 1961 adults and the widely used Cognitive Reflection Test, which assesses the ability to avoid intuitive decisions and to switch to an analytical process. We extend the analysis by exploring occupational sorting versus environmental influence as mechanisms, ...

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 ...

Brothers in Arms: The Value of Coalitions in Sanctions Regimes

This paper examines the impact of coalitions on the economic costs of the 2012 Iran and 2014 Russia sanctions. By estimating and simulating a quantitative general equilibrium trade model under different coalition setups, we (1) dissect welfare losses for sanctions senders and target; (2) compare prospective coalition partners; (3) investigate ‘optimal’ coalitions that maximize payoff from sanctions; ...

Adding Household Surveys to the Behavioral Economics Toolbox: Insights from the SOEP Innovation Sample

While laboratory and field experiments are the major items in the toolbox of behavioral economists, household panel studies can complement them and expand their research potential. We introduce the German Socio-Economic Panel’s Innovation Sample (SOEP-IS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We discuss what ...

Disentangling COVID-19, Economic Mobility, and Containment Policy Shocks

We study the dynamic interaction between COVID-19, economic mobility, and containment policy. We use Bayesian panel structural vector autoregressions with daily data for 44 countries, identified through traditional and narrative sign restrictions. We find that incidence shocks and containment shocks have large and persistent effects on mobility, morbidity, and mortality that last for one to two months. ...
