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 ...

Sin Taxes and Self-Control

According to theory, "sin taxes" are welfare improving if consumers with low self-control respond at least as much to the tax as consumers with high self-control. We investigate empirically if demand response to soft drink and fat tax variations in Denmark depends on consumers' self-control. We use a unique home-scan panel that includes a survey measure of self-control. When taxes increase, consumers ...

Codevelopment of Life Goals and the Big Five Personality Traits across Adulthood and Old Age

Since the new millennium, research in the field of personality development has focused on the stability and change of basic personality traits. Motivational aspects of personality and their longitudinal association with basic traits have received comparably little attention. In this preregistered study, we applied bivariate latent growth curve model to investigated the codevelopment of nine life goals ...

SOEP-LEE2: Linking Surveys on Employees to Employers in Germany

This article presents the new linked employee-employer study of the Socio-Economic Panel (SOEP-LEE2), which offers new research opportunities for various academic fields. In particular, the study contains two waves of an employer survey for persons in dependent work that is also linkable to the SOEP, a large representative German annual household panel (SOEP-LEE2-Core). Moreover, SOEP-LEE2 includes ...

The Impact of Public Procurement on Financial Barriers to General and Green Innovation

This study investigates whether public procurement mitigates or exacerbates innovative enterprises’ financial constraints. We distinguish between general and environmentally beneficial innovative enterprises. Theory suggests that the treatment effects of public procurement, particularly when mediated by the demand-pull effect, may lower a company’s funding constraints for innovation. We test this theory ...

Working Life and Human Capital Investment: Causal Evidence from a Pension Reform

Should Mama or Papa Work? Variations in Attitudes towards Parental Employment by Country of Origin and Child Age

Employment among mothers has been rising in recent decades, although mothers of young children often work fewer hours than other women do. Parallel to this trend, approval of maternal employment has increased, albeit not evenly across groups. However, differences in attitudes remain unexplored despite their importance for better understanding mothers’ labour market behaviour. Meanwhile, the employment ...

Transactional Effects between Personality and Religiosity

Do changes in religiosity beget changes in personality, or do changes in personality precede changes in religiosity? Existing evidence supports longitudinal associations between personality and religiosity at the between-person level, such that individual differences in personality predict subsequent individual differences in change in religiosity. However, no research to date has examined whether ...

How Flexible Electrification Can Integrate Fluctuating Renewables

To phase out fossil fuels, energy systems must shift to renewable electricity as the main source of primary energy. In this paper, we analyze how electrification can support the integration of fluctuating renewables, like wind and PV, and mitigate the need for storage and thermal backup plants. Using a cost-minimizing model for system planning, we find substantial benefits of electricity demand in ...

Digitisation and Renaissance of the Manufacturing Industry in Major Cities: The Case of Berlin

The rise of digitisation will cause a major upheaval in the manufacturing industries, bringing changes to traditional industrial location patterns as well. In order to understand the direction these structural changes are taking, this paper analyses the start-up activity in the industrial sector. The frontrunners are metropolitan regions and in particular major cities such as Berlin or Munich. Furthermore, ...

Estimating the Marginal Costs of Road Renewals: Evidence from a Duration Approach

Within an analytical approach that mirrors the relationship between road deterioration, traffic load, and road renewal, we estimate the marginal costs of road renewals as part of a social marginal cost scheme for road charging. Based on a comprehensive data set for German motor ways, we estimate a Weibull dura tion model with shared frailties that account for unobserved heterogeneity, including covariates ...

Assortative Mating and Wealth Inequalities between and within Households

Positive assortative mating may be a driver of wealth inequalities, but this relationship has not yet been examined. We investigate the association between assortative mating and wealth inequality within and between households drawing on data from the United States Survey of Income and Program Participation and measuring current, individual-level wealth for newly formed couples (N = 3936 couples). ...

Atypical Work, Financial Assets, and Asset Poverty in Germany

This study investigates how atypical employment (i.e., part-time, temporary work, mini-jobs) affects workers' ability to accumulate financial assets and exposes them to asset poverty in Germany. Asset poverty occurs when household financial resources (e.g., bank deposits and stock equity) are insufficient to live at the income poverty line for three months. Previously, studies on labour market processes ...

Infection Rates Matter – Especially for People from Lower Social Class: A Large-Scale Investigation of the Impact of the COVID-19 Pandemic on Mental Health

The COVID-19 pandemic was a long-lasting and stressful event that had enormous psychological, economic, and social consequences. This study extends prior research by examining the relationship between infection rates and mental health as well as its dependency on social class. Therefore, we used large-scale data from a nationwide sample (N = 5,742) across two time periods in the COVID-19 pandemic in ...

Reacting to Changing Paradigms: How and Why to Reform Electricity Markets

The energy crisis and the accelerated transition to climate neutrality result in a shift from the traditional energy trilemma to an “energy quartet” across Europe. Firstly, the criteria of affordability, previously focused on short-term price developments, broadens to reliable affordability including in crises. Secondly, clean energy traditionally focused on clean production now extends to clean energy ...

Wealth in Couples: Introduction to the Special Issue

The assumption that economic resources are equally shared within households has been found to be untenable for income but is still often upheld for wealth. In this introduction to the special issue “Wealth in Couples”, we argue that within-household inequality in wealth is a pertinent and under-researched area that is ripe for development. To this end, we outline the relevance of wealth for demographic ...

The Signalling Channel of Negative Interest Rates

Negative policy rates can convince markets that deposit rates will remain lower-for-longer, even when current deposit rates are constrained by zero. This is the signalling channel of negative interest rates. We analyse the optimality and effectiveness of negative rates in the context of this novel transmission channel. In a stylized model, we prove two necessary conditions for optimality: time-consistency ...

Energy Transition Metals: Bottleneck for Net-Zero Emissions?

The energy transition requires substantial amounts of metals, including copper, nickel, cobalt, and lithium. Are these metals a bottleneck? We identify metal-specific demand shocks, estimate supply elasticities, and study the price impact of the transition in a structural scenario analysis. Prices of these four metals would reach previous historical peaks but for an unprecedented, sustained period ...

Assessing the Effects of District-Level Segregation on Meritocratic Beliefs in Germany

In recent years, researchers have grappled with the phenomenon that public demand for redistribution has not systematically increased in response to rising inequality. Meritocratic beliefs have been suggested as an explanation for this observation, because they can help legitimize inequalities. Past research has identified local-level inequality, segregation, or diversity as important factors for how ...
