Let's Switch to the Cloud: Cloud Usage and Its Effect on Labor Productivity

The advent of cloud computing promises to improve the way firms use IT solutions. Firms are expected to replace large and inflexible fixed-cost investments in IT with more targeted, variable spending on cloud solutions. This is also expected to increase firms' productivity by allowing them to quickly adapt their IT infrastructure to their specific needs. We assess this claim using firm-level data provided ...

Mode Choice Inertia and Shock: Three Months of Almost Fare-Free Public Transport in Germany

This study analyses travellers’ behavioural responses to two temporal measures implemented by the German government: the reduction in public transport prices, making it almost fare-free, and a decrease in fuel taxes to the minimum level permitted by European law. Based on a panel dataset of GPS-tracked trips collected before and during the price intervention from a representative sample of 276 individuals, ...

Out for Good: Transitory and Persistent Labor Market Effects of Heterogeneous Health Shocks

We propose a novel method to detect and disentangle moderate and severe health shocks in a general population survey based on a data-driven classification of sickness absences and hospitalizations. Both types of shocks are widespread with an annual incidence of about 1.7%, which rises steeply with age. We estimate the effects of both shocks on labor market outcomes and find that severe shocks have ...

Health System Resilience in the Context of Forced Migration: A Qualitative Framework Analysis of Germany’s Crisis Responses in 2015 and 2020

BackgroundHealth system resilience, the ability of a health system to maintain its functions under stress, has received increasing attention in recent years. Shortcomings in health system resilience are often most visible in the most vulnerable settings, including the care for asylum seekers and refugees. We therefore examined how the German health system responded to challenges and uncertainties during ...

Impact of Social Isolation on Mental Health Changes by Socio-Economic Status: A Moderated Mediation Analysis among Non-migrant, Migrant, and Refugee Subpopulations in Germany, 2016–2020

Background: Populations experiencing precarity face heightened mental health inequities, especially during crises. In this regard, it is established that socio-economic status (SES) and social isolation are critical factors influencing mental health outcomes, which interact syndemically. Understanding their interrelated mechanisms is crucial for developing effective public health strategies to support ...

The Long-Term Implications of Destruction During the Second World War on Private Wealth in Germany

By the end of the Second World War, an estimated 20% of the West German housing stock had been destroyed. Building on a theoretical life-cycle model, this paper examines the persistent consequences of the war for individual wealth across generations. As our empirical basis, we link a unique historical dataset on the levels of wartime destruction in 1739 West German cities with micro data on individual ...

Wealth Creators or Inheritors? Unpacking the Gender Wealth Gap from Bottom To Top and Young to Old

There is growing interest in understanding how gender influences the accumulation of wealth. While prior studies focused on labor-related determinants, our research focuses on inheritances and gifts. Using unique survey data that oversamples the top 1% of wealth holders in Germany, we show that the gender wealth gap is small for individuals up to age 40, then widens, and declines for those past retirement ...

Euro Area Inflation Differentials: The Role of Fiscal Policies Revisited

The Non-linear Impact of Risk Tolerance on Entrepreneurial Profit and Business Survival

Entrepreneurs tend to be risk tolerant but is higher risk tolerance always better? In a sample of about 2100 small businesses, we find an inverted U-shaped relation between risk tolerance and profitability. This relationship holds in a simple bilateral regression, and even after controlling for a large set of individual and business characteristics. Apparently, one major transmission goes from risk ...
