EU Power Market Reform Toward Locational Pricing: Rewarding Flexible Consumers for Resolving Transmission Constraints

The ongoing expansion of wind and solar electricity generation alongside increasing electrification is leading to a considerable strain on transmission capacities and grid bottlenecks in the EU. Coping with this challenge requires increasing system flexibility, e.g. by exploiting the potential for demand-side flexibility. However, in the current market design, demand-side flexibility responds to zonal ...

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 ...

Euro Area Inflation Differentials: The Role of Fiscal Policies Revisited

Wage Risk and Portfolio Choice: The Role of Correlated Returns

From standard portfolio-choice theory, it is well-understood that background risk, primarily due to wage risk, is one of the central determinants of individuals’ portfolio composition: higher background risk reduces risky investments. However, if background risk is negatively correlated with financial market risk, higher background risk implies a more risky investment. We quantify the influence of ...

Disentangling Structural Change, Servitization, and Skill-Biased Change

This paper analyzes three key labor market trends – structural change, servitization, and skill-biased change – using German data from 1975 to 2017. Through a decomposition analysis, we discern their individual impacts on employment shifts, revealing their distinct roles in the German labor market’s evolution. Servitization and skill-biased change significantly influence employment growth alongside ...

Impact of ESG Performance on the Cost of Capital in the Energy, Utilities, and Basic Materials Sectors

This paper explores the presence of an environmental, social, and governance (ESG) premium for firms operating in the energy, utilities, and basic materials sectors. Specifically, we examine the influence of ESG performance on firms’ cost of capital in both debt and equity markets. We apply a measure of the ex ante implied cost of equity and the cost of debt to a global sample of over 24,000 firm-year ...

The Keys to the House - How Wealth Transfers Stratify Homeownership Opportunities

This study investigates how actual and anticipated intergenerational wealth transfers – i.e., inter vivos gifts and inheritances – contribute to inequalities in the transition to homeownership by parental social class. Utilizing discrete-time survival analysis on data from the German Socioeconomic Panel Study (N = 13,018), we find that individuals whose parents were manual workers or service workers ...

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 ...
