Toward a Systemic Approach to Energy Transformation in Algeria

This paper examines the drivers of Algeria's energy transformation as well as the cross-cutting issues and challenges in the transformation process. It suggests a framework that accelerates sustainable transformation based on the ideologies of systemic reasoning. Interviews were conducted with 20 energy experts in Algeria, along with a content analysis of policy documents, reports, and previous studies. ...

Tuition Fees and Educational Attainment

Following a landmark court ruling in 2005, more than half of Germany’s universities started charging tuition fees, which were later abolished in a staggered manner. We exploit the fact that even students who were already enrolled had to start paying fees. We show that fees increase study effort and degree completion among these students. However, fees also decrease first-time university enrollment ...

Cognitive Reflection and 2D:4D: Evidence from a Large Population Sample

Bosch-Domènech et al. (2014) reported a negative association between 2D:4D, a suggested marker of prenatal testosterone exposure, and the Cognitive Reflection Test (CRT) in a sample of 623 university students. In this pre-registered study, we test if we can replicate their findings in a general population sample of over 2,500 individuals from Germany. We find no statistically significant association ...

Family Care during the First COVID-19 Lockdown in Germany: Longitudinal Evidence on Consequences for the Well-Being of Caregivers

We examine changes in the well-being of family caregivers during the early phase of the COVID-19 pandemic in Germany, using data from the German Socio-Economic Panel (SOEP) and the SOEP-CoV study. The COVID-19 pandemic posed an extraordinary challenge for family caregivers, as care recipients are a high-risk group requiring special protection, and professional care services were severely cut back. ...

A Collective Blueprint, Not a Crystal Ball: How Expectations and Participation Shape Long-Term Energy Scenarios

The development of energy systems is not a technocratic process but equally shaped by societal and cultural forces. Key instruments in this process are model-based scenarios describing a future energy system. Applying the concept of fictional expectations from social economics, we show how energy scenarios are tools to channel political, economic, and academic efforts into a common direction. To impact ...

Revisiting the Relatedness Hypothesis: The Impact of Merger Relatedness on Acquiring and Rival Firm Value  

Despite intuitive appeal, empirical evidence supporting the relatedness hypothesis has been scant, as it has not been established that related acquisitions generally outperform unrelated acquisitions. In considering the impact of merger relatedness on not only acquiring-firm value – as is standard in the relatedness literature – but also on non-merging rival firm value, we offer an alternative perspective ...

Stranded Nations? Transition Risks and Opportunities towards a Clean Economy

The transition away from a fossil-fuel powered economy towards a cleaner production system will create winners and losers in the global trade system. We compile a list of 'brown' traded products whose use is highly likely to decline if the world is to mitigate climate change, and explore which countries are most at risk of seeing their productive capabilities 'stranded'. Using methods from economic ...

German Financial State Aid during Covid-19 Pandemic: Higher Impact among Digitalized Self-Employed

(In)equality at the Workplace? Differences in Occupational Safety and Health Measures during the Covid-19 Pandemic and Related Employee Health

Auf Basis der Daten einer Sondererhebung des Sozio-oekonomischen Panels zur Covid-19-Pandemie (SOEP-CoV) werden in diesem Beitrag Unterschiede in der Umsetzung verschiedener personenbezogener und organisatorischer Arbeitsschutzmaßnahmen während der Covid-19-Pandemie sowie deren Zusammenhang mit der individuellen Gesundheit von Beschäftigten untersucht. Hierzu wird zunächst ein kurzer Abriss zu sozialen ...

Replacing Gas Boilers with Heat Pumps Is the Fastest Way to Cut German Gas Consumption

The supply security of fossil gas has been disrupted by the Russo-Ukrainian War. Decisions to relocate the production and transport of gas have become so urgent that new long-term contracts are imminent that undermine the Paris Climate Agreement. Here, we simulate how quickly the addition of renewable electricity and the installation of heat pumps can substitute enough gas to reduce supply risk, while ...

Financial Incentives and Antibiotic Prescribing Patterns: Evidence from Dispensing Physicians in a Public Healthcare System

To ensure sufficient access to healthcare in remote areas, some countries allow physicians to directly dispense prescribed drugs through on-site pharmacies. Depending on the medication prescribed, this may pose a significant financial incentive for physicians to over-prescribe. This study, therefore, explored the effect of on-site pharmacies on antibiotic dispensing in a social health insurance system. ...

Technological Relatedness and Industrial Transformation: Introduction to the Special Issue

This article introduces eleven research articles that connect concepts of technological relatedness and diffusion with the transformation of industrial and innovation systems. These studies focus on the role of knowledge spillovers, regional variations in innovation and performance, and the evolution of new technologies, such as green and digital technologies. Regional capabilities and ability to diversify ...

The Price of Natural Gas Dependency: Price Shocks, Inequality, and Public Policy

The 2022 natural gas price spikes across Europe raised concerns regarding their distributional consequences. This paper investigates the distributional effect of price increases between and, in particular, within different income groups in Germany, accounting for different determinants of gas expenditures. The study finds that low-income households are affected the most by the gas price increase. Low-income ...

The Influence of Start-Up Motivation on Entrepreneurial Performance

Predicting entrepreneurial development based on individual and business-related characteristics is a key objective of entrepreneurship research. In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, and ...

The Effect of Increasing Retirement Age on Households’ Savings and Consumption Expenditure

This paper examines how households adjust their savings and consumption expenditure in response to an anticipated increase in the early retirement age (ERA). We examine the 1999 pension reform in Germany, which increased the ERA for women born after 1951 by at least three years. First, we present suggestive evidence that women update their retirement planning in response to the reform. Using the German ...

Monetary Policy, External Instruments, and Heteroskedasticity

We develop a structural vector autoregressive framework that combines external instruments and heteroskedasticity for identification of monetary policy shocks. We show that exploiting both types of information sharpens structural inference, allows testing the relevance and exogeneity condition for instruments separately using likelihood ratio tests, and facilitates the economic interpretation of the ...

Do Women Expect Wage Cuts for Part-Time Work?

I quantify the perceived changes in hourly wage rates associated with working different hours on the same job for a representative sample of female workers. While part-time working women expect significant hourly wage gains from switching to full-time work - 7% on average - full-time workers expect no effect on current wages when switching to part-time, on average. Perceived pecuniary losses from part-time ...

A Tale of Two Data Sets: Comparing German Administrative and Survey Data Using Wage Inequality as an Example

The IAB’s Sample of Integrated Labour Market Biographies (SIAB) and the Socio-Economic Panel (SOEP) are the two data sets most commonly used to analyze wage inequality in Germany. While the SIAB is based on administrative reports by employers to the social security system, the SOEP is a survey data set in which respondents self-report their wages. Both data sources have their specific advantages and ...

Do Rent Controls and Other Tenancy Regulations Affect New Construction? Some Answers from Long-Run Historical Evidence

Optimal Taxation When the Tax Burden Matters

Survey evidence shows that the magnitude of the tax liability plays a role in value judgements about which groups deserve tax breaks. We demonstrate that the German tax-transfer system conflicts with a welfarist inequality averse social planner. It is consistent with a planner who is averse to both inequality and high tax liabilities. The tax-transfer schedule reflects non-welfarist value judgements ...
