Strengthening Gender Justice in a Just Transition: A Research Agenda Based on a Systematic Map of Gender in Coal Transitions

For climate change mitigation, a rapid phase-out of fossil fuels such as coal is necessary. This has far-reaching gender-specific consequences. This paper presents a systematic map of the literature that examines the impact of historical coal phase-out processes on women and their role in these processes. The search process consisted of screening over 3100 abstracts and reading 247 full-text studies. ...

The Role of Energy Storage in the Uptake of Renewable Energy: A Model Comparison Approach

The power sector needs to ensure a rapid transition towards a low-carbon energy system to avoid the dangerous consequences of greenhouse gas emissions. Storage technologies are a promising option to provide the power system with the flexibility required when intermittent renewables are present in the electricity generation mix. This paper focuses on the role of electricity storage in energy systems ...

Air Pollution and the Productivity of High-Skill Labor: Evidence from Court Hearings

Air pollution’s influence on cognitive productivity is a highly relevant and not fully understood economic issue. This study provides evidence of an adverse effect of exposure on the productivity of Mexican judicial workers. The empirical strategy approximates productivity with the length of the hearing and infers causality through instrumental variable panel models. Results show that nitrogen dioxides ...

The Economics of Variable Renewable Energy and Electricity Storage

The transformation of the electricity sector is a central element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and its integration in the ...

Carbon Pricing of Basic Materials: Incentives and Risks for the Value Chain and Consumers

Different options for a reform of the EU Emissions Trading System are discussed to ensure carbon price incentives for mitigation options in the basic materials sector, while minimizing carbon leakage risks. This paper quantifies carbon leakage risks, distributional implications, and additional revenues associated with an import-only border carbon adjustment (BCA), a symmetric (import and export) BCA, ...

Government Spending Multipliers in (Un)certain Times

We estimate the dynamic effects of government spending shocks, using time-varying volatility in US data modeled through a Markov switching process. We find that the average government spending multiplier is significantly and persistently above one, driven by a crowding-in of private consumption and non-residential investment. We rationalize the results empirically through a contemporaneously countercyclical ...

Socioeconomic Position and SARS-CoV-2 Infections: Seroepidemiological Findings from a German Nationwide Dynamic Cohort

Background Evidence on the relationship between socioeconomic position (SEP) and infections with SARS-CoV-2 is still limited as most of the available studies are ecological in nature. This is the first German nationwide study to examine differences in the risk of SARS-CoV-2 infections according to SEP at the individual level.Methods The ‘CORONA-MONITORING bundesweit’ (RKI-SOEP) study is a seroepidemiological ...

The Effect of Early Childhood Education and Care Services on the Integration of Refugee Families

Devising appropriate policy measures to integrate refugees is high on the agenda of many governments. This paper focuses on the integration of families seeking asylum in Germany between 2013 and 2016. Exploiting regional differences in early childhood education and care (ECEC) services and dispersal policies as exogenous sources of variation, as well as controlling for local level heterogeneity that ...

Effects of Decarbonization on the Energy System and Related Employment Effects in South Africa

This paper assesses the impact of decarbonization on the energy system and related employment in South Africa. The cost-minimizing, global energy system model (GENeSYS-MOD) is utilized to project two energy mix scenarios and their associated employment implications at provincial level. While the business as usual (BAU) scenario shows a continuous use of coal capacity in the South African power sector ...

Incubators, Accelerators and Urban Economic Development

We combine theory and evidence on incubator and accelerator programmes and their effects on urban economic development. These structured co-working programmes have grown rapidly. However, a rich descriptive literature reveals little about their impact on participants or surrounding urban areas. We situate programmes in a conceptual framework of co-location tools, theorise objectives and benefits and ...

Loneliness During a Nationwide Lockdown and the Moderating Effect of Extroversion

Loneliness levels were assessed in a longitudinal, nationwide sample (N total = 6,010) collected over the course of the first 3 months of the COVID-19 pandemic in Germany. When in-person social contact restrictions were put in place, loneliness increased significantly compared to prepandemic levels but began to decrease again even before contact restrictions were eased. The loneliness costs were distributed ...

The Development of Life Goals across the Adult Lifespan

ObjectivesLife goals are important organizing units for individual agency in development. On a societal level, they align with age-normative developmental tasks; on the individual level, they guide people’s attempts at shaping their own development. This study investigates the development of life goals across the adult lifespan with a focus on differences regarding gender, parental status, education, ...

Mexico and U.S. Power Systems under Variations in Natural Gas Prices

This study examines the impact of natural gas prices on the power systems of Mexico and the United States. For this, we develop an integrated modeling framework by soft linking three different techno-economic bottom-up models of the power and energy systems, one partial equilibrium model of the natural gas sector, and a partial equilibrium model of the Mexican energy sector. Our results show several ...

Aktuelle Reformvorschläge zum Einkommensteuertarif: Mittelschichten entlasten, hohe Einkommen belasten

Der aktuelle Einkommensteuertarif belastet Mittelschichten und Besserverdienende relativ stark durch den schnellen Anstieg der Progression. Entlastungen durch eine Anhebung des Grundfreibetrags oder eine Abmagerung des Mittelstandsbauchs führen leicht zu Steuerausfällen von höheren zweistelligen Milliardenbeträgen im Jahr. Erhöhungen der Spitzensteuersätze wirken dem entgegen, allerdings sind die Aufkommenspotenziale ...
