Drivers of Renewable Technology Adoption in the Household Sector

Using data from the German Socio-Economic Panel, we undertake a simultaneous assessment of the importance of factors that are individually found to be significant for the adoption of renewable energy systems by households but are not yet tested jointly. These are sociodemographic and housing characteristics, environmental concern, personality traits, and economic factors; i.e. the expected costs of ...

Analyzing Climate and Energy Policy Integration: The Case of the Mexican Energy Transition

One of the main challenges faced by climate policy makers today is to design and implement policies capable of transferring climate policy goals into sectoral actions towards transformational pathways. Hence, climate policies need to be of cross-cutting character, lead to coherence with sectoral goals and reconcile diverging sectoral interests. Against this background, Mexico has undertaken significant ...

Anticipating Global Energy, Climate and Policy in 2055: Constructing Qualitative and Quantitative Narratives

This study presents a set of novel and multidisciplinary scenarios (‘narratives’) that provide insight into four distinct and diverging yet plausible worlds. They combine qualitative and quantitative elements in order to reflect the interlinked and complex nature of energy and climate. We use the STEMPLE+ framework to include social, technological, economic, military (security), political, environmental, ...

Pathways for Germany’s Low-Carbon Energy Transformation Towards 2050

Like many other countries, Germany has defined goals to reduce its CO2-emissions following the Paris Agreement of the 21st Conference of the Parties (COP). The first successes in decarbonizing the electricity sector were already achieved under the German Energiewende. However, further steps in this direction, also concerning the heat and transport sectors, have stalled. This paper describes three possible ...

The Effect of Peer Observation on Consumption Choices: Evidence from a Lab-In-Field Experiment

We investigate the impact of peer observation on consumption decisions using a lab-in-field experiment. Respondents make consumption decisions either alone or under peer observation. We find evidence for peer effects. We are able to study these further by looking into the mechanism and performing detailed heterogeneity analysis. Concerning the mechanisms, we find evidence for an information channel. ...

The Effects of Conflict on Fertility: Evidence from the Genocide in Rwanda

Our study analyzes the fertility effects of the 1994 genocide in Rwanda. We study the effects of violence on both the duration time to the first birth in the early post-genocide period and on the total number of post-genocide births per woman up to 15 years following the conflict. We use individual-level data from Demographic and Health Surveys, estimating survival and count data models. This article ...

Inferring Floor Area Ratio Thresholds for the Delineation of City Centers Based on Cognitive Perception

The morphology of today’s cities is the result of historic urban developments and on-going urban transformation resulting in complex urban spatial structures. While functionally as well as spatially, cities are structured into sub-units such as the city center, business districts, residential areas or industrial and commercial zones, their precise localization in the geographic space is sometimes difficult. ...

Cohort Differences in Adult-Life Trajectories of Internal and External Control Beliefs: A Tale of More and Better Maintained Internal Control and Fewer External Constraints

Lifespan theory posits that socio-historical contexts shape individual development. Inline with this proposition, cohort differences favoring later-born cohorts have beenwidely documented for cognition and health. However, little is known about historicalchange in how key resources of psychosocial functioning such as control beliefsdevelop in old age. We pooled data from three independent samples: ...

Sustainable Finance: Political Challenges of Development and Implementation of Framework Conditions

According to the 2015 Paris Agreement, a long-term goal is the commitment to “making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.” Reconciling climate change objectives and financial flows is an enormous challenge in the 21st century. States in general and Germany in particular have various instruments at their disposal to initiate ...

Macroeconomic Effects of Government Spending: The Great Recession Was (Really) Different

We estimate the effect of government spending shocks on the U.S. economy with a time‐varying parameter vector autoregression. The recent Great Recession period appears to be characterized by uniquely large impulse responses of output to fiscal shocks. Moreover, the particularity of this period is underlined by highly unusual responses of several other variables. The pattern of fiscal shock responses ...

The Structure, Drivers and Policy Implications of the European Carbon Footprint

Policy to reduce the European Union’s (EU) carbon footprint needs to be grounded in an understanding of the structure and drivers of both the domestic and internationally traded components. Here we analyse consumption-based emission accounts (for the main greenhouse gases (GHGs)) for the EU, focusing on understanding sectoral contributions and what changes have been observed over the last two decades, ...

Transporting and Storing High-Level Nuclear Waste in the U.S. Insights from a Mathematical Model

The nuclear industry in the United States of America has accumulated about 70,000 metric tons of high-level nuclear waste over the past decades; at present, this waste is temporarily stored close to the nuclear power plants. The industry and the Department of Energy are now facing two related challenges: (i) will a permanent geological repository, e.g., Yucca Mountain, become available in the future, ...

The Social Integration of Lesbians, Gay Men and Bisexuals: Exploring the Role of the Municipal Context

This paper examines possible differences between lesbians, gay men and bisexuals (LGBs) compared to heterosexuals with respect to their integration into the residential neighbourhood. By means of a multi-level analysis, we examine if there is a gap in social integration between LGBs compared to heterosexuals, and if so, to what extent municipality characteristics can account for variations in this ...

Wie (un)gerecht ist die Einkommensverteilung in Deutschland?

Angesichts steigender Einkommensunterschiede verweisen Vertreter einer ungleichheitskritischen Position auf gesellschaftsgefährdende Folgen von Ungleichheit und fordern eine Reduzierung der Einkommensungleichheit. Ein solch pauschaler Zusammenhang zwischen Ungleichheit und negativen gesellschaftlichen Folgen ist hingegen empirisch nicht belegt. Dieser Beitrag nahm dies zum Ausgangspunkt und untersuchte ...

The Death Spiral of Coal in the U.S. Will Changes in U.S. Policy Turn the Tide?

The administration of U.S. President Donald Trump has promised to stop the ongoing spiralling down of the U.S. coal industry. We discuss the origins of the decline and assess the effects of policy interventions by the Trump administration. We find that, with fierce competition from natural gas and renewables, a further decrease of coal consumption must be expected by the old and inefficient U.S. coal-fired ...

The Impact of the German Minimum Wage on Individual Wages and Monthly Earnings

This paper evaluates the short-run impact of the introduction of a statutory minimum wage in Germany on the hourly wages and monthly earnings of workers targeted by the reform. We first provide detailed descriptive evidence of changes to the wage structure in particular at the bottom of the distribution and distinguish between trends for regularly employed and marginally employed workers. In the causal ...

The Individual in Context(s): Research Potentials of the Socio-Economic Panel Study (SOEP) in Sociology

The German Socio-Economic Panel (SOEP) study is a rich resource for sociologists, mainly because it offers direct measures of respondents’ contexts. The SOEP data provide (i) information retrieved from individuals themselves, (ii) direct information retrieved from their parents, partners, and organizations, (iii) prospectively collected information on past characteristics, and (iv) regional and spatial ...

The Impact of Implementing a Consumption Charge on Carbon-Intensive Materials in Europe

The production of basic materials accounts for around 25% of global greenhouse gas emissions. Existing measures to reduce emissions from industry are limited due to a combination of competitiveness concerns and a lack of technological options available to producers. In this paper, we assess the possibility of implementing a materials charge to reduce demand for basic industrial products and, hence, ...

Analyzing 21st Century Video Data on Situational Dynamics: Issues and Challenges in Video Data Analysis

Since the turn of the millennium researchers have access to an ever-increasing pool of novel types of video recordings. People use camcorders, mobile phone cameras, and even drones to film and photograph social life, and many public spaces are under video surveillance. More and more sociologists, psychologists, education researchers, and criminologists rely on such visuals to observe and analyze social ...
