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 ...

Life Cycle Environmental Impacts of Electricity from Fossil Fuels in Chile over a Ten-Year Period

This study uses life cycle assessment to evaluate the environmental impacts of electricity generated from fossil fuels in Chile over a ten–year period, from 2004 to 2014. The focus on fossil fuels is highly relevant for Chile because around 60% of electricity currently comes from natural gas, coal and oil. The impacts are first considered at the level of individual technologies, followed by the evaluation ...

Panel Survey Recruitment With or Without Interviewers? Implications for Nonresponse, Panel Consent, and Total Recruitment Bias

Joint Roles of Parenting and Nutritional Status for Child Development: Evidence from Rural Cambodia

Substantial work has demonstrated that early nutrition and home environments, including the degree to which children receive cognitive stimulation and emotional support from parents, play a profound role in influencing early childhood development. Yet, less work has documented the joint influences of parenting and nutritional status on child development among children in the preschool years living ...

Top Incomes in Germany, 1871-2014

This study provides new evidence on top income shares in Germany from industrialization to the present. Income concentration was high in the nineteenth century, dropped sharply after WWI and during the hyperinflation years of the 1920s, then increased rapidly throughout the Nazi period beginning in the 1930s. Following the end of WWII, German top income shares returned to 1920s levels. The German pattern ...

Declining Teen Employment: Minimum Wages, Returns to Schooling, and Immigration

We explore the decline in teen employment in the United States since 2000, which was sharpest for 16–17 year-olds. We consider three main explanatory factors: a rising minimum wage that could reduce employment opportunities for teens and potentially increase the value of investing in schooling; rising returns to schooling; and increasing competition from immigrants that, like the minimum wage, could ...

How to Liberalise Rail Passenger Services? Lessons from European Experience

This paper studies the experience of Europe's three most liberalised railways - Sweden, Germany and Britain - in opening-up rail passenger services to competition by means of competitive tendering, and seeks to draw lessons for countries that are just starting the process, such as France. It also comments on experience of competition in the market in these and other countries (this form of competition ...
