Sociohistorical Change in Urban Older Adults’ Perceived Speed of Time and Time Pressure

ObjectivesPerceptions of time are shaped by sociohistorical factors. Specifically, economic growth and modernization often engender a sense of acceleration. Research has primarily focused on one time perception dimension (perceived time pressure) in one subpopulation (working-age adults), but it is not clear whether historical changes extend to other dimensions (e.g., perceived speed of time) and other ...

Wagner, Mitglied im Sachverständigenrat für Verbraucherfragen, stellt aus seiner persönlichen Sicht ausgewählte Analysen, Ergebnisse und Empfehlungen vor. Über das Gutachten hinausgehend wird auch auf relevante Ereignisse hingewiesen, die nach Abschluss ...

Merger Efficiency Gains: Evidence from a Large Transport Merger in France

Many industries are seeing an increase in concentration, leading to a discussion on the effectiveness of horizontal merger enforcement. The policy debate shows that one of the key arguments put forward when supporting potential mergers is the possibility of realization of merger efficiency gains, specifically in the transport industry. Yet, there exists little empirical evidence on the actual effects ...

Panel Data in Research on Mobility and Migration: A Review of Recent Advances

Panel data has become the gold standard for causal assessments of complex human behaviour in quantitative social science. The objective of this review is to examine and discuss how panel data and related methods contribute to the identification of causal relationships in spatial mobility research. We illustrate this by providing a succinct overview of recent progress in spatial mobility research, drawing ...

Exchange Rates, Foreign Currency Exposure and Sovereign Risk

We quantify the causal link between exchange rate movements and sovereign risk of 16 major emerging market economies (EMEs) by means of structural vector autoregressive models (SVARs) and conditional on data from 10/2004 through 12/2016. We apply a novel data-based identification approach of the structural shocks that allows to account for the complex interrelations within the triad of exchange rates, ...

To Ban or Not to Ban Carbon-Intensive Materials: A Legal and Administrative Assessment of Product Carbon Requirements

By setting near-zero-emission requirements for the production of certain products to be sold on the European single market (product carbon requirements, PCRs), the European Union could accelerate the phase-out of carbon-intensive production processes.The announcement of such requirements would send a signal to producers,financing institutions and other relevant stakeholders, thus incentivizing them ...

Publishing in Small Business Economics: An Entrepreneurship Journal

Publishing entrepreneurship research is not just important but challenging. Longstanding experts in the field can provide helpful advice. As borders between academic fields blur, research fields are increasingly global in their perspective, knowledge, and findings, thus enabling robust participation in research fields at a scale previously unimaginable. Drawing on the experience, insights, and perspectives ...

COVID-19: a Crisis of the Female Self-Employed

We investigate how the economic consequences of the pandemic and the government-mandated measures to contain its spread affect the self-employed — particularly women — in Germany. For our analysis, we use representative, real-time survey data in which respondents were asked about their situation during the COVID-19 pandemic. Our findings indicate that among the self-employed, who generally face a higher ...

An Open Tool for Creating Battery-Electric Vehicle Time Series from Empirical Data, emobpy

There is substantial research interest in how future fleets of battery-electric vehicles will interact with the power sector. Various types of energy models are used for respective analyses. They depend on meaningful input parameters, in particular time series of vehicle mobility, driving electricity consumption, grid availability, or grid electricity demand. As the availability of such data is highly ...

Generation Y: Do Millennials Need a Partner to Be Happy?

IntroductionEmpirical evidence on Ronald Inglehart's theory of value change shows that subsequent generations show a decline in values of physical and economic security (materialism) in favor of an increase in values of self-expression and autonomy (postmaterialism).MethodsWe investigate in a pre-registered study whether Inglehart's theory also applies to partnership, such that millennials think less ...

2D:4D Does Not Predict Economic Preferences: Evidence from a Large, Representative Sample

The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. However, ...

Heteroscedastic Proxy Vector Autoregressions

In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroscedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption ...

How Often Have You Felt Disadvantaged? Explaining Perceived Discrimination

Im Rahmen einer Längsschnittanalyse des sozio-oekonomischen Panels gehen wir der Frage nach, wie sich Diskriminierungswahrnehmungen von Einwanderern und ihren Nachkommen im Laufe des Integrationsprozesses verändern. Insgesamt betrachtet fühlen sich Migrantinnen und Migranten, deren Integration weiter fortgeschritten ist, seltener aufgrund ihrer Herkunft benachteiligt. Allerdings zeigen gruppenspezifische ...

Location, Location, Location: The Role of Objective Neighborhood Characteristics for Perceptions of Control

Introduction: Control beliefs can protect against age-related declines in functioning. It is unclear whether neighborhood characteristics shape how much control people perceive over their life. This article studies associations of neighborhood characteristics with control beliefs of residents of a diverse metropolitan area (Berlin, Germany). Methods: We combine self-report data about perceptions of ...

A Green COVID-19 Recovery of the EU Basic Materials Sector: Identifying Potentials, Barriers and Policy Solutions

This paper explores climate-friendly projects that could be part of the COVID-19 recovery while jump-starting the transition of the European basic materials industry. Findings from a literature review on technology options in advanced development stages for climate-friendly production, enhanced sorting, and recycling of steel, cement, aluminium, and plastics, are combined with insights from interviews ...

Freedom Gas to Europe: Scenarios Analyzed Using the Global Gas Model

State-of-the-art, open access numerical modeling of imperfectly competitive energy markets offers a sound and transparent way to address topical research questions in energy and commodity markets. We use an open access equilibrium model, the Global Gas Model (GGM), and sector-specific, politically motivated scenarios to investigate the prospects for sales of liquefied natural gas (LNG) from the U.S. ...

Investing into Third Generation Nuclear Power Plants: Review of Recent Trends and Analysis of Future Investments Using Monte Carlo Simulation

This paper provides a review of trends in third generation nuclear power plants, and analyzes current and future nuclear power plant investments using Monte Carlo simulations of economic indicators. We first review global trends of nuclear power plant investments, including technical as well as economic trends. The review suggests that cost escalations in the sector observed in previous research continue ...

Age Differences in Deliberate Ignorance

People sometimes choose to remain ignorant, even when information comes at low marginal costs and promises high utility. To investigate whether older adults enlist deliberate ignorance more than younger adults, potentially as an emotion-regulation tool, we presented a representative sample of 1,910 residents of Germany with 13 scenarios in which knowledge could result in substantial gains or losses. ...
