We examine whether a disclosure mandate for greenhouse gas emissions creates stakeholder pressure for firms to subsequently reduce their emissions. For UK-incorporated listed firms such a mandate was adopted in 2013. Using a difference-in-differences design, we find that firms affected by the mandate reduced their emissions – depending on the specification – by an incremental 14-18% relative to a control ...
Das DIW Berlin trauert um seinen langjährigen früheren Abteilungsleiter Dr. Bernhard Seidel. Er starb am vergangenen Wochenende nach kurzer schwerer Krankheit im Alter von 76 Jahren. Seidel trat im Jahr 1969 ins Institut ein und war zunächst Referent für Europa in der damaligen Abteilung „Westliche Industrie- und Entwicklungsländer“. 1992 wurde er Leiter der Forschungsabteilung ...
We combine unique data that include all practitioner health diagnoses based on the International Classification of Diseases (ICD-10) collected from all publicly insured individuals in Germany with a sizable cohort specific pension reform to study the causal effect of an increase in the retirement age on health. For the analysis, we use a cohort specific regression discontinuity design. The...
This study examines the relationship between air quality alerts and school absenteeism in New York City. Examining the effects of the alerts in school attendance is relevant because it helps us understand parents' avoidance behavior in situations of exacerbated exposure to air contaminants. Causality arises by exploiting the deterministic nature of the alerts with regression discontinuity...
Zu den Ergebnissen der heutigen Sitzung des EZB-Rates äußert sich DIW-Präsident Marcel Fratzscher wie folgt:
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. Many “researcher ...
The 2D:4D digit ratio, the ratio of the length of the 2nd digit to the length of the 4th digit, is often considered a proxy for testosterone exposure in utero. A recent study by Nicolaou et al. (2018) reported an association between the left-hand 2D:4D and self-employment (in a sample of about 1,000 adults). In this pre-registered study we replicate these results on a new and larger sample of about ...
In the project, calculations are to be carried out on the return on different forms of old-age provision for three types of individuals: low earners, average earners and high earners. A distinction is made between calculations for the statutory pension insurance (GRV) and for company pensions (BAV). The main aim is to show how different legal regulations in the GRV and BAV that will be effective...
