Gender Pay Gap in American CFOs: Theory and Evidence
Bill Francis, Iftekhar Hasan, Gayane Hovakimian, Zenu Sharma
Journal of Corporate Finance,
June
2023
Abstract
Studies document persistent unexplained gender-based wage gap in labor markets. At the executive level, where skill and education are similar, career interruptions and differences in risk preferences primarily explain the extant gender-based pay gap. This study focuses on CFO compensation contracts of Execucomp firms (1992–2020) and finds no gender-based pay gap. This paper offers several explanations for this phenomenon, such as novel evidence on the risk preferences of females with financial expertise and changes in the social and regulatory climate.

Evidence-based Support for Adaptation Policies in Emerging Economies

No. 2,
2023
Abstract
In recent years, the impacts of climate change become increasingly evident, both in magnitude and frequency. The design and implementation of adequate climate adaptation policies play an important role in the macroeconomic policy discourse to assess the impact of climate change on regional and sectoral economic growth. We propose different modelling approaches to quantify the socio-economic impacts of climate change and design specific adaptations in three emerging market economies (Kazakhstan, Georgia and Vietnam) which belong to the areas that are heavily exposed to climate change. A Dynamic General Equilibrium (DGE) model has been used for Vietnam and economy-energy-emission (E3) models for the other two countries. Our modelling results show how different climate hazards impact the economy up to the year 2050. Adaptation measures in particular in the agricultural sector have positive implications for the gross domestic product (GDP). However, some adaptation measures can even increase greenhouse gas emissions. In addition, the focus on GDP as the main indicator to evaluate policy measures can produce welfare-reducing policy decisions.

European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Journal of the European Economic Association,
No. 2,
2023
Abstract
This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Stellungnahme „Übergreifende Kostenbetrachtung der Auswirkungen des Klimawandels in Schleswig-Holstein“
Katja Heinisch, Oliver Holtemöller, Christoph Schult
IWH Policy Notes,
No. 1,
2023
Abstract
anlässlich der Anhörung im Umwelt- und Agrarausschuss des Schleswig-Holsteinischen Landtags ‒ Antrag der Fraktion der SPD, Drucksache 20/414
Der Klimawandel in Schleswig-Holstein führt zu Veränderungen in Umwelt, Wirtschaft und Arbeitswelt, und er hat Auswirkungen auf die Gesundheit der Menschen. Der wissenschaftliche Konsens geht davon aus, dass die sozioökonomischen und ökologischen Effekte des Klimawandels weltweit überwiegend negativ sein werden. Aus diesem Grund schreibt das Klimaschutzgesetz vor, dass die deutschen Treibhausgasemissionen bis zum Jahr 2030 um mindestens 65% und bis zum Jahr 2040 um mindestens 88% reduziert werden sollen; bis zum Jahr 2045 soll Klimaneutralität in Deutschland erreicht werden. Schleswig-Holstein hat eigene Klimaschutzziele und Maßnahmen eingeführt. Unsicherheiten bestehen jedoch hinsichtlich der nationalen und regionalen Kosten des Klimawandels. Bisherige Studien deuten darauf hin, dass in der zweiten Hälfte des
21. Jahrhunderts in Deutschland die jährlichen Verluste des Bruttoinlandsprodukts unter einem Prozent liegen werden. Zur Plausibilisierung dieser Zahl ist es notwendig, eine transparente und replizierbare Klimawandelfolgenabschätzung für Schleswig-Holstein vorzunehmen. Es wird daher empfohlen, dem Antrag zuzustimmen.
