It is well-documented that women and racial and ethnic minorities are underrepresented in the economics profession, relative to both the general population and other academic disciplines. Less is ...known about the socioeconomic diversity of the economics profession. In this paper, we use data on parental education from the Survey of Earned Doctorates to examine the socioeconomic background of US economics PhD recipients, as compared to other disciplines. We find that economics PhD recipients are substantially more likely to have highly educated parents, and less likely to have parents without a college degree, than PhD recipients in other non-economics disciplines. This is true for both US-born PhD recipients and non-US-born PhD recipients, but is particularly stark for the US-born. The gap in socioeconomic diversity between economics and other PhD disciplines has increased over the last five decades, and particularly over the last two decades.
Knowledge is the key factor to promote the development of enterprise innovation ability. Strategic knowledge disclosure is an important strategic means for enterprises to acquire external knowledge ...resources through active disclosure of knowledge. However, under the dual effects of external environmental factors and corporate factors, the impact of strategic knowledge disclosure on corporate innovation performance is still in a “black box” state. Therefore, based on the dual factors of industry competition intensity and enterprise absorptive capacity, this paper selects 158 listed companies in knowledge‐intensive industries as the research object, and uses the fixed effect model to empirically test the impact of strategic knowledge disclosure on enterprise innovation performance. It is found that strategic knowledge disclosure significantly promotes enterprise innovation performance, industry competition intensity negatively regulates the relationship between strategic knowledge disclosure and enterprise innovation performance, and enterprise absorptive capacity positively regulates the relationship between strategic knowledge disclosure and enterprise innovation performance. This paper is helpful to provide practical basis for the implementation of strategic knowledge disclosure and the improvement of enterprise innovation ability under the integrated perspective of external environmental factors and internal factors.
Employing a time series approach, Vector Error Correction Model, we investigate the price discovery in imported natural gas, liquefied natural gas (LNG) and pipeline, markets in China. The ...liberalisation of domestic natural gas markets and China's pricing reforms have induced systematic structural breaks. The present study explores the dynamic interrelationship between imported LNG and pipeline gas prices. Empirical results show that, before the market reforms in 2014, two markets were not cointegrated implying that both prices move somewhat independently. Over the series of market reforms between 2014 and 2019, both markets have started moving together (cointegrated). From winter 2020, LNG price increased abruptly partly due to LNG supply capacities and both prices are not cointegrated. In addition, empirical results show that LNG market is leading the imported natural gas markets in China and pipeline market is the major price adjuster, that is, a lagging market.
Im deutschsprachigen Raum gibt es seit den 2010er Jahren immer mehr Popliteratur in einem anderen Sinne: Autor*innen nämlich, die das popkulturelle Feld zuerst als Musiker*in betreten haben und ...später Bücher publizieren. Diese Feldwechsel sind für Verlage und für die Akteur*innen äußert lukrativ und attraktiv. Die knappe Währung Aufmerksamkeit wird im Übermaß ausgeschüttet, wenn jemand mit einem gewissen Bekanntheitsgrad aufbricht und den literarischen Kampfplatz betritt. Die Beiträger*innen kartographieren das expandierende Feld der popliterarischen Musiker*innenromane und -texte mit besonderem Fokus auf ästhetische Verfahren und Künstler*inneninszenierung. Mit Beiträgen u.a. von Manja Präkels und Hendrik Otremba sowie einem Interview mit Thorsten Nagelschmidt.
Cost-benefit analyses (CBA) are often questioned on the grounds that results depend crucially on uncertain assumptions about the future, and on ethically or methodologically contestable trade-offs ...between different types of benefits. This paper explores the robustness of CBA rankings
of transport investments with respect to two types of uncertainties: relative benefit valuations and scenario assumptions related to car ownership, car characteristics and driving costs. The impact of differentiating the value of time with respect to travel mode and purpose is also studied.
The study concludes that CBA rankings are robust to all of the studied variations.
