We use topic modeling to study research articles in environmental and resource economics journals in the period 2000–2019. Topic modeling based on machine learning allows us to identify and track latent topics in the literature over time and across journals, and further to study the role of different journals in different topics and the changing emphasis on topics in different journals. The most prevalent topics in environmental and resource economics research in this period are growth and sustainable development and theory and methodology. Topics on climate change and energy economics have emerged with the strongest upward trends. When we look at our results across journals, we see that journals have different topical profiles and that many topics mainly appear in one or a few selected journals. Further investigation reveal latent semantic structures across research themes that only the insider would be aware.
This paper reviews and systematizes the empirical research on the nexus between corporate governance (CG) and investments in research and development (R&D) published in leading business, management, economics and finance journals over the past 30 years. We find that CG is key in shaping R&D investments. Moreover, the effects of both firm- and country-level CG are important for both internal and external R&D investments. Drawing on our review, we welcome future studies to examine the effect of the interplay between various CG mechanisms and different types of R&D investments, and possibly identify mediating variables besides the moderating ones. Moreover, we highlight the need for future interdisciplinary studies, as well as investigations of private companies and across developing countries. Whenever causal interpretations are attempted, both sample selection and endogeneity problems should be addressed, along with testing the CG-R&D investment nexus for nonlinear dynamics. The implications of the study for both theory and practice are also discussed. 相似文献
The firm’s investment opportunity set (IOS) reflects the prospective growth opportunities related to physical and human capital investments. IOSs are largely firm specific, embedded in assets-in-place, or generated by experience curves, learning-by-doing, and other similar phenomena. However, the value of an IOS can be destroyed if a firm does not exercise the option to invest. In this study, we theorize that a firm’s ability to invest in R&D is conditional on the availability of a favorable IOS. We test our theoretical propositions in the European business environment using a sample of large publicly traded firms with concentrated ownership. Our findings support the notion that the IOS is a significant determinant of corporate R&D investments, but the magnitude of this effect depends on the identity of the ultimate owner. Specifically, the sensitivity of R&D investments of family- and state-owned corporations is higher to favorable IOS than that of widely held corporations, suggesting these firms are more responsive to favorable IOS than others. By introducing the IOS dimension, our results have interesting implications for both theory and practice. 相似文献
This article considers age and gender differences in the probability and consequences of job mobility in Russia. Little is known about who is mobile and whether mobility impacts wages once the characteristics of movers are controlled for. Results show a gender difference in the likelihood of exit but not promotion. Results also show that promotions have a positive effect only on the wages of young women, but young men's wages are not affected. Further, young men see a significant decrease in wages following an exit, while young women are not affected by firm exit. The article shows that early mobility is particularly important for women, who earn less overall. Results help to understand processes of inequality in wages and conditions that occur due to sorting, and the importance of promotions as ‘life chances’ which lead to ‘career-track jobs’. Gender differences in securing such life chances may help to understand gaps in earnings, which emerge later. 相似文献

AbstractDevelopment strategies followed by many countries in the 20th century bestowed a relevant role to the State. During the 1970s, it all reversed, and free markets became paramount to efficiency. F. von Hayek and the Mount Pelerin Society led the way to eliminate the State as a significant economic player, while P.T. Bauer extended such ideas to development economics, which would eventually give way to the Washington Consensus. Beyond actual results of such policies, it is surprising to see the appeal of Bauer’s theoretical approach, considering that it is constructed disregarding both empirical evidence, as well as the abundant discussion on development that was taking place contemporarily. This article explores the theoretical process of such reversal in development economics theory. 相似文献
Tests of the expectations hypothesis reveal that the slope of the VIX futures term structure predicts the direction but not the magnitude of the evolution of the short-end of the curve, but predicts neither the direction nor the magnitude of short-term changes in the long-end of the curve. Relative value seeking spread trades, constructed to exploit such violations, deliver excess returns with annualized Sharpe ratios equal or greater than those of volatility-writing strategies deployed by VIX ETN's for a majority of the 32 spread trade combinations tested. I demonstrate that profits from beta-neutral variations of the spread trades, which are not compensation for taking on equity downside risk by design, are propagated by inflows of capital into VIX futures markets, after controlling for factors that measure changes in the availability of hedge fund capital, risk appetite, and momentum. At the heart of profits, and by extension the term structure anomalies, is a disproportionally elevated basis propagated by long VIX demand that enters the futures market through ETN channels. 相似文献
Chinese originally migrated to the Russian Far East (RFE) to fill a labor shortage on collective farms. In more recent decades, some Chinese migrants have chosen to lease land from Russian farmers to manage their own farms. Rising soybean prices and the trade war between China and the United States have increased demand for land capable of producing soybeans. Thus, Chinese farmers in the RFE compete for land with Russians. The Chinese also contribute positively to local food security by increasing food availability and accessibility. This study uses an econometric model to analyze the impact of Chinese on local land markets in the RFE. Financial support for Russian farmers by the government depresses their demand for land; rising soybean prices and the employment of Chinese farm workers by Russian farmers encourage farm expansion, resulting in higher land prices. Selling farm produce to Chinese merchants increases the amount of land owned, cultivated, and rented by Russian farmers. 相似文献
We investigate the roots of scientists' perceptions of the impact of their work by examining stable psychological characteristics such as personality traits. An analysis of personality traits highlights the effects of policies related to gender equality, allocation of research time and skills acquisition. It improves our understanding of the conflicts related to scientists’ perceptions of the impact of their research on beneficiaries. For example, conscientiousness increases the perceived impact on clinical beneficiaries, but reduces the perceived impact on industrial beneficiaries. Organizational scientific freedom increases the effects of personality traits on perceived impact on beneficiaries such that scientists affiliated to a university are less likely than colleagues working in other research settings to perceive the simultaneous impact of their work on both industrial and clinical beneficiaries. 相似文献
