The panel data analysis points to economic and social factors contributing to NOx, PM2.5, PM10, SO2, and VOCs in China’s 31 provinces. The spatial correlation analysis using Global and Local Moran’s I values indicates the existence of a significant and positive spatial autocorrelation with respect to environment, economy and energy, and the high spatial correlation is evident in the eastern region, covering the northern part of Yangtze River Delta, Huaihai Economic Zone, and the lower reaches of the Yellow River Economic Belt. The empirical estimation is performed through spatial lag and spatial Durbin models. All emitted air pollutants in 31 provinces have significant spatial dependence and strong spillover effects. There is an inverted U-shaped relationship between emitted air pollutants (NOx, PM10, VOCs, and PM2.5) and per capita GDP, which follows the EKC hypothesis. The relationship between SO2 and per capita GDP does not follow the EKC hypothesis. There is a positive relationship between pollutant emissions and coal consumption, which is consistent with current studies for various countries like Canada, Denmark, UK and US and regions like New York State. However, the effects of science and technology investment on air pollutants are mostly positive, which is not as policy expected. 相似文献
The empirical literature is replete with evidence that budget deficits and government debt affect (traditional view) or do not appreciably affect (Ricardian equivalence) private consumption. However, the validity of the relative empirical estimates can be questioned to the extent that they do not adequately distinguish among countries with varying levels of indebtedness. The present paper attempts to address this problem by using Johansen's cointegration technique and by sorting the sample countries into groups, according to the ratio of debt to GDP. The empirical evidence generated finds support for the debt-illusion hypothesis as a means of expounding variations in consumers' behaviour among countries with varying degrees of indebtedness. 相似文献
This paper investigates the impact of governance mechanisms on small and medium‐sized enterprise (SME) cash holdings from 2000 to 2009, employing static and dynamic panel data analyses. We find no evidence that firm governance index and insider ownership affect cash holdings. This might indicate that governance mechanisms in SMEs are relatively weak. We also report that chief executive officer compensation has a positive effect on cash holdings. Firm‐specific factors such as firm size, leverage, and liquidity negatively affect cash holdings, whereas the research and development ratio and operating risk are positively associated with them. Finally, SMEs have target cash holdings and adjust to these. 相似文献
The study examines whether corporate governance mechanisms and the compliance with good governance practice are related to cash dividends. In particular, the study assesses the effect of institutional ownership and board structure on the decision to pay cash dividends. A study on UK firms is interesting because firms are expected to voluntarily structure governance mechanisms based on their own needs. We find that institutional owners positively affect cash dividend payments, suggesting that UK institutions are effective in forcing firms to disgorge cash. There is limited evidence that independent directors affect the cash dividends. The results also show that firm specifics affect the cash dividends, namely, business risk, firm size, and leverage ratio. The results are consistent across several robustness checks. 相似文献
China's corporate governance reform offers an interesting context for investigating the determinants of board size and independence. Analysing a large panel dataset from 1999 to 2003, we find that Chinese board size is primarily driven by firm complexity; board independence is mainly driven by regulation. Some governance factors newly introduced in this study also have a significant impact. For example, board independence is negatively associated with the size of supervisory board and state ownership. The findings have important implications and provide new insights into the subject. 相似文献
This paper investigates corporate cash holdings in developing countries. In particular, we look into the effect of capital structure and dividend policy on cash holdings in Brazil, Russia, India, and China and compare our results with a control sample from the US and the UK. Our sample contains 1992 firms across these countries for the period 2002–2008. We employ Instrumental Variables analysis to control for the endogeneity of the financial policies (cash holdings, capital structure, and dividend policy). Our results show some evidence that capital structure and dividend policy affect cash holdings. There are similarities between developed and developing countries on the factors determining corporate cash holdings. The results of our cross-country model provide evidence that capital structure, dividend policy, and firm size are important factors in determining cash holdings. Finally, we show that firms operating in countries with low shareholder protection hold more cash. 相似文献
This study offers foundational insights into the ways in which perceptions of different interview media—principally, face‐to‐face, telephone and videoconferencing channels of communication—may influence researcher choices and practices. Informed by the reflections of 23 senior accounting researchers, our evidence identifies a duality of practices in the usage of different interviewing media, influenced primarily through the role played by experience, which informs perceptions upon which practices are based. We discuss this duality of practices in terms of information richness theory and channel expansion theory and offer further insights into the factors that influence and shape researchers’ perceptions of the contextual suitability of particular media available to interview‐based accounting research. 相似文献
Background: A 3-month long treatment of paliperidone palmitate (PP3M) has been introduced as an option for treating schizophrenia. Its cost-effectiveness in Spain has not been established.
Aims: To compare the costs and effects of PP3M compared with once-monthly paliperidone (PP1M) from the payer perspective in Spain.
Methods: This study used the recently published trial by Savitz et al. as a core model over 1 year. Additional data were derived from the literature. Costs in 2016 Euros were obtained from official lists and utilities from Osborne et al. The authors conducted both cost-utility and cost-effectiveness analyses. For the former, the incremental cost per quality-adjusted life-year (QALY) gained was calculated. For the latter, the outcomes were relapses and hospitalizations avoided. To assure the robustness of the analyses, a series of 1-way and probability sensitivity analyses were conducted.
Results: The expected cost was lower with PP3M (4,780€) compared with PP1M (5,244€). PP3M had the fewest relapses (0.080 vs 0.161), hospitalizations (0.034 v.s 0.065), and emergency room visits (0.045 v.s 0.096) and the most QALYs (0.677 v.s 0.625). In both cost-effectiveness and cost-utility analyses, PP3M dominated PP1M. Sensitivity analyses confirmed base case findings. For the primary analysis (cost-utility), PP3M dominated PP1M in 46.9% of 10,000 simulations and was cost-effective at a threshold of 30,000€/QALY gained.
Conclusions: PP3M dominated PP1M in all analyses and was, therefore, cost-effective for treating chronic relapsing schizophrenia in Spain. For patients who require long-acting therapy, PP3M appears to be a good alternative anti-psychotic treatment. 相似文献
