This research paper aims to explore the role of FDI inflows and stock market development on the promotion of renewable energy consumption. Furthermore, study investigates the effect of renewable energy consumption on CO2 emissions and economic output across a panel of Brazil, China, India, and South Africa. Study utilizes annual data from 1990 to 2012 and employs various robust panel econometric techniques. The findings confirm that both FDI inflows and stock market development play an important role in promoting renewable energy consumption. The results also reveal that renewable energy consumption helps to mitigate the growth of CO2 emissions and promotes economic development.  相似文献

Data from 1,374 firms across four broad industrial groupings are used to assess the contribution that real (adaptation) options make to overall equity values. The analysis indicates that real (adaptation) options make a significant contribution to the equity value of firms with a market to book ratio (of equity) of around unity or less. As the market to book ratio grows beyond this level, however, the contribution made by real (adaptation) options decays quickly away and equity values are mainly comprised of the present value of the dividends that firms are expected to pay. This means that for around one in every five of the firms in our sample real (adaptation) options make a significant contribution to overall equity value. Thus, while linear equity valuation models would seem to be appropriate for the substantial majority of firms on which our sample is based, there is a sizeable minority of firms where real (adaptation) options have a significant impact on equity values. For this latter group of firms there will be a non-linear relationship between equity value and its determining variables. This has important implications for the regression procedures that are applied in this area of accounting research.  相似文献

Managerial value systems along with individualism-collectivism concepts were examined among 768 managers in Iran. The sample was randomly selected from state, private, and mixed organizations. The participants ranked conformist and sociocentric values high. In addition, the participants displayed a high tendency toward collectivism and a weak commitment to individualism. Furthermore, existential value was highly correlated with individualism-collectivism measures.  相似文献

China's economic ascendance over the past two decades has generatedripple effects in the world economy. Its search for naturalresources to satisfy the demands of industrialization has ledit to Sub-Saharan Africa. Trade between China and Africa in2006 totaled more than $50 billion, with Chinese companies importingoil from Angola and Sudan, timber from Central Africa, and copperfrom Zambia. Demand from China has contributed to an upwardswing in prices, particularly for oil and metals from Africa,and has given a boost to real GDP in Sub-Saharan Africa. Chineseaid and investment in infrastructure are bringing desperatelyneeded capital to the continent. At the same time, however,strong Chinese demand for oil is contributing to an increasein the import bill for many oil-importing Sub-Saharan Africancountries, and its exports of low-cost textiles, while benefitingAfrican consumers, is threatening to displace local production.China poses a challenge to good governance and macroeconomicmanagement in Africa because of the potential Dutch diseaseimplications of commodity booms. China presents both an opportunityfor Africa to reduce its marginalization from the global economyand a challenge for it to effectively harness the influx ofresources to promote poverty-reducing economic development athome.

This paper analyses the impact of news, oil prices, and international financial market developments on daily returns on Russian bond and stock markets. First, regarding returns, energy news affects returns, while news from the war in Chechnya is not significant. Market volatility does not appear to be sensitive to either type of news. Second, a significant effect of the growth in oil prices on Russian stock returns is detected. Third, the international influence on Russian financial markets depends upon the degree of financial liberalization. The higher the degree of financial liberalization, the stronger is the impact of US stock returns on Russian financial markets. In addition, banking reform and interest rate liberalization efforts seem to dictate the globalization of Russian stock markets, while it is the progress in liberalizing securities markets and non‐bank financial institutions that matters more for the globalization of Russian bond markets.  相似文献

Information flows within and across sectors in Chinese stock markets   总被引:1,自引:0,他引:1  
We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.  相似文献

Estimation of the scale matrix of a multivariate t-model under entropy loss   总被引:7,自引:0,他引:7  
This paper deals with the estimation of the scale matrix of a multivariatet-model with unknown location vector and scale matrix to improve upon the usual estimators based on the sample sum of product matrix. The well-known results of the estimation of the scale matrix of the multivariate normal model under the assumption of entropy loss function have been generalized to that of a multivariatet-model. The paper is based on the first author’s unpublished Ph.D. dissertation ‘Estimation of the Scale Matrix of a Multivariate T-model’, University of Western Ontario, Canada.

Several optimum non-parametric tests for heteroscedasticity are proposed and studied along with the tests introduced in the literature in terms of power and robustness properties. It is found that all tests are reasonably robust to the Ordinary Least Squares (OLS) residual estimates, number and character of the regressors. Only a few are robust to both the distributional and independence assumptions about the errors. The power of tests can be improved with the OLS residual estimates, the increased sample size and the variability of the regressors. It can be substantially reduced if the observations are not normally distributed, and may increase or decrease if the errors are dependent. Each test is optimum to detect a specific form of heteroscedasticity and a serious power loss may occur if the underlying heteroscedasticity assumption in the data generation deviates from it.  相似文献

We report a generalization of Aumann's (1966) existence theorem to economies without ordered preferences and with externalities in consumption. Our work can alternatively be viewed as a generalization of the Shafer–Sonnenschein (1975) theorem to economies with a continuum of agents.  相似文献
