In this paper, we test the causal relationship between economic growth and tourism development in the 1995–2012 period using recently developed panel Granger causality tests that allow for country-level heterogeneity, thus leading to more accurate results for the 12 Mediterranean countries. Although results of the Dumitrescu and Hurlin [(2012) testing for Granger non-causality in heterogeneous panels. Economic Modelling, 29(4), 1450–1460] panel Granger causality test show a unidirectional causality from tourism development to economic growth, results of the Croux and Reusens [(2013). Do stock prices contain predictive power for the future economic activity? A Granger causality analysis in the frequency domain. Journal of Macroeconomics, 35, 93–103] panel Granger causality analysis in the frequency domain show that there is a bidirectional temporary and permanent causality between tourism development and economic growth. The bidirectional causality relationship between tourism development and economic growth, which is the main finding of this study, suggests that in order to achieve high economic growth, policy-makers should focus on developing the tourism sector.  相似文献

A large body of literature argues that the characteristics of exports matter for economic growth and development because some goods trigger positive externalities or are subject to increasing returns. Thus, for policy purposes, it is important to know whether a country’s export basket enjoys these productive opportunities. They have been associated with technological content of exports. However, measuring them is not easy. Previous methodologies to account for exports’ technological content used either R&;D data or trade data. The former is used to account for knowledge-intensive activities during the production phase and the latter to identify levels of ‘sophistication’ of exports based on exporting countries’ characteristics. Building on these contributions, this paper combines industry-based and product-based indicators to circumvent some of the shortcomings of the received literature, including the product-industry controversy (i.e. are the actual activities during the production process or the product characteristics what better accounts exports’ technological content?). We use data from Uruguay on direct and indirect R&;D spending from public and private sources and also trade data to build the sophistication index corrected by quality. We contrast our findings with existing methodologies to highlight our contribution.  相似文献

We investigate the driving forces behind the level and the growth rate in real per capita Gross Domestic Product (GDP) in Indonesia. The ultimate reasons and the proximate causes underlying Indonesia's economic growth since the mid-1960s are still unclear. In the literature there have been at least three ways of investigating the driving forces of economic growth in Indonesia, namely: growth accounting system, regression and causality. The difference and improvement in this article is that we employed a two-step bounds testing approach to cointegration, which has not been done before; it uses the endogenous growth model to consider 12 policy variables and two external factors that potentially affect per capita income, this number is more than that has been done before. The empirical results that we obtained using this two-step bounds testing approach help us draw policy implications that if or when implemented would be expected to increase the growth of real per capita income, as well as the welfare of the people of Indonesia. Economic growth in Indonesia is largely driven by government policy, so the ability to increase Indonesia's economic growth rate, in the long run, will largely depend on the implementation of appropriate government policies.  相似文献

Despite knowing the potential effect of social reporting on firms' continuity, there is limited research into the influence of the composition of boards of directors on CSR disclosure. This paper adds to the emerging CSR literature empirical evidence by examining how board composition relates to a firm's social and environmental disclosure as well as the implementation of social policies. Using a sample of FTSE 350 firms for the period 2007–2012, the results show that higher board independence facilitates the conveying of firms' good citizenship image through enhancing societal conscience. The results also show that female participation on boards is favorably affecting CSR engagement and reporting as well as the establishment of ethical policies. Hence, the research suggests that boards with higher female participation and independence boost the legitimacy of CSR reporting. Board gender diversity and independence facilitates directing part of the firm's scarce resources toward value maximizing social projects and subsequent reporting on these.

通过对自然权利相关概念的分析与界定,明确自然权利的提出绝对不是没有现实基础的单纯思辩,而是有一定实际基础的.它的现实基础讲起来很简单,日益恶化的生态危机让人的生存问题开始严峻起来了,一方面人们开始重视人与自然之间的关系问题,开始思索人在自然当中的角色定位问题;另一方面是人与自然之间的冲突问题,即自然权利问题.要解决自然权利的问题,建立人与自然的协调发展,实现人类与自然界关系的全面、协调关系是人类生存与发展的必经之路.  相似文献

This paper adds to the literatures on socially responsible investment (SRI), investment management, regulation of financial services and social accounting by providing a comprehensive survey of investment methods used in SRI products and regulated social reporting in financial services. Australian and New Zealand regulations require issuers of self‐declarative SRI products to provide details on methods used in portfolio construction. Regulators' objectives to standardize the reporting of portfolio construction and thus improve its comparability were identified by examination of parliamentary debates and other public reports. Portfolio construction styles of 86 SRI products managed by 63 financial institutions in Australia and New Zealand were chosen for analysis. Statistical analysis was conducted to identify associations between styles, construction methods and assessment techniques over a four‐year period: 2004–2007. These aspects were further examined in 18 case studies. Over the period, diversity and intensity of construction methods had increased both within and between investment managers. The non‐standard nature of management consultation used in SRI products, marketing needs to distinguish rather than standardize investment methods and the types of information thought relevant to clients did not reconcile easily with the types of information required by regulation. The more recent products in the sample tended to reference market indexes in portfolio construction, separate social considerations from financial considerations and delegate qualitative assessments of invested companies. Consumer policy implications arise from questions bearing on the integrity of information attached to investment products and the effective monitoring of delegated investment processes.

土地出让金在有效利用国土资源、调节收入分配、增加公共财政等方面发挥了积极的作用。但是,分税制改革后地方政府对土地买卖的过分依赖带来的野蛮拆迁、房价虚高等问题也随之成为阻碍城市化进程健康发展的重要因素。如何对土地出让金进行合理征收和科学管理成为当下执政者亟特解决的问题。  相似文献
