The emergence of macroprudential policies, implemented by central banks as a means of promoting financial stability, has raised many questions regarding the interaction between monetary and macroprudential policies. Given the limited number of studies available, this paper sheds light on this issue by providing a critical and systematic review of the literature. To this end, we divide the theoretical and empirical studies into two broad channels of borrowers – consisting of the cost of funds and the collateral constraint – and financial intermediaries – consisting of risk‐taking and payment systems. In spite of the existing ambiguity surrounding coordination issues between monetary and macroprudential policies, it is argued that monetary policy alone is not sufficient to maintain macroeconomic and financial stability. Hence, macroprudential policies are needed to supplement monetary. In addition, we find that the role of the exchange rate is critical in the implementation of monetary and macroprudential policies in emerging markets, while volatile capital flows pose another challenge. In so far as how the arrangement of monetary and macroprudential policies varies across countries, key theoretical and policy implications have been identified. 相似文献

校本方面的研究关注到了教育本质的回归,但对个体的关注尚存在不足。作为校本走向生本的过渡,班本教育的相关研究源于"人是发展的根本目的""因材施教""和谐师生观"等教育理念。梳理相关文献发现,班本研究尚处于起步阶段,无论是理论还是实践方面都有待充实。针对如何更好地实施班本教育,有必要对班级授课制以及传统班级管理管理的相关问题进行研究与探讨。 相似文献

This study performs the first citation-based systematic literature review of the tourism-growth nexus. The citation analysis provides a bird's eye view of this literature, which, in turn, identifies the sources of knowledge in terms of most influential journals, authors, and articles. A detailed content analysis of 100 most influential papers has been generated on the nature of the study, variables used, country of analysis, type of analysis, the methodology, and the direction of causality. In total, 284 papers were found relevant in the Scopus database using a comprehensive list of keywords. The citation analysis reveals that Tourism Management is the leading journal with a total of 2527 citation counts, whereas Tourism Economics is the leading journal with a total of 41 publications on this topic. Juan Gabriel Brida is the most prolific author, whereas Lee and Chang (2008) is recognized as the most influential paper. The content analysis reveals that 58% have applied time series, and 38% have used panel data analysis. Tourism causing growth is the leading result of both time-series and panel studies. International tourism receipts/earnings/expenditure and the number of international tourist arrivals are the most widely used variables to measure tourism. 相似文献

对于商业银行非利息收入的研究,国内外学者有两种截然不同的观点,即非利息收入的增加有利于减少商业银行的经营风险,或增加盈利的波动。这一分歧出现的原因在于实证分析中对非利息收入的界定、研究方法、考核标准、数据来源的不同。针对现阶段我国非利息收入与利息收入的关联性趋势以及非利息收入自身的波动性及周期性特点,我国商业银行应从明晰利息收入与非利息收入的界限、调整非利息收入的结构以及加强外部金融监管三个方面加以应对。 相似文献

《Research in Accounting Regulation》2014,26(1):118-131
Audits and auditors are regulated to uphold audit quality, thus regulation is important to the public interest and clearly impacts firms and CPAs. Moreover, the reach of audit regulation has expanded greatly in the last decade with the establishment of the Public Company Accounting Oversight Board (PCAOB). Recent research and calls from the profession point to enhancing the coverage of audit regulation in the accounting curriculum so that students understand the consequences of failing to adhere to professional standards. In this paper, we propose regulatory content for inclusion in the curriculum, we survey and catalog existing auditing textbooks and other educational materials for regulatory content, and we suggest flexible alternatives for incorporating this topic into the curriculum. It is our hope that, with these resources, faculty can more effectively include audit regulation in the classroom and achieve a high level of student comprehension and learning on the topic. 相似文献
