投资者关系管理与股权融资成本——来自公司网站投资者关系管理的实证发现

文章以沪市2004年、2005年A股上市公司为研究样本,从信息披露与战略管理两个角度分析上市公司投资者关系管理对企业股权融资成本的影响,结果发现上市公司网站投资者关系指数(IIRI)与股权融资成本显著负相关,进一步检验交流信息质量指标对企业股权融资成本的影响,也发现同样的结果。这表明投资者关系管理活动,特别是加强与投资者之间的战略沟通确实能够起到降低股权融资成本的作用,从而为上市公司主动进行投资者关系管理、监管者推动投资者关系管理活动提供了证据支持。     

Capital Flows to Latin America (2003–17): A Critical Survey from Prebisch’s Business Cycle Theory

ABSTRACT

The economic literature on capital flows to developing countries has shared two important commonalities since the 1990s. Published works (whether they focus on the external situation or stress the domestic determinants of capital flows) tend to assume a beneficial effect of capital inflows, which leads to an improvement of peripheral institutions, whose deficiencies are ostensibly the main cause of economic turmoil and/or failure in attracting capital flows, in continuity with New Institutional Economics. In doing so, mainstream economists deliberately overlook the asymmetric characteristics of the international monetary system and the persisting hegemony of dollar. Raul Prebisch’s pioneering work on business cycles in Latin America provide an alternative view, one capable of amending the existing mainstream literature. On the one hand, Prebisch stressed the destabilizing role of capital inflows on Latin American economies, particularly short-term speculative capital. On the other hand, Prebisch designed a set of counter cyclical monetary policies in order to contrast capital volatility, particularly during downturns. An analysis of stylized facts shows that, when correctly updated, Prebisch’s theory has remarkable explanatory potential when applied to Latin America’s current economic and financial situation.
