Does financial integration affect real exchange rate volatility and cross-country equity market returns correlation?

Existing empirical studies show that financial integration affects the behavior of average excess returns, cross-country equity market returns (EMR) correlations and real exchange rate (RER) volatility. We employ a recently developed two-country model with recursive preferences, frictionless and complete markets and highly correlated long-run innovations to examine whether full financial integration (i.e. full risk-sharing) affects the US-Canada EMR correlation and the US RER volatility, consistently with existing empirical findings. First, full risk-sharing gives rise to a relatively high RER volatility. Second, it induces very strong positive cross-country EMR correlations. Both quantities are higher than those observed in the US-Canada asset pricing data, and increase as the risk-sharing incentive increases. In contrast, “international consumption quantities” are weakly sensitive to changes in the level of aversion to consumption and utility risk.     

Linkages between emerging and developed equity markets: Empirical evidence in the PMG framework

This paper empirically investigates the international equity market causal links between Central and South-Eastern Europe, on the one hand, and developed countries (Western Europe and the United States), on the other hand, over the monthly sample period spanning from October 2000 to September 2012. Unlike previous studies, we use the pooled mean group (PMG) approach of Pesaran et al. (1999), which is suitable to estimate dynamic heterogeneous panels to draw reliable conclusions. After cointegration is found between the stock markets of interest, the PMG estimates show evidence of each market's sensitivity to the fluctuations of the other markets over both the short- and long-run, supporting the feedback hypothesis. The impact of developed markets on emerging markets is more important than that of emerging markets on developed markets and the bidirectional impact is higher between emerging and Western European markets than between these emerging markets and the United States. These conclusions are robust to an alternative specification, which supports the view that the stock markets are closely interlinked. The findings are of great interest and have important implications for policy makers, investors, and practitioners.

The Impact of Brand Equity and the Company's Reputation on Revenues

Abstract

This paper intends to establish the relationships among variables in corporate communications, especially between advertising and public relations, and to form an evaluation model for integrating the effects of brand equity and the company's reputation in the context of integrated marketing communications (IMC). A new approach for integrating the effects of brand equity and the company's reputation was introduced and the IMC evaluation model was specified for testing. The proposed model was tested with existing secondary data. The outcomes indicated that both brand equity and the company's reputation have significant impact on revenues and showed the positive relationship between brand equity and the company's reputation in the proposed model to justify the need of IMC in overall corporate communications.     

精神辩证法之内、外因关系新探——兼与骆郁廷、郝登峰博士商榷

唯物辩证法认为，事物因自身内外部的原因而运动发展。内因与外因作为事物自我运动发展的动力相互依存、互为存在的前提条件；既不存在孤立内因起作用的情况，也不存在孤立外因起作用的情况。因此，精神作为推动事物运动的动力也必然是内因与外因的辩证统一。有精神内因作用也必有精神外因作用；有精神外因作用也必有精神内因作用；孤立精神内因或孤立精神外因单独起作用的情况根本不可能存在。
