I examine the effect of different forms of foreign investment liberalization on risk in emerging equity markets, including international cross-listings and closed-end country funds, and in the domestic equity market as foreign investment restrictions are eliminated. I find that in Latin American markets volatility declines significantly with different forms of foreign investment liberalization, and in Asian markets volatility does not increase significantly. Volatility is driven by domestic factors in South America, but the transmission of volatility from the United States to Mexico increases after liberalization. The market risk exposure increases in Argentina after liberalization, in Chile with an index of American Depositary Receipts, and in Thailand with greater foreign ownership, reducing the diversification benefits of these markets. 相似文献

We examine whether favorable information conveyed by stock split announcements transfers to nonsplitting firms within the same industry. On average, nonsplitting firms' shareholders experience positive and significant abnormal returns at the stock split announcements of their industry counterparts. In addition, industrywide and firm-specific characteristics are important determinants in explaining nonsplitting firms' stock returns. These firms' earnings increase significantly, and the earnings changes are positively related to the stock price reactions. Finally, we find no evidence that investors revise the value of nonsplitting firms because they anticipate a decline in earnings volatility. 相似文献

We examine the spillover wealth effects of the Orange County, California bankruptcy announcement in December 1994 on municipal bonds, municipal bond funds, and bank stocks. This bankruptcy is prominent because of unprecedented losses and because it was caused by a highly leveraged derivatives strategy rather than a shortage of tax revenues and excess spending. We find contagion in the bond market with significantly negative abnormal returns for municipal bond funds without direct exposure to Orange County and for non‐Orange County municipal bonds. In addition, our findings suggest the contagion spills over to the common stocks of investment and commercial banks that deal in or use derivatives; however, the equities of banks unexposed to derivatives are not affected. 相似文献

Abstract. We construct a stylised model of the supply side with goods and labour market imperfections to show that an economy can rationally operate at a low-effort state in which the relationship between output and unemployment is positive. We examine data from the G7 countries over 1960–2001 and find that only German data strongly favour a persistent negative relationship between the level of output and rate of unemployment. The consequence of this is that circumstances exist in which market imperfections could pose serious obstacles to the smooth working of expansionary and/or stabilisation policies and a positive demand shock might have adverse effects on employment. 相似文献

This paper investigates the impact of international collaboration and its characteristics on the quality of the innovation of multinational enterprises (MNEs) in emerging markets. Using a unique dataset of 1428 international and comparable domestic collaboration projects over the 2010–2016 period, it finds that while international innovation collaborations are associated with high innovation quality, cultural distance has a negative effect on collaboration outcomes. Moreover, proximity to the focal firm's overseas R&D centres and the size of expenditure budgets play significant moderating roles in overcoming cultural barriers. Based on the RBV and dynamic capabilities theory, we investigate how firms from emerging markets can acquire these two crucial requisites for innovation. The characteristics of partners and intellectual property (IP) arrangements are also found to have a significant impact on the quality of innovations. 相似文献

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important
paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line,
we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly
top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes
requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with
statistical rank based tests.

从GATT第3条的解释看环境税的合法性——基于“平等对待条款”解释的视角 总被引:1,自引:0,他引:1
王慧 《国际商务-(对外经济贸易大学学报)》2010,(6)
由于环境税会影响一国的产业竞争力,所以采取环境税的国家通常会在相关立法中制定涉外条款来保护本国产业。从GATT/WTO争端解决机制对GATT第3条平等对待条款的解释来看,GATT/WTO争端解决机制倾向于限制各国的环境规制自由,环境保护作为平等对待条款免除对象的可能性不大,环境税涉外在GATT第3条中难以获得合法性地位。 相似文献
