This study investigates the impact of media on analysts’ herding behavior when making stock recommendations. We find three main results. First, we find that analysts herd less when stocks are covered more in the media. Second, when the firm has negative media sentiment, analysts tend to herd more. Third, higher disagreement in the media is associated with a higher tendency to herd among analysts. These findings are robust to the confounding effect of news flows on returns as well as to alternative explanations. In addition, we find that the effect of media on the herding behavior is conditional on analyst characteristics.

We examine the determinants of price discovery for Canadian firms cross-listed on the main US stock exchanges over the period 1996–2011. Sampling at a one-minute frequency, we compute Gonzalo and Granger Component Shares (CS) and employ a system GMM approach to control for persistence in price discovery and endogeneity between CS and its determinants. We find that price discovery is highly persistent and that there is strong evidence of simultaneity between CS and its determinants. We conclude that lower relative spreads and higher relative trading activity increase an exchange’s contribution to price discovery. We also document that it is small trades that drive price discovery, particularly since the introduction of decimalization.

This paper investigates the role of political crises in explaining the degree of stock market integration in emerging markets over the period 1991–2006. Using the International Crisis Behavior database, which contains detailed information on political crises around the world, and employing data on more than 15,500 firms, we assess whether political crises affect stock market integration in 19 emerging markets in South and East Asia, Latin America, and Central and Eastern Europe. We conclude that crises with certain characteristics generally reduce the level of stock market integration in these regions. In particular, the beginning of a political crisis, its severity, the involvement of the US in the conflict, and the number of parties involved in a crisis all have impacts on the level of stock market integration in these markets.

This paper studies the dynamics of price discovery for markets with bilateral cross-listings. Using a sample of four Australian stocks cross-listed in New Zealand and five New Zealand stocks cross-listed in Australia for the period January 2002 to December 2007, we assess Hasbrouck (1995) information shares and Grammig et al. (2005) conditional information shares over time. We observe that in both cases the home market is dominant in terms of price discovery. However, when studying price discovery over time, we find that the importance of the Australian market (the larger of the two markets) is increasing for both Australian and New Zealand domiciled firms. Finally, using panel regression analysis, we find that the growth in the importance of the Australian market is positively related to the growth in the size of the firm and negatively related to the size of the percentage spread in the Australian market, implying that as firms grow larger and their cost of trading in Australia declines, the Australian market becomes more informative.

Using detailed hand-collected data on firm ownership and board cultural diversity from Sweden, we find that foreign ownership is positively associated with board cultural diversity. This relationship is not an artifact of foreign owners joining the board, and it is not driven by firms with substantial foreign focus. The presence of foreign owners on nomination committees seems to be the channel through which foreign owners implement cultural diversity. The positive relationship between foreign ownership and board cultural diversity is also more pronounced in firms where owners may have more say (family firms, dual-class share firms, and firms with concentrated ownership). However, we do not find evidence that cultural diversity increases firm value or that it is correlated with other types of diversity. Our preferred interpretation is quasi-homophily.

In this paper, we examine the role of national culture in corporate takeover decisions, by arguing that managerial risk tolerance (a combination of risk aversion and risk perception), at the national level, is a cultural trait and affects the expected net synergies CEOs require. We propose a theoretical framework that links CEO risk tolerance to the expected net synergies. We empirically show that CEOs of firms located in countries with lower levels of risk tolerance, measured by Hofstede’s (1980, 2001) uncertainty avoidance score, require higher premiums on takeovers, and show that uncertainty avoidance plays a greater role in relatively large takeovers. Additional testing reveals that CEOs from high uncertainty avoiding nations engage less in cross-border/cross-industry takeovers, suggesting that uncertainty avoidance captures more the CEO’s risk perception than his/her risk aversion.

This paper examines whether the trading activity of different investor types, institutional versus retail, can affect the relation between beta and average returns. We find that the beta-return relation is strong and positive on days with high institutional trading activity, and negative and significant on low institutional trading days. Our findings are robust and not driven by recently documented effects such as macroeconomic news and leverage constraints, among others. The evidence is consistent with the hypothesis that the preferences and characteristics of various investor types, which are revealed through their trading activity, cause the slope of the Security Market Line to change.
