This paper documents that speed is crucially important for high-frequency trading strategies based on U.S. macroeconomic news releases. Using order-level data on the highly liquid S&P 500 ETF traded on NASDAQ from January 6, 2009 to December 12, 2011, we find that a delay of 300 ms or more significantly reduces returns of news-based trading strategies. This reduction is greater for high impact news and on days with high volatility. In addition, we assess the effect of algorithmic trading on market quality around macroeconomic news. In the minute following a macroeconomic news arrival, algorithmic activity increases trading volume and depth at the best quotes, but also increases volatility and leads to a drop in overall depth. Quoted half-spreads decrease (increase) when we measure algorithmic trading over the full (top of the) order book.

This paper examines the foreign bias in international asset allocation. Following extant literature in behavioral finance, we argue that a society’s culture and the cultural distance between two markets play an important role in explaining the foreign bias. In particular, we hypothesize that the degree of a nation’s uncertainty avoidance affects the foreign bias (more uncertainty-avoiding countries allocate less to foreign markets), as does the degree of a country’s individualism (in individualistic countries performance is more directly attributed to a person and less to teams, causing these individuals to be more aggressive in their foreign asset allocations). We further expect that the degree of cultural distance between two countries affects the amount of money allocated to that market. Based on extensive robustness analyses, we find support for our hypotheses on the role of culture in international asset allocation.

We examine the impact of cultural diversity in boards of directors on firm performance. We construct a measure of national cultural diversity by calculating the average of cultural distances between board members using Hofstede's culture framework. Our findings indicate that national cultural diversity in boards negatively affects firm performance measured by Tobin's Q and ROA. These results hold after controlling for potential endogeneity using firm fixed effects and instrumental variables regressions. Further, the results are robust to controlling for a wide range of board and firm characteristics, including various measures of “foreignness” of the firm, alternative culture frameworks, and other measures of culture. The negative impact of cultural diversity on performance is mitigated by the complexity of the firm and the size of foreign sales and operations. In addition, we find that the negative effects of cultural diversity are concentrated among the independent directors. Finally, we find that not all aspects of cultural differences are equally important and that it is mainly the diversity in individualism and masculinity that affects the effectiveness of boards of directors.

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.

This paper examines the style-based feedback trading behavior of U.S. mutual fund managers. We provide an empirical version of Barberis and Shleifer’s style-switching model. We find style-based feedback trading for 77% of the funds, half of which is positive (negative) feedback trading. There is evidence for “twin style” switching, where capital is channeled between value and growth, and between large- and small-cap. Growth (value) funds apply more positive (negative) feedback trading. Funds that switch more aggressively are younger and have higher expense ratios. Finally, we find that positive (negative) feedback trading yields positive (negative) alpha.

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.
