Competition and cooperation among exchanges: A theory of cross-listing and endogenous listing standards

We analyze firms’ choice of exchange to list equity and exchanges’ choice of listing standards when insiders have private information about firm value, but outsiders can produce (noisy) information at a cost. Exchanges are populated by two kinds of investors, whose numbers vary across exchanges: sophisticated (low information production cost) investors and ordinary (high–cost) investors. While firms are short-lived, exchanges are long-lived, value-maximizing agents whose listing and disclosure standards evolve over time. The listing standards chosen by exchanges affect their “reputation,” since outsiders can partially infer the rigor of these standards from the post-listing performance of firms. We show that, while exchanges use their listing standards as a tool in competing for listings with other exchanges, this will not necessarily lead to a “race to the bottom” in listing standards. Further, a merger between two exchanges may result in a higher listing standard for the combined exchange relative to that of either of the merging exchanges. We develop several other implications for firms’ listing choices and resulting valuation effects, the impact of competition and co-operation among exchanges on listing standards, and the optimal regulation of exchanges.     

Financial market integration and the value of global diversification: Evidence for US acquirers in cross-border mergers and acquisitions

In contrast to the previously documented cross-border discount, we find that there is positive cross-border effect for US acquirers during late 1990s and early 2000s. This is especially particular the case for those that acquire/merge with targets from segmented financial markets where acquirers experience significantly higher positive abnormal returns than those that acquire targets from integrated financial markets. Furthermore, firms acquiring segmented-market targets are also characterized by significantly higher post-merger operating performance improvement. The results indicate that the observed positive cross-border effect is mainly due to the increase in the number of transactions involving targets from segmented markets, in which the average firm experience significant financial constraints. We contend that value is created by a combination of firms with different financial market integration status, in which funds are provided to high cost firms. The finding that the value creation is even higher within the group of acquirers with a lower cost of capital provides additional support for our conjecture.     

The value of excess cash and corporate governance: Evidence from US cross-listings

We examine whether and how a US cross-listing mitigates the risk that insiders will turn their firm’s cash holdings into private benefits. We find strong evidence that the value investors attach to excess cash reserves is substantially larger for foreign firms listed on US exchanges and over-the-counter than for their domestic peers. Further, we show that this excess-cash premium stems not only from the strength of US legal rules and disclosure requirements, but also from the greater informal monitoring pressure that accompanies a US listing. Overall, because investors’ valuation of excess cash mirrors how they expect the cash to be used, our analysis shows that a US listing constrains insiders’ inefficient allocation of corporate cash reserves significantly.     

Investigating sources of unanticipated exposure in industry stock returns

This paper investigates the sources of both foreign exchange rate and interest rate exposure of industry level portfolios in the G7, decomposing exposure into cash flow and discount rate effects. Initial examination of the degree of exposure on industry returns produces results consistent with the prior literature: that there is little evidence of exchange rate exposure in most industries - the exchange rate exposure puzzle. However, rather than relying solely on the sensitivity of industry returns, we examine the cash flow sensitivity to foreign exchange exposure, of primary interest to firm managers. Critically, decomposing the exposure into cash flow and discount rate components unlocks the exact extent and nature of exposure. Our results show industries have significant cash flow and discount rate exposures. These exposures increase with the level of trade openness and the spread between permanent cash flow exposure and transitory discount rate exposure widens.     

Risk contagion among international stock markets

We develop a stochastic volatility model with jumps in returns and volatility to analyze the risk spillover from the U.S. market and the regional market to a number of European countries’ equity markets. The key advantage of this approach compared to the earlier approaches is that it enables us to identify jumps and investigate spillover of extreme events across borders. We find that a large part of the jumps in the local markets are due to the U.S. market and the regional market. The U.S. contribution to the variances is in general below the contribution from the regional market. In general, we observe an increasing integration during the last two decades, which, to some extent, can be related to the advancement of the European Union. Furthermore, we show that the identification of the jumps can be used as a useful signal for portfolio reallocation.     

Prestigious stock exchanges: A network analysis of international financial centers

In this paper, we use methods from social network analysis to assess the relative importance of financial centers around the world. Using data from virtually the entire universe of global equity activity, we present complete rankings for 45 separate locations for the period 1990–2006. Our analysis constructs a network measure of prestige based on their ability to attract global IPOs. U.S. exchanges are effectively the unique hosts for cross-border equity activity from many other locations. Moreover, they are the destination of choice for most companies coming from locations with highly prestigious exchanges. We also document the emergence of several competing stock exchanges from developed and emerging market economies. The ascent of these stock markets, however, might reflect improved conditions in a growing global market rather than a decline in the competitiveness of U.S. exchanges.     

Volume and skewness in international equity markets

We examine the relation between trading volume and skewness in 11 international stock markets using daily and monthly data from January 1980 to August 2004. We construct single equation and VAR models of the relation between the first three moments of market returns and trading volumes. Our results show hitherto unrecognised channels of influence, and support the investor heterogeneity approach to explaining return asymmetries.     

The contribution of stock repurchases to the value of the firm and cash holdings around the world

Using corporate payout data from 33 economies, this study investigates the contribution of stock repurchases to the value of the firm and cash holdings in different country-level investor protection environments. We find that stock repurchases contribute more to firm value in countries with strong investor protection than in countries with weak investor protection. We also report that dividends contribute approximately 60% more to firm value than repurchases in countries with weak investor protection. Furthermore, as the proportion of repurchases in total payouts increases, the marginal value of cash increases in countries with strong investor protection, whereas it declines in countries with weak investor protection. In a poor investor protection environment, the marginal value of cash for a firm that makes 100% of its payouts via repurchases is 12 cents lower than that for a firm that distributes 100% of its payouts via dividends. Overall, our findings highlight that stock repurchases are less effective than dividends in mitigating agency problems associated with free cash flow in countries with poor investor protection.     

Overnight information and stochastic volatility: A study of European and US stock exchanges

This paper provides a comprehensive evaluation of the predictive ability of information accumulated during nontrading hours for a set of European and US stock indexes. We introduce a stochastic volatility model, which conditions on lagged overnight information, distinguishes between the nontrading periods of weeknights, weekends, holidays and long weekends, and allows for an asymmetric leverage effect on the impact of overnight news. We implement Bayesian methods for estimation and ranking of the empirical models, and find two key results: (i) there is substantial predictive ability in financial information accumulated during nontrading hours; and (ii) the performance of stochastic volatility models improves considerably by separating the asymmetric impact of positive and negative news made available over weeknights, weekends, holidays and long weekends.     

Foreign exchange risk pricing and equity market segmentation in Africa

This work is the first to investigate simultaneously the occurrence of unconditional currency risk pricing and equity market segmentation in Africa’s major stock markets. The multi-factor asset pricing theory provides the theoretical framework for our model. We find strong evidence suggesting that Africa’s equity markets are partially segmented. However, we find insufficient evidence to reject the hypothesis that foreign exchange risk is not unconditionally priced in Africa’s stock markets. This result is robust to alternative foreign exchange rate-adjusted return measures. These findings suggest that international investors can diversify into Africa’s equity markets without worrying about unconditional risks associated with foreign exchange rate fluctuations.

Motivations for public equity offers: An international perspective

This paper examines the motivations for public equity offers, using a sample of 17,226 initial public offerings and 13,142 seasoned equity offerings from 38 countries between 1990 and 2003. We estimate the uses of funds raised in both initial and seasoned offerings. Firms appear to spend incremental dollars on both R&D and capital expenditures, consistent with the investment financing explanation of equity issues. However, consistent with the mispricing explanation, high market to book firms tend to save more cash and offer a higher fraction of secondary shares in SEOs than low market to book firms.     

Volatility clustering,leverage effects,and jump dynamics in the US and emerging Asian equity markets

This paper proposes asymmetric GARCH-Jump models that synthesize autoregressive jump intensities and volatility feedback in the jump component. Our results indicate that these models provide a better fit for the dynamics of the equity returns in the US and emerging Asian markets, irrespective whether the volatility feedback is generated through a common GARCH multiplier or a separate measure of volatility in the jump intensity function. We also find that they can capture several distinguishing features of the return dynamics in emerging markets, such as, more volatility persistence, less leverage effects, fatter tails, and greater contribution and variability of the jump component.     

Realizing the volatility impacts of sovereign credit ratings information on equity and currency markets: Evidence from the Asian Financial Crisis

We examine the effects of different types of sovereign rating announcements on realized stock and currency market volatilities and cross-asset correlations around periods of financial crises. Using intraday market data and sovereign ratings data for nine sample countries in the Asia-Pacific region over 1997–2001, we find that currency and stock markets react somewhat heterogeneously to various rating announcements and that stock markets are more responsive to rating news than currency markets. We find new evidence that ratings events have significant and asymmetric impacts on intraday market data and that national market attributes influence rating impacts during financial crises.     

Deciphering the Motives for Equity Carve-Outs

I analyze 181 equity carve‐outs to determine whether the transactions are motivated by potential efficiency improvements or by an opportunity to sell overvalued equity. Carve‐out operating performance peaks at issue, declining significantly thereafter. Parents sell a greater percentage of shares when subsequent performance is poor. A negative relation also exists between long‐term excess returns and the percentage of shares sold. If subsequent performance is correlated with the degree to which parent managers believe carve‐out subsidiaries are over‐ or undervalued, results imply that many carve‐outs are conducted, not to improve efficiency, but to sell potentially overvalued equity.     

Great expectations: Banks as equity underwriters

We examine the in-roads commercial banks have made into equity underwriting over 1990–2002. While banks end the period handling upwards of 25% of equity underwriting, this increase results almost exclusively from acquisitions of investment banks with an already established market share of equity underwriting. We find a significant decline in the market share of equity underwriting that banks acquired in the post-merger period, a decline that is larger than that experienced by independent investment banks of comparable reputation. Banks lose market share because they originate fewer IPOs and their IPOs have a lower incidence of follow-on SEOs compared to independent investment banks. Following the merger, banks experience a large fall off in their ability to retain follow-on SEOs and are less successful in winning SEO mandates when an issuer switches from its IPO underwriter. Overall, the findings suggest it has been difficult for banks to achieve scope economies in equity underwriting.     

Country-specific equity market characteristics and foreign equity portfolio allocation

Do country-specific equity market characteristics explain variations in foreign equity portfolio allocation? We study this question using comprehensive foreign equity portfolio holdings data and different measures of country-specific equity market factors for 36 host countries. Employing panel data econometric estimations, our investigation shows that foreign investors prefer to invest more in larger and highly visible developed markets which are more liquid, exhibit a higher degree of market efficiency and have lower trading costs. The findings imply that by improving the preconditions necessary for well-functioning capital markets, policymakers should be able to attract higher levels of foreign equity portfolio investments.     

Shareholder governance, bondholder governance, and managerial risk-taking

We examine the relation between the overall corporate governance structure and managerial risk-taking behavior. We find that the overall governance structure has a significant impact on how managers make decisions on investment policy: strong bondholder governance motivates more low-risk investments such as capital expenditure and lower high-risk investments such as R&D expenditures, whereas weak shareholder governance (entrenched managers) leads to more R&D expenditures. Moreover, we find that the effects of governance on investment policy differ significantly between speculative and investment-grade firms. For speculative firms, strong bondholder or shareholder governance leads to more capital expenditures and low R&D investments. For investment-grade firms, strong bondholder or shareholder governance leads to low capital expenditures and an insignificant impact on R&D investments. Furthermore, financing and investment covenants exhibit strong binding power to deter risky investments. Finally, a more dependent (or a less independent) board is associated with low capital expenditures and high R&D investments.     

Changes in cash holdings around the S&P 500 additions

We analyze the changes in cash holding policies of S&P 500 firms from before to after their inclusion in the index. One year after inclusion, their mean industry-adjusted cash holdings decline by nearly 32% from the year before inclusion. Several factors explain this decline. The precautionary motive for cash subsides due to these firms becoming more visible, less uncertain, and less constrained to raise cheap external capital. Corporate governance deteriorates after inclusion due to increased managerial entrenchment, which leads to a reduction in cash as suggested by the free cash flow hypothesis. Most index firms face diminishing investment opportunities and decreasing capital expenditures, which implies a lesser need for cash holdings related to the transaction motive.     

The impact of geographic diversification on firm performance

This paper empirically examines the economic effects of both corporate industrial and geographic diversifications. Using a sample of 28,050 firm-year observations from 1990 to 1998, we find that industrial and geographic diversifications are associated with firm value decrease. Consistent with Denis et al. [Denis, D. J., Denis, D. K., and Yost, K. (2002). Global diversification, industrial diversification, and firm value. Journal of Finance, 57, 1951-1979], the costs of corporate diversification may outweigh the benefits of diversification. We find that geographically diversified firms have higher R&D expenditures, advertising expenses, operating income, ROE and ROA than industrially diversified firms. In addition, higher R&D expenditures create value for multi-segment global firms, but not for single-segment global firms. This result implies that there exists an interaction effect between industrial and geographic diversification. We also examine the effects of agency cost issues, as characterized by the diversification discount, on both industrial and geographic diversification. Consistent with the agency explanation, firms with high equity-based compensation are associated with higher firm value than firms with low equity-based compensation. Also, we find that firms with a higher insider ownership percentage are associated with higher excess value.
