Stock market liberalization and operating performance at the firm level

I use firm-specific measures of openness to foreign investors to study the impact of stock market liberalization on firm-level operating performance. In a sample of over 1,100 firms from 28 countries, firms with stocks that are open to foreign investors experience higher growth, greater investment, greater profitability, greater efficiency, and lower leverage. Strategies to address potential endogeneity suggest that the observed relation reflects, at least in part, a causal effect of openness on operating performance.     

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.     

Why Have Debt Ratios Increased for Firms in Emerging Markets?

I study trends in capital structure between 1980 and 2004 in a sample of over 11,000 firms from 34 emerging markets. The average firm's market‐value debt ratio rose by 15 percentage points over this quarter century. I study how this rise in leverage was influenced by firm‐level factors and by the availability of debt financing at the country level. The central finding is that the increase in debt ratios can largely be attributed to changes in the characteristics of emerging market firms over this period. For the average firm, the most prominent determinants of capital structure – size, profitability, asset tangibility, and growth opportunities – all shifted in the direction implying a higher optimal level of debt. At the country level, increased financial development within the country is associated with lower debt ratios, but increased financial openness to foreign markets is associated with higher debt ratios.     

Financial market development and the importance of internal cash: Evidence from international data

We examine the impact of financial market development on the extent to which firms have to rely on internal capital for making investments. Using international data from 31 countries for the 1987–1997 period, we find evidence of a negative relationship between financial market development and the importance of internal capital. The evidence is consistent across different estimation procedures, alternative measures of financial constraints and cash flow, and the use of bootstrapped standard errors. Finally, we find that the distortionary effect of negative cash flow observations reported earlier for US data extends to international data as well.     

The impact of business group affiliation on stock price informativeness: Evidence from an emerging market

This paper examines the relationship between business group affiliation and stock price informativeness in an emerging market setting. We use stock price synchronicity as a measure, and study the impact of group affiliation ‐specifically the extent of affiliation, ownership structure and existence of group bank‐ on firm specific information content. Results reveal that the amount of firm‐specific information capitalized into stock prices tends to be lower (higher) when the firm is group‐affiliated (unaffiliated), indirectly (directly) owned, and affiliated group has (does not have) a group bank. Additionally, the extent of group affiliation maintains a non‐linear relationship with synchronicity, suggesting that the perception of higher versus lower levels of group ownership differs.     

The decision to first enter the public bond market: The role of firm reputation,funding choices,and bank relationships

This paper uses survival analysis to investigate the timing of a firm’s decision to issue for the first time in the public bond market. We find that firms that are more creditworthy and have higher demand for external funds issue their first public bond earlier. We also find that issuing private bonds or taking out syndicated loans is associated with a faster entry to the public bond market. According to our results, the relationships that firms develop with investment banks in connection with their private bond issues and syndicated loans further speed up their entry to the public bond market. Finally, we find that a firm’s reputation has a “U-shaped” effect on the timing of a firm’s bond IPO. Consistent with Diamond’s reputational theory, firms that establish a track record of high creditworthiness as well as those that establish a track record of low creditworthiness enter the public bond market earlier than firms with intermediate reputation.     

The differential effects of classified boards on firm value

Classified boards actually benefit firms that have low monitoring costs and greater needs for advisory services. Previous literature has emphasized the entrenchment effect of classified boards. However, we find that this adverse impact of classified boards can be offset or even superseded by the potential benefits of board classification for firms who hope to benefit from the advisory services of their independent directors. We show that firms with greater advising needs appoint more outside directors with diverse attributes and expertise, qualifications that enhance the ability to provide useful advice to managers. Furthermore, in such firms, board classification is associated with higher performance sensitivity of forced CEO turnover and better acquisition performance. Conversely, in firms with high monitoring costs, board classification hurts managerial equity-based incentives and risk-taking incentives. These findings suggest how and through which channels classified boards engender the differential effects on firm value.     

The impact of the dimensions of social performance on firm risk

This paper examines the impact of the individual dimensions of social performance (SP) on firm risk (total and idiosyncratic) using 16,599 firm-year observations over the period 1991–2007. We find that firm risk for S&P500 members is positively affected by Employee, Diversity, and Corporate Governance concerns. On the other hand, Community (Diversity) strengths negatively (positively) affect their risk. As to non-S&P500 members, firm risk is positively affected by Employee concerns and Diversity strengths. However, firm risk of non-S&P500 members is negatively affected by Environment strengths. The direction of causation between firm risk and SP depends on the dimension examined.     

Identifying the interaction between stock market returns and trading flows of investor types: Looking into the day using daily data

This paper introduces a new method for identifying the simultaneity between returns and trading flows. The proposed method enables us to identify the intraday interaction using daily data, and provides measures of the information content of trading flows, and their instantaneous response to public information and information revealed by market prices. Applying this method to daily data on investor types from the Korea Stock Exchange, we find significant intraday bi-directional interaction between flows and returns and their latent common drivers, altering some of the results of the previous literature based on Cholesky assumptions. Thus, we obtain a number of new insights concerning the behavior of investor types.     

Form versus substance: The effect of ownership structure and corporate governance on firm value in Thailand

We examine the relation between the quality of corporate governance practices and firm value for Thai firms, which often have complex ownership structures. We develop a comprehensive measure of corporate governance and show that, in contrast to conventional measures of corporate governance, our measurement, on average, is positively associated with Tobin’s q. Furthermore, we find that q values are lower for firms that exhibit deviations between cash flow rights and voting rights. We also find that the value benefits of complying with “good” corporate governance practices are nullified in the presence of pyramidal ownership structures, raising doubts on the effectiveness of governance measures when ownership structures are not transparent. We conclude that family control of firms through pyramidal ownership structures can allow firms to seemingly comply with preferred governance practices but also use the control to their advantage.     

Daily pricing of emerging market sovereign CDS before and during the global financial crisis

In this paper, we study the determinants of daily spreads for emerging market sovereign credit default swaps (CDSs) over the period April 2002–December 2011. Using GARCH models, we find, first, that daily CDS spreads for emerging market sovereigns are more related to global and regional risk premia than to country-specific risk factors. This result is particularly evident during the second subsample (August 2007–December 2011), where neither macroeconomic variables nor country ratings significantly explain CDS spread changes. Second, measures of US bond, equity, and CDX High Yield returns, as well as emerging market credit returns, are the most dominant drivers of CDS spread changes. Finally, our analysis suggests that CDS spreads are more strongly influenced by international spillover effects during periods of market stress than during normal times.     

The economic consequences of increased disclosure: Evidence from international cross-listings

We examine market behavior around earnings announcements to understand the consequences of the increased disclosure that non-U.S. firms face when listing shares in the U.S. We find that absolute return and volume reactions to earnings announcements typically increase significantly once a company cross-lists in the U.S. Furthermore, these increases are greatest for firms from developed countries and for firms that pursue over-the-counter listings or private placements, which do not have stringent disclosure requirements. Additional tests support the hypothesis that it is changes in the individual firm's disclosure environment, rather than changes in its market liquidity, ownership, or trading venue, that explain our findings.     

MENA stock market volatility persistence: Evidence before and after the financial crisis of 2008

The global financial crisis began with a financial meltdown in the United States in early 2008 and then it had spread to the rest of the world. In this paper we test whether the MENA equity market volatility presents a different behavior before and after the financial crisis of 2008. Using long range dependence techniques we test for long memory in the returns, absolute and squared returns of the MENA equity markets. We subject the series to unit root tests that allow for structural breaks and use the Bai and Perron (1998, Econometrica, 66, 47; 2003a, J. Appl. Econometrics, 6, 72; 2003b, Econometrics J., 18, 1) to test for multiple breaks in the mean returns. The results indicate that the volatility measures represented by absolute and squared returns show evidence of long memory for the full and subsample periods, while the returns show a weak evidence of long memory. Considering the shift dates and corresponding to the 2008 financial crisis, the returns and volatility measures display less evidence of long memory in the after crisis period as opposed to the before crisis period. The change in the returns and volatility dynamics of these markets was due to financial and economic conditions that took place in the MENA region after the crisis.     

Seeking safety: The relation between CEO inside debt holdings and the riskiness of firm investment and financial policies

CEO inside debt holdings (pension benefits and deferred compensation) are generally unsecured and unfunded liabilities of the firm. Because these characteristics of inside debt expose the CEO to default risk similar to that faced by outside creditors, theory predicts that CEOs with large inside debt holdings will display lower levels of risk-seeking behavior (Jensen and Meckling, 1976). Consistent with the theoretical predictions, we find a negative association between CEO inside debt holdings and the volatility of future firm stock returns, R&D expenditures, and financial leverage, and a positive association between CEO inside debt holdings and the extent of diversification and asset liquidity. Collectively, our results provide empirical evidence suggesting that CEOs with large inside debt holdings prefer investment and financial policies that are less risky.     

The effect of board structure on firm value: A multiple identification strategies approach using Korean data

Outside directors and audit committees are widely considered to be central elements of good corporate governance. We use a 1999 Korean law as an exogenous shock to assess whether and how board structure affects firm market value. The law mandates 50% outside directors and an audit committee for large public firms, but not smaller firms. We study this shock using event study, difference-in-differences, and instrumental variable methods, within an overall regression discontinuity approach. The legal shock produces economically large share price increases for large firms, relative to mid-sized firms; their share prices jump in 1999 when the reforms are announced.     

The dynamics of price discovery for cross-listed shares: Evidence from Australia and New Zealand

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.     

Overreaction of country ETFs to US market returns: Intraday vs. daily horizons and the role of synchronized trading

In this paper we study the intraday price formation process of country Exchange Traded Funds (ETFs). We identify specific parts of the US trading day during which Net Asset Values (NAVs), currency rates, premiums and discounts, and the S&P 500 index have special effects on ETF prices, and characterize a special intraday and overnight updating structure between these variables and country ETF prices. Our findings suggest a structural difference between synchronized and non-synchronized trading hours. While during synchronized trading hours ETF prices are mostly driven by their NAV returns, during non-synchronized trading hours the S&P 500 index has a dominant effect. This effect also exceeds the one that the S&P 500 index has on the underlying foreign indices and suggests an overreaction to US market returns when foreign markets are closed.     

The colors of investors’ money: The role of institutional investors around the world

We study the role of institutional investors around the world using a comprehensive data set of equity holdings from 27 countries. We find that all institutional investors have a strong preference for the stock of large firms and firms with good governance, while foreign institutions tend to overweight firms that are cross-listed in the U.S. and members of the Morgan Stanley Capital International World Index. Firms with higher ownership by foreign and independent institutions have higher firm valuations, better operating performance, and lower capital expenditures. Our results indicate that foreign and independent institutions, with potentially fewer business ties to firms, are involved in monitoring corporations worldwide.     

The impact of capital market imperfections on investment–cash flow sensitivity

We examine the investment–cash flow sensitivity of US manufacturing firms in relation to five factors associated with capital market imperfections – fund flows, institutional ownership, analyst following, bond ratings, and an index of antitakeover amendments. We find a steady decline in the estimated sensitivity over time. Furthermore, we find that investment–cash flow sensitivity decreases with increasing fund flows, institutional ownership, analyst following, antitakeover amendments and with the existence of a bond rating. The overall evidence suggests that investment–cash flow sensitivity decreases with factors that reduce capital market imperfections.     

The choice of ADRs

We study the determinants of a firm’s decision to issue one of the four available ADR programs (Level I, Level II, Level III, and Rule 144A). We find that the firm’s attributes (size, income, asset growth, leverage, privatization, ownership structure, and country-of-origin) and the firm’s home-country institutional variables (accounting rating and legal protection of minority shareholders) condition this choice. We also examine the issuing activity and the determinants of the ADR choice before and after the enactment of the Sarbanes–Oxley (SOX) Act. Following this structural change, we provide evidence of a reallocation between ADR programs. Compared to the pre-SOX period, firms from emerging markets, and those from countries with weak legal protection of minority shareholders, are more likely after SOX to choose Rule 144A and Level III, respectively.
