A Breakdown of the Valuation Effects of International Cross‐listing*

It is well known that cross‐listing domestic stocks in foreign exchanges has significant valuation effects on the listed company's shares. Using a sample of firms with dual shares, we explore the differential effects of cross‐listing on prices and we are able to separate the different sources of the benefits of cross‐listing. These sources include market segmentation, liquidity, and the bonding of controlling shareholders to lower expropriation of firm resources. Our results show that even though the market segmentation and bonding effects are both statistically significant, the economic significance of segmentation is more than double that of bonding. Furthermore, we document an economically and statistically significant increase in the liquidity of both share classes after the listing. Overall, our results explain why less and less firms are willing to list in the USA: Sarbanes Oxley has increased the cost of adopting better governance while its benefits are not substantial; and market segmentation has decreased significantly in the last years.

The Strategy of Going Public: How UK Firms Choose Their Listing Contracts

Abstract:   UK firms going public have a choice between public offers and placings. This choice has important implications in terms of who bears the risk of the issue failing and of its costs. We find that firms with higher ex ante uncertainty choose a placing contract. Highly reputable sponsors and creditor screening serve as signals of firm quality, enabling such firms to choose a public offer. Large and multinational firms usually choose a public offer whereas there is some evidence that very small issues choose a placing. Finally, the 'hotness' of the IPO market increases the probability of placings.     

The Effect of Option Listing on Bid-Ask Spreads,Price Volatility,and Trading Activity of the Underlying OTC Stocks

This paper examines the changes in spreads, price volatility, and trading activity surrounding option listing for a sample of 144 OTC stocks. For this sample, both price volatility and volume increase, but the evidence on spreads is mixed. The increase in price volatility is attributed primarily to an increase in residual return variances. Furthermore, price volatility increases even after controlling for volume, insider trading, and spreads. Although these variables do not fully explain the causes for the increase in price volatility after option listing, the results suggest that liquidity trading or volume has a stronger effect on price volatility than insider trading. This study also finds that both the number of trades and institutional holdings show substantial increases, which are supportive of the notion that listing of options on OTC stocks attracts more attention.     

Do cross-listers bond to U.S. markets? An examination of earnings quality around SOX

Sarbanes–Oxley [SOX, hereafter] was expected to improve the overall quality of financial reporting. A large amount of research has documented the influence of SOX on companies' reporting behaviors and how those behaviors have impacted the capital market as a whole (Cohen et al., 2008; Engel et al., 2007; Lobo & Zhou, 2006). While the assumption is that the far-reaching regulation impacts all U.S.-listed companies, this paper considers whether SOX has had a differential impact on the earnings quality of foreign filers that cross-list on U.S. exchanges. Despite some minor exceptions, these foreign companies are expected to meet the same reporting standards as domestic U.S. companies. Using a sample of cross-listers around the enactment of SOX, the results suggest that cross-listed companies do not strictly comply with SOX. At the same time, a size-matched sample of domestic U.S. companies shows significant improvement across the same set of earnings quality measures. This differential impact raises concerns about the ability of domestic regulations to impose compliance on foreign filers. While some may believe that cross-listed companies are bonding themselves to U.S. regulations and reporting quality, the evidence in this paper suggests that foreign companies are more interested in the reputational gains associated with a listing in the U.S.

上海国企集团整体上市后国资监管的新架构与对策研究

诞生于国资管理体制改革特定时期的国资委,在国企集团整体上市后,势必面临自身职能的重新定位、国资监管体制的调整和监管模式重构的新挑战.上海先行探索地方国家出资企业的新架构——包含两个层次的国资监管体系:第一层次是指行使国有资产统一监管职能的“国家出资企业局”;第二层次是指履行直接出资人权利的国有资本运营公司(国资投资和经营平台).国家出资企业局未来在国资体系中定位为终极出资人身份,成为国资运营且经营性的国有资产的统一监管者;国有资本运营公司定位为直接出资人,负责国有股权直接管理,成为国有经济的多元微观载体和行为主体.这一制度安排在国资法框架范围内,最大程度地保证了国资监管的连贯、规制和规范和监管半径的简化.
