Private information in currency markets

Using daily abnormal currency returns for the universe of countries with flexible exchange rates, we show local currency depreciations ahead of unscheduled, public sovereign debt downgrade announcements. Consistent with the private information hypothesis, the effect is stronger in lower institutional quality countries and holds after we control for concurrent public information and for publicly available rumors about the forthcoming downgrades. Our results persist when abnormal currency returns are adjusted for global carry and dollar risk factors, world equity and bond returns, as well as local stock market returns. Finally, the currency depreciations are permanent, providing evidence for a link between fundamentals and currency markets.     

Disclosure and the Cost of Capital: Evidence from the Market's Reaction to Firm Voluntary Adoption of IAS

Abstract:  Using a unique international setting where the effects of disclosure on firm value can be measured in a constant regulatory environment and in isolation of other confounding factors, this paper shows that firms can increase their value through their choice of accounting standards. Specifically, we document strong positive abnormal returns at the announcement of voluntary adoption of International Accounting Standards (IAS / IFRS) by a sample of international firms and an economically significant reduction in long-run returns, consistent with a reduction in the cost of capital. Consistent with these results we also document evidence of an upgrade in analyst recommendations after the IAS / IFRS adoption announcement and a reduction in the implied cost of capital. Finally, we find strong evidence that the documented abnormal returns are consistent with signaling and bonding benefits stemming from the reduction in asymmetric information. Our results highlight the importance of increased disclosure on minority shareholder protection and on corporate governance in general.     

The value of information in cross-listing

Until 2004, the London Stock Exchange allowed firms to be traded in the specialized SEAQ-I platform without the firm's involvement. Trading only required an application by one LSE trading member firm. Such an institutional arrangement, which made cross-listings possible without a firms' approval, allows for a direct test of different theories of foreign listing. In particular, we can differentiate between market segmentation and liquidity hypotheses, which rely on a firm trading in a foreign exchange and informational hypotheses, which assume that a firm makes the decision to trade in a foreign exchange. We identify a sample of international firms that are admitted to trading on London's SEAQ-I platform without their involvement. We estimate the valuation effects of this multi-market trading event and compare them to those enjoyed by firms that pursue a standard London Stock Exchange cross-listing. A cross-sectional abnormal returns analysis documents significant evidence in support of information-related hypotheses of cross-listing. An analysis of the firms' home market price volatility corroborates the results.     

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.
