China has an A-share market that is open only to local investors and a B-share market that is open only to foreign investors. Contrary to what has been observed in other markets with a similar segmented structure, the China B shares trade at a discount relative to the A shares. We show that the phenomenon can still be explained by basic economic principles. Speci®cally, the existence of the H-s...

We estimate a model with countryand industry-specific shocks that extends the dummy variable model used in the portfolio diversification literature by relaxing the restriction that all stocks with exposure to a given shock have the same exposure to that shock. We find that: i) This restriction is strongly rejected by the data. ii) Many industry betas are negative, while almost all country betas...

This paper examines the international diversification benefits subject to portfolio constraints—in particular, constraints on short selling. We show that the international diversification benefits remain substantial for U.S. equity investors when they are prohibited from short selling in emerging markets. This result is robust to investment restrictions on nonnative individuals. It is also unaf...

A very debated issue in recent years is the cyber crime and its impact on market returns and reputation of firms. The issue is made particularly actual by the proliferation of information technology and internet. Information security breaches are concerned with protecting the accessibility, integrity and confidentiality of information. As a consequence, there are potential high explicit and imp...

Increased concern for the environment has increased the number of investment opportunities in mutual funds specialized in promoting responsible environmental attitudes. This paper examines the performance and risk sensitivities of US green mutual funds vis-à-vis their conventional peers. We also analyze and compare this performance relative to other Socially Responsible Investing (SRI) mutual f...

This paper presents non-parametric estimates of spectral risk measures applied to long and short positions in 5 prominent equity futures contracts. It also compares these to estimates of two popular alternative measures, the Value-at-Risk (VaR) and Expected Shortfall (ES). The spectral risk measures are conditioned on the coefficient of absolute risk aversion, and the latter two are conditioned...

Recent research has revealed a wealth of information about the microeconomics of currency markets and thus the determination of exchange rates at short horizons. This information is valuable to us as scientists since, like evidence of macroeconomic regularities, it can provide critical guidance for designing exchange-rate models. This paper presents an optimizing model of short-run exchange-rat...

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 Internation...

This paper offers the first comprehensive analysis of legal change in the protection of shareholder and creditor rights in transition economies and its impact on the propensity of firms to raise external finance. Following La Porta et al. (1998), the paper constructs an expanded set of legal indices to capture a range of potential conflicts between different stakeholders of the firm. It supplem...

This paper analyzes the efficiency of the Brazilian banking sector over the post-privatization period of 2000-2007. We employ a Bayesian stochastic frontier approach, which provides exact efficiency estimates and confidence intervals and thus, allows an accurate comparison across institutions and bank groups. The results suggest that large banks are the most cost and profit efficient, supportin...
