The impacts of large trades by trader types on intraday futures prices: Evidence from the Taiwan Futures Exchange

We find that China's P/E ratio is comparable to that of the U.S. S&P 1500 index, a broad based index covering large, middle, and small capitalization firms. We provide an explanation as to why China's seemingly low P/E ratio is not surprising in light of the economic growth that it has experienced. Specifically, we show that (i) the P/E ratio is negatively associated with earnings volatility in both the Chinese and U.S. stock markets with an economically significant magnitude; and (ii) historical earnings volatility is considerably higher in China than in the U.S. Higher earnings volatility in China offsets higher growth prospect in setting the P/E ratio, making its P/E ratio much closer to what is observed empirically than otherwise implied by its growth rate.     

Exchange risk and universal returns: A test of international arbitrage pricing theory

According to the international arbitrage pricing theory (IAPT) posited by Solnik (1983), currency movements affect assets' factor loadings and associated risk premiums. Based on a novel universal return decomposition, we propose an empirical model to test this proposition and perform tests using U.S. stock returns in the period 1975–2008. Our results confirm that currency movements significantly affect the market betas of a large proportion of stocks. Further cross-sectional tests indicate that currency movements affecting the market factor are significantly priced in stock returns. Based on these and other findings, we conclude that Solnik's IAPT is supported. An important implication of our findings is that exchange rate risk can broadly affect stock returns through both factor loading and residual factor channels.

A historical overview of financial crises in the United States

One of the few constants since the United States declared its independence is the presence of frequent financial crises with similar causes. In the nineteenth century, these panics were frequent with eight occurring over the century. However, following the Second World War there was a period of relative calm, which may have led to complacency. The Savings and Loans and the current financial crises have shown that these events remain a very real threat to economic stability.     

The financial crisis: What is there to learn?

Many are currently studying the origins of the financial crisis in an attempt to answer two seemingly simple questions: why did it happen, and can another crisis be prevented? Those two questions have proved incredibly divisive. The majority opinion of The United States Financial Crisis Inquiry Commission was submitted with two dissenting positions. Furthermore, The 2010 Economic Report of the United States President does not perfectly align with any opinion presented in that report. Few studies, however, provide proper consideration to the evolution of macroeconomic thought and lengthening of the business cycle preceding the current crisis.     

Is ethical money financially smart? Nonfinancial attributes and money flows of socially responsible investment funds

We study the money flows into and out of socially responsible investment (SRI) funds around the world. In their investment decisions, investors in SRI funds may be more concerned with ethical or social issues than with fund performance. Therefore, SRI money flows are less related to past fund returns. Ethical money is less sensitive to past negative returns than are conventional fund flows, especially when SRI funds primarily use negative or Sin/Ethical screens. Social attributes of SRI funds weaken the relation between money inflows and past positive returns. However, money flows into funds with environmental screens are more sensitive to past positive returns than are conventional fund flows. Stock picking based on in-house SRI research increases the money flows. These results give evidence on the role of nonfinancial attributes, which induce heterogeneity of investor clienteles within SRI funds. We find no evidence of a smart money effect, as the funds that receive more inflows neither outperform nor underperform their benchmarks or conventional funds.     

Serial CEO incentives and the structure of managerial contracts

I explore CEOs’ incentives to select firm strategies and to acquire firm-specific skills when CEOs have job-hopping opportunities. Several features of managerial compensation, such as benchmarking of pay to larger and more prestigious companies, payments unrelated to past performance, unrestricted stock awards for highly paid CEOs, long-term incentives, and higher pay in companies granting long-term incentives, emerge in the optimal contract. I argue that the model can explain the change in the structure and the surge in US CEO compensation as well as differences across countries and across firms within a country.     

A computing bias in estimating the probability of informed trading

This study identifies a factor that leads to a bias in estimating the probability of informed trading (PIN), a widely-used microstructure measure. It is shown that, along with the numerical maximization of the likelihood function for PIN, the floating-point exception (i.e., overflow or underflow) may eliminate feasible solutions to the actual parameters in the optimization problem. Approximately 44% of PIN estimates for recent stock market data may have been subject to a downward bias that is more pronounced for active stocks than for inactive stocks. This study develops a remedy to mitigate the resulting bias.     

Automation, speed, and stock market quality: The NYSE's Hybrid

Automation and trading speed are increasingly important aspects of competition among financial markets. Yet we know little about how changing a market's automation and speed affects the cost of immediacy and price discovery, two key dimensions of market quality. At the end of 2006 the New York Stock Exchange introduced its Hybrid Market, increasing automation and reducing the execution time for market orders from 10 seconds to less than one second. We find that the change raises the cost of immediacy (bid-ask spreads) because of increased adverse selection and reduces the noise in prices, making prices more efficient.     

Basel Core Principles and bank soundness: Does compliance matter?

This paper studies whether compliance with the Basel Core Principles for effective banking supervision (BCPs) is associated with bank soundness. Using data for over 3000 banks in 86 countries, we find that neither the overall index of BCP compliance nor its individual components are robustly associated with bank risk measured by individual bank Z-scores. We also fail to find a relationship between BCP compliance and systemic risk measured by a system-wide Z-score.
