Art as an Investment and the Underperformance of Masterpieces

American Economic Review 2002 92(5), 1656-1668
This paper constructs a new data set of repeated sales of artworks and estimates an annual index of art prices for the period 1875-2000. Contrary to earlier studies, we find art outperforms fixed income securities as an investment, though it significantly under-performs stocks in the US. Art is also found to have lower volatility and lower correlation with other assets, making it more attractive for portfolio diversification than discovered in earlier research. There is strong evidence of underperformance of masterpieces, meaning expensive paintings tend to underperform the art market index. The evidence is mixed on whether the law of one price holds in the New York auction market.

Vested Interest and Biased Price Estimates: Evidence from an Auction Market

Journal of Finance 2005 60(5), 2409-2435
ABSTRACT This study employs a new data set from art auctions to examine the relationship between auctioneer presale price estimates and the long‐term performance of artworks. We find that the price estimates for expensive paintings have a consistent upward bias over a long period of 30 years. High estimates at the time of purchase are associated with adverse subsequent abnormal returns. Moreover, the estimation error for individual paintings tends to persist over time. These results are consistent with the view that auction house price estimates are affected by agency problems and that some investors are credulous.

Measuring International Economic Linkages with Stock Market Data

Journal of Finance 1996 51(5), 1743-1763 open access
ABSTRACT This article develops a new framework for measuring financial and real economic linkages between countries. Using United States and United Kingdom data from 1957 to 1989, we find closer financial linkages after the Bretton Woods currency arrangement was abandoned and Britain suspended exchange controls. In a pairwise application to fifteen countries over a shorter period, we also find that news about future dividend growth is more highly correlated between countries than contemporaneous output measures. This suggests that there are lags in the international transmission of economic shocks and that contemporaneous output correlation may understate the magnitude of integration.

Turning over Turnover

Review of Financial Studies 2007 20(6), 1749-1782 open access
This article applies the methodology of Bai and Ng (2002, 2004) for decomposing panel data into systematic and idiosyncratic components to both stock returns and turnover panels. This approach works well for both returns and turnover, despite the presence of severe heteroscedasticity and nonstationarity of individual stocks' turnover. We test the mutual fund separation model of Lo and Wang (2000). Trading due to systematic risk in returns can account for 66% of systematic turnover. Thus, portfolio rebalancing due to systematic risk is a very important motive for stock trading. Finally, several common turnover measures may understate the impact of stock trading.

Credit spreads in the market for highly leveraged transaction loans

Journal of Banking & Finance 1998 22(10-11), 1249-1282 open access
This paper is an empirical exploration of the determinants of the required credit spreads on highly leveraged transaction (HLT) loans. The analysis uses a multi-factor spread model to estimate the movement of loan spreads relative to spreads required in the (competing) corporate bond market as well as the significance of loan-specific characteristics in determining loan spreads. The empirical estimates are based on the Loan Pricing Corporation's database which consists of over 4000 loan transactions between 1987 and 1994. We find a positive HLT loan spread sensitivity to changes in spreads in the corporate bond market, but this sensitivity is significantly less than unity; indicating that the HLT loan market and high yield public debt market are not fully integrated. Furthermore, there is evidence that lenders augment, rather than substitute, loan yield spreads with additional fees for syndication, commitment and cancellation risks. In general syndicated loans have lower yield spreads than other HLT loan types.

Large Investors, Price Manipulation, and Limits to Arbitrage: An Anatomy of Market Corners

Review of Finance 2006 10(4), 645-693 open access
Corners were prevalent in the nineteenth and early twentieth century. We first develop a rational expectations model of corners and show that they can arise as the result of rational behavior. Then, using a novel hand-collected data set, we investigate price and trading behavior around several well-known stock market and commodity corners which occurred between 1863 and 1980. We find strong evidence that large investors and corporate insiders possess market power that allows them to manipulate prices. Manipulation leading to a market corner tends to increase market volatility and has an adverse price impact on other assets. We also find that the presence of large investors makes it risky for would-be short sellers to trade against the mispricing. Therefore, regulators and exchanges need to be concerned about ensuring that corners do not take place since they are accompanied by severe price distortions.

Return generating process and the determinants of term premiums

Journal of Banking & Finance 1996 20(7), 1251-1269 open access
This paper examines asset pricing theories for treasury bonds using longer maturities than previous studies and employing a simple multi-factor model. We allow bond factor loadings to vary over time according to term structure variables. The model examines not only the time variation in the expected returns of bonds but also their unexpected returns. This allows us to explicitly test some asset pricing restrictions which are difficult to study under existing frameworks. We confirm that the pure expectation theory of the term structure of interest rates is rejected by the data. Our empirical study of a two-factor model finds substantial evidence of time-varying term-premiums and factor loadings. The fact that factor loadings vary with long-term interest rates and yield spreads suggest that bond return volatilities are sensitive to interest rate levels.
