This paper applies the methodology of Bai and Ng (2002, 2004) for decomposing large panel data into systematic and idiosyncratic components to both returns and turnover. Combining the methodology with a generalized-least-squares-based principal components procedure, we demonstrate that this...

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...

This paper introduces a recently developed consistent statistic by Bai and Ng (2002) to determine the number of factors in an approximate multifactor model. We use this new approach to study a recent work by Lo and Wang (2000), which shows that a multifactor asset-pricing model not only imposes...

The methodology of Bai and Ng (2002, 2003) for decomposing large panel data into systematic and idiosyncratic components is applied to both returns and turnover. Combining this with a GLS-based principal components approach, we demonstrate that their procedure works well for both returns and...

type="main" <title type="main">ABSTRACT</title> <p>We examine the pricing of both aggregate jump and volatility risk in the cross-section of stock returns by constructing investable option trading strategies that load on one factor but are orthogonal to the other. Both aggregate jump and volatility risk help explain...</p>

type="main" <title type="main">ABSTRACT</title> <p>This paper introduces a new hand-collected data set that tracks restrictions on shareholder rights at approximately 1,000 firms from 1978 to 1989. In conjunction with the 1990 to 2006 IRRC data, we track shareholder rights over 30 years. Most governance changes occurred...</p>

Prices of equity index put options contain information on the price of systematic downward jump risk. We use a structural jump-diffusion firm value model to assess the level of credit spreads that is generated by option-implied jump risk premia. In our compound option pricing model, an equity...

We investigate the relationship between CEO centrality -- the relative importance of the CEO within the top executive team in terms of ability, contribution, or power -- and the value and behavior of public firms. Our proxy for CEO centrality is the fraction of the top-five compensation captured...
