This paper proposes a new approach to exploit the information in high frequency data for the statistical inference of continuous-time affine jump diffusion (AJD) models with latent variables. For this purpose, we construct unbiased estimators of the latent variables and their power functions...

In this paper, we propose a nonparametric estimator of the short rate diffusion process using observations of a panel of yields. The proposed estimator can greatly reduce the bias of the nonparametric estimator proposed in Stanton (1997) that uses a single time series of short rate observations....

In this paper, we propose a unifying affine-quadratic jump-diffusion framework for the term structure dynamics. The model incorporates both stochastic volatility and random jumps in the short rate process. In particular, we extend the existing models by explicitly modeling the jump intensity as...

Recently, the Chicago Board Options Exchange (CBOE) redesigned its widely followed stock market volatility index (VIX). Instead of tracking the Black-Scholes implied volatility of at-the-money options, it is now based on the theoretically superior model-free implied volatility. In this paper, we...

This paper specifies a multivariate stochastic volatility (SV) model for the Samp;P500 index and spot interest rate processes. We first estimate the multivariate SV model via the efficient method of moments (EMM) technique based on observations of underlying state variables, and then investigate...

In this paper, we propose a unifying class of affine-quadratic term structure models (AQTSMs) in the general jump-diffusion framework. Extending existing term structure models, the AQTSMs incorporate random jumps of stochastic intensity in the short rate process. Using information from the...

This paper uses adverse selection in corporate information disclosure to explain a recently documented asset pricing anomaly. Ang, Hodrick, Xing, and Zhang (2006a) show that stocks with high idiosyncratic return volatilities tend to have low future returns. In this paper, we find that...

Utilizing a novel style identification procedure, we show that style-shifting is a dynamic strategy commonly employed by hedge fund managers. Three quarters of hedge funds shifted their investment styles at least once over the period from January 1994 to December 2013. We perform empirical tests...

Earnings announcements present a clear risk to investors and, under rational asset pricing theory, such risk should be consistently priced in stocks. However, we find that stocks with high earnings announcement risk earn significantly higher returns only during months when firms have earnings or...
