This paper examines continuous-time models for the S&P 100 index and its constituents. We find that the jump process of the typical stock looks significantly different than that of the index. Most importantly, the average size of a jumps in the returns of the typical stock is positive, while it...

We develop an Artificial Stock Market - an agent-based simulation model of the stock market with many risky assets. The ASM has three layers of heterogeneous and interacting agents, and generates prices for 150 stocks. We present the current state of the model and demonstrate its ability to...

This paper presents an equilibrium model that provides a rational explanation for two features of data that have been considered puzzling: The positive relation between US dividend yields and nominal interest rates, often called the Fed-model, and the time-varying correlation of US stock and...

We estimate the relative signal jump variance (RSJV) as the difference between the realized positive half-variance and negative half-variance divided by the realized variance using high-frequency intraday data and investigate its role in the cross-sectional pricing in the Chinese stock market....

We investigate a general multiple security equilibrium model in which firms adjust their capital stock in response to economic shocks. Asset values are determined by competitive risk-averse investors. When corporate capital increases in value, firms react by creating more of it. This leads to...

We document the predictive ability and economic significance of global economic policy uncertainty for U.S. equity returns. After orthogonalizing global economic policy uncertainty (global EPU) with respect to the U.S. EPU, we find that it has significant predictive power for aggregate stock...

This article investigates returns and volatility linkages among stock markets, including emerging Asian (e.g., India, China, Bangladesh, Malaysia, Philippine, and South Korea) stock markets and developed (e.g., United States, United Kingdom, Japan, and Singapore) stock markets. During the sample...

A large literature uses high-frequency changes in interest rates around FOMC announcements to study monetary policy. These yield changes have puzzlingly low explanatory power for the stock market - even in a narrow 30-minute window. We propose a new approach to test whether the unexplained...

This paper investigates how the stock market reacts to firm level liquidity shocks. We find that negative and persistent liquidity shocks not only lead to lower contemporaneous returns, but also predict negative returns for up to six months in the future. Long-short portfolios sorted on past...

This paper investigates the relationship between liquidity and stock returns in the Vietnam stock market during financial crisis using a data set ranging from 2006 to 2010. Employing a rich and detailed dataset of characteristics of firm listed in Ho Chi Minh City Stock Exchange, the results...
