This paper presents a dynamic equilibrium model of bond markets, in which two groups of agents hold heterogeneous expectations about future economic conditions. Our model shows that heterogeneous expectations can not only lead to speculative trading, but can also help resolve several challenges...

Does information asymmetry affect the cross-section of expected stock returns? Using institutional ownership data from the Shanghai Stock Exchange, we show that institutions have a strong information advantage over individual investors. We then show that the aggressiveness of institutional...

Using holdings data on a representative sample of all Shanghai Stock Exchange investors, we show that increases in ownership breadth (the fraction of market participants who own a stock) predict low returns: highest change quintile stocks underperform lowest quintile stocks by 23% per year....

We analyze whether mid-level managers in securitized finance were aware of the housing bubble and a looming crisis in 2004-2006 using their personal home transaction data. To the extent that the practice of securitization may have led to lax screening of subprime borrowers, we find that the...

Futures positions of commercial hedgers in wheat, corn, soybeans and cotton fluctuate much more than expected output. Hedgers' short positions are positively correlated with price changes. Together, these observations raise doubt about the common practice of categorically classifying trading by...

We construct housing price indices for 120 major cities in China in 2003-2013 based on sequential sales of new homes within the same housing developments. By using these indices and detailed information on mortgage borrowers across these cities, we find enormous housing price appreciation during...

This paper uses the segmented dual-class shares issued by several dozen Chinese firms---A shares to local Chinese investors and H shares to foreign investors---to compare reactions of local and foreign investors to the same public news. We find that local investors react more strongly to...

We develop a model of asset price bubbles based on the communication process between advisors and investors. Advisors are well-intentioned and want to maximize the welfare of their advisees (like a parent treats a child). But only some advisors understand the new technology (the tech-savvies);...

In 2005-08, over a dozen put warrants traded in China went so deep out of the money that they were certain to expire worthless. Nonetheless, each warrant was traded nearly three times each day at substantially inflated prices. This bubble is unique, because the underlying stock prices make the...

This paper models a firm's rollover risk generated by conflict of interest between debt and equity holders. When the firm faces losses in rolling over its maturing debt, its equity holders are willing to absorb the losses only if the option value of keeping the firm alive justifies the cost of...
