Jumps and diffusive changes in stock prices are different ways in which information is reflected in the prices. We use nonparametric methods to decompose returns on individual stocks into jumps and diffusive components. Contrary to the conventional assumption that jump intensity is positively...

This paper investigates the interaction between housing prices and housing rentals. Standard economic models treat housing prices as the present discounted value of future rentals with the latter treated as exogenous. Casual observation, however, suggests that changes in rental prices often...

This paper tests the asymptotic arbitrage pricing theory (APT) with the factors extracted from individual stocks. It is shown that the asymptotic APT fails if and only if the number of unbounded eigenvalues of the second-moment matrix of excess returns exceeds that of the variance matrix of...

We investigate the effect of information uncertainty on the macroeconomicannouncement premium of the market return in addition to theeffect of fundamentals uncertainty. We show that the premium issignificant only during low information uncertainty periods, opposite to thecase of fundamentals...

We examine whether and how payout policy affects credit risk using evidence from the credit default swap (CDS) market. CDS spreads increase substantially in response to announcements of dividend cuts, especially during recessions and among firms experiencing financial distress. CDS spreads also...

We propose a new, price-based measure of information risk called abnormal idiosyncratic volatility (AIV) that captures information asymmetry faced by uninformed investors. AIV is the idiosyncratic volatility prior to information events in excess of normal levels. Using earnings announcements as...

We present an analytical framework for the forward-looking measurement of extreme market risk. In contrast to standard techniques relying on past return data, we propose to extract Value-at-Risk and Expected Shortfall under the physical measure from current option prices. Our empirical evidence...
