This article combines the continuous arrival of information with the infrequency of trades and investigates the effects on asset price dynamics of positive- and negative-feedback trading. Specifically, the authors model an economy where stocks and bonds are traded by two types of agents:...

A cash-in-advance model of a monetary economy is used to derive a money-based capital asset pricing model (M-CAPM), which allows the authors to implement tests of asset pricing restrictions without consumption data. A test as in Eugene F. Fama and James D. Macbeth (1973) of the model suggests...

type="main" <title type="main">ABSTRACT</title> <p>We propose two data-based performance measures for asset pricing models and apply them to models with recursive utility and habits. Excess returns on risky securities are reflected in the pricing kernel's dispersion and riskless bond yields are reflected in its dynamics. We...</p>

We develop a simple robust method to distinguish the presence of continuous and discontinuous components in the price of an asset underlying options. Our method examines the prices of at-the-money and out-of-the-money options as the option's time-to-maturity approaches zero. We show that these...

We analyze the specifications of option pricing models based on time-changed Lévy processes. We classify option pricing models based on the structure of the jump component in the underlying return process, the source of stochastic volatility, and the specification of the volatility process...

We document a surprising pattern in S&P 500 option prices. When implied volatilities are graphed against a standard measure of moneyness, the implied volatility smirk does not flatten out as maturity increases up to the observable horizon of two years. This behavior contrasts sharply with the...
