This book provides a broad introduction of modern asset pricing theory with equal treatments for both discrete-time and continuous-time modeling. Both the no-arbitrage and the general equilibrium approaches of asset pricing theory are treated coherently within the general equilibrium...

This paper establishes general conditions for the validity of mutual fund separation and the equilibrium CAPM. We use partial preference orders that display weak form mean preserving spread (w-MPS) risk aversion in the sense of Ma (2011). We derive this result without imposing any distributional...

This paper extends Meyer's (1987) location-scale family with general n random seed sources. Firstly, we clarify and generalize existing results to this multivariate setting. Some useful geometrical and topological properties of the location-scale expected utility functions are obtained....

We develop a simple model to address the interaction between security lending market and security trading market. Whether a security is hard to borrow or not results in two different scenarios of the interaction process. When a security is easy to borrow, short-selling leads to a lower spot...

This paper proposes a novel way of pricing S&P500 index options in the presence of jump risk. Our analysis is built upon an equilibrium option pricing rule for a representative agent economy. In particular, we use the weighted utility's certainty equivalent to specify agent's risk preference,...

We develop a theoretical model to study investors' trading behavior in the presence of large shareholders' influence on a firm's equity. We show that, for a good stock, large shareholders may invest a higher proportion of their wealth in the firm than smart small investors, although they predict...

Options are believed to contain unique information about the risk-neutral moment generating function (MGF hereafter) or the risk-neutral probability density function (PDF hereafter). This paper applies the wavelet method to approximate the risk-neutral MGF of the underlying asset from option...

This paper presents the shadow Capital Asset Pricing Model (CAPM) of Ma (2011a) as an intertemporal equilibrium asset pricing model, and tests it empirically. In contrast to the classical CAPM - a single factor model based on a strong behavioral or distributional assumption, the shadow CAPM can...

This paper is on decision theoretical foundations for various types of VaR models, including VaR and conditional-VaR, as objective measures of downside risk for financial prospects. We establish the connections of the VaRs with the first- and the second-order stochastic dominance investment...

We develop a novel approach for the direct extraction of aggregated investor attention and relative risk aversion (RRA) from European option prices. Applying it to China 50ETF options data, we document several noteworthy findings. First, we introduce the option-implied attention (OIA) index,...
