Accurate company valuation is the starting point of value investing and corporate decisions. This paper proposes a statistical factor model to generate company valuation comparison across a large universe. The model scales the market value of a company by its book capital to generate a...

We analyze the specifications of option pricing models based on time-changed Levy 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 consider the design and estimation of quadratic term structure models. We start with a list of stylized facts on interest rates and interest rate derivatives, classified into three layers: (1) general statistical properties, (2) forecasting relations, and (3) conditional dynamics. We then...

We investigate whether the same finite dimensional dynamic system spans both interest rates (the yield curve) and interest rate options (the implied volatility surface). We find that the options market exhibits factors independent of the underlying yield curve. While three common factors are...

We apply stochastic time change to Levy processes to generate a wide variety of tractable option pricing models. In particular, we prove a fundamental theorem that transforms the characteristic function of the time-changed Levy process into the Laplace transform of the stochastic time under...

We develop a simple robust test for the presence of jumps in the price of an asset underlying an option. Our test examines the prices of at and out-of-the-money options as the time to maturity of the option approaches zero. We show that these prices converge to zero at speeds which depend on...

We identify and characterize a class of term structure models where bond yields are quadratic functions of the Markov process. We label this class as the 'quadratic class' and aim to lay a solid theoretical foundation for its future empirical application. We contribute to the literature in three...

This paper develops a dynamic general equilibrium asset pricing model to account for the discontinuous price movements commonly observed in the financial markets. We consider two possible sources: (1) jumps in the fundamental economy, as captured by the production technology, and (2) jumps in...

A central feature of the asset return data is non-normality, which raises important questions about asset allocation. This paper provides a general framework for analyzing optimal dynamic asset allocation problems in economies with infrequent events and where the investment opportunities are...

The pricing kernel, or the state-price density, which relates future cash flows to today's price, is the fundamental building block of modern asset pricing theory. In abstract, the state-price density process can be regarded as a positive supermartingale, or, under some regularity conditions, a...
