We introduce a "bad environment-good environment" technology for consumption growth in a consumption-based asset pricing model. Using the preference structure from Campbell and Cochrane (1999), the model generates realistic non-Gaussian features of fundamentals while still permitting closed-form...

We examine whether stock prices fully reflect the value of firms' intangible assets, focusing on research and development (R&D). Since intangible assets are not reported on financial statements under current U.S. accounting standards and R&D spending is expensed, the valuation problem may be...

We evaluate the performance of different models for the covariance structure of stock returns, focusing on their use for optimal portfolio selection. Comparisons are based on forecasts of future covariances as well as the out-of-sample volatility of optimized portfolios from each model. A few...
