We investigate a method for extracting nonlinear principal components. These principal components maximize variation subject to smoothness and orthogonality constraints; but we allow for a general class of constraints and multivariate densities, including densities without compact support and...

We present a novel approach to depicting asset pricing dynamics by characterizing shock exposures and prices for alternative investment horizons. We quantify the shock exposures in terms of elasticities that measure the impact of a current shock on future cash-flow growth. The elasticities are...

Assesses the theories of knowledge spillover and growth proposed by Romer, Porter, and Jacobs by focusing on the largest industries in 170 U.S. cities. While the theories of Romer and Porter both emphasize spillovers within an industry, Romer predicts that a local monopoly is better for growth...

The death of an artist constitutes a negative supply shock to his future produc- tion; in finance terms, this supply shock reduces the artist's float. Intuition may thus suggest that this supply shock reduces the future auction volume of the artist. However, if collectors have fluctuating...

We develop a model of asset price bubbles based on the communication process between advisors and investors. Advisors are well-intentioned and want to maximize the welfare of their advisees (like a parent treats a child). But only some advisors understand the new technology (the tech-savvies);...

We propose a continuous-time model of trading with heterogeneous beliefs. Risk-neutral agents face quadratic costs-of-carry on positions and thus their marginal valuations decrease with the size of their position, as it would be the case for risk-averse agents. In the equilibrium models of...

We study the speculative value of a finitely lived asset when investors disagree and short sales are limited. In this case, investors are willing to pay a speculative value for the resale option they obtain when they acquire the asset. Using martingale arguments, we characterize the equilibrium...

Using enforcements of the Foreign Corrupt Practices Act, we test the hypothesis that socially responsible (ESG) firms receive lower sanctions from prosecutors. Since virtually all cases are settled by bargaining, we estimate sanction specifications derived from a Nash Bargaining model. To...

Asset prices contain information about the probability distribution of future states and the stochastic discounting of those states as used by investors. To better understand the challenge in distinguishing investors' beliefs from risk-adjusted discounting, we use Perron-Frobenius Theory to...

We present a novel approach to depicting asset pricing dynamics by characterizing shock exposures and prices for alternative investment horizons. We quantify the shock exposures in terms of elasticities that measure the impact of a current shock on future cash-flow growth. The elasticities are...
