Asset market hangovers and economic growth
During the early 1990s, asset prices and investment were unusually weak throughout the industrial world. This paper highlights this stylized fact, and connects it with another: in most of the industrial world, asset markets boomed for several years before collapsing around 1989. The paper suggests that the sluggish asset markets and investment growth of the early 1990s may represent, in part, symptoms of an "asset market hangover," that is, the lingering effects on real activity of collapsing speculative bubbles. The analysis relies on cross-country data for equity and real estate markets ...

Duality and arbitrage with transactions costs: theory and applications
Recent advances in duality theory have made it easier to discover relationships between asset prices and the portfolio choices based on them. But this approach to arbitrage-free securities markets has yet to be extended and applied to economies with transactions costs. This paper does so, within the context of a general state-preference model of securities markets. Several applications are developed to illustrate the nature of the theory and its potential to resolve a host of issues surrounding the effects of transactions costs on securities markets.

Inducing agents to report hidden trades: a theory of an intermediary
When contracts are unobserved, agents may have the incentive to promise the same asset to multiple counterparties and subsequently default. The author constructs an optimal mechanism that induces agents to reveal all their trades voluntarily. The mechanism allows agents to report every contract they enter, and it makes public the names of agents who have reached some prespecified position limit. In some cases, an agent's position limit must be higher than the number of contracts he enters in equilibrium. The mechanism has some features of a clearinghouse. ; Supersedes Working Paper 09-10

Interpreting the volatility smile: an examination of the information content of option prices
This paper evaluates how useful the information contained in options prices is for predicting future price movements of the underlying assets. We develop an improved semiparametric methodology for estimating risk-neutral probability density functions (PDFs), which allows for skewness and intertemporal variation in higher moments. We use this technique to estimate a daily time series of risk-neutral PDFs spanning the late 1980's through 1999, for S&P 500 futures, U.S. dollar/Japanese yen futures and U.S. dollar/deutsche mark futures, using options on these futures. For the foreign exchange ...

Macroeconomic state variables as determinants of asset price covariances
This paper explores the possible advantages of introducing observable state variables into risk management models as a strategy for modeling the evolution of second moments. A simulation exercise demonstrates that if asset returns depend upon a set of underlying state variables that are autoregressively conditionally heteroskedastic (ARCH), then a risk management model that fails to take account of this dependence can badly mismeasure a portfolio's "Value-at-Risk" (VaR), even if the model allows for conditional heteroskedasticity in asset returns. Variables measuring macroeconomic news ...
