We develop a new parametric estimation procedure for option panels observed with error which relies on asymptotic approximations assuming an ever increasing set of observed option prices in the moneyness- maturity (cross-sectional) dimension, but with a fixed time span. We develop consistent...

The common approach to evaluating a model in the structural VAR literature is to compare the impulse responses from structural VARs run on the data to the theoretical impulse responses from the model. The Sims-Cogley-Nason approach instead compares the structural VARs run on the data to...

The notion of model-free implied volatility (MFIV), constituting the basis for the highly publicized VIX volatility index, can be hard to measure with accuracy due to the lack of precise prices for options with strikes in the tails of the return distribution. This is reflected in practice as the...

We develop asset pricing models' implications for portfolio efficiency when there is conditioning information in the form of a set of lagged instruments. A model of expected returns identifies a portfolio that should be minimum variance efficient with respect to the conditioning information. Our...

We study a general class of models with social interactions that might display multiple equilibria. We propose an estimation procedure for these models and evaluate its efficiency and computational feasibility relative to different approaches taken to the curse of dimensionality implied by the...

Vast amounts of information result from business and consumer search, communication, and transactions. All this information can enhance market efficiency and consumer surplus as firms tailor products to buyers. But, there is increased risk of information loss. What issues should be on the...

A large body of literature has stressed the institution-development nexus as critical in explaining differences in countries%u2019 economic performance. The empirical evidence, however, has been mainly at the aggregate level, associating macro performance with measures of quality of...

This Chapter provides a survey of the economics literature on multi-sided platforms with particular focus on competition policy issues, including market definition, mergers, monopolization, and coordinated behavior. It provides a survey of the general industrial organization theory of...

In this article we introduce an empirical framework to analyze how firm performance is affected by increased globalization. Using this framework we discuss recent work on measuring the impact of various shocks firms face in the global marketplace, such as reductions in trade costs (through...

Online retailers have gained a total price advantage over brick-and-mortar retailers since the formers generally are not required to collect sales tax. Recently, several states have implemented laws requiring that Amazon collect sales tax during checkout. Using transaction-level data, we...
