We propose two new jump-robust estimators of integrated variance based on high-frequency return observations. These MinRV and MedRV estimators provide an attractive alternative to the prevailing bipower and multipower variation measures. Specifically, the MedRV estimator has better theoretical...

This paper describes a simple yet powerful methodology to decompose asset returns sampled at high frequency into their base components (continuous, small jumps, large jumps), determine the relative magnitude of the components, and analyze the finer characteristics of these components such as the...

Time series data are widely used to explore causal relationships, typically in a regression framework with lagged dependent variables. Regression-based causality tests rely on an array of functional form and distributional assumptions for valid causal inference. This paper develops a...

This paper shows that the asymptotic normal approximation is often insufficiently accurate for volatility estimators based on high frequency data. To remedy this, we compute Edgeworth expansions for such estimators. Unlike the usual expansions, we have found that in order to obtain meaningful...

In the United States, the rate of price inflation falls in recessions. Turning this observation into a useful inflation … forecasting equation is difficult because of multiple sources of time variation in the inflation process, including changes in Fed … policy and credibility. We propose a tightly parameterized model in which the deviation of inflation from a stochastic trend …

Recently a market in options based on CPI inflation (inflation caps and floors) has emerged in the US. This paper uses … quotes on these derivatives to construct probability densities for inflation. We study how these pdfs respond to news … empirical pricing kernels. The options-implied densities assign considerably more mass to extreme inflation outcomes (either …

This paper develops and applies semiparametric econometric methods to estimate the form of selection bias that arises from using nonexperimental comparison groups to evaluate social programs and to test the identifying assumptions that justify three widely-used classes of estimators and our...
