In this paper we study identification and estimation of a correlated random coefficients (CRC) panel data model. The …

Data on human height can provide an index that may measure more accurately changes in the standard of living than the more conventional real wage index. Height data, like those on real wages, are relatively abundant and extend back to the seventeenth century. In a previous paper, we developed...

We extend range-based volatility estimation to the multivariate case. In particular, we propose a range …

This paper analyzes the performance of heteroskedasticity-and-autocorrelation-consistent (HAC) covariance matrix estimators in which the residuals are prewhitened using a vector autoregressive (VAR) filter. We highlight the pitfalls of using an arbitrarily fixed lag order for the VAR filter, and...

The problem of how to control for covariates is endemic in evaluation research. Covariate-matching provides an appealing control strategy, but with continuous or high-dimensional covariate vectors, exact matching may be impossible or involve small cells. Matching observations that have the same...

almost all these papers ignore the bias in the estimated standard errors that serial correlation introduce4s. This is … especially troubling because the independent variable of interest in DD estimation (e.g., the passage of law) is itself very … biased: with about 20 years of data, DD estimation finds an 'effect' significant at the 5% level of up to 45% of the placebo …

This paper describes a simple method of calculating a heteroskedasticity and autocorrelation consistent covariance matrix that is positive semi-definite by construction. It also establishes consistency of the estimated covariance matrix under fairly general conditions

We develop estimation methods that use the amount of selection on the observables in a model as a guide to the amount …

We propose a portmanteau test for serial correlation of the error term in a fixed effects model. The test is derived as …

The recent literature on instrumental variables (IV) features models in which agents sort into treatment status on the basis of gains from treatment as well as on baseline-pretreatment levels. Components of the gains known to the agents and acted on by them may not be known by the observing...
