We extend the heteroskedasticity IV estimator of Rigobon and Sack (2004) from one to multiple monetary policy shocks by imposing recursive zero restrictions on the impact matrix. Unlike high-frequency identification, the approach requires neither intraday tick data nor precise announcement...

This paper estimates the returns to education in Arkansas - one of the last states to extend compulsory schooling - using ACS 2023 data and the 1987 Compulsory Schooling Law (CSL) reform as an instrument. OLS estimates imply returns of 9.5-10.4 percent per year of schooling. The CSL reform...

We approximate the finite-sample distribution of impulse response function (IRF) estimators that are just-identified with a weak instrument using the conventional local-to-zero asymptotic framework. Since the distribution lacks a mean, we assess bias using the mode and conclude that researchers...
