This paper shows how to bootstrap hypothesis tests in the context of the Parks (Efficient estimation of a system of regression equations when disturbances are both serially and contemporaneously correlated 1967) estimator. It then demonstrates that the bootstrap outperforms Parks's top...

In his 2008 Journal of Health Economics paper, Jochen Hartwig claimed that Baumol’s Cost Disease (BCD) theory could explain observed increases in health care expenditures in OECD countries. This paper replicates Hartwig’s results and demonstrates that he tested the wrong hypothesis. When one...

This paper shows how to bootstrap hypothesis tests in the context of the Parks’s (1967) Feasible Generalized Least Squares estimator. It then demonstrates that the bootstrap outperforms FGLS(Parks)’s top competitor. The FGLS(Parks) estimator has been a workhorse for the analysis of panel...
