This article estimates a forward-looking Taylor-rule-type reaction function exclusively during Greenspan's tenure and shows a considerable loss in both magnitude and significance of the inflation coefficient compared with the extended sample that otherwise includes Volcker's tenure. That fact...

This paper provides new evidence of the short and long-run effects of vocational training (VT) on labor market and educational outcomes, with a particular interest in how school quality may confound estimates. VT schools may differ from regular schools not only in terms of type of training, but...

This paper compares water and sanitation services in municipalities that entered into a concession arrangement with a private operator versus those in a comparable control group of municipalities that continued with a public operator, and we explore five variables of interest: (i) water coverage;...
