The sample of candidates for undergraduate programs at UFPE is restricted to those who graduated from high school in the year that they took the college entrance exam and were under 18.5 years old. The first-round score is standardized, with mean zero and variance one, with respect to the whole set of candidates taking the exam at the same time. Annual earnings are deflated to December 2006 level using the National Consumer Price Index (INPC)
