This paper uses data from a recent, high quality household survey for the Philippines, the 1998 Annual Poverty Indicator Survey (APIS), to test the fit of the long-linear specification for Filipino men. The results are based on a number of estimation strategies, including spline regressions, and semi-parametric regressions with a large number of dummies for years of schooling and experience. The basic conclusions of the paper are two. First, there appear to be large differences between the rates of return to education across levels in the Philippines. In particular, the returns to both primary and secondary education are lower than those for tertiary education, a difference which persists even after correcting for differences in direct private costs across levels. Second, within a given level, the last year of schooling is disproportionately rewarded in terms of higher wages. That is, there are clear sheepskin effects associated with graduation from primary school, secondary school, and university. - Reproduced.  aWages  aOxford Bulletin of Economics and Statistics  a57240  c57240d57240  00104070aIIPAbIIPAd2018-07-19hVolume no: 65, Issue no: 2pAR57685r2018-07-19w2018-07-19yAR
