  1. Notes: Standard errors in italic. Each column presents an OLS regression of the fixed-weighted college wage premium on the indicated variables. The college/noncollege wage premium is calculated as the average for each potential experience group. The minimum wage is deflated by the consumer price index. Columns (1) and (2) also include dummy variables for the four potential experience groups used in the Table. The source for labor supply and wages is the Quadros de Pessoal, 1984-2009.
