事實一般也就是當(dāng)成自變量來做就行,前幾天我們replicate O’Neill, J. and D. O’Neill, “What Do Wage Differentials Tell Us about Labor Market Discrimination?”
老師給的command是1. First run a regression where the only explanatory variable is black to get the raw log wage differential and its standard errors. Is it statistically significant?
reg lropc00 black if hispanic==0;
2. Next add some demographic variables:
reg lropc00 black age00 msa ctrlcity north_central south00 if hispanic==0;
3. Then add AFQT scores:
reg lropc00 black
