Thank you.

The variable that is collinear with the year dummies is actually variable that has constant values in each year (it is different in each year but the same value for each of the years) and hence is perfectly linearly predicted by the year dummies. What is the implication when the dropped dummies are at either end of the sample, that is first and last year?
