st: how to interpret pooled dummy variable d91, d92....

["Joanne Marshall" <jmarshall1982@hotmail.co.uk>]

given the following results from stata,

lwage (dependent variable is log of wage)

educ 0.02
d91    0.03
d92   0.02
d93  0.04
d94    0.06
con    0.33

with base year of 1990, d91 being dummy variable for 1991 etc..
for year 1991, the wage is increased by 3% than 1990
for year 1992, the wage is increased by 2% than 1990 or 1991?

thank you...

my question here is that does the results refered of 1992, 1993 refer to the 
base year 1990, or the previous year?

This is urgent, thank you very much.

Cheers
Jo
