We observe the natural log of wage, denoted by lnw lnw , and dummy variables for regions. In the dataset, workers live in one of (1) Northeast, (2) Midwest, (3) South, and (4) West. Let =1 N = 1 if the worker lives in Northeast and =0 N = 0 otherwise, =1 M = 1 if the worker lives in Midwest and =0 M = 0 otherwise, =1 S = 1 if the worker lives in South and =0 S = 0 otherwise, and =1 W = 1 if the worker lives in West and =0 W = 0 otherwise. The regression estimate is lnw=10.90.140.190.09 . lnw = 10.9 0.14 M 0.19 S 0.09 W e . What is the average log wage of workers living in West
