Answer to Question 1

Based on the data, the indicators are:
Y = 0 + 1X1i + 2X2i + 3X3i + 4X4i + 5X5i + i
Where
Yi = wages
X1 = Years of experience
X2 = 1 for Austria, 0 otherwise
X3 = 1 for France, 0 otherwise
X4 = 1 for Germany, 0 otherwise
X5 = 1 for Japan, 0 otherwise
The excluded category consists of wages in the United States.
