The GDP function chooses the most efficient point on the production possibility frontier with curved surface. We derive a three-sector Cobb–Douglas GDP function including three goods (agriculture, manufacturing, and services) and three factors (capital, labor, and land). It is very difficult...

This paper presents a new approach to the two-sector optimal taxation problem. We derive the optimal labor income tax rate which depends on factor intensity across sectors. It is the labor intensity that determines the initial wage rate, and therefore the optimal labor tax rate. We show that an...
