An economy can produce good 1 using labour and capital and good 2 using labour and land.
Question:
An economy can produce good 1 using labour and capital and good 2 using labour and land. The total supply of labour is 100 units. Given the supply of capital and land, the marginal products of labour for the two goods are as follows:
Workers Employed | MPL in Sector1 | MPL in Sector 2 |
10 | 150 | 140 |
20 | 115 | 105 |
30 | 90 | 85 |
40 | 72 | 70 |
50 | 60 | 60 |
60 | 50 | 52 |
70 | 42 | 45 |
80 | 36 | 40 |
90 | 32 | 37 |
100 | 30 | 36 |
a) Suppose that the price of good 1 is $1 and the price of good 2 is $2. Determine graphically the wage rate and the allocation of labour between the two sectors.
b) Suppose that the relative price of good 2 falls to 1. Repeat a).
c) Calculate the effects of the price change on the income of the specific factors in sectors 1 and 2.
