A firm can use three different production technologies, with capital and labor requirements at each level of output as follows:

	TECHNOLOGY 1		TECHNOLOGY 2		TECHNOLOGY 3
Daily
Output	K	L	K	L	K	L
100	3	7	4	5	5	4
150	3	10	4	7	5	5
200	4	11	5	8	6	6
250	5	13	6	10	7	8

a. Suppose the firm is operating in a high-wage country, where capital cost is $100 per unit per day and labor cost is $80 per worker per day. For each level of output, which technology is the cheapest?

b. Now suppose the firm is operating in a low-wage country, where capital cost is $100 per unit per day but labor cost is only $40 per unit per day. For each level of output, which technology is the cheapest?

c. Suppose the firm moves from a high-wage to a low-wage country but its level of output remains constant at 200 units per day. How will its total employment change?
