Question 5: Suppose a brewery uses a Cobb-Douglas production function for his production. He studies the production process and finds the following. An additional machine-hour of fermentation capacity would increase output by 500 bottles per day (i.e. MPK = 500). An additional man-hour of labor would increase output by 1000 bottles per day (i.e. MPL = 1000). The price of a man-hour of labor is $50 per hour. The price of a machine-hour of fermentation capacity is $5 per hour. 3. Suppose that the price of a machine-hour of fermentation capacity rises to $25 per hour. How does this change the answer from part 1?

The switch to chip readers was precarious, with many businesses taping over the chip card slots in the terminals until the kinks were worked out. Even after a year, some businesses still could not process chips and continued to utilize the magnetic stripe for transactions. Financial institutions thought the additional security benefits of the chips would overshadow the added wait times. Yet…
