B) it sees an increase in worker productivity. C) it can produce more output using the same inputs. D) it produces less pollution in its production process. 2) If a producer is not able to expand its plant capacity immediately, it is 2) A) operating in the long run. B) bankrupt. C) losing money. D) operating in the short run. 3) The marginal product of labor is defined as 3) A) the additional number of workers required to produce one more unit of output. B) the cost of hiring one more worker. C) the additional output that results when one more worker is hired, holding all other resources constant. D) the additional sales revenue that results when one more worker is hired. 4) If four workers can produce 18 chairs a day and five can produce 20 chairs a day, the marginal product of the fifth worker is A) 2 chairs. B) 3 chairs. C) 4 chairs. D) 38 chairs. 4) 5) The law of diminishing marginal returns states 5) A) that at some point, adding more of a variable input to a given amount of a fixed input will cause the marginal product of the variable input to decline. B) average total costs of production initially fall and after some point starts to rise at a decreasing rate as output increases. C) that at some point, adding more of a fixed input to a given amount of variable inputs will cause the marginal product of the variable input to decline. D) that in the presence of a fixed factor, at some point average product of labor starts to fall as more and more variable inputs are added. 1
