If a typical firm in a perfectly competitive industry is earning profits, then:

If the government is required to balance the budget and the economy falls into a recession, which of the actions is a feasible policy response? cut taxes to encourage consumer spending invest in infrastructure increase government spending to stimulate the economy cut spending equal to the reduction in tax revenue what is a likely consequence of this policy? unemployment falls due to the economic stimulus. the negative consequences of the recession are magnified. consumer spending increases due to their ability to keep more of their after-tax income. there is hyperinflation due to an increase in aggregate demand.

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.

Suppose a country's productivity last year was 84. if this country's productivity growth rate of 5 percent is to be maintained, this means that this year's productivity will have to be:
