Are rent rates influence by the student population in a college town? let rent be the average monthly rent paid on rental units in a college town in the united states. let pop denote the total city population, avginc the average city income, and the pctstu the student population as a percentage of the total population. one model to test for a relationship is log(rent)=b0 + b1log(pop) + b2log(avginc) + b3(pctstu + u. (1). state the null hypothesis that size of the student body relative to the population has no ceteris paribus effect on monthly rents. state the alternative that there is an effect. (2). what signs do you expert for b1 and b2? (3). the equation estimated using 1990 data rental1.raw for 64 college town is, log(rent)=.043 + .066, log(pop) + .507 log(avginc) + .0056pctstu n=64 r=.458 what is wrong with the statement : a 10% increase in population is associated with about a 6.6% increase in rent. (4). test the hypothesis stated in part (i) at 1% level

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.
