Suppose capital and labor are perfect substitutes in a long-run production process. If labor costs $15 per hour and the rental rate of capital is $20 per hour, what can we say about the profit maximizing choice of labor and capital inputs?

Michigan mattress company is considering the purchase of land and the construction of a new plant. the land, which would be bought immediately (at t = 0), has a cost of $100,000 and the building, which would be erected at the end of the first year (t = 1), would cost $500,000. it is estimated that the firm's afterminustax cash flow will increase by $100,000 starting at the end of the second year, and that this incremental flow would increase at a 10 percent rate annually over the next 10 years. what is the approximate payback period?

Aprice ceiling is “binding” if the price ceiling is set below the equilibrium price. suppose that the equilibrium price is $5. if a price ceiling is set at $6, this will not affect the market in any way since $5 remains a legally allowable price (since $5 < $6). a price ceiling of $6 is called a “non-binding” price ceiling. on the other hand, if the price ceiling is set at $4, the price ceiling is “binding” because the natural equilibrium price is $5 but that is no longer allowed. what happens when there is a binding price ceiling? at a price below the equilibrium price, quantity demanded exceeds quantity supplied. there is a shortage. normally, price increases eliminate shortages by increasing quantity supplied and decreasing quantity demanded. in this case, however, price increases are not allowed past the price ceiling. we therefore predict that the observed market price will be right at the price ceiling and there will be a permanent shortage. the observed quantity bought and sold will be dictated by the quantity supplied at the price ceiling. although consumers would like to buy more, there are no more units for sale

At the end of the current year, accounts receivable has a balance of $550,000; allowance for doubtful accounts has a credit balance of $5,500; and sales for the year total $2,500,000. an analysis of receivables estimates uncollectible receivables as $25,000. determine the net realizable value of accounts receivable after adjustment. (hint: determine the amount of the adjusting entry for bad debt expense and the adjusted balance of allowance of doubtful accounts.)
