Duffy-Deno (2003) estimated that the demand function for broadband service was Qs = 15.6p−0.563 for small firms and Ql = 16.0p−0.296 for larger ones. These two demand functions cross. What can you say about the elasticities of demand on the two demand curves at the point where they cross? What can you say about the elasticities of demand more generally (at other prices)? (Hint: The question about the crossing point may be a red herring. Explain why.)

About time delivery co. incurred the following costs related to trucks and vans used in operating its delivery service: classify each of the costs as a capital expenditure or a revenue expenditure. 1. changed the oil and greased the joints of all the trucks and vans. 2. changed the radiator fluid on a truck that had been in service for the past four years. 3. installed a hydraulic lift to a van. 4. installed security systems on four of the newer trucks. 5. overhaul the engine on one of the trucks purchased three years ago. 6. rebuilt the transmission on one of the vans that had been driven 40,000 miles. the van was no longer under warranty. 7. removed a two-way radio from one of the trucks and installed a new radio with a greater range of communication. 8. repaired a flat tire on one of the vans. 9. replaced a truck's suspension system with a new suspension system that allows for the delivery of heavier loads. 10. tinted the back and side windows of one of the vans to discourage theft of contents.

1. the healthy pantry bought new shelving and financed $7,300 with 36 monthly payments of $267.65 each. suppose the firm pays the loan off with 13 payments left. use the rule of 78 to find the amount of unearned interest. 2. the healthy pantry bought new shelving and financed $7,300 with 36 monthly payments of $267.65 each. suppose the firm pays the loan off with 13 payments left. use the rule of 78 to find the amount necessary to pay off the loan. ! i entered 967.82 for question 1 and 5,455.78 for question 2 and it said it was

Suppose a firm faces a fixed price of output, 푝푝= 1200. the firm hires workers from a union at a daily wage, 푤푤, to produce output according to the production function 푞푞= 2퐸퐸12. there are 225 workers in the union. any union worker who does not work for this firm is guaranteed to find nonunion employment at a wage of $96 per day. a.what is the firm’s labor demand function? b.if the firm is allowed to choose 푤푤, but then the union decides how many workers to provide (up to 225) at that wage, what wage will the firm set? how many workers will the union provide? what is the firm’s output and profit? what is the total income of the 225 union workers? c.now suppose that the union sets the wage, but the firm decides how many workers to hire at that wage (up to 225). what wage will the union set to maximize the total income of all 225 workers? how many workers will the firm hire? what is the firm’s output and profit? what is the total income of the 225 union workers? [hint: to maximize total income of union, take the first order condition with respect to w and set equal to 0.]
