Chapter 7 & 8 Chapter 7: Problems 1, 6, 8, and 9 1. In the Deep Creek Mining Company example described in this chapter (Table 7.1), suppose again that labor is the variable input and capital is the fixed input. Specifically, assume that the firm owns a piece of equipment having a 500-bhp rating. a.

Some of the problems that one might encounter using time-series data to estimate the parameters of this model, could be the change in the number of buses that are taken out of service each year. This is because only certain buses are taken out which means that they would not be any consistency in the amount of buses taken out. Another problem could be are all the buses. Another problem could be the condition of the bus, the bus may not be as old, but may cause problems and are taken out of service and might affect the average range of miles. Chapter 8: Problems 2(a), 4, and 6(a) 2(a) Howard Brown is a large-scale cotton farmer. The land and machinery he owns has a current market value of $4 million. Bowen owes his local bank $3 million. Last year Bowen sold $5 million worth of cotton. His variable operating costs were $4.5 million; accounting depreciation was $40,000, although the actual decline in value of Bowen’s machinery was $60,000 last year. Bowen paid himself a salary of $50,000, which is not considered part of his variable operating costs. Interest on his bank loan was $400,000. If Bowen worked for another farmer or a local manufacturer, his annual income would be about $30,000. Bowen can invest any funds that would be derived, if the farm were sold, to earn 10 percent annually. (Ignore taxes.) Compute Bowmen’s accounting profits. Revenues
