QUESTION 10 If a Cobb Douglas technology (with factors having strictly positive marginal product) has constant returns to scale, then O a. soquants must be linear Ob. Each factor of production has constant marginal product Oc Both factors of production must have decreasing marginal product O d At least on factor of production must have decreasing marginal product Oe. Both factors of production must have constant marginal product

The short run is defined as the period of time: Select one: O a. in which all inputs are fixed O b. in which at least one input is fixed O c. O d. none of the answers provided is correct in which no inputs are fixed
