Hidden price cuts are a form of defensive strategy. T F Firms in monopoly have a demand curve that is perfectly inelastic. T F Differences in firm efficiency can weaken collusions. T F When Marginal Cost is equal to Average Total Cost, Marginal Cost is increasing. T F Although the instructor in this course is lousy, the TA is good. T F In economic analysis, the measuring stick is efficiency, defined as valuable output over valuable input. T F The goal of factor-factor decision making is to find the combination of inputs that minimizes costs. T F The end of Stage II, an irrational stage, is where MPP = APP and APP is a maximum. T F An increase in pear production will not affect the demand for pears. T F A goal of compounding is to factor out the time element while a goal of discounting is to get all costs and revenues at the same point in time. T F Marginal costs include fixed and variable costs, but only in the long run. T F If the percentage change in quantity supplied is less than the percentage change in price, then the supply curve is elastic. T F APP is always increasing when we are experiencing increasing returns. T F The upper portion of a “kinked” demand curve for an oligopolist is probably elastic. T F The demand curve in a monopolistically competitive market is very inelastic.
