Keen beans, a leading coffee roaster, anticipated that the prices of coffee beans from costa rica, where its main suppliers were located, would double in less than three years. this would significantly affect keen beans' profit margins. thus, keen beans decided to develop a new partnership with a supplier in indonesia. as predicted, the price of costa rican coffee beans increased two-fold. because the price of indonesian coffee beans was much lower, keen beans was able to maintain its profit margins in turbulent times. which of the following isolating mechanisms does this scenario best illustrate? a. intellectual-property protection b. causal ambiguityc. time compression diseconomiesd. better expectations of future resource value

Why is the cournot equilibrium an​ equilibrium? a. there are​ short-run barriers to exit in a cournot​ duopoly, so both firms cannot alter their output levels. b. given the other​ firm's level of​ production, both firms are maximizing profits and cannot improve their situation by unilaterally altering their level of output. c. both firms operate at zero profit under a cournot​ equilibrium, so they would face negative profits if they change output. d. both firms operate at minimum​ long-run average cost under a cournot​ equilibrium, so changes to output would reduce​ long-run profits. even if they​ can't collude, why​ don't firms set their outputs at the joint​ profit-maximizing levels​ (i.e., the levels they would have chosen had they​ colluded)? a. given that other firm produces at the collusive​ level, a firm could increase their own profits by increasing output above the collusive level. b. the midpoint of the collusion curve​ (i.e., the collusive​ outcome) lies below the reaction​ curves, so both firms have an incentive to increase output under the cournot duopoly. c. both a and b are correct d. both a and b are incorrect
