In north korea, a farmer’s income is the same as a dentist’s income. in a country with a mixed or market economy, the difference between those two professions might be more than 5 times different. how can you explain the fact that individuals doing the same work in different countries do not earn comparable salaries?

Draw a flowchart for a process of interest to you, such as a quick oil-change service, a factory process you might have worked in, ordering a pizza, renting a car or truck, buying products on the internet, or applying for an automobile loan. identify the points where something (people, information) waits for service or is held in work-in-process inventory, the estimated time to accomplish each activity in the process, and the total flow time. evaluate how well the process worked and what might be done to improve it.

1. consider a two-firm industry. firm 1 (the incumbent) chooses a level of output qı. firm 2 (the potential entrant) observes qı and then chooses its level of output q2. the demand for the product is p 100 q, where q is the total output sold by the two firms which equals qi +q2. assume that the marginal cost of each firm is zero. a) find the subgame perfect equilibrium levels of qi and q2 keeping in mind that firm 1 chooses qi first and firm 2 observes qi and chooses its q2. find the profits of the two firms-n1 and t2- in the subgame perfect equilibrium. how do these numbers differ from the cournot equilibrium? b) for what level of qi would firm 2 be deterred from entering? would a rational firm 1 have an incentive to choose this level of qi? which entry condition does this market have: blockaded, deterred, or accommodated? now suppose that firm 2 has to incur a fixed cost of entry, f> 0. c) for what values of f will entry be blockaded? d) find out the entry deterring level of q, denoted by q1', a expression for firm l's profit, when entry is deterred, as a function of f. for what values of f would firm 1 use an entry deterring strategy?
