A magic bag contains infinitely many balls labeled 1 to n with each ball being equally likely to be drawn from the bag. There are also n boxes labeled 1 to n. Suppose you fill the boxes by choosing a random ball from the magic bag. A match occurs when the ball labeled i is placed in the box labeled i. For an arbitrary k in {0,1,...,n} what is the probability that you have k matches? What is the probability...

Suppose a manufacturer (upstream monopolist labeled u) sells a product to a retailer (downstream monopolist labeled d). Assume the manufacturer’s marginal cost of production is c = 20, while the retailer’s marginal cost is simply the wholesale price w set by the manufacturer. (i.e. w is just a transfer price across sectors). Moreover, denote the quantity produced by upstream firm u by X and the quantity sold by the downstream retailer d to consumers by Q. Consumer’s demand for the...
