Demand and Supply
Around the globe, 24 hours per day, impossible-to-regulate currency markets set prices for the U.S. dollar, Japanese yen, and the European Economic and Monetary Union's euro. Much to the chagrin of sovereign governments and their official representatives, minute-by-minute variations in currency prices are wholly determined by the converging forces of supply and demand. For example, U.S. stock markets plunged an unprecedented 684.81 points on Monday, September 17, 2001, following the resumption...

The simple relation between marginal revenue, price, and the point price elasticity is very useful in the setting of pricing policy. To see the usefulness of Equation 5.10 in practical pricing 2 In calculus notation, marginal revenue is the derivative of the total revenue function. That is, MR _ dTR dQ.

Summary 1
Product demand is a critical determinant of profitability, and demand estimates are key considerations in virtually all managerial decisions. This chapter considers methods for quantifying and interpreting demand relations. Elasticity is the percentage change in a dependent variable, Y, resulting from a 1 percent change in the value of an independent variable, X. Point elasticity measures elasticity at a point on a function. Arc elasticity measures the average elasticity over a given range of a...

Theory Of The Firm
At its simplest level, a business enterprise represents a series of contractual relationships that specify the rights and responsibilities of various parties see Figure 1.2 .

Maximin Decision Rule
One decision standard that is sometimes applicable for decision making under uncertainty is the maximin criterion.4 This criterion states that the decision maker should select the alternative that provides the best of the worst possible outcomes. This is done by finding the worst possible minimum outcome for each decision alternative and then choosing the option whose worst outcome provides the highest maximum payoff. This criterion instructs one to maximize the minimum possible outcome. To...
