But for each portfolio the return is the same in each of the two bad market states and the return is the same in each of the two good market states. The result is that each portfolio’s points fall on a curve (here a line). This is a result of great relevance. The only source of uncertainty for either Mario or Hue is the overall return on the market. Each takes only market risk. Non-market risk can be diversified away and neither Mario nor Hue has chosen to take any of it. Thus each of the investors is following the advice of the MRRC.

To be more precise, the absolute value of the slope of a person’s marginal utility curve in a diagram with the log of marginal utility on the vertical axis and the log of consumption on the horizontal axis is his or her relative risk aversion at that point. Mario thus exhibits constant relative risk aversion (CRRA). 5. Later we will see some implications of marginal utility functions of this type. Economists have a term for the slope of a curve when both variables are plotted on logarithmic scales: “In economics, elasticity is the ratio of the incremental percentage change in one variable with respect to an incremental percentage change in another variable.

Mario is willing to buy shares as long as the price is less than 7. His demand curve shows that the lower the price, the more shares he would like to buy. At any price between 5 and 7 the two will be willing to trade HFC shares. In this case, the market maker can concentrate on the range between the two investors’ reservation prices (5 and 7). The quantity demanded will equal the quantity supplied at a price close to 6, the average of Mario and Hue’s reservation prices. 68 shares. The market maker thus announces the trade price is 6, takes orders, and executes the trades.
