Solutions to Exercises

Otherwise they would face different efficient frontiers and most likely would invest different proportions in risky assets.

The answer to a indicates we should care since complete markets are required to guarantee that a Pareto optimal allocation is reached.

All individuals with increasing utility functions prefer A to B. Pareto set is the lower side and the right side of the box, or the upper side and the left side, depending on which MRS is higher. A-D pricing focuses on the concept of states of nature and the pricing of future payoffs conditional on the occurrence of specific intermedizte states. Either way a Pareto optimum is achieved since, with no short sales constraints, the market is complete.

Solutions to Exercises

As a consequence, the increase in price may well lead to a fully rational increase in demand. Of course, the riskneutral probabilities are the same as in b. We can say agent 2 determines the quantities, and agent 1 determines the prices of the AD securities.


The after-trade MRS and utility levels are: The APT is danthjne about beliefs. The opposite will happen to B.

Yes, in a non-expected utility world where there is a preferences for gambling. Convex preferences can exhibit indifference curves with flat spots, strictly convex preferences cannot. A-D security from calls: The two models are equivalent in a one-period exchange economy since then aggregate consumption and wealth is the same. The matrix is the same at each date.

This is true in particular because one would expect the risk free rate to be lower, as the demand for the risk free asset should be higher, and the return on the optimal risky portfolio fijancial be higher, as the more risk averse investors require a higher compensation for the risk they bear. This is a subject of passionate debates that cannot be resolved here.

Targeting readers with backgrounds in economics, Intermediate Financial Theory, Third Edition includes new material on the asset pricing implications of behavioral finance perspectives, recent developments in portfolio choice, derivatives-risk neutral pricing research, and implications of the financial crisis.

Since there is some probability of default, you must set the rate higher than rf in order to insure an expected return equal to rf. Lottery L is preferred to the ”sure lottery” P.


Apply this result to the R. There the similarities are great: This expression can be interpreted as p1 a demand function.

Math Solutions to homework 3. A PO allocation is one such that agent 2 gets smooth consumption. This is not entirely surprising as the security payoffs untermediate more useful to him for consumption smoothing. This relation holds for example with quadratic utility.

P is preferred to L under transformation g. The essential differences are the following: Because of the variance term diminishing utility, consumption should be equated across states for financjal agent.

It simply requires that the observed prices and returns, presumably the product of a large number of agents trading on the basis of heterogeneous beliefs, are consistent in the sense that no arbitrage opportunities are left unexploited. Markets are not complete: Now we will use these observations. Is your work missing from RePEc? There are vanthine ways to solve it.

Provided enough trading instruments exist, the consumption of the risk-averse agent can thus be completely smoothed out and this constitutes a Pareto Optimum.
