## 金融代写|利率理论代写portfolio theory代考|OUTLINE OF THE BOOK

This book is divided into five parts. The first part provides background material on securities and financial markets. The reader already familiar with these topics can go directly to Part 2 .
The second and longest part deals with the subject of portfolio analysis. Portfolio analysis is concerned with finding the most desirable group of securities to hold, given the properties of each of the securities. This part of the book is itself divided into four sections. The first of these sections is titled “Mean Variance Portfolio Theory.” This section deals with determining the properties of combinations (portfolios) of risky assets given the properties of the individual assets, delineating the characteristics of portfolios that make them preferable to others, and, finally, showing how the composition of the preferred portfolios can be determined.
At the end of this section readers will know almost all that they need to know about the theory of portfolio selection. This theory is more than 50 years old. In the ensuing years, a tremendous amount of work has been devoted to implementing this theory. The second section of Part 2 is concerned with the implementation and simplification of portfolio theory. The topics covered include simplifying the quantity and type of input needed to do portfolio analysis and simplifying the computational procedure used to find the composition of the efficient portfolios.

The third section of Part 2 deals with the selection of that one portfolio that best meets the needs of an investor. We discuss not only techniques that rely on utility maximization but also other techniques suggested in the literature.

The final section of Part 2 deals with the impact of the opportunity to diversify a stock portfolio across international boundaries. As the reader might suspect, any increase in the set of possible investment opportunities should increase portfolio performance.

Part 3 deals with models of equilibrium prices and returns in the capital markets. If investors behave as portfolio theory suggests they should, then their actions can be aggregated to determine prices at which securities will sell.

The first two chapters of Part 3 deal with some alternative forms of equilibrium relationships. Different assumptions about the characteristics of capital markets and the way investors behave lead to different models of equilibrium. The third chapter in this part of the book deals with empirical tests of how well these theoretical models describe reality. The final chapter in Part 3 presents both the theoretical basis of and empirical evidence on the newest theory of relative prices: the Arbitrage Pricing Theory.

## 金融代写|利率理论代写portfolio theory代考|THE ECONOMIC THEORY OF CHOICE

All decision problems have certain elements in common. Any problem involves the delineation of alternatives, the selection of criteria for choosing among those alternatives, and, finally, the solution of the problem. Furthermore, individual solutions can often be aggregated to describe equilibrium conditions that prevail in the marketplace. A large part of this book will be concerned with following these steps for the selection of risky assets. But before we start this problem, let us examine a simpler one, under certainty, to illustrate the elements of the solution to any economic problem.
