ثلاثة أساليب مختلفة لتوزيع محفظة ودائع بالعملات الأجنبية في المملكة العربية السعودية : دراسة تطبيقية

Abstract EN

The objective of this research is to shed light on three different approaches related to the allocation of short term investment held in foreign exchange.

This type of portfolio has become more popular after 1973 for Arab Gulf States in general, and Saudi Arabia in particular.

All these countries are developing oil countries.

The research is divided into four sections.

Section one is concerned with Econometric Models, as a tool for Forecasting Future Trends.

Regression analysis to historical data has took place for the period (January 1983 - January 1989).

These forecasts are used for solving problems related to portfolio selection.

Section two stresses using Markov chains as a new approach for this type of investment.

The condition of equilibrium is derived to show the suitability of this technique in the shortrun, and its unsuitability in the long-run.

In section three the study develops a Multi- Objective Programming Model for Optimal Distribution, based on linear programming and computer facilities.

The study also includes practical methods for calculating the degree of Risk and the Real Rate of Return.

The last section analyses and examines these different approaches by using the real rate of return, and it will also sum up the main findings of the study.
