The role of money in the balance of payments adjustments process has been cast aside by the so-called traditional approaches to balance of payments adjustments. “The monetary approach to the balance of payments, which was developed over the years at the University of Chicago by economist like R. A. Mundell, H.

G. Johnson, A. B. Laffer and J. A. Frenkel and advanced by the work of International Monetary Fund economists, seeks to restore the role of money and money balances in the adjustment process.

The balance of payments is viewed as essentially a monetary phenomenon, and the imbalances are rooted in the relationship between the demand and the supply of money. “(Chatterji, 2005) It is very simple matters to transform OPT into an unconstrained optimization problem OPT. This is desirable because powerful mathematical algorithms for solving unconstrained problems are available. It is so easy that the computer can do this in a matter that is transport to the user, as implemented in the package OPT design.And to do the transformation of OPT1 to OPT we use the formula in combination with the performance ? (w. z). Suppose T is as in defining a new performance function as follows. ?1(w.

z1) = ? (w. A(jw) + B ( jw) z1) = ?( w. z ) Therefore OPT1 is equivalent to the following unconstrained optimization problem: OPT Given ?1 (w. z), a positive-valued function of w ? R and of z ? C, find ?1 = inf sup ? 1 ( w.

T1 ( jw)) T1 ? ? w And find an optimal T1 if it exists.The current account balance, being the net outcome of sources and uses of foreign currency for current purposes, is much less transparent. Indeed, it is curious that an imbalance on the current account in the balance of payments is sometimes regarded as detrimental and sometimes beneficial depending on the focus of the analysis.

In the particular, if the current account balance is viewed as a net use of foreign exchange, deficits have often been taken to signal problems for macroeconomic policy, particularly exchange rate management.On the other hand, when a perspective recognizing that current account imbalances allow for differences to exist between national investment and saving is taken, a favorable judgment is often made. When international flows of financial capital are tightly and effectively controlled, the current account balance becomes the only factor making for fluctuations in the balance of payments. If current account transactions imply a greater demand for foreign exchange than supply at the given exchange rate, this deficit can be made up either by borrowing from foreigners or depletion of reserves of foreign currency.The current account balance is then a critical variable for economic policy.

If the current account deficit is persistently greater than the available capital inflow, one or both of these policies must be adopted to reduce this deficit, or the exchange rate must be adjusted. The market portfolio is not observable and also that the test of its efficiency is essentially a test of whether or not the proxy used for the market portfolio is mean-variance-efficient.As for a test of portfolio efficiency we must test depending on the estimation of the CSR given to be refereed to as an excess-return version of equation that is Ru is the return in excess of the risk less rate and E ( R1) is the corresponding expected excess return. In this case equation is: A1 = 0 for i = 1, 2,,,,N Curiously enough, such a well-known equilibrium theory as uncovered interest parity is quite often misinterpreted in econometric analysis. One should remember that it is a one-period model; and great care is needed when specifying precisely what happens at the end of that period and at its beginning.One-period models in economics are actually very tricky. To put the same point in another way: uncovered interest parity is a difference equation, in continuous time a differential equation.

What will happen, furthermore, if we wish to examine not only one interest change, but a whole series of them? It turns out that it is not at all a trivial exercise to convert uncovered interest parity into a sequential model of not one, but a succession of many interest rate shocks. Let us restate the interest parity condition, equation and renumber it equation:There are two basic approaches to exchange rate determination; the goods market approach and the asset market approach. While in the goods market approach the idea is that exchange rates are determined basically through the trade of real assets, the asset market approach points to the importance of capital flows. The concept of purchasing power parity (PPP) states that the exchange rate equates the national price levels of two countries in the sense that the PPP of a unit of currency is the same in both countries.A theory of exchange rate determination, it asserts that the exchange rate change between two currencies over any period of time is determined by the change in two countries’ relative price levels.

Factor analysis factors were rotated graphically, a large number of factors it is a tedious and lengthy process. Since mathematical analytic methods of rotation have been developed in which the calculations can be performed, coefficient that appears in a factor pattern matrix, in an analysis that results in oblique components, an analysis that results in orthogonal components.One component has been retained in an analysis; the interpretation of an unrotated factor pattern is usually quite difficult. To make it easier to explain it’s normally performed in an operation called rotation which is a linear transformation that is performed on the factor solution. Proc factor allows you to request several types of rotation and in this analysis ill make use of the varimax rotation an orthogonal rotation, which means its results in uncorrelated components. It tends to maximize the variance of a column of the factor pattern matrix.

This rotation is probably the most commonly used orthogonal rotation in the social sciences.
