Interest rate - Wikipedia
However, business cycles in every nation show a two-way relation between business investment and interest rates. The accelerator theory explains the positive. Abstract. The main reason of this study is to test the interest rate impact on investment in The results indicate that there is a long-term relationship association. The two main partial models are referring to the impact of investment on GDP growth rate and to the relation between the interest rate and investment.
If he chooses one, he forgoes the returns from all the others.
The Classical Theory of Interest (With Diagarm)
Different investments effectively compete for funds. There is always a risk that the borrower will go bankruptabscond, die, or otherwise default on the loan. This means that a lender generally charges a risk premium to ensure that, across his investments, he is compensated for those that fail.
People prefer to have their resources available in a form that can immediately be exchanged, rather than a form that takes time to realize. Because some of the gains from interest may be subject to taxes, the lender may insist on a higher rate to make up for this loss. Banks can tend to change the interest rate to either slow down or speed up economy growth. This involves either raising interest rates to slow the economy down, or lowering interest rates to promote economic growth.
Interest rates can fluctuate according to the status of the economy. It will generally be found that if the economy is strong then the interest rates will be high, if the economy is weak the interest rates will be low. Non-market-based theories[ edit ] Some economists like Karl Marx argue that interest rates are not actually set purely by market competition. Rather they argue that interest rates are ultimately set in line with social customs and legal institutions.
Effects of MEC and Rate of Interest on Volume of Investment
In many law disputes, where interest has to be calculated, an average rate of interest has to be assumed as the legal rate. Once the MEC becomes equated to the rate of interest, equilibrium investment is determined. Thereafter investment has to be increased, either the rate of interest should fall or MEC should increase.
In this connection D. The rate of interest is very important in the effective implementation of fiscal policy specially debt management. But as a means of affecting private investment it could be of importance as a determinant of income and employmentif the marginal efficiency schedule were highly elastic.
Keynes in the General Theory attributed fluctuations to the changes in expectations and shifts in the MEC and not to the rate of interest. At times this factor may certainly play an aggravating and, occasionally perhaps, an initiating part. But I suggest that a more typical and often the predominant explanation of the crisis is not primarily a rise in the rate of interest, but a sudden collapse in the marginal efficiency of capital.

- Effects of MEC and Rate of Interest on Volume of Investment
The following table depicts clearly the relationship of MEC and the rate of interest in the determination of the inducement to invest: In this table, it is assumed that the new capital asset in question gives a constant return of Rs.
The MEC and the rate of interest are given separately in separate columns, having been determined independently of each other. The position and shape of the investment demand schedule pay a deciding role in determining the volume of investment because it shows the extent to which the amount of investment changes as a result of changes in the rate of interest. If the demand MEC schedule is relatively interest-elastic, a little fall in the rate of interest will lead to a considerable increase in investment.
On the other hand, if the investment demand schedule MEC schedule is relatively inelastic, there will be little increase in investment, though the fall in the rate of interest may be considerable.
There has been a lot of controversy on the extent of interest-elasticity of the investment demand schedule. Experience confirms the views that it tends to be interest-inelastic especially during depression. A change in the marginal efficiency of capital or in the rate of interest, or both, induces a change in the level of investment, as shown in Fig. There are a large number of long-run and short-run factors which influence the marginal efficiency of capital.
We will also go beyond Crusoe and include government borrowing and international trade in our discussion. One thing that makes our task simple is that the resources for investment come from saving.
Therefore, rather than talk about how people decide how much to consume, we will talk about how people determine how much to save. Since income after taxes goes for either consumption or saving, it is a matter of twiddle dee or twiddle dum. Saving and Investment as Different Concepts Many people confuse the concepts of saving and investment.
The differences are important, so we will spend some time on the issue. Saving takes place when people abstain from consumption, that is, when they consume less than their income. Investment takes place when we purchase new capital equipment or other assets that make for future productivity. Investment does not mean buying stocks or bonds.
