Talk:Real interest rate

To all Users: Caveat Emptor

Twice I have tried to get Mr Newberry's comments on issues I have with this page. He has refused both times, and twice rudely erased my input to replace his own. He clearly thinks this is his own personal page. He doesn't need to be correct. Retail Investor 21:13, 18 September 2006 (UTC)

Things I have changed

I have deleted the following because taxes are not part of the subject. "This simple definition is much more complicated in practice. For example, if the recipient of the interest has to pay income tax, it is usually levied on the nominal interest rate, and so the tax rate will also affect the real interest rate. "

I have rewritten the following to make it more understandable. "The real interest rate is the nominal interest rate minus the inflation rate. It is a better measure of the return that a lender receives (or the cost to the borrower) because it takes into account the fact that the value of money changes due to inflation over the course of the loan period. This distinction is particularly important in periods when inflation is high, and is more likely to be ignored when inflation is low (e.g., under 2 percent)."

Dear Stirling Newberry

Before I use the revert process, I'll say what my problem is with your input. The factors you specify for compensation by interest, all apply to all interest. They would be correctly detailed on the page "Interest rate". This page is a sub-set of the bigger set. The whole point of this subset is not the factors that remain included... the point is the factor that is excluded = inflation. Nobody wanting to find out what factors can be charged out as interest will search for "real interest rate". They will search "interest rate".

I agree that to explain what 'real' interest is, you have to explain what nominal interest is, but I did that clearly and concisely. I am trying to do some housecleaning here.

As far as your statements the 'real' interest rates require a "currency adjustment" and an "adjustment for compounding"  : I can't see where you got that thought. Can you explain? (yes, I do understand what each of those are)

To be technically correct

Since inflation 'works' upon real rates, the relationship is multiplactive, not additive. E.g. if inflation is 2% and nominal interest is 5%, the real rate is not (5-2=)3%. It is 2.941%.

$\$1\left(1+real\%\right)\left(1+inflation\%\right)=\left(\$1+nominal\%\right)$ $\$1\left(1+2.941\%\right)\left(1+2\%\right)=\$1.05\%$

$\,\!r_{nom}=\left(1+r_{real}\right)\left(1+i\right)-1\approx r_{real}+i$, where $r_{nom}$ is the nominal risk-free rate, $r_{real}$ is the real risk-free rate, and $i$ is the expected inflation rate.

Hi, I believe in the third paragraph where it states, "Conversely, when the real rate of interest is low, demand will move from savings to investment and consumption." It should read; Conversely, when the real rate of interest is low, demand will move from savings and investment to consumption.
