Inflation Rate = Interest Rate + Constant (Edward Conway, 2015).
Abstract (Full text inflation.pdf)
Using consumption based asset pricing under the RUE numeraire, we show that the rate of price inflation in any currency is simply the interest rate of that currency plus a constant. An intuitive explanation for this result is that in an efficient market carry trades cannot be a free lunch. The valuation of any currency will thus tend to drift towards its forward price with time. The higher interest rates are, the lower the forward price will be, and as the value of a currency drifts lower we experience inflation.
