Abstract: Declaring a currency to be mispriced is fraught with uncertainties. In this presentation, I describe a new approach that explicitly recognises these uncertainties. I use a model of the price of a homogeneous commodity in different countries that allows for a common driver of prices, due to a base-currency effect, and country-specific factors leading to departures from absolute purchasing power parity on account of income differences, local taxes and charges, etc. This gives rise to an estimate of currency mispricing and its standard error. I then use the model with Big Mac prices to estimate the degree of mispricing of the Australian dollar.
