Gross Domestic Product (GDP) at Purchasing Power Parity (PPP) is an alternative approach to measuring the size of national economies. Similar to GDP at constant prices, it is the sum of all value add of an economy at local prices.  However, the value in local currency is converted to international dollars that have the same purchasing power as a dollar in the United States.  For many outsourcing countries, this PPP approach indicates a relatively larger national economy that provided via the current price approach which converts local currencies to US dollars at prevailing exchange rates.
