Purchasing Power Parity (PPP)

One popular macroeconomic analysis metric to compare economic productivity and standards of living between countries is purchasing power parity (PPP). PPP is an economic theory that compares different countries' currencies through a "basket of goods" approach, not to be confused with the Paycheck Protection Program created by the CARES Act.
