Money and inflation
In emerging countries and China, there is still a link, albeit weaker, between monetary creation and inflation. The explanatory model of long-term inflation remains the transaction money model, with a robust link between nominal income and the money supply. But in OECD countries there appears to no longer be a link between monetary creation and inflation. The explanatory model in these countries has become the portfolio choice model; in this model, an increase in the money supply leads to a rise in prices of financial and real estate assets, not the prices of goods. It seems, therefore, that money is still used for transactions in emerging countries whereas it has become a financial investment in OECD countries.
