Chapter 29 is about the causes and costs of inflation (whose primary cause is the increase in amount of money in circulation). More money, more problems. Therefore, in order to maintain stable prices, the central bank must have strict control over the amount of money in circulation, so as not to cause inflation. The overall level of prices in an economy adjusts to bring money supply and money demand into balance., When the central bank increases the supply of money, it causes the price level to rise. Persistent growth in the quantity of money supplied leads to inflation.
The principle of monetary neutrality says that changes in the quantity of money influence nominal but no real variables, also, most economists believe that monetary neutrality describes the economic behavior in the long run.
A government can pay for its spending by printing money, which leads to an inflation tax. This can lead to hyperinflation.
The Fisher Effect is an application of the principle of monetary neutrality because when the inflation rate rises, the nominal interest rate rises by the same amount.
Many people think that inflation makes them poorer but inflation not only increases the cost of what they buy but also the nominal incomes.
There are six costs on inflation shoeleather costs associated with reduced money holdings, menu costs associated with more frequent adjustment of prices, increased variability of relative prices, unintended changes in tax liabilities due to non indexation of the tax code, confusion, and inconvenience resulting from a changing unit of account.
