There are two types of inflation: demand--pull and cost--push. Demand--pull inflation is when rising prices cause too much money "to chase" too few goods. Cosh-Push inflation is when rising prices result from increase in the cost of production caused by the increase of raw materials, the wage-price spiral. Inflation affects people differently; some suffer, others benefit. Those most likely to suffer are people living on relatively fixed incomes, savers, lenders, and businesses.
