They may also find it difficult to decide what to charge for their products in the future. Inflation makes it difficult to see what a price increase really means. When one price rises and all others stay the same, this is sending a signal to the market. However, if a price rises during a period of high inflation, it is hard to tell if it is a signal or if it is due to inflation. If the price increase is due not to inflation but to increased demand for lemons, it would be worthwhile for Kim to try and sell more lemons.
Inflation can hurt savers.
When you put money into a savings account, your reward is the interest your money earns. To maintain the purchasing power of your money, the interest rate will have to be at least as high as inflation. Otherwise your money will not buy as much in the future. If interest rates do not keep up with inflation, people will get little reward for saving. Having fewer people saving is not good for the growth of the economy.
