This study note looks at the difference between disinflation and deflation.

Deflation and disinflation

Disinflation is a decrease in the rate of inflation, while deflation is a decrease in the general price level. In other words, disinflation is a slowdown in the rate at which prices are rising, while deflation is a decrease in prices.

Disinflation can be caused by a number of factors, including:

  • A decrease in aggregate demand. When aggregate demand decreases, businesses produce less and prices tend to fall.
  • An increase in aggregate supply. When aggregate supply increases, businesses can produce more and prices tend to fall.
  • Depreciation of the currency. When a currency depreciates, it makes imports more expensive and exports cheaper. This can lead to a decrease in prices.

Deflation can be caused by a number of factors, including:

  • A decrease in aggregate demand. When aggregate demand decreases, businesses produce less and prices tend to fall.
  • An increase in aggregate supply. When aggregate supply increases, businesses can produce more and prices tend to fall.
  • A decrease in the money supply. When the money supply decreases, there is less money chasing goods and services, which can lead to a decrease in prices.

Disinflation is generally considered to be a positive development, as it indicates that the economy is slowing down and prices are not rising as quickly. Deflation, on the other hand, is generally considered to be a negative development, as it can lead to a decrease in economic activity and job losses.

Here are some real-world examples of disinflation and deflation:

  • Disinflation in the United States. The United States experienced disinflation in the early 1980s. The inflation rate peaked at 14.8% in 1980 and then fell to 3.2% in 1983.
  • Deflation in Japan. Japan experienced deflation in the late 1990s and early 2000s. The inflation rate fell below 0% in 1999 and remained negative for several years.

It is important to note that disinflation and deflation are not always bad. In some cases, they can be a sign that the economy is adjusting to a new equilibrium. However, if disinflation or deflation is severe or prolonged, it can lead to economic problems.
