Inflation occurs when prices rise over time on average in an economy. It can be caused by increases in the money supply or increases in aggregate demand outpacing aggregate supply. Businesses are impacted by inflation as it erodes purchasing power over time and creates uncertainty. Deflation is when prices fall on average and can occur during recessions or expansions driven by technology. Disinflation is when the inflation rate declines but prices still rise, just not as quickly. The Consumer Price Index (CPI) and GDP price deflator are used to measure inflation.

on business
1.06 Understand economic indicators
to recognize economic trends and
conditions

2. INFLATION
 A persistent increase in the average price level in the
economy.
 It is measured by the inflation rate
 Inflation is the most common phenomenon associated
with the price level.
 Inflation is one of two key macroeconomic problems.
The other is unemployment.

3. Causes of Inflation
 Inflation occurs when the AVERAGE price level
(that is, prices in general) increases over time.
 This does NOT mean that ALL prices increase the same,
nor that ALL prices necessarily increase. Some prices might
increase a lot, others a little, and still other prices decrease
or remain unchanged.
 Inflation results when the AVERAGE of these
assorted prices follows an upward trend.
 While short-term bouts of inflation can be triggered by
anything that would cause aggregate demand to increase
more than aggregate supply
 long-term inflation can be sustained ONLY through
increases in the money supply. The price level, and any
"inflation" of the price level, depends directly on the amount
of money in circulation. On the flip side of this relationship,
inflation leads to a continual erosion in the purchasing
power of money.

4. INFLATION RATE
 The percentage change in the price level from one period
to the next.
 The inflation rate is most commonly presented as an
annual average, the percentage change in the average
price level from one year to the next.
 The two most common price indexes used to measure the
price level and the inflation rate are the Consumer Price
Index (CPI) and the GDP price deflator.
 The inflation rate is one of several key indicators of
business-cycle instability and the overall health of the
macroeconomy, with primary focus on tracking the goal of
price stability.
 The inflation rate, measured as the percentage change in
a price index such as the Consumer Price Index or the
GDP price deflator, seeks to quantify changes in the
average price level.
 While the inflation rate is generally positive, indicating
inflation, it also can be negative, indicating deflation.

5. DEFLATION
 A persistent decrease in the average price level in the economy.
 deflation occurs when the AVERAGE price level decreases over time.
 While some prices might decrease, other prices could increase or remain unchanged,
 deflation occurs if the AVERAGE follows a downward trend.
 Deflation is a rare phenomenon indeed in the economy and typically
happens during prolonged periods of
 (1) contractionary stagnation or
 (2) technological-induced expansion.
 Deflation could appear during a fairly lengthy recession or occasional depression, when
aggregate demand has dried up substantially.
 With no one buying goods, producers reduce prices and deflation results.
 Deflation also can emerge during expansionary periods driven by
significant technological advances, when the economy has the ability to
provide more production at lower cost. Following declining production
cost, the price level also falls and the result is deflation..

6. DISINFLATION
 A decline in the inflation rate.
 prices continue rising, just not as fast.
 Numerically speaking, disinflation occurs if the
inflation rate over three consecutive years is 10
percent, 6 percent this year, and 4 percent.
 a reduction in the inflation rate, is not the same as
deflation, which is an actual decline in the price
level.
 Should disinflation continue, presumably due to
anti-inflationary monetary or fiscal policies, then
the average price level might eventually decline,
making the transition from disinflation to deflation.

7. Problems of Deflation
 create uncertainty and a haphazard redistribution of
income just like inflation.
 Uncertainty
 If prices unexpectedly decline, then consumers and producers
alike might be less willing to pursue long-term activities,
because they just do not know what will happen to the price
level.
 Haphazard Redistribution:
 haphazardly redistribute income and wealth just like inflation.
If some prices decrease more than others, then income and
wealth is redistributed to the owners of those resources with
the smaller price decreases.
 deflation occurs when the aggregate demand for
production persistently falls short of the aggregate supply
of production.
 While a number of factors can trigger such an imbalance,
persistent deflation is only possible in the long run if the

8. CONSUMER PRICE INDEX
 An index of prices of goods and services typically purchased by urban
consumers.
 The Consumer Price Index (CPI) is compiled and published monthly by
the Bureau of Labor Statistics (BLS), using price data obtained from an
elaborate survey of 25,000 retail outlets and quantity data generated by
the Consumer Expenditures Survey.
 The CPI is one of two key price indexes used as a measure of the price
level and to estimate the inflation rate.
 The other is the GDP price deflator.
 The CPI is also officially designated as the Consumer Price Index for All
Urban Consumers (CPI-U).
 Another noted price index is the Producer Price Index (PPI).
 The Consumer Price Index (CPI) is unquestionably one of the most
widely recognized macroeconomic price indexes, running second only
to the Dow Jones Industrial Average in the price index popularity
contest.
 It is used not only as an indicator of the price level and inflation, but also
to convert nominal economic indicators to real terms and to adjust wage
and income payments (such as Social Security) for inflation.
