relationship between inflation deflation and price stability

CPI measure of inflation. The most commonly used measure of inflation is the total consumer price index (CPI). It reflects changes in the average price of a. Oct 25, Other Factors Impacting Inflation; Missing Deflation Post Recession . A relationship between the unemployment rate and prices was first that a stable relationship existed between unemployment and inflation. In economics, inflation is a sustained increase in the general price level of goods and services The opposite of inflation is deflation (negative inflation rate). . This relationship between the over-supply of banknotes and a resulting .. This model suggests that there is a trade-off between price stability and employment.

Also, individuals or institutions with cash assets will experience a decline in the purchasing power of the cash. Increases in the price level inflation erode the real value of money the functional currency and other items with an underlying monetary nature. Debtors who have debts with a fixed nominal rate of interest will see a reduction in the "real" interest rate as the inflation rate rises.

The real interest on a loan is the nominal rate minus the inflation rate. Any unexpected increase in the inflation rate would decrease the real interest rate.

Banks and other lenders adjust for this inflation risk either by including an inflation risk premium to fixed interest rate loans, or lending at an adjustable rate. Negative[ edit ] High or unpredictable inflation rates are regarded as harmful to an overall economy. They add inefficiencies in the market, and make it difficult for companies to budget or plan long-term. Inflation can act as a drag on productivity as companies are forced to shift resources away from products and services to focus on profit and losses from currency inflation.

For instance, inflated earnings push taxpayers into higher income tax rates unless the tax brackets are indexed to inflation. With high inflation, purchasing power is redistributed from those on fixed nominal incomes, such as some pensioners whose pensions are not indexed to the price level, towards those with variable incomes whose earnings may better keep pace with the inflation. Where fixed exchange rates are imposed, higher inflation in one economy than another will cause the first economy's exports to become more expensive and affect the balance of trade.

There can also be negative impacts to trade from an increased instability in currency exchange prices caused by unpredictable inflation. Cost-push inflation High inflation can prompt employees to demand rapid wage increases, to keep up with consumer prices. In the cost-push theory of inflation, rising wages in turn can help fuel inflation.

In the case of collective bargaining, wage growth will be set as a function of inflationary expectations, which will be higher when inflation is high. This can cause a wage spiral. Social unrest and revolts Inflation can lead to massive demonstrations and revolutions. For example, inflation and in particular food inflation is considered as one of the main reasons that caused the —11 Tunisian revolution [57] and the Egyptian revolution[58] according to many observers including Robert Zoellick[59] president of the World Bank.

Hyperinflation If inflation becomes too high, it can cause people to severely curtail their use of the currency, leading to an acceleration in the inflation rate. High and accelerating inflation grossly interferes with the normal workings of the economy, hurting its ability to supply goods.

Hyperinflation can lead to the abandonment of the use of the country's currency for example as in North Korea leading to the adoption of an external currency dollarization. But when prices are constantly changing due to inflation, price changes due to genuine relative price signals are difficult to distinguish from price changes due to general inflation, so agents are slow to respond to them.

The result is a loss of allocative efficiency. Shoe leather cost High inflation increases the opportunity cost of holding cash balances and can induce people to hold a greater portion of their assets in interest paying accounts. However, since cash is still needed to carry out transactions this means that more "trips to the bank" are necessary to make withdrawals, proverbially wearing out the "shoe leather" with each trip.

Menu costs With high inflation, firms must change their prices often to keep up with economy-wide changes. But often changing prices is itself a costly activity whether explicitly, as with the need to print new menus, or implicitly, as with the extra time and effort needed to change prices constantly.

Positive[ edit ] Labour-market adjustments Nominal wages are slow to adjust downwards. This can lead to prolonged disequilibrium and high unemployment in the labor market. Since inflation allows real wages to fall even if nominal wages are kept constant, moderate inflation enables labor markets to reach equilibrium faster. Mundell—Tobin effect The Nobel laureate Robert Mundell noted that moderate inflation would induce savers to substitute lending for some money holding as a means to finance future spending.

That substitution would cause market clearing real interest rates to fall.

In a similar vein, Nobel laureate James Tobin noted that such inflation would cause businesses to substitute investment in physical capital plant, equipment, and inventories for money balances in their asset portfolios. That substitution would mean choosing the making of investments with lower rates of real return. The rates of return are lower because the investments with higher rates of return were already being made before. Unless the economy is already overinvesting according to models of economic growth theorythat extra investment resulting from the effect would be seen as positive.

Causes of Inflation

Instability with deflation Economist S. This report discusses the relationship between unemployment and inflation, the general economic theory surrounding this topic, the relationship since the financial crisis, and its use in policymaking. The Phillips Curve A relationship between the unemployment rate and prices was first prominently established in the late s. This early research focused on the relationship between the unemployment rate and the rate of wage inflation.

Phillips found that between andthere was a negative relationship between the unemployment rate and the rate of change in wages in the United Kingdom, showing wages tended to grow faster when the unemployment rate was lower, and vice versa.

As the unemployment rate decreases, the supply of unemployed workers decreases, thus employers must offer higher wages to attract additional employees from other firms. This body of research was expanded, shifting the focus from wage growth to changes in the price level more generally. Inflation is a general increase in the price of goods and services across the economy, or a general decrease in the value of money.

Conversely, deflation is a general decrease in the price of goods and services across the economy, or a general increase in the value of money. The inflation rate is determined by observing the price of a consistent set of goods and services over time.

In general, the two alternative measures of inflation are headline inflation and core inflation. Headline inflation measures the change in prices across a very broad set of goods and services, and core inflation excludes food and energy from the set of goods and services measured.

Core inflation is often used in place of headline inflation due to the volatile nature of the price of food and energy, which are particularly susceptible to supply shocks. Many interpreted the early research around the Phillips curve to mean that a stable relationship existed between unemployment and inflation. This suggested that policymakers could choose among a schedule of unemployment and inflation rates; in other words, policymakers could achieve and maintain a lower unemployment rate if they were willing to accept a higher inflation rate and vice versa.

This rationale was prominent in the s, and both the Kennedy and Johnson Administrations considered this framework when designing economic policy. These critics claimed that the static relationship between the unemployment rate and inflation could only persist if individuals never adjusted their expectations around inflation, which would be at odds with the fundamental economic principle that individuals act rationally. But, if individuals adjusted their expectations around inflation, any effort to maintain an unemployment rate below the natural rate of unemployment would result in continually rising inflation, rather than a one-time increase in the inflation rate.

This rebuttal to the original Phillips curve model is now commonly known as the natural rate model. The natural rate of unemployment is often referred to as the non-accelerating inflation rate of unemployment NAIRU. When the unemployment rate falls below the natural rate of unemployment, referred to as a negative unemployment gap, the inflation rate is expected to accelerate.

When the unemployment rate exceeds the natural rate of unemployment, referred to as a positive unemployment gap, inflation is expected to decelerate. The natural rate model gained support as s' events showed that the stable tradeoff between unemployment and inflation as suggested by the Phillips curve appeared to break down. Unemploymentby [author name scrubbed]. The CBO estimates the NAIRU based on the characteristics of jobs and workers in the economy, and the efficiency of the labor market's matching process.

The economy is most stable when actual output equals potential output; the economy is said to be in equilibrium because the demand for goods and services is matched by the economy's ability to supply those goods and services. In other words, certain characteristics and features of the economy capital, labor, and technology determine how much the economy can sustainably produce at a given time, but demand for goods and services is what actually determines how much is produced in the economy.

As actual output diverges from potential output, inflation will tend to become less stable. All else equal, when actual output exceeds the economy's potential output, a positive output gap is created, and inflation will tend to accelerate.

When actual output is below potential output, a negative output gap is generated, and inflation will tend to decelerate. Within the natural rate model, the natural rate of unemployment is the level of unemployment consistent with actual output equaling potential output, and therefore stable inflation. How the Output Gap Impacts the Rate of Inflation During an economic expansion, total demand for goods and services within the economy can grow to exceed the economy's potential output, and a positive output gap is created.

As demand grows, firms rush to increase their output to meet this new demand. In the short term though, firms have limited options to increase their output. It often takes too long to build a new factory, or order and install additional machinery, so instead firms hire additional employees. As the number of available workers decreases, workers can bargain for higher wages, and firms are willing to pay higher wages to capitalize on the increased demand for their goods and services.

However, as wages increase, upward pressure is placed on the price of all goods and services because labor costs make up a large portion of the total cost of goods and services. Over time, the average price of goods and services rises to reflect the increased cost of wages. The opposite tends to occur when actual output within the economy is lower than the economy's potential output, and a negative output gap is created.

During an economic downturn, total demand within the economy shrinks. In response to decreased demand, firms reduce hiring, or lay off employees, and the unemployment rate rises. As the unemployment rate rises, workers have less bargaining power when seeking higher wages because they become easier to replace. Firms can hold off on increasing prices as the cost of one of their major inputs—wages—becomes less expensive. This results in a decrease in the rate of inflation. As discussed earlier, the natural rate of unemployment is the rate that is consistent with sustainable economic growth, or when actual output is equal to potential output.

It is therefore expected that changes within the economy can change the natural unemployment rate. Labor market composition, 2. Labor market institutions and public policy, 3.

Long-term—that is, longer than 26 weeks—unemployment rates. Individual worker's characteristics affect the likelihood that a worker will become unemployed and the speed or ease at which he or she can find work. For example, younger workers tend to have less experience and therefore have higher levels of unemployment on average. Consequently, if young workers form a significant portion of the labor force, the natural rate of unemployment will be higher.

Alternatively, individuals with higher levels of educational attainment generally find it easier to find work; therefore, as the average level of educational attainment of workers rises, the natural rate of unemployment will tend to decrease.

For example, apprenticeship programs provide individuals additional work experience and help them find work faster, which can decrease the natural rate of unemployment. Alternatively, ample unemployment insurance benefits may increase the natural rate of unemployment, as unemployed individuals will spend longer periods looking for work. According to economic theory, employee compensation can grow at the same speed as productivity without increasing inflation.

Individuals become accustomed to compensation growth at this speed and come to expect similar increases in their compensation year over year based on the previous growth in productivity.

A decrease in the rate of productivity growth would eventually result in a decrease in the growth of compensation; however, workers are likely to resist this decrease in the pace of wage growth and bargain for compensation growth above the growth rate of productivity.

This above average compensation growth will erode firms' profits and they will begin to lay off employees to cut down on costs, leading to a higher natural rate of unemployment.

Importance of price stability

The opposite occurs with an increase in productivity growth, businesses are able to increase their profits and hire additional workers simultaneously, resulting in a lower natural rate of unemployment. Individuals who are unemployed for longer periods of time tend to forget certain skills and become less productive, and are therefore less attractive to employers. In addition, some employers may interpret long breaks from employment as a signal of low labor market commitment or worker quality, further reducing job offers to this group.
