In economics, stagflation or recession-inflation is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. It presents a dilemma for economic policy, since actions intended to lower inflation may exacerbate unemployment.


The term, a portmanteau of stagnation and inflation , is generally attributed to Iain Macleod, a British Conservative Party politician who became Chancellor of the Exchequer in 1970. Macleod used the word in a 1965 speech to Parliament during a period of simultaneously high inflation and unemployment in the United Kingdom. [1] [2] [3] [4] Warning the House of Commons of the gravity of the situation, he said:

"We now have the worst of both worlds—not just inflation on the one side or stagnation on the other, but both of them together. We have a sort of 'stagflation' situation. And history, in modern terms, is indeed being made." [3] [5]

Macleod used the term again on 7 July 1970, and the media began also to use it, for example in The Economist on 15 August 1970, and Newsweek on 19 March 1973. John Maynard Keynes did not use the term, but some of his work refers to the conditions that most would recognise as stagflation. In the version of Keynesian macroeconomic theory that was dominant between the end of World War II and the late 1970s, inflation and recession were regarded as mutually exclusive, the relationship between the two being described by the Phillips curve. Stagflation is very costly and difficult to eradicate once it starts.

The term stagflation, a portmanteau of stagnation and inflation , was first coined during a period of inflation and unemployment in the United Kingdom. The United Kingdom experienced an outbreak of inflation in the 1960s and 1970s. As inflation rose then, British policy makers failed to recognise the primary role of monetary policy in controlling inflation. Instead, they attempted to use non-monetary policies and devices to respond to the economic crisis. Policy makers also made "inaccurate estimates of the degree of excess demand in the economy, [which] contributed significantly to the outbreak of inflation in the United Kingdom in the 1960s and 1970s." [3]

Stagflation was not limited to the United Kingdom, however. Economists have shown that stagflation was prevalent among seven major market economies from 1973 to 1982. [6] After inflation rates began to fall in 1982, economists' focus shifted from the causes of stagflation to the "determinants of productivity growth and the effects of real wages on the demand for labor".

Economists offer two principal explanations for why stagflation occurs. First, stagflation can result when the economy faces a supply shock, such as a rapid increase in the price of oil. An unfavourable situation like that tends to raise prices at the same time as it slows economic growth by making production more costly and less profitable. [7] [8] [9] [10]

Second, the government can cause stagflation if it creates policies that harm industry while growing the money supply too quickly. These two things would probably have to occur simultaneously because policies that slow economic growth do not usually cause inflation, and policies that cause inflation do not usually slow economic growth.[ citation needed ]

Supply shock

At the start of the Six-Day War when Israel invaded the Sinai Peninsula all the way down to the Suez Canal. The Egyptian President Gamal Abdel Nasser, who was aligning with the Soviet Union, closed down the Suez Canal for eight years starting in 1967 as soon as the Six-Day War broke out. Oil through the Suez Canal from the Middle East to Europe had to be rerouted around the Continent of Africa. When Egypt tried to cross the Suez Canal and take back the Sinai Peninsula in the Yom Kippur War in late 1973, that is what triggered the Oil embargo in October 1973, when Richard Nixon supported funding Israel with $2.2 billion over the conflict. That resulted in OAPEC countries cutting production of oil and placing an embargo on oil exports to the United States and other countries backing Israel. [11] [12]

Money supply in the early 1970s increased at almost 15% year over year in the United States and the Consumer price index lags behind about one year or two. Britains monetary policy was also dovish causing excess demand. [13] [14]

In the mid 1970s the Bretton Woods system was failing and countries fixed exchange rate system between currencies started to float, and the Gold standard where currencies were pegged to gold was abandoned. The price of gold and oil became very volatile after many years of steadiness. [15] [16]

Other reasons

A wide range of diverse evidence has been compiled supporting the second explanation against the supply shock view that the 1970s stagflation was due to OPEC’s quadrupling of oil prices in October 1973. Data show that its seeds were sown during the late sixties and began to be reaped in that decade. Between 1968 and 1970 unemployment rose from 3.6% to 4.9% while the CPI inflation rose from 4.7% to 5.6%. [17] Further in the Michigan survey expected inflation rose from 3.8% to 4.9% between 1967 and 1970. The rise in expected inflation strongly supports the view that Expected Augmented Phillips Curve (EAPC) can explain the early, mild stagflation. Although the weakening economy was putting some downward pressure on inflation overall inflation rose in accordance with EAPC, as expected inflation kept rising. The stagflation became more severe in the early 1970s but was suppressed by the price controls and wage freeze imposed by President Nixon starting in August 1971 and through 1972. But when the controls were lifted in mid-1973 the CPI surged to 8.5%. Arguably, if there were no wage-price controls, the mini stagflation documented above would have been clearly evident before the October 1973 OPEC oil price hike. [18]

As for the direct impact of dollar depreciation on inflation, data again imply that just as higher inflation shifted up the labor supply curve and made workers demand and get higher money wages, similarly a falling dollar made commodity producers demand higher prices to compensate for the dollar decline. Further, the weakening of the dollar, while exogeneous to oil prices, was itself a delayed response to rising inflation from 1968 onwards. This pattern of an overheated economy, leading to inflation, dollar depreciation, and then to higher oil prices and another bout of stagflation repeated itself in 1979. [18]

Both explanations are offered in analyses of the 1970s stagflation in the West. It began with a large rise in oil prices, but then continued as central banks used excessively stimulative monetary policy to counteract the resulting recession, thereby causing a price/wage spiral. [19]

Increased requirements on skill (education and experience) on work force, for example because of increased technical complexity, can cause shortage on skilled employees and rising salaries for them, at the same time as uneducated work tasks have in part moved to low salary countries such as in Asia, causing high unemployment.

Postwar Keynesian and monetarist views

Early Keynesianism and monetarism

Up to the 1960s, many Keynesian economists ignored the possibility of stagflation, because historical experience suggested that high unemployment was typically associated with low inflation, and vice versa (this relationship is called the Phillips curve). The idea was that high demand for goods drives up prices, and also encourages firms to hire more; and likewise, high employment raises demand. However, in the 1970s and 1980s, when stagflation occurred, it became obvious that the relationship between inflation and employment levels was not necessarily stable: that is, the Phillips relationship could shift. Macroeconomists became more sceptical of Keynesian theories, and Keynesians themselves reconsidered their ideas in search of an explanation for stagflation. [20]

The explanation for the shift of the Phillips curve was initially provided by the monetarist economist Milton Friedman, and also by Edmund Phelps. Both argued that when workers and firms begin to expect more inflation, the Phillips curve shifts up (meaning that more inflation occurs at any given level of unemployment). In particular, they suggested that if inflation lasted for several years, workers and firms would start to take it into account during wage negotiations, causing workers' wages and firms' costs to rise more quickly, thus further increasing inflation. While this idea was a severe criticism of early Keynesian theories, it was gradually accepted by most Keynesians, and has been incorporated into New Keynesian economic models.


Neo-Keynesian theory distinguished two distinct kinds of inflation: demand-pull (caused by shifts of the aggregate demand curve) and cost-push (caused by shifts of the aggregate supply curve). Stagflation, in this view, is caused by cost-push inflation. Cost-push inflation occurs when some force or condition increases the costs of production. This could be caused by government policies (such as taxes) or from purely external factors such as a shortage of natural resources or an act of war.

Contemporary Keynesian analyses argue that stagflation can be understood by distinguishing factors that affect aggregate demand from those that affect aggregate supply. While monetary and fiscal policy can be used to stabilise the economy in the face of aggregate demand fluctuations, they are not very useful in confronting aggregate supply fluctuations. In particular, an adverse shock to aggregate supply, such as an increase in oil prices, can give rise to stagflation. [21]

Supply theory


Supply theories are based on the neo-Keynesian cost-push model and attribute stagflation to significant disruptions to the supply side of the supply-demand market equation, such as when there is a sudden real or relative scarcity of key commodities, natural resources, or natural capital needed to produce goods and services. [22] In this view, stagflation is thought to occur when there is an adverse supply shock (for example, a sudden increase in the price of oil or a new tax) that causes a subsequent jump in the "cost" of goods and services (often at the wholesale level). In technical terms, this results in contraction or negative shift in an economy's aggregate supply curve. [23]

In the resource scarcity scenario (Zinam 1982), stagflation results when economic growth is inhibited by a restricted supply of raw materials. [24] [25] That is, when the actual or relative supply of basic materials (fossil fuels (energy), minerals, agricultural land in production, timber, etc.) decreases and/or cannot be increased fast enough in response to rising or continuing demand. The resource shortage may be a real physical shortage, or a relative scarcity due to factors such as taxes or bad monetary policy influencing the "cost" or availability of raw materials. This is consistent with the cost-push inflation factors in neo-Keynesian theory (above). The way this plays out is that after supply shock occurs, the economy first tries to maintain momentum. That is, consumers and businesses begin paying higher prices to maintain their level of demand. The central bank may exacerbate this by increasing the money supply, by lowering interest rates for example, in an effort to combat a recession. The increased money supply props up the demand for goods and services, though demand would normally drop during a recession.[ citation needed ]

In the Keynesian model, higher prices prompt increases in the supply of goods and services. However, during a supply shock (i.e., scarcity, "bottleneck" in resources, etc.), supplies do not respond as they normally would to these price pressures. So, inflation jumps and output drops, producing stagflation.[ citation needed ]

Explaining the 1970s stagflation

Following Richard Nixon's imposition of wage and price controls on 15 August 1971, an initial wave of cost-push shocks in commodities were blamed for causing spiraling prices. The second major shock was the 1973 oil crisis, when the Organization of Petroleum Exporting Countries (OPEC) constrained the worldwide supply of oil. [26] Both events, combined with the overall energy shortage that characterised the 1970s, resulted in actual or relative scarcity of raw materials. The price controls resulted in shortages at the point of purchase, causing, for example, queues of consumers at fuelling stations and increased production costs for industry. [27]

Recent views

Through the mid-1970s, it was alleged that none of the major macroeconomic models (Keynesian, New Classical, and monetarist) were able to explain stagflation. [28]

Later, an explanation was provided based on the effects of adverse supply shocks on both inflation and output. [29] According to Blanchard (2009), these adverse events were one of two components of stagflation; the other was "ideas"—which Robert Lucas, Thomas Sargent, and Robert Barro were cited as expressing as "wildly incorrect" and "fundamentally flawed" predictions (of Keynesian economics) which, they said, left stagflation to be explained by "contemporary students of the business cycle". [30] In this discussion, Blanchard hypothesizes that the recent oil price increases could trigger another period of stagflation, although this has not yet happened (pg. 152).

Neoclassical views

A purely neoclassical view of the macroeconomy rejects the idea that monetary policy can have real effects. [31] Neoclassical macroeconomists argue that real economic quantities, like real output, employment, and unemployment, are determined by real factors only. Nominal factors like changes in the money supply only affect nominal variables like inflation. The neoclassical idea that nominal factors cannot have real effects is often called monetary neutrality [32] or also the classical dichotomy .

Since the neoclassical viewpoint says that real phenomena like unemployment are essentially unrelated to nominal phenomena like inflation, a neoclassical economist would offer two separate explanations for 'stagnation' and 'inflation'. Neoclassical explanations of stagnation (low growth and high unemployment) include inefficient government regulations or high benefits for the unemployed that give people less incentive to look for jobs. Another neoclassical explanation of stagnation is given by real business cycle theory, in which any decrease in labour productivity makes it efficient to work less. The main neoclassical explanation of inflation is very simple: it happens when the monetary authorities increase the money supply too much. [33]

In the neoclassical viewpoint, the real factors that determine output and unemployment affect the aggregate supply curve only. The nominal factors that determine inflation affect the aggregate demand curve only. [34] When some adverse changes in real factors are shifting the aggregate supply curve left at the same time that unwise monetary policies are shifting the aggregate demand curve right, the result is stagflation.

Thus the main explanation for stagflation under a classical view of the economy is simply policy errors that affect both inflation and the labour market. Ironically, a very clear argument in favour of the classical explanation of stagflation was provided by Keynes himself. In 1919, John Maynard Keynes described the inflation and economic stagnation gripping Europe in his book The Economic Consequences of the Peace . Keynes wrote:

Lenin is said to have declared that the best way to destroy the Capitalist System was to debauch the currency. By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens. By this method they not only confiscate, but they confiscate arbitrarily; and, while the process impoverishes many, it actually enriches some. [...] Lenin was certainly right. There is no subtler, no surer means of overturning the existing basis of society than to debauch the currency. The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner which not one man in a million is able to diagnose.

Keynes explicitly pointed out the relationship between governments printing money and inflation.

The inflationism of the currency systems of Europe has proceeded to extraordinary lengths. The various belligerent Governments, unable, or too timid or too short-sighted to secure from loans or taxes the resources they required, have printed notes for the balance.

Keynes also pointed out how government price controls discourage production.

The presumption of a spurious value for the currency, by the force of law expressed in the regulation of prices, contains in itself, however, the seeds of final economic decay, and soon dries up the sources of ultimate supply. If a man is compelled to exchange the fruits of his labours for paper which, as experience soon teaches him, he cannot use to purchase what he requires at a price comparable to that which he has received for his own products, he will keep his produce for himself, dispose of it to his friends and neighbours as a favour, or relax his efforts in producing it. A system of compelling the exchange of commodities at what is not their real relative value not only relaxes production, but leads finally to the waste and inefficiency of barter.

Keynes detailed the relationship between German government deficits and inflation.

In Germany the total expenditure of the Empire, the Federal States, and the Communes in 1919–20 is estimated at 25 milliards of marks, of which not above 10 milliards are covered by previously existing taxation. This is without allowing anything for the payment of the indemnity. In Russia, Poland, Hungary, or Austria such a thing as a budget cannot be seriously considered to exist at all. Thus the menace of inflationism described above is not merely a product of the war, of which peace begins the cure. It is a continuing phenomenon of which the end is not yet in sight.

Zimmermann conclusion

While most economists believe that changes in money supply can have some real effects in the short run, neoclassical and neo-Keynesian economists tend to agree that there are no long-run effects from changing the money supply. Therefore, even economists who consider themselves neo-Keynesians usually believe that in the long run, money is neutral. In other words, while neoclassical and neo-Keynesian models are often seen as competing points of view, they can also be seen as two descriptions appropriate for different time horizons. Many mainstream textbooks today treat the neo-Keynesian model as a more appropriate description of the economy in the short run, when prices are 'sticky', and treat the neoclassical model as a more appropriate description of the economy in the long run, when prices have sufficient time to adjust fully. [35]

Therefore, while mainstream economists today might often attribute short periods of stagflation (not more than a few years) to adverse changes in supply, they would not accept this as an explanation of very prolonged stagflation. More prolonged stagflation would be explained as the effect of inappropriate government policies: excessive regulation of product markets and labour markets leading to long-run stagnation, and excessive growth of the money supply leading to long-run inflation.[ citation needed ]

Alternative views

As differential accumulation

Political economists Jonathan Nitzan and Shimshon Bichler have proposed an explanation of stagflation as part of a theory they call differential accumulation, which says firms seek to beat the average profit and capitalisation rather than maximise. According to this theory, periods of mergers and acquisitions oscillate with periods of stagflation. When mergers and acquisitions are no longer politically feasible (governments clamp down with anti-monopoly rules), stagflation is used as an alternative to have higher relative profit than the competition. With increasing mergers and acquisitions, the power to implement stagflation increases.

Stagflation appears as a societal crisis, such as during the period of the oil crisis in the 70s and in 2007 to 2010. Inflation in stagflation, however, does not affect all firms equally. Dominant firms are able to increase their own prices at a faster rate than competitors. While in the aggregate no one appears to profit, differentially dominant firms improve their positions with higher relative profits and higher relative capitalisation. Stagflation is not due to any actual supply shock, but because of the societal crisis that hints at a supply crisis. It is mostly a 20th and 21st century phenomenon that has been mainly used by the "weapondollar-petrodollar coalition" creating or using Middle East crises for the benefit of pecuniary interests. [36]

Demand-pull stagflation theory

Demand-pull stagflation theory explores the idea that stagflation can result exclusively from monetary shocks without any concurrent supply shocks or negative shifts in economic output potential. Demand-pull theory describes a scenario where stagflation can occur following a period of monetary policy implementations that cause inflation. This theory was first proposed in 1999 by Eduardo Loyo of Harvard University's John F. Kennedy School of Government. [37]

Supply-side theory

Supply-side economics emerged as a response to US stagflation in the 1970s. It largely attributed inflation to the ending of the Bretton Woods system in 1971 and the lack of a specific price reference in the subsequent monetary policies (Keynesian and Monetarism). Supply-side economists asserted that the contraction component of stagflation resulted from an inflation-induced rise in real tax rates (see bracket creep). [23]

Austrian School of economics

Adherents to the Austrian School maintain that creation of new money ex nihilo benefits the creators and early recipients of the new money relative to late recipients. Money creation is not wealth creation; it merely allows early money recipients to outbid late recipients for resources, goods, and services. Since the actual producers of wealth are typically late recipients, increases in the money supply weakens wealth formation and undermines the rate of economic growth. Austrian economist Frank Shostak says: "The increase in the money supply rate of growth coupled with the slowdown in the rate of growth of goods produced is what the increase in the rate of price inflation is all about. (Note that a price is the amount of money paid for a unit of a good.) What we have here is a faster increase in price inflation and a decline in the rate of growth in the production of goods. But this is exactly what stagflation is all about, i.e., an increase in price inflation and a fall in real economic growth. Popular opinion is that stagflation is totally made up. It seems therefore that the phenomenon of stagflation is the normal outcome of loose monetary policy. This is in agreement with [Phelps and Friedman (PF)]. Contrary to PF, however, we maintain that stagflation is not caused by the fact that in the short run people are fooled by the central bank. Stagflation is the natural result of monetary pumping which weakens the pace of economic growth and at the same time raises the rate of increase of the prices of goods and services." [38]

Jane Jacobs and the influence of cities on stagflation

In 1984, journalist and activist Jane Jacobs proposed the failure of major macroeconomic theories [notes 1] to explain stagflation was due to their focus on the nation as the salient unit of economic analysis, rather than the city. [39] She proposed that the key to avoiding stagflation was for a nation to focus on the development of "import-replacing cities" that would experience economic ups and downs at different times, providing overall national stability and avoiding widespread stagflation. According to Jacobs, import-replacing cities are those with developed economies that balance their own production with domestic imports—so they can respond with flexibility as economic supply and demand cycles change. While lauding her originality, clarity, and consistency, urban planning scholars have criticised Jacobs for not comparing her own ideas to those of major theorists (e.g., Adam Smith, Karl Marx) with the same depth and breadth they developed, as well as a lack of scholarly documentation. [40] Despite these issues, Jacobs' work is notable for having widespread public readership and influence on decision-makers. [41]


Stagflation undermined support for the Keynesian consensus.

Federal Reserve chairman Paul Volcker very sharply increased interest rates from 1979 to 1983 in what was called a "disinflationary scenario". After U.S. prime interest rates had soared into the double-digits, inflation did come down; these interest rates were the highest long-term prime interest rates that had ever existed in modern capital markets. [42] Volcker is often credited with having stopped at least the inflationary side of stagflation, although the American economy also dipped into recession. Starting in approximately 1983, growth began a recovery. Both fiscal stimulus and money supply growth were policy at this time. A five- to six-year jump in unemployment during the Volcker disinflation suggests Volcker may have trusted unemployment to self-correct and return to its natural rate within a reasonable period.[ citation needed ]

The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States.

Full employment is a situation in which there is no cyclical or deficient-demand unemployment. Full employment does not entail the disappearance of all unemployment, as other kinds of unemployment, namely structural and frictional, may remain. For instance, workers who are "between jobs" for short periods of time as they search for better employment are not counted against full employment, as such unemployment is frictional rather than cyclical. An economy with full employment might also have unemployment or underemployment where part-time workers cannot find jobs appropriate to their skill level, as such unemployment is considered structural rather than cyclical. Full employment marks the point past which expansionary fiscal and/or monetary policy cannot reduce unemployment any further without causing inflation.

In economics and political science, fiscal policy is the use of government revenue collection and expenditure to influence a country's economy. The use of government revenue expenditures to influence macroeconomic variables developed in reaction to the Great Depression of the 1930s, when the previous laissez-faire approach to economic management became unworkable. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorised that government changes in the levels of taxation and government spending influence aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation and to increase employment. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.

Neutrality of money is the idea that a change in the stock of money affects only nominal variables in the economy such as prices, wages, and exchange rates, with no effect on real variables, like employment, real GDP, and real consumption. Neutrality of money is an important idea in classical economics and is related to the classical dichotomy. It implies that the central bank does not affect the real economy by creating money. Instead, any increase in the supply of money would be offset by a proportional rise in prices and wages. This assumption underlies some mainstream macroeconomic models. Others like monetarism view money as being neutral only in the long run.

The policy-ineffectiveness proposition (PIP) is a new classical theory proposed in 1975 by Thomas J. Sargent and Neil Wallace based upon the theory of rational expectations, which posits that monetary policy cannot systematically manage the levels of output and employment in the economy.

Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.

<span class="mw-page-title-main">History of macroeconomic thought</span> Aspect of history

Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.

<span class="mw-page-title-main">New neoclassical synthesis</span> Fusion of macroeconomic schools of thought

The new neoclassical synthesis (NNS), which is now generally referred to as New Keynesian economics, and occasionally as the New Consensus, is the fusion of the major, modern macroeconomic schools of thought – new classical macroeconomics/real business cycle theory and early New Keynesian economics – into a consensus view on the best way to explain short-run fluctuations in the economy. This new synthesis is analogous to the neoclassical synthesis that combined neoclassical economics with Keynesian macroeconomics. The new synthesis provides the theoretical foundation for much of contemporary mainstream macroeconomics. It is an important part of the theoretical foundation for the work done by the Federal Reserve and many other central banks.
