stagflation

Stagflation is a combination of the words “stagnation” and “inflation.” It is a term used by economists to describe a situation where high inflation and low growth combine to produce high unemployment. The most recent period of stagflation occurred during the Jimmy Carter administration in the late 1970s.

One sign of stagflation is when bond yields decrease while the value of gold increases, as is occurring in mid-2011 under the Obama regime.

Snippet from Wikipedia: Stagflation

In economics, stagflation or recession-inflation is a situation in which the inflation rate is high, 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. 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.

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, both in social terms and in budget deficits.

In the version of Keynesian macroeconomic theory which was dominant between the end of WWII 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, in human terms as well as in budget deficits.

In the political arena, one measure of stagflation, termed the Misery Index (derived by the simple addition of the inflation rate to the unemployment rate), was used to swing presidential elections in the United States in 1976 and 1980.

The Great Inflation

The term stagflation was first coined <ref group=notes>“On 7 July 1970 again in the UK Parliament Macleod also used the term stagflation referring to the UK economy. The media began to use it, for example in The Economist (15 August 1970). Paul Samuelson used stagflation first in his Newsweek (19 March 1973) entitled ‘What’s Wrong?’. See Nelson and Nikolov (2002).</ref> 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 early as 17 November 1965, Iain Macleod, the spokesman on economic issues for the United Kingdom’s Conservative Party, warned of the gravity of the UK economic situation in the House of Commons: “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.”<ref name=BankofEngland2002 /><ref name=stagflation>

</ref>

With these words, Macleod coined the term ‘stagflation’.(2) In a Bank of England working papers series article authors, Edward Nelson and Kalin Nikolov, (2002) examined causes and policy errors related to the Great Inflation in the United Kingdom in the 1970s, arguing that as inflation rose in the 1960s and 1970s, UK policy makers failed to recognize that the primary role of monetary policy in controlling inflation and instead 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, contributed significantly to the outbreak of inflation in the United Kingdom in the 1960s and 1970s.<ref name=BankofEngland2002 />

Causes

Economists offer two principal explanations for why stagflation occurs. First, stagflation can result when the productive capacity of an economy is reduced by an unfavorable supply shock, such as an increase in the price of oil for an oil importing country. Such an unfavorable supply shock tends to raise prices at the same time that it slows the economy by making production more costly and less profitable.<ref name=“delong”>

</ref><ref name=“halltaylor”>

</ref> Milton Friedman famously described this situation as “too much money chasing too few goods”.

Second, both stagnation and inflation can result from inappropriate macroeconomic policies. For example, central banks can cause inflation by permitting excessive growth of the money supply,<ref>Blanchard (2000), op. cit., Ch. 9, pp. 172–173, and Ch. 23, pp. 447–450.</ref> and the government can cause stagnation by excessive regulation of goods markets and labour markets.<ref>Blanchard (2000), op. cit., Ch. 22-2, pp. 434–436.</ref> Either of these factors can cause stagflation. Excessive growth of the money supply taken to such an extreme that it must be reversed abruptly can clearly be a cause. Both types of explanations are offered in analyses of the global stagflation of the 1970s: it began with a huge rise in oil prices, but then continued as central banks used excessively stimulative monetary policy to counteract the resulting recession, causing a runaway price/wage spiral.<ref>

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 skeptical of Keynesian theories, and the Keynesians themselves reconsidered their ideas in search of an explanation of stagflation.<ref>Blanchard (2000), op. cit., Chap. 28, p. 541.</ref>

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-Keynesianism

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.<ref name=“abelbernanke”>

Supply theory

Fundamentals

Supply theories<ref>

</ref> 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, for example, when there is a sudden real or relative scarcity of key commodities, natural resources, or natural capital needed to produce goods and services. Other factors may also cause supply problems, for example, social and political conditions such as policy changes, acts of war, extremely restrictive government control of production (For example monopolising Dictatorships).

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.

In the resource scarcity scenario (Zinam 1982), stagflation results when economic growth is inhibited by a restricted supply of raw materials.<ref>

</ref><ref>

</ref> 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 which have affected 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 will first try to maintain momentum – that is, consumers and businesses will begin paying higher prices in order 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.

In the Keynesian model, higher prices will prompt increases in the supply of goods and services. However, during a supply shock (i.e. scarcity, “bottleneck” in resources, etc.), supplies don't respond as they normally would to these price pressures. So, inflation jumps and output drops, producing stagflation.

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 was blamed for causing spiraling prices. Perhaps the most notorious factor cited at that time was the failure of the Peruvian anchovy fishery in 1972, a major source of livestock feed.<ref name=“richfed”>

</ref> The second major shock was the 1973 oil crisis, when the Organization of Petroleum Exporting Countries (OPEC) constrained the worldwide supply of oil.<ref>

</ref> 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.<ref>(

</ref>

Theoretical responses

Under this set of theories, the solution to stagflation is to restore the supply of materials. In the case of a physical scarcity, stagflation is mitigated either by finding a replacement for the missing resources or by developing ways to increase economic productivity and energy efficiency so that more output is produced with less input. For example, in the late 1970s and early 1980s, the scarcity of oil was relieved by increases in both energy efficiency and global oil production. This factor, along with adjustments in monetary policies, helped end stagflation.

Recent views

Until recently no macroeconomic policy had been able to predict the occurrence of stagflation.

After the fact, and several years of research, a convincing explanation was provided based on the effects of adverse supply shocks on both prices and output.<ref name=“blanchard”>

</ref> According to Blanchard (2009), these adverse events were one of two components of stagflation; the other was “ideas”, which Robert Lucas (famous for the Lucas Supply Curve), 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”.<ref name=“blanchard”>

</ref> 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<ref>Abel & Bernanke (1995), op. cit., Ch. 11.</ref> of the macroeconomy rejects the idea that monetary policy can have real effects. 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”<ref>Abel & Bernanke (1995), op. cit., Ch. 11, pp. 378–9.</ref> 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.<ref name=“barrogrilli”>

Ch. 8, Fig. 8.1.</ref>

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.<ref>Abel & Bernanke (1995), Ch. 11, pp. 376–7.</ref> 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.”

Keynesian in the short run, classical in the long run

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.

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 labor markets leading to long-run stagnation, and excessive growth of the money supply leading to long-run inflation.

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, doesn't 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 be profiting, 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.<ref>

</ref>

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.<ref>

://www.nber.org/~confer/99/efcesi99/loyo.pdf</ref>

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)

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. Says Austrian economist Frank Shostak:

“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.”<ref name=“shostak”>

Responses

Stagflation undermined support for Keynesian consensus. The rise of conservative theories of economics, including monetarism, can be traced to the failure of Keynesian policies to combat stagflation or explain it to the satisfaction of economists and policy-makers.

Federal Reserve chairman Paul Volcker very sharply increased interest rates from 1979–1983 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.<ref>

</ref> 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.
