Business cycle

Last updated

Business cycles are intervals of expansion followed by recession in economic activity. They have implications for the welfare of the broad population as well as for private institutions. Typically business cycles are measured by applying a band pass filter to a broad economic indicator such as Real Gross Domestic Production. Here important problems may arise with a commonly used filter called the "ideal filter". For instance if a series is a purely random process without any cycle, an "ideal" filter, better called a block filter, a spurious cycle is produced as output. Fortunately methods such as [Harvey and Trimbur, 2003, Review of Economics and Statistics] have been designed so that the band pass filter may be adapted to the time series at hand. [1]

Business cycle fluctuations are usually characterized by general upswings and downturns in a span of macroeconomic variables. The individual episodes of expansion/recession occur with changing duration and intensity over time. Typically their periodicity has a wide range from around 2 to 10 years (the technical phrase "stochastic cycle" is often used in statistics to describe this kind of process.) Such flexible knowledge about the frequency of business cycles can actually be included in their mathematical study, using a Bayesian statistical paradigm. [2]

There are numerous sources of business cycle movements such as rapid and significant changes in the price of oil or variation in consumer sentiment that affects overall spending in the macroeconomy and thus investment and firms' profits. Usually such sources are unpredictable in advance and can be viewed as random "shocks" to the cyclical pattern. In past decades economists and statisticians have learned a great deal about business cycle fluctuations by researching the topic from various perspectives.

The first systematic exposition of economic crises, in opposition to the existing theory of economic equilibrium, was the 1819 Nouveaux Principes d'économie politique by Jean Charles Léonard de Sismondi. [3] Prior to that point classical economics had either denied the existence of business cycles, [4] blamed them on external factors, notably war, [5] or only studied the long term. Sismondi found vindication in the Panic of 1825, which was the first unarguably international economic crisis, occurring in peacetime.[ citation needed ]

Sismondi and his contemporary Robert Owen, who expressed similar but less systematic thoughts in 1817 Report to the Committee of the Association for the Relief of the Manufacturing Poor, both identified the cause of economic cycles as overproduction and underconsumption, caused in particular by wealth inequality. They advocated government intervention and socialism, respectively, as the solution. This work did not generate interest among classical economists, though underconsumption theory developed as a heterodox branch in economics until being systematized in Keynesian economics in the 1930s.

Sismondi's theory of periodic crises was developed into a theory of alternating cycles by Charles Dunoyer, [6] and similar theories, showing signs of influence by Sismondi, were developed by Johann Karl Rodbertus. Periodic crises in capitalism formed the basis of the theory of Karl Marx, who further claimed that these crises were increasing in severity and, on the basis of which, he predicted a communist revolution.[ citation needed ] Though only passing references in Das Kapital (1867) refer to crises, they were extensively discussed in Marx's posthumously published books, particularly in Theories of Surplus Value . In Progress and Poverty (1879), Henry George focused on land's role in crises – particularly land speculation – and proposed a single tax on land as a solution.

In 1860 French economist Clément Juglar first identified economic cycles 7 to 11 years long, although he cautiously did not claim any rigid regularity. [7] Later[ when? ], economist Joseph Schumpeter argued that a Juglar cycle has four stages:

  1. Expansion (increase in production and prices, low interest rates)
  2. Crisis (stock exchanges crash and multiple bankruptcies of firms occur)
  3. Recession (drops in prices and in output, high interest-rates)
  4. Recovery (stocks recover because of the fall in prices and incomes)

Schumpeter's Juglar model associates recovery and prosperity with increases in productivity, consumer confidence, aggregate demand, and prices.

In the 20th century, Schumpeter and others proposed a typology of business cycles according to their periodicity, so that a number of particular cycles were named after their discoverers or proposers: [8]

Economic cycle.svg
Proposed economic waves
Cycle/wave namePeriod (years)
Kitchin cycle (inventory, e.g. pork cycle)3–5
Juglar cycle (fixed investment)7–11
Kuznets swing (infrastructural investment)15–25
Kondratiev wave (technological basis)45–60

Some say interest in the different typologies of cycles has waned since the development of modern macroeconomics, which gives little support to the idea of regular periodic cycles. [11]

Others, such as Dmitry Orlov, argue that simple compound interest mandates the cycling of monetary systems. Since 1960, World GDP has increased by fifty-nine times, and these multiples have not even kept up with annual inflation over the same period. Social Contract (freedoms and absence of social problems) collapses may be observed in nations where incomes are not kept in balance with cost-of-living over the timeline of the monetary system cycle.

The Bible (760 BCE) and Hammurabi's Code (1763 BCE) both explain economic remediations for cyclic sixty-year recurring great depressions, via fiftieth-year Jubilee (biblical) debt and wealth resets[ citation needed ]. Thirty major debt forgiveness events are recorded in history including the debt forgiveness given to most European nations in the 1930s to 1954. [12]

There were great increases in productivity, industrial production and real per capita product throughout the period from 1870 to 1890 that included the Long Depression and two other recessions. [13] [14] There were also significant increases in productivity in the years leading up to the Great Depression. Both the Long and Great Depressions were characterized by overcapacity and market saturation. [15] [16]

Over the period since the Industrial Revolution, technological progress has had a much larger effect on the economy than any fluctuations in credit or debt, the primary exception being the Great Depression, which caused a multi-year steep economic decline. The effect of technological progress can be seen by the purchasing power of an average hour's work, which has grown from $3 in 1900 to $22 in 1990, measured in 2010 dollars. [17] There were similar increases in real wages during the 19th century. (See: Productivity improving technologies (historical) .) A table of innovations and long cycles can be seen at: Kondratiev wave § Modern modifications of Kondratiev theory.

There were frequent crises in Europe and America in the 19th and first half of the 20th century, specifically the period 1815–1939. This period started from the end of the Napoleonic wars in 1815, which was immediately followed by the Post-Napoleonic depression in the United Kingdom (1815–30), and culminated in the Great Depression of 1929–39, which led into World War II. See Financial crisis: 19th century for listing and details. The first of these crises not associated with a war was the Panic of 1825. [18]

Business cycles in OECD countries after World War II were generally more restrained than the earlier business cycles. This was particularly true during the Golden Age of Capitalism (1945/50–1970s), and the period 1945–2008 did not experience a global downturn until the Late-2000s recession. [19] Economic stabilization policy using fiscal policy and monetary policy appeared to have dampened the worst excesses of business cycles, and automatic stabilization due to the aspects of the government's budget also helped mitigate the cycle even without conscious action by policy-makers. [20]

In this period, the economic cycle – at least the problem of depressions – was twice declared dead. The first declaration was in the late 1960s, when the Phillips curve was seen as being able to steer the economy. However, this was followed by stagflation in the 1970s, which discredited the theory. The second declaration was in the early 2000s, following the stability and growth in the 1980s and 1990s in what came to be known as The Great Moderation. Notably, in 2003, Robert Lucas, in his presidential address to the American Economic Association, declared that the "central problem of depression-prevention [has] been solved, for all practical purposes." [21] Unfortunately, this was followed by the 2008–2012 global recession.

Various regions have experienced prolonged depressions, most dramatically the economic crisis in former Eastern Bloc countries following the end of the Soviet Union in 1991. For several of these countries the period 1989–2010 has been an ongoing depression, with real income still lower than in 1989. [22] This has been attributed not to a cyclical pattern, but to a mismanaged transition from command economies to market economies [ by whom? ].

In 1946, economists Arthur F. Burns and Wesley C. Mitchell provided the now standard definition of business cycles in their book Measuring Business Cycles: [23]

Business cycles are a type of fluctuation found in the aggregate economic activity of nations that organize their work mainly in business enterprises: a cycle consists of expansions occurring at about the same time in many economic activities, followed by similarly general recessions, contractions, and revivals which merge into the expansion phase of the next cycle; in duration, business cycles vary from more than one year to ten or twelve years; they are not divisible into shorter cycles of similar characteristics with amplitudes approximating their own.

According to A. F. Burns: [24]

Business cycles are not merely fluctuations in aggregate economic activity. The critical feature that distinguishes them from the commercial convulsions of earlier centuries or from the seasonal and other short term variations of our own age is that the fluctuations are widely diffused over the economy – its industry, its commercial dealings, and its tangles of finance. The economy of the western world is a system of closely interrelated parts. He who would understand business cycles must master the workings of an economic system organized largely in a network of free enterprises searching for profit. The problem of how business cycles come about is therefore inseparable from the problem of how a capitalist economy functions.

In the United States, it is generally accepted that the National Bureau of Economic Research (NBER) is the final arbiter of the dates of the peaks and troughs of the business cycle. An expansion is the period from a trough to a peak and a recession as the period from a peak to a trough. The NBER identifies a recession as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production". [25]

Upper turning points of business cycle, commodity prices and freight rates

There is often a close timing relationship between the upper turning points of the business cycle, commodity prices, and freight rates, which is shown to be particularly tight in the grand peak years of 1873, 1889, 1900 and 1912. [26] Hamilton expressed that in the post war era, a majority of recessions are connected to an increase in oil price. [27]

Commodity price shocks are considered to be a significant driving force of the US business cycle. [28]

Indicators

Economic indicators are used to measure the business cycle: consumer confidence index, retail trade index, unemployment and industry/service production index [ disambiguation needed ]. Stock and Watson claim that financial indicators’ predictive ability is not stable over different time periods because of economic shocks, random fluctuations and development in financial systems. [29] Ludvigson believes consumer confidence index is a coincident indicator as it relates to consumer’s current situations. [30] Winton & Ralph state that retail trade index is a benchmark for the current economic level because its aggregate value counts up for two-thirds of the overall GDP and reflects the real state of the economy. [31] According to Stock & Watson, unemployment claim can predict when the business cycle is entering a downward phase. [32] Banbura and Rüstler argue that industry production’s GDP information can be delayed as it measures real activity with real number, but it provides an accurate prediction of GDP. [33]

Series used to infer the underlying business cycle fall into three categories: lagging, coincident, and leading. They are described as main elements of an analytic system to forecast peaks and troughs in the business cycle. [34] For almost 30 years, these economic data series are considered as "the leading index" or "the leading indicators"-were compiled and published by the U.S. Department of Commerce.

A prominent coincident, or real-time, business cycle indicator is the Aruoba-Diebold-Scotti Index.

Spectral analysis of business cycles

Recent research employing spectral analysis has confirmed the presence of Kondratiev waves in the world GDP dynamics at an acceptable level of statistical significance. [35] Korotayev & Tsirel also detected shorter business cycles, dating the Kuznets to about 17 years and calling it the third sub-harmonic of the Kondratiev, meaning that there are three Kuznets cycles per Kondratiev.[ jargon ]

Recurrence quantification analysis

Recurrence quantification analysis has been employed to detect the characteristic of business cycles and economic development. To this end, Orlando et al. [36] developed the so-called recurrence quantification correlation index to test correlations of RQA on a sample signal and then investigated the application to business time series. The said index has been proven to detect hidden changes in time series. Further, Orlando et al., [37] over an extensive dataset, shown that recurrence quantification analysis may help in anticipating transitions from laminar (i.e. regular) to turbulent (i.e. chaotic) phases such as USA GDP in 1949, 1953, etc. Last but not least, it has been demonstrated that recurrence quantification analysis can detect differences between macroeconomic variables and highlight hidden features of economic dynamics. [38]

Cycles or fluctuations?

The Business Cycle follows changes in stock prices which are mostly caused by external factors such as socioeconomic conditions, inflation, exchange rates. Intellectual capital does not affect a company stock's current earnings. Intellectual capital contributes to a stock's return growth. [39]

In recent years economic theory has moved towards the study of economic fluctuation rather than a "business cycle" [40] – though some economists use the phrase 'business cycle' as a convenient shorthand. For example, Milton Friedman said that calling the business cycle a "cycle" is a misnomer, because of its non-cyclical nature. Friedman believed that for the most part, excluding very large supply shocks, business declines are more of a monetary phenomenon. [41] Arthur F. Burns and Wesley C. Mitchell define business cycle as a form of fluctuation. In economic activities, a cycle of expansions happening, followed by recessions, contractions, and revivals. All of which combine to form the next cycle's expansion phase; this sequence of change is repeated but not periodic. [42]

Proposed explanations

The explanation of fluctuations in aggregate economic activity is one of the primary concerns of macroeconomics and a variety of theories have been proposed to explain them.

Exogenous vs. endogenous

Within economics, it has been debated as to whether or not the fluctuations of a business cycle are attributable to external (exogenous) versus internal (endogenous) causes. In the first case shocks are stochastic, in the second case shocks are deterministically chaotic and embedded in the economic system. [43] The classical school (now neo-classical) argues for exogenous causes and the underconsumptionist (now Keynesian) school argues for endogenous causes. These may also broadly be classed as "supply-side" and "demand-side" explanations: supply-side explanations may be styled, following Say's law, as arguing that "supply creates its own demand", while demand-side explanations argue that effective demand may fall short of supply, yielding a recession or depression.

This debate has important policy consequences: proponents of exogenous causes of crises such as neoclassicals largely argue for minimal government policy or regulation (laissez faire), as absent these external shocks, the market functions, while proponents of endogenous causes of crises such as Keynesians largely argue for larger government policy and regulation, as absent regulation, the market will move from crisis to crisis. This division is not absolute – some classicals (including Say) argued for government policy to mitigate the damage of economic cycles, despite believing in external causes, while Austrian School economists argue against government involvement as only worsening crises, despite believing in internal causes.

The view of the economic cycle as caused exogenously dates to Say's law, and much debate on endogeneity or exogeneity of causes of the economic cycle is framed in terms of refuting or supporting Say's law; this is also referred to as the "general glut" (supply in relation to demand) debate.

Until the Keynesian revolution in mainstream economics in the wake of the Great Depression, classical and neoclassical explanations (exogenous causes) were the mainstream explanation of economic cycles; following the Keynesian revolution, neoclassical macroeconomics was largely rejected. There has been some resurgence of neoclassical approaches in the form of real business cycle (RBC) theory. The debate between Keynesians and neo-classical advocates was reawakened following the recession of 2007.

Mainstream economists working in the neoclassical tradition, as opposed to the Keynesian tradition, have usually viewed the departures of the harmonic working of the market economy as due to exogenous influences, such as the State or its regulations, labor unions, business monopolies, or shocks due to technology or natural causes.

Contrarily, in the heterodox tradition of Jean Charles Léonard de Sismondi, Clément Juglar, and Marx the recurrent upturns and downturns of the market system are an endogenous characteristic of it. [44]

The 19th-century school of under consumptionism also posited endogenous causes for the business cycle, notably the paradox of thrift, and today this previously heterodox school has entered the mainstream in the form of Keynesian economics via the Keynesian revolution.

Mainstream economics

Mainstream economics views business cycles as essentially "the random summation of random causes". In 1927, Eugen Slutzky observed that summing random numbers, such as the last digits of the Russian state lottery, could generate patterns akin to that we see in business cycles, an observation that has since been repeated many times. This caused economists to move away from viewing business cycles as a cycle that needed to be explained and instead viewing their apparently cyclical nature as a methodological artefact. This means that what appear to be cyclical phenomena can actually be explained as just random events that are fed into a simple linear model. Thus business cycles are essentially random shocks that average out over time. Mainstream economists have built models of business cycles based the idea that they are caused by random shocks. [45] [46] [47] Due to this inherent randomness, recessions can sometimes not occur for decades; for example, Australia did not experience any recession between 1991 and 2020. [48]

While economists have found it difficult to forecast recessions or determine their likely severity, research indicates that longer expansions do not cause following recessions to be more severe. [49]

Keynesian

According to Keynesian economics, fluctuations in aggregate demand cause the economy to come to short run equilibrium at levels that are different from the full employment rate of output. These fluctuations express themselves as the observed business cycles. Keynesian models do not necessarily imply periodic business cycles. However, simple Keynesian models involving the interaction of the Keynesian multiplier and accelerator give rise to cyclical responses to initial shocks. Paul Samuelson's "oscillator model" [50] is supposed to account for business cycles thanks to the multiplier and the accelerator. The amplitude of the variations in economic output depends on the level of the investment, for investment determines the level of aggregate output (multiplier), and is determined by aggregate demand (accelerator).

In the Keynesian tradition, Richard Goodwin [51] accounts for cycles in output by the distribution of income between business profits and workers' wages. The fluctuations in wages are almost the same as in the level of employment (wage cycle lags one period behind the employment cycle), for when the economy is at high employment, workers are able to demand rises in wages, whereas in periods of high unemployment, wages tend to fall. According to Goodwin, when unemployment and business profits rise, the output rises.

Cyclical behavior of exports and imports

Exports and imports are large components of an economy’s aggregate expenditure, especially one that is oriented toward international trade. Income is an essential determinant of the level of imported goods. A higher GDP reflects a higher level of spending on imported goods and services, and vice versa. Therefore, expenditure on imported goods and services fall during a recession and rise during an economic expansion or boom. [52]

Import expenditures are commonly considered to be procyclical and cyclical in nature, coincident with the business cycle. [53] Domestic export expenditures give a good indication of foreign business cycles as foreign import expenditures are coincident with the foreign business cycle.

Credit/debt cycle

One alternative theory is that the primary cause of economic cycles is due to the credit cycle: the net expansion of credit (increase in private credit, equivalently debt, as a percentage of GDP) yields economic expansions, while the net contraction causes recessions, and if it persists, depressions. In particular, the bursting of speculative bubbles is seen as the proximate cause of depressions, and this theory places finance and banks at the center of the business cycle.

A primary theory in this vein is the debt deflation theory of Irving Fisher, which he proposed to explain the Great Depression. A more recent complementary theory is the Financial Instability Hypothesis of Hyman Minsky, and the credit theory of economic cycles is often associated with Post-Keynesian economics such as Steve Keen.

Post-Keynesian economist Hyman Minsky has proposed an explanation of cycles founded on fluctuations in credit, interest rates and financial frailty, called the Financial Instability Hypothesis. In an expansion period, interest rates are low and companies easily borrow money from banks to invest. Banks are not reluctant to grant them loans, because expanding economic activity allows business increasing cash flows and therefore they will be able to easily pay back the loans. This process leads to firms becoming excessively indebted, so that they stop investing, and the economy goes into recession.

While credit causes have not been a primary theory of the economic cycle within the mainstream, they have gained occasional mention, such as ( Eckstein & Sinai 1986 ), cited approvingly by ( Summers 1986 ).

Real business-cycle theory

Within mainstream economics, Keynesian views have been challenged by real business cycle models in which fluctuations are due to random changes in the total productivity factor (which are caused by changes in technology as well as the legal and regulatory environment). This theory is most associated with Finn E. Kydland and Edward C. Prescott, and more generally the Chicago school of economics (freshwater economics). They consider that economic crisis and fluctuations cannot stem from a monetary shock, only from an external shock, such as an innovation. [54]

Product based theory of economic cycles

International product life cycle Product based theory of economic cycles.png
International product life cycle

This theory explains the nature and causes of economic cycles from the viewpoint of life-cycle of marketable goods. [55] The theory originates from the work of Raymond Vernon, who described the development of international trade in terms of product life-cycle – a period of time during which the product circulates in the market. Vernon stated that some countries specialize in the production and export of technologically new products, while others specialize in the production of already known products. The most developed countries are able to invest large amounts of money in the technological innovations and produce new products, thus obtaining a dynamic comparative advantage over developing countries.

Recent research by Georgiy Revyakin proved initial Vernon theory and showed economic cycles in developed countries overran economic cycles in developing countries. [56] He also presumed economic cycles with different periodicity can be compared to the products with various life-cycles. In case of Kondratiev waves such products correlate with fundamental discoveries implemented in production (inventions which form the technological paradigm: Richard Arkwright's machines, steam engines, industrial use of electricity, computer invention, etc.); Kuznets cycles describe such products as infrastructural components (roadways, transport, utilities, etc.); Juglar cycles may go in parallel with enterprise fixed capital (equipment, machinery, etc.), and Kitchin cycles are characterized by change in the society preferences (tastes) for consumer goods, and time, which is necessary to start the production.

Highly competitive market conditions would determine simultaneous technological updates of all economic agents (as a result, cycle formation): in case if a manufacturing technology at an enterprise does not meet the current technological environment, – such company loses its competitiveness and eventually goes bankrupt.

Political business cycle

Another set of models tries to derive the business cycle from political decisions. The political business cycle theory is strongly linked to the name of Michał Kalecki who discussed "the reluctance of the 'captains of industry' to accept government intervention in the matter of employment". [57] Persistent full employment would mean increasing workers' bargaining power to raise wages and to avoid doing unpaid labor, potentially hurting profitability. However, he did not see this theory as applying under fascism, which would use direct force to destroy labor's power.

In recent years, proponents of the "electoral business cycle" theory have argued that incumbent politicians encourage prosperity before elections in order to ensure re-election – and make the citizens pay for it with recessions afterwards. [58] The political business cycle is an alternative theory stating that when an administration of any hue is elected, it initially adopts a contractionary policy to reduce inflation and gain a reputation for economic competence. It then adopts an expansionary policy in the lead up to the next election, hoping to achieve simultaneously low inflation and unemployment on election day. [59]

The partisan business cycle suggests that cycles result from the successive elections of administrations with different policy regimes. Regime A adopts expansionary policies, resulting in growth and inflation, but is voted out of office when inflation becomes unacceptably high. The replacement, Regime B, adopts contractionary policies reducing inflation and growth, and the downwards swing of the cycle. It is voted out of office when unemployment is too high, being replaced by Party A.

Marxian economics

For Marx, the economy based on production of commodities to be sold in the market is intrinsically prone to crisis. In the heterodox Marxian view, profit is the major engine of the market economy, but business (capital) profitability has a tendency to fall that recurrently creates crises in which mass unemployment occurs, businesses fail, remaining capital is centralized and concentrated and profitability is recovered. In the long run, these crises tend to be more severe and the system will eventually fail. [60]

Some Marxist authors such as Rosa Luxemburg viewed the lack of purchasing power of workers as a cause of a tendency of supply to be larger than demand, creating crisis, in a model that has similarities with the Keynesian one. Indeed, a number of modern authors have tried to combine Marx's and Keynes's views. Henryk Grossman [61] reviewed the debates and the counteracting tendencies and Paul Mattick subsequently emphasized the basic differences between the Marxian and the Keynesian perspective. While Keynes saw capitalism as a system worth maintaining and susceptible to efficient regulation, Marx viewed capitalism as a historically doomed system that cannot be put under societal control. [62]

The American mathematician and economist Richard M. Goodwin formalised a Marxist model of business cycles known as the Goodwin Model in which recession was caused by increased bargaining power of workers (a result of high employment in boom periods) pushing up the wage share of national income, suppressing profits and leading to a breakdown in capital accumulation. Later theorists applying variants of the Goodwin model have identified both short and long period profit-led growth and distribution cycles in the United States and elsewhere. [63] [64] [65] [66] [67] David Gordon provided a Marxist model of long period institutional growth cycles in an attempt to explain the Kondratiev wave. This cycle is due to the periodic breakdown of the social structure of accumulation, a set of institutions which secure and stabilize capital accumulation.

Austrian School

Economists of the heterodox Austrian School argue that business cycles are caused by excessive issuance of credit by banks in fractional reserve banking systems. According to Austrian economists, excessive issuance of bank credit may be exacerbated if central bank monetary policy sets interest rates too low, and the resulting expansion of the money supply causes a "boom" in which resources are misallocated or "malinvested" because of artificially low interest rates. Eventually, the boom cannot be sustained and is followed by a "bust" in which the malinvestments are liquidated (sold for less than their original cost) and the money supply contracts. [68] [69]

One of the criticisms of the Austrian business cycle theory is based on the observation that the United States suffered recurrent economic crises in the 19th century, notably the Panic of 1873, which occurred prior to the establishment of a U.S. central bank in 1913. Adherents of the Austrian School, such as the historian Thomas Woods, argue that these earlier financial crises were prompted by government and bankers' efforts to expand credit despite restraints imposed by the prevailing gold standard, and are thus consistent with Austrian Business Cycle Theory. [70] [71]

The Austrian explanation of the business cycle differs significantly from the mainstream understanding of business cycles and is generally rejected by mainstream economists. Mainstream economists generally do not support Austrian school explanations for business cycles, on both theoretical as well as real-world empirical grounds. [72] [73] [74] [75] [76] [77] Austrians claim that the boom-and-bust business cycle is caused by government intervention into the economy, and that the cycle would be comparatively rare and mild without central government interference.

Yield curve

The slope of the yield curve is one of the most powerful predictors of future economic growth, inflation, and recessions. [78] One measure of the yield curve slope (i.e. the difference between 10-year Treasury bond rate and the 3-month Treasury bond rate) is included in the Financial Stress Index published by the St. Louis Fed. [79] A different measure of the slope (i.e. the difference between 10-year Treasury bond rates and the federal funds rate) is incorporated into the Index of Leading Economic Indicators published by The Conference Board. [80]

An inverted yield curve is often a harbinger of recession. A positively sloped yield curve is often a harbinger of inflationary growth. Work by Arturo Estrella and Tobias Adrian has established the predictive power of an inverted yield curve to signal a recession. Their models show that when the difference between short-term interest rates (they use 3-month T-bills) and long-term interest rates (10-year Treasury bonds) at the end of a federal reserve tightening cycle is negative or less than 93 basis points positive that a rise in unemployment usually occurs. [81] The New York Fed publishes a monthly recession probability prediction derived from the yield curve and based on Estrella's work.

All the recessions in the United States since 1970 (up through 2017) have been preceded by an inverted yield curve (10-year vs. 3-month). Over the same time frame, every occurrence of an inverted yield curve has been followed by recession as declared by the NBER business cycle dating committee. [82]

Estrella and others have postulated that the yield curve affects the business cycle via the balance sheet of banks (or bank-like financial institutions). [83] When the yield curve is inverted banks are often caught paying more on short-term deposits (or other forms of short-term wholesale funding) than they are making on long-term loans leading to a loss of profitability and reluctance to lend resulting in a credit crunch. When the yield curve is upward sloping, banks can profitably take-in short term deposits and make long-term loans so they are eager to supply credit to borrowers. This eventually leads to a credit bubble.

Georgism

Henry George claimed land price fluctuations were the primary cause of most business cycles. [84] The theory is generally discounted by modern mainstream economists. [85]

Mitigating an economic downturn

Many social indicators, such as mental health, crimes, and suicides, worsen during economic recessions (though general mortality tends to fall, and it is in expansions when it tends to increase). [86] As periods of economic stagnation are painful for the many who lose their jobs, there is often political pressure for governments to mitigate recessions. Since the 1940s, following the Keynesian revolution, most governments of developed nations have seen the mitigation of the business cycle as part of the responsibility of government, under the rubric of stabilization policy.

Since in the Keynesian view, recessions are caused by inadequate aggregate demand, when a recession occurs the government should increase the amount of aggregate demand and bring the economy back into equilibrium. This the government can do in two ways, firstly by increasing the money supply (expansionary monetary policy) and secondly by increasing government spending or cutting taxes (expansionary fiscal policy).

By contrast, some economists, notably New classical economist Robert Lucas, argue that the welfare cost of business cycles are very small to negligible, and that governments should focus on long-term growth instead of stabilization.

However, even according to Keynesian theory, managing economic policy to smooth out the cycle is a difficult task in a society with a complex economy. Some theorists, notably those who believe in Marxian economics, believe that this difficulty is insurmountable. Karl Marx claimed that recurrent business cycle crises were an inevitable result of the operations of the capitalistic system. In this view, all that the government can do is to change the timing of economic crises. The crisis could also show up in a different form, for example as severe inflation or a steadily increasing government deficit. Worse, by delaying a crisis, government policy is seen as making it more dramatic and thus more painful.

Additionally, since the 1960s neoclassical economists have played down the ability of Keynesian policies to manage an economy. Since the 1960s, economists like Nobel Laureates Milton Friedman and Edmund Phelps have made ground in their arguments that inflationary expectations negate the Phillips curve in the long run. The stagflation of the 1970s provided striking support for their theories while proving a dilemma for Keynesian policies, which appeared to necessitate both expansionary policies to mitigate recession and contractionary policies to reduce inflation. Friedman has gone so far as to argue that all the central bank of a country should do is to avoid making large mistakes, as he believes they did by contracting the money supply very rapidly in the face of the Wall Street Crash of 1929, in which they made what would have been a recession into the Great Depression.[ citation needed ]

In economics, Kondratiev waves are hypothesized cycle-like phenomena in the modern world economy. The phenomenon is closely connected with the technology life cycle.

Keynesian economics Group of macroeconomic theories

Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. Instead, it is influenced by a host of factors – sometimes behaving erratically – affecting production, employment, and inflation.

Macroeconomics Study of an economy as a whole

Macroeconomics is a branch of economics dealing with performance, structure, behavior, and decision-making of an economy as a whole. For example, using interest rates, taxes, and government spending to regulate an economy’s growth and stability. This includes regional, national, and global economies. According to a 2018 assessment by economists Emi Nakamura and Jón Steinsson, economic "evidence regarding the consequences of different macroeconomic policies is still highly imperfect and open to serious criticism."

Recession Business cycle contraction; general slowdown on economic activity

In economics, a recession is a business cycle contraction when there is a general decline in economic activity. Recessions generally occur when there is a widespread drop in spending. This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock, the bursting of an economic bubble, or a large-scale anthropogenic or natural disaster. In the United States, it is defined as "a significant decline in economic activity spread across the market, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales". In the United Kingdom, it is defined as a negative economic growth for two consecutive quarters.

Stagflation Both high inflation and high unemployment

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.

Monetarism School of thought in monetary economics

Monetarism is a school of thought in monetary economics that emphasizes the role of governments in controlling the amount of money in circulation. Monetarist theory asserts that variations in the money supply have major influences on national output in the short run and on price levels over longer periods. Monetarists assert that the objectives of monetary policy are best met by targeting the growth rate of the money supply rather than by engaging in discretionary monetary policy.

Fiscal policy Use of government revenue collection and expenditure to influence a countrys economy

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 revenues and expenditures to influence macroeconomic variables developed as a result of the Great Depression, when the previous laissez-faire approach to economic management became unpopular. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorized that government changes in the levels of taxation and government spending influences 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 stabilize the economy over the course of the business cycle.

Nicholas Kaldor Hungarian-British economist

Nicholas Kaldor, Baron Kaldor, born Káldor Miklós, was a Cambridge economist in the post-war period. He developed the "compensation" criteria called Kaldor–Hicks efficiency for welfare comparisons (1939), derived the cobweb model, and argued for certain regularities observable in economic growth, which are called Kaldor's growth laws. Kaldor worked alongside Gunnar Myrdal to develop the key concept Circular Cumulative Causation, a multicausal approach where the core variables and their linkages are delineated. Both Myrdal and Kaldor examine circular relationships, where the interdependencies between factors are relatively strong, and where variables interlink in the determination of major processes. Gunnar Myrdal got the concept from Knut Wicksell and developed it alongside Nicholas Kaldor when they worked together at the United Nations Economic Commission for Europe. Myrdal concentrated on the social provisioning aspect of development, while Kaldor concentrated on demand-supply relationships to the manufacturing sector. Kaldor also coined the term "convenience yield" related to commodity markets and the so-called theory of storage, which was initially developed by Holbrook Working.

The Austrian business cycle theory (ABCT) is an economic theory developed by the Austrian School of economics about how business cycles occur. The theory views business cycles as the consequence of excessive growth in bank credit due to artificially low interest rates set by a central bank or fractional reserve banks. The Austrian business cycle theory originated in the work of Austrian School economists Ludwig von Mises and Friedrich Hayek. Hayek won the Nobel Prize in Economics in 1974 in part for his work on this theory.

Procyclical and countercyclical variables are variables that fluctuate in a way that is positively or negatively correlated with business cycle fluctuations in gross domestic product (GDP). The scope of the concept may differ between the context of macroeconomic theory and that of economic policy–making.

Alvin Hansen American economist

Alvin Harvey Hansen was an American economist who taught at the University of Minnesota and was later a chair professor of economics at Harvard University. Often referred to as "the American Keynes", he was a widely read popular author on economic issues, and an influential advisor to the government on economic policy. Hansen helped create the Council of Economic Advisors and the Social Security system. He is best remembered today for introducing Keynesian economics in the United States in the 1930s and 40s.

Economic stability is the absence of excessive fluctuations in the macroeconomy. An economy with fairly constant output growth and low and stable inflation would be considered economically stable. An economy with frequent large recessions, a pronounced business cycle, very high or variable inflation, or frequent financial crises would be considered economically unstable.

Dynamic stochastic general equilibrium modeling is a macroeconomic method which is often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data, as well as future forecasting purposes. DSGE econometric modeling applies general equilibrium theory and microeconomic principles in a tractable manner to postulate economic phenomena, such as economic growth and business cycles, as well as policy effects and market shocks.

New classical macroeconomics School of thought in macroeconomics

New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations.

Saltwater and freshwater economics

In economics, the freshwater school comprises US-based macroeconomists who, in the early 1970s, challenged the prevailing consensus in macroeconomics research. A key element of their approach was the argument that macroeconomics had to be dynamic and based on how individuals and institutions interact in markets and make decisions under uncertainty.

History of macroeconomic thought 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.

New neoclassical synthesis

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 economics. It is an important part of the theoretical foundation for the work done by the Federal Reserve and many other central banks.

Real business-cycle theory macroeconomic model

Real business-cycle theory is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real shocks. Unlike other leading theories of the business cycle, RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment. That is, the level of national output necessarily maximizes expected utility, and governments should therefore concentrate on long-run structural policy changes and not intervene through discretionary fiscal or monetary policy designed to actively smooth out economic short-term fluctuations.

Marxism and Keynesianism is a method of understanding and comparing the works of influential economists John Maynard Keynes and Karl Marx. Both men's works has fostered respective schools of economic thought that have had significant influence in various academic circles as well as in influencing government policy of various states. Keynes' work found popularity in developed liberal economies following the Great Depression and World War II, most notably Franklin D. Roosevelt's New Deal in the United States in which strong industrial production was backed by strong unions and government support. Marx's work, with varying degrees of faithfulness, led the way to a number of socialist states, notably the Soviet Union and the People's Republic of China. The immense influence of both Marxian and Keynesian schools has led to numerous comparisons of the work of both economists along with synthesis of both schools.
