Growth of Real GDP and Business Cycles
Do investors really understand the economy or the business cycle? indices questions whether the markets believe there is a relationship. a; OECD b), there has not till now been a study that investigates this for GDP (see among others NBER`s Business Cycle Dating. There are a couple of ways in which a country's gross domestic product (GDP) and the larger business cycle intersect, but they are most closely.
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"  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 multiplierand is determined by aggregate demand accelerator. In the Keynesian tradition, Richard Goodwin  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 cyclefor 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. Credit cycle and Debt deflation One alternative theory is that the primary cause of economic cycles is due to the credit cycle: 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 Fisherwhich he proposed to explain the Great Depression.
A more recent complementary theory is the Financial Instability Hypothesis of Hyman Minskyand 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. Real business cycle theory[ edit ] Main article: Real Business Cycle theory Within mainstream economics, Keynesian views have been challenged by real business cycle models in which fluctuations are due to technology shocks.
This theory is most associated with Finn E. Kydland and Edward C. Prescottand 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. 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 proves initial Vernon theory and shows that economic cycles in developed countries overrun economic cycles in developing countries. 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.
Simultaneous technological updates by all economic agents as a result, cycle formation would be determined by highly competitive market conditions: Politically based business cycle[ edit ] Another set of models tries to derive the business cycle from political decisions. 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. 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. He did not see this theory as applying under fascismwhich would use direct force to destroy labor's power. In recent years, proponents of the "electoral business cycle" theory[ who? Marxian economics[ edit ] 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.
Indeed, a number of modern authors have tried to combine Marx's and Keynes's views. Henryk Grossman  reviewed the debates and the counteracting tendencies and Paul Mattick subsequently emphasized the basic differences between the Marxian and the Keynesian perspective: 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. This cycle is due to the periodic breakdown of the 'social structure of accumulation' — a set of institutions which secure and stabilise capital accumulation.
Austrian business cycle theory 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. Adherents of the Austrian School, such as the historian Thomas Woodsargue 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.
At time t1 in Figure 5. The point at which an expansion ends and a recession begins is called the peak The point of the business cycle at which an expansion ends and a recession begins.
Real GDP then falls during a period of recession. Eventually it starts upward again at time t2. The point at which a recession ends and an expansion begins is called the trough The point of the business cycle at which a recession ends and an expansion begins.
The expansion continues until another peak is reached at time t3. Some economists prefer to break the expansion phase into two parts. The recovery phase is said to be the period between the previous trough and the time when the economy achieves its previous peak level of real GDP.
A complete business cycle is defined by the passage from one peak to the next. Because the Business Cycle Dating Committee dates peaks and troughs by specific months, and because real GDP is estimated only on a quarterly basis by the Bureau of Economic Analysis, the committee relies on a variety of other indicators that are published monthly, including real personal income, employment, industrial production, and real wholesale and retail sales.
The committee typically determines that a recession has happened long after it has actually begun and sometimes ended! In large part, that avoids problems when data released about the economy are revised, and the committee avoids having to reverse itself on its determination of when a recession begins or ends, something it has never done. In Decemberthe Committee announced that a recession in the United States had begun in December Interestingly, real GDP fell in the fourth quarter ofgrew in the first and second quarters ofand shrank in the third quarter ofso clearly the Committee was not using the two consecutive quarters of declining GDP rule-of-thumb.
Rather, it was taking into account the behavior of a variety of other variables, such as employment and personal income.
Over those years, the economy experienced eight recessions including the current oneshown by the shaded areas in the chart. Although periods of expansion have been more prolonged than periods of recession, we see the cycle of economic activity that characterizes economic life. Recessions—periods of falling real GDP—are shown as shaded areas.
On average, the annual rate of growth of real GDP over the period was 3. Seasonally adjusted at annual rates.
Data for is through 3rd quarter. Real GDP clearly grew between and While the economy experienced expansions and recessions, its general trend during the period was one of rising real GDP. The average annual rate of growth of real GDP was about 3.
During the post—World War II period, the average expansion has lasted 58 months, and the average recession has lasted about 11 months. The recession, which lasted eight months, was thus slightly shorter than the average. The recession lasted 18 months; it was the longest of the post-World War II period. Economists have sought for centuries to explain the forces at work in a business cycle. Not only are the currents that move the economy up or down intellectually fascinating but also an understanding of them is of tremendous practical importance.
A business cycle is not just a movement along a curve in a textbook. It is new jobs for people, or the loss of them. It is new income, or the loss of it. It is the funds to build new schools or to provide better health care—or the lack of funds to do all those things. The story of the business cycle is the story of progress and plenty, of failure and sacrifice.

During the recent recession, the job outlook for college graduates deteriorated. The unemployment rate for college graduates under age 25 rose from 3. The unemployment rate for high school graduates who never enrolled in college went from
