The business cycle or economic cycle refers to the periodic fluctuations of economic activity about its long term growth trend. The cycle involves shifts over time between periods of relatively rapid growth of output (recovery and prosperity), alternating with periods of relative stagnation or decline (contraction or recession). These fluctuations are often measured using the real gross domestic product. One of the government's main roles is to smooth out the business cycle and reduce its fluctuations.
To call those alternances "cycles" is rather misleading as they don't tend to repeat at fairly regular time intervals. Most observers find that their lengths (from peak to peak, or from trough to trough) vary, so that cycles are not mechanical in their regularity. Since no two cycles are alike in their details, some economists dispute the existence of cycles and use the word "fluctuations" (or the like) instead. Others see enough similarities between cycles that the cycle is a valid basis of studying the state of the economy. A key question is whether or not there are similar mechanisms that generate recessions and/or booms that exist in capitalist economies so that the dynamics that appear as a cycle will be seen again and again.
n the Juglar cycle, which is sometimes called "the" business cycle, recovery and prosperity are associated with increases in productivity, consumer confidence, aggregate demand, and prices. In the cycles before World War II or that of the late 1990s in the United States, the growth periods usually ended with the failure of speculative investments built on a bubble of confidence that bursts or deflates. In these cycles, the periods of contraction and stagnation reflect a purging of unsuccessful enterprises as resources are transferred by market forces from less productive uses to more productive uses. Cycles between 1945 and the 1990s in the United States were generally more restrained and followed political factors, such as fiscal policy and monetary policy. Automatic stabilisation due the government's budget helped defeat the cycle even without conscious action by policy-makers.
Firstly, productive capital used by firms will be worn out over time and require replacements. Spending on capital equipment such as machinery is necessary, which increases aggregate expenditure (AE) and causes the economy to slowly climb. Secondly, the low prices characteristic of a trough phase will cause increased demand for them, resulting in inflation which is characteristic of the boom phase. The low interest rates will stimulate increased borrowing. The repayments and interest which need to be paid back will contribute to the rise in AE. Governments also aim to improve the business cycle so as to provide stability, get re-elected and to ease worries about the state of the economy. They also do this to attract foreign investors and improve their international reputation.
Michal Kalecki's Marxian-influenced "political business cycle" theory blames the government: he argued that no democratic government under capitalism would allow the persistence of full employment, so that recessions would be caused by political decisions: persistent full employment would mean increasing workers' bargaining power to raise wages and to avoid doing unpaid labor, potentially hurting profitability. (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.
The Austrian School of economics rejects the suggestion that the business cycle is an inherent feature of an unregulated economy and argues that it is caused by intervention in the money supply. Austrian School economists, following Ludwig von Mises, point to the role of the interest rate as the price of investment capital, guiding investment decisions. In an unregulated (free-market) economy, it is posited that the interest rate reflects the actual time preference of lenders and borrowers. Some follow Knut Wicksell to call this the "natural" interest rate.[1] Government control of the money supply through central banks disturbs this equilibrium such that the interest rate no longer reflects the real supply of and demand for investment capital. Austrian School economists conclude that, if the interest rate is artificially low, then the demand for loans will be higher than the actual supply of willing lenders, and if the interest rate is artificially high, the opposite situation will occur. This misinformation leads investors to misallocate capital, borrowing and investing either too much or too little in long-term projects. Periodic recessions, then, are seen as necessary "corrections" following periods of fiat credit expansion, when unprofitable investments are liquidated, freeing capital for new investment.
The Austrian theory also predicts that the imposition of artificially low interest rates, and the resulting increase in the supply of fiat credit, generates inflation, which obliges the central bank to increase the supply of credit yet further to maintain the artificially low interest rate, thus prolonging the "boom" and worsening the inevitable "correction." Austrian School economists point to the dot-com investment frenzy as a modern example of artificially abundant credit subsidizing unsustainable overinvestment.
In the Keynesian view, this Austrian theory assumes that the "natural" rate of interest is unique at any given time and cannot be affected by policy. To Keynesian economists, this rate is only unique if the economy is assumed to always be at full employment. If the economy is operating with less than full employment, i.e., with high unemployment above the NAIRU, then in theory monetary policy and fiscal policy can have a positive role to play rather than simply creating booms that necessarily collapse on themselves. It should be noted that, in the Austrian School, the absence of full employment is typically attributed to government interference in the labour markets, such as minimum wage laws, employment regulations, and taxes levied against employers, which prevent the employment market from fully clearing.
