Keynesian models do not necessarily indicate periodic business cycles but imply cyclical responses to shocks via multipliers. real shocks directly affect only the IS curve or the FE line, but not the LM curve. What do you think such shocks might be? Les périodes de croissance économique et de récession économique ne sont alors que des réponses de l'économie à des chocs exogènes. Hawtrey, the main supporter of this theory, advocated that business cycles are the continuous phases of inflation and deflation. Examples of such shocks … Business cycles could be caused by the cumulation of small productivity shocks. This explains why investment spending is more volatile than consumption.

Instead, he may consume some but invest the rest in capital to enhance production in subsequent periods and thus increase future consumption. In general, early theorists believed monetary factors could not affect real factors such as real output. The HP filter identifies the longer term fluctuations as part of the growth trend while classifying the more jumpy fluctuations as part of the cyclical component. Consider an individual of a given age who is in the labour force, has a life expectancy of T years, and plans to remain in the labour force for N years.
