An individual might choose to consume all of it today. But if he values future consumption, all that extra output might not be worth consuming in its entirety today. Instead, he may consume some but invest the rest in capital to enhance production in subsequent periods and thus increase future consumption. This explains why investment spending is more volatile than consumption. The life-cycle hypothesis argues that households base their consumption decisions on expected lifetime income and so they prefer to “smooth” consumption over time.
Many of the mechanics of running their businesses are opaque, documented poorly in scattered places, and difficult to get a straight answer on from experts. The model is driven by large and sudden changes in available production technology. Crucial to RBC models, “plausible values” for structural variables such as the discount rate, and the rate of capital depreciation are used in the creation of simulated variable paths. These tend to be estimated from econometric studies, with 95% confidence intervals. In fact, simply stated, it is the process of changing the model to fit the data. Since RBC models explain data ex post, it is very difficult to falsify any one model that could be hypothesised to explain the data.
RBC models are highly sample specific, leading some[who? ] to believe that they have little or no predictive power.
That is, above-trend behavior may persist for some time even after the shock disappears. This capital accumulation is often referred to as an internal “propagation mechanism”, since it may increase the persistence of shocks to output. Since productivity is higher, people have more output to consume.
They will thus save in periods of high income and defer consumption of this to periods of low income. Yet another regularity is the co-movement between output and the other macroeconomic variables.
The labor supply curve should therefore be upward sloping. With low wage elasticity of labor (i. e. labor supply curve vertical) most of the shock to productivity would be born by wages and not employment. For RBC theory to work the labor supply curve would therefore have to be almost flat reflecting a high degree of elasticity of labor with respect to real wages.

We can measure this in more detail using correlations as listed in column B of Table 1. Procyclical variables have positive correlations since it usually increases during booms and lowers during recessions. Vice versa, a countercyclical variable affiliates with negative correlations. Acyclical, correlations close to absolutely no, implies no systematic partnership to the business period. This means workers and funds tend to be more productive when the particular economy is experiencing the boom. They may not be quite because productive once the economy will be experiencing a slowdown. Comparable explanations follow for usage and investment, which are usually strongly procyclical.
A string of such productivity shocks will likely result in a boom. Similarly, recessions follow a chain of bad shocks to the economy. If there were no shocks, the economy would just continue following the growth trend with no business cycles. Overall, the basic RBC model predicts that given a temporary shock, output, consumption, investment and labor all rise above their long-term trends and hence formulate into a positive deviation. Furthermore, since more investment means more capital is available for the future, a short-lived shock may have an impact in the future.
