by Howard Marks

Here is what I believe to be the bottom line on economic cycles: The output of an economy is the product of hours worked and output per hour; thus the long-term growth of an economy is determined primarily by fundamental factors like birth rate and the rate of gain in productivity (but also by other changes in society and environment). These factors usually change relatively little from year to year, and only gradually from decade to decade. Thus the average rate of growth is rather steady over long periods of time. Only in the longest of time frames does the secular growth rate of an economy significantly speed up or slow down. But it does. Given the relative stability of underlying secular growth, one might be tempted to expect that the performance of economies would be consistent from year to year. However, a number of factors are subject to variability, causing economic growth — even as it follows the underlying trendline on average — to also exhibit annual variability. These factors can perhaps be viewed as follows: ˚ Endogenous — Annual economic performance can be influenced by variation in decisions made by economic units: for consumers to spend or save, for example, or for businesses to expand or contract, to add to inventories (calling for increased production) or sell from inventories (reducing production relative to what it might otherwise have been). Often these decisions are influenced by the state of mind of economic actors, such as consumers or the manager...
