Mastering The Market Cycle: Getting the Odds on Your Side

by Howard Marks

The economic theory propounded by John Maynard Keynes in the 1930s dwelled heavily on the role of governments vis-à-vis cycles. Keynesian economics focuses on the role of aggregate demand in determining the level of GDP, in contrast with earlier approaches that emphasized the role of the supply of goods. Keynes said governments should manage the economic cycle by influencing demand. This, in turn, could be accomplished through the use of fiscal tools, including deficits. Keynes urged governments to aid a weak economy by stimulating demand by running deficits. When a government’s outgo—its spending—exceeds its income—primarily from taxes—on balance it puts funds into the economy. This encourages buying and investing. Deficits are stimulative, and thus Keynes considered them helpful in dealing with a weak economy. On the other hand, when economies are strong, Keynes said governments should run surpluses, spending less than they take in. This removes funds from the economy, discouraging spending and investment. Surpluses are contractionary and thus an appropriate response to booms. However, the use of surpluses to cool a thriving economy is little seen these days. No one wants to be a wet blanket when the party is going strong. And spending less than you bring in attracts fewer votes than do generous spending programs. Thus surpluses have become as rare as buggy whips.
