What is a 'Boom And Bust Cycle'
A boom and bust cycle is a process of economic expansion and contraction that occurs repeatedly. The boom and bust cycle is a key characteristic of today’s capitalist economies. During the boom the economy grows, jobs are plentiful and the market brings high returns to investors. In the subsequent bust the economy shrinks, people lose their jobs and investors lose money. Boom-bust cycles last for varying lengths of time; they also vary in severity.
BREAKING DOWN 'Boom And Bust Cycle'
Since the mid-1940s, the United States has experienced 12 boom-bust cycles. Why do we have a boom and bust cycle instead of a long, steady economic growth period? The answer can be found in the way central banks handle the money supply.
During a boom, the central bank makes it easier to obtain credit by lending money at low interest rates. Individuals and businesses can then borrow money easily and cheaply and invest it in, say, technology stocks or houses. Many people earn high returns on their investments, and the economy grows.
The problem is that when credit is too easy to obtain and interest rates are too low, people will overinvest. This excess investment is called “malinvestment”. There won’t be enough demand for, say, all the homes that have been built, and the bust cycle will set in. Things that have been overinvested in will decline in value. Investors lose money, consumers cut spending and companies cut jobs. Credit becomes more difficult to obtain as boom-time borrowers become unable to make their loan payments. The bust periods are referred to as recessions; if the recession is particularly severe, it is called a depression.
Government subsidies that make it less expensive to invest also contribute to the boom-bust cycle by encouraging companies and individuals to overinvest in the subsidized item. For example, the mortgage interest tax deduction subsidizes a home purchase by making the mortgage interest less expensive. The subsidy encourages more people to buy homes.
