投資の循環的挙動

Investment mainly refers to spending by private businesses on new capital goods, such as machines and the construction of factories.

Investment is typically procyclical, meaning that it usually rises during expansions and falls during contractions.

Also, investment is coincident with the business cycle, which means that its peaks and troughs happen around the same time as the peaks and troughs of the business cycle.

Businesses invest in capital goods when they expect an increase in demand for their products.

During an expansion, firms expect higher sales, so they invest in new capital goods.

For example, automobile companies might build new factories during an expansion.

On the other hand, during a contraction, firms expect lower sales, so they often delay investment in new capital goods.

For example, construction companies may delay buying heavy machinery during a recession.

So, investment moves closely with the business cycle, rising during periods of economic expansion when businesses are optimistic and falling during contractions when firms become more cautious about future demand.
