Whcih is an exogenous factor that affects the business cycle?

Natural Disasters.

Explanation:

The business cycle refers to fluctuations in the economic activity of a country or a company in relation to factors that stimulate or discourage the positive economic balance. These factors may be endogenous in nature (determining factors that are inherent in the economic entity in question) or exogenous in nature (determining factors that relate to the environment.)

One exogenous factor that affects the business cycle is natural disasters.

Calculating the long-term impact caused by natural disasters is an inaccurate science. Multiple factors affect the size of the initial losses as well as the resilience of that region after the tragedy. In general, sites hit by natural disasters experience a phase of acute loss, followed by a recovery phase that may be more or less rapid and more or less complete, and in some cases may cause the economy of that place to end. Getting better or worse than it was before the tragedy, that is, natural disasters can cause economic fluctuations in a region, affecting the business cycle.
