Which of the following is an example of an exogenous (external) cause of business cycles rather than an endogenous one?

A sudden global oil price spike caused by war is an exogenous cause, because it originates outside the economy's own working. Inventory changes, multiplier-accelerator interaction and credit expansion arise from within the economic system and are therefore treated as endogenous causes of business cycles.

  1. AFluctuation in inventories driven by firms' sales expectations
  2. BA sudden global spike in crude oil prices due to war affecting Indian production costsCorrect
  3. CInteraction of the multiplier and the accelerator
  4. DChanges in bank credit created by the banking system's own lending behaviour

Explanation

Exogenous causes originate outside the economic system, such as wars, oil shocks, weather or policy shocks. A global oil price spike due to war fits this. Inventory swings, multiplier-accelerator interaction and credit expansion arise from within the economy, so they are endogenous.
