Evaluating a Model's Assumption about Exports

A country's primary trading partner experiences a significant economic boom, leading to increased purchasing power and demand for goods from abroad. Within a basic macroeconomic model that holds the value of exports constant regardless of domestic economic conditions, what is the direct, immediate effect on the value of the country's exports as represented in the model?

In a basic macroeconomic model where total spending is the sum of consumption, investment, government purchases, and net exports, a rapid increase in the country's own national income will directly cause the value of its exports to rise.

Applying the Exogenous Export Assumption

In a simplified macroeconomic model, exports are considered a(n) __________ variable because their value is assumed to be determined by factors outside the model, such as foreign demand, and does not change in response to fluctuations in the domestic economy's income.
