_________________________ is after tax personal income.

Disposable income is defined as the amount of money that individuals have available for spending and saving after accounting for taxes. It represents the portion of personal income that consumers can use freely, which can be allocated towards essentials such as housing and food, as well as discretionary expenses like entertainment and luxury items.

Understanding disposable income is crucial in the context of international business because it affects consumer purchasing power and overall economic health in different countries. Countries with higher disposable income levels generally have stronger consumer markets, which can influence foreign investment and business strategy for international firms looking to expand.

The other terms listed do not accurately describe the concept of income left after taxes. Discretionary income refers specifically to the income remaining after necessary expenses are covered, while terms like discharged income and taxed income are not commonly used with the same precise meaning in economic contexts.
