Answer:
income and expenditure both fall
Step-by-step explanation:
GDP can be calculated by 2 approaches; income approach and expenditure approach.
Income approach is the sum of all income in the economy such as wages, salaries, and companies profits, whereas expenditure approach is the sum of all expenditure such as private consumption, consumption in capital goods, the government expenditure and net export. The GDP calculated by these 2 ways are equal. Thus, if an economy's GDP fall, both income and expenditure fall.
