Consumption Function Formula with Proportional Income Tax

Consider two hypothetical economies, A and B, that are identical in every way (including having the same marginal propensity to consume), except for their tax systems. Economy A has no income tax, while Economy B has a proportional income tax where a fixed percentage of all income is paid in tax. If total pre-tax income increases by $100 million in both economies, how will the resulting change in total consumption spending compare between them?

Impact of Proportional Tax on Household Spending

In a macroeconomic model where consumption depends on after-tax income, the introduction of a proportional income tax directly lowers the value of the marginal propensity to consume.

In an economy, the government introduces a proportional income tax. How does this tax affect the aggregate consumption function when plotted with total consumption on the vertical axis and total pre-tax income on the horizontal axis? Assume the amount people choose to spend out of any extra after-tax income remains unchanged.

In a macroeconomic model where household spending is influenced by a proportional income tax, match each term to its correct description.

Impact of Proportional Taxes on Consumption Sensitivity

In a macroeconomic model with a proportional income tax, an increase in total income leads to a smaller increase in consumption spending than it would in an economy without taxes. This is because the tax reduces the household's __________, which is the basis for its spending decisions.
