Abstract:
This study examines how economic inequality influences the effectiveness of fiscal policy using a three-agent New Keynesian DSGE model with incomplete financial markets. The findings suggest that economies with a high share of liquidity-constrained households exhibit larger fiscal multipliers due to their higher marginal propensity to consume. Households respond differently to fiscal stimulus due to variations in their propensity to consume and ability to smooth consumption. Additionally, house prices exhibit a temporary decline in response to fiscal stimulus within the modeled framework. Sensitivity analyses show that factors such as loan-to-value ratios, household composition, and housing preferences significantly alter the fiscal multiplier, emphasizing the need to consider inequality in macroeconomic policy design.
