Government spending and interest rates

Most macroeconomic models imply that increases in government spending cause interest rates to rise, but empirical evidence from the U.S. generally fails to support this prediction. We propose a novel explanation for how government spending can have a zero or negative temporary effect on interest rates: the increased demand for credit associated with government spending is offset by an increase in the supply of credit due to higher aggregate income. We demonstrate this mechanism theoretically and provide evidence consistent with the model's predictions. (c) 2022 Elsevier Ltd. All rights reserved.
