Abstract
This paper offers a systematic comparison of a wide range of
leaning-against-the-wind interest-rate policy rules within a
macroeconomic, stock-flow consistent, agent-based model. The model
generates endogenous booms and busts along credit cycles. As feed back
loops on aggregate demand affect the goods and the labor markets, the
real and the financial sides of the economy are closely interconnected.
The baseline scenario is able to qualitatively reproduce a wide range of
stylized facts. We show that a monetary policy rule that targets the
movements in the net worth of firms significantly dampens the credit
cycles and reduces the employment costs of financial crises, because
this indicator incorporates early signals of financial imbalances.
Performances of this three-mandate Taylor rule are also more robust to
the specific parameter values and regulatory framework than the standard
dual-mandate Taylor rules. Nonetheless, none of the policy rules under
study completely eliminates the high employment costs of financial
crises. (C) 2018 Elsevier B.V. All rights reserved.
