Redistributive Monetary Policy
Liquidity and deflationary spirals self-generate endogenous risk and redistribute wealth. Monetary policy can mitigate these effects and help rebalance wealth after an adverse shock, thereby reducing endogenous risk, stabilizing the economy, and stimulating growth. The redistributive channel differs from the classic Keynesian interest rate channel in models with price stickiness. Central banks assume and redistribute tail risk when purchasing assets or relaxing their collateral requirements. Monetary policy (rules) can be seen as a social insurance scheme for an economy beset by financial frictions. As with any insurance, it carries the cost of moral hazard. Redistributive monetary policy should be strictly limited to undoing the redistribution caused by the amplification effects and by moral hazard considerations.
