Which price level to target? Strategic delegation in a sticky price and wage economy

摘要

This paper assesses the value of delegating price level targets to a discretionary central bank in an economy with nominal frictions in both labor and product markets. In contrast to recent studies that demonstrate the benefits of targeting the priceof output, model simulations provide evidence that favors targeting the price of labor, or the nominal wage, instead. While both policies impart inertia (a salient feature of commitment), wage targeting dominates output price targeting because the formerdelivers more favorable tradeoffs between the stabilization goals appearing in the social welfare function. Delegating joint price and wage targets, however, nearly replicates the commitment policy from a timeless perspective.
