A NOTE ON SIMPLE MONETARY POLICY RULES WITH LABOR MARKET AND FINANCIAL FRICTIONS

摘要

We consider a New-Keynesian model with financial and labor market frictions where firms borrowing is limited by the enforcement constraint. The wage is set in a bargaining process where the firm's shareholder and worker share the production surplus. As debt service is considered to be a part of production costs, firms borrow to reduce the surplus which allows to lower the wage. We study the model's response to financial shock under two Taylor-type interest rate rules: first one responds to inflation and borrowing, second one to inflation and unemployment. We have found that the second rule delivers better policy in terms of the welfare measure. Additionally, we show that the feedback on unemployment in this rule depends on the extent of workers' bargaining power.
