<<Optimal Monetary Policy Rules and House Prices: The Role of Financial Frictions>>
此篇论文发表在2015年Journal of Money, Credit and Banking上。 作者通过建立新凯恩斯模型（包括房地产领域以及金融危机对房地产领域的影响）来探讨针对房价较为合理的货币政策。
简介
We probe the scope for reacting to house prices in simple and implementable monetary policy rules, using a New Keynesian model with a housing sector and financial frictions on the household side. We show that the social-welfare-maximizing monetary policy rule features a reaction to house price variations, when the latter are generated by housing demand or financial shocks. The sign and size of the reaction crucially depend on the degree of financial frictions in the economy. When the share of constrained agents is relatively small, the optimal reaction is negative, implying that the central bank must move the policy rate in the opposite direction with respect to house prices. However, when the economy is characterized by a sufficiently high average loan-to-value ratio, then it becomes optimal to counter house price increases by raising the policy rate.
