We examine the effects of various borrower-based macroprudential tools in a New Keynesian environment where both real and nominal interest rates are low. Our model features long-term debt, housing transaction costs and a zero-lower bound constraint on policy rates. We find that the long-term costs, in terms of forgone consumption, of all the macroprudential tools we consider are moderate. Even so, the short-term costs differ dramatically between alternative tools. Specifically, a loan-to-value tightening is more than twice as contractionary compared to loan-to-income tightening when debt is high and monetary policy cannot accommodate.
We analyse the effects of macroprudential and monetary policies and their interactions using an estimated dynamic stochastic general equilibrium (DSGE) model tailored to Sweden. Households face a ceiling on their loan-to-value ratio and must amortize their mortgages. The government grants mortgage interest payment deductions. Lending rates are affected by mortgage risk weights. We find that demand-side macroprudential measures are more effective in curbing household debt ratios than monetary policy, and they are less costly in terms of foregone consumption. A tighter macroprudential stance is also found to be welfare improving, by promoting lower consumption volatility in response to shocks, especially when using a combination of macroprudential instruments.
An integrated analysis of how financial frictions can be accounted for in macroeconomic models built to study monetary policy and macroprudential regulation. Since the global financial crisis, there has been a renewed effort to emphasize financial frictions in designing closed- and open-economy macroeconomic models for monetary and macroprudential policy analysis. Drawing on the extensive literature of the past decade as well as his own contributions, in this book Pierre-Richard Agénor provides a unified set of theoretical and quantitative macroeconomic models with financial frictions to explore issues that have emerged in the wake of the crisis. These include the need to understand better ...
A concise but rigorous and thorough introduction to modern macroeconomic theory. This book offers an introduction to modern macroeconomic theory. It is concise but rigorous and broad, covering all major areas in mainstream macroeconomics today and showing how macroeconomic models build on and relate to each other. The self-contained text begins with models of individual decision makers, proceeds to models of general equilibrium without and with friction, and, finally, presents positive and normative theories of economic policy. After a review of the microeconomic foundations of macroeconomics, the book analyzes the household optimization problem, the representative household model, and the o...
The latest World Economic Outlook reports economic activity was surprisingly resilient through the global disinflation of 2022–23, despite significant central bank interest rate hikes to restore price stability. Risks to the global outlook are now broadly balanced compared with last year. Monetary policy should ensure that inflation touches down smoothly, while a renewed focus on fiscal consolidation is needed to rebuild room for budgetary maneuver and to ensure debt sustainability. Structural reforms are crucial to revive medium-term growth prospects amid constrained policy space.
Les politiques monétaires ont gagné une popularité considérable depuis une vingtaine d'années. Les dirigeants des banques centrales sont devenus des "vedettes" de l'actualité, dont les propos et les actes sont examinés à la loupe. Pour les comprendre, il pouvoir répondre aux deux questions clefs suivantes : - Que peut faire une politique monétaire pour maintenir la stabilité des prix, modérer les fluctuations et promouvoir une croissance plus forte ? - Quelles sont les stratégies possibles et effectivement retenues par les grandes banques centrales pour rendre leurs actions plus efficaces ? Explorant une littérature complexe et foisonnante, l'ouvrage donne une série d'éclaira...
