We study the role of institutional characteristics of mortgage markets in affecting the strength and timing of the effects of monetary policy shocks on house prices and consumption in a sample of OECD countries. We document three facts: (1) there is significant divergence in the structure of...

We study how the structure of housing finance affects the transmission of monetary policy shocks. We document three main facts: first, the features of residential mortgage markets differ markedly across industrialized countries; second, and ac- cording to a wide range of indicators, the...

There is already a small literature emphasising the empirical failure of the New Keynesian IS curve, but it is not yet known if this failure reflects empirical problems associated with small samples or is rather a structural weakness of the underlying model. To address this question, in this...

We study the role of asset revaluation in the monetary transmission mechanism. We build an analytical heterogeneous-agents model with two main ingredients: i) rare disasters; ii) heterogeneous beliefs. The model captures time-varying risk premia and precautionary savings in a setting that nests...

This work is based on a new Keynesian theoretical model for an advanced economy, which incorporates overlapping generations to analyze a channel through which fluctuations in household financial wealth influence aggregate demand. The optimal monetary policy, corresponding to that of a central...

There is already a small literature emphasising the empirical failure of the New Keynesian IS curve, but it is not yet known if this failure reflects empirical problems associated with small samples or is rather a structural weakness of the underlying model. To address this question, in this...

We propose a theory of indebted demand, capturing the idea that large debt burdens by households and governments lower aggregate demand, and thus natural interest rates. At the core of the theory is the simple yet under-appreciated observation that borrowers and savers differ in their marginal...

We study optimal monetary policy during temporary supply contractions when aggregate demand has inertia and expansionary policy is constrained. In this environment, it is optimal to run the economy hot until supply recovers. Positive output gaps in the low-supply phase lessen the negative output...

We analyze optimal monetary policy and its implications for asset prices, when aggregate demand has inertia and responds to asset prices with a lag. If there is a negative output gap, the central bank optimally overshoots aggregate asset prices (asset prices are initially pushed above their...

We study the role of wealth effects, i.e. the revaluation of stocks, bonds, and human wealth, in the monetary policy transmission mechanism. The analysis of wealth effects requires to incorporate realistic asset-pricing dynamics and heterogeneous households' portfolios. Thus, we build an...
