Climate change is one of the biggest economic challenges of our time. Given the scale of the problem, the question of whether a carbon tax should be introduced is hotly debated in policy circles. This paper studies the optimal design of a carbon tax when environmental factors, such as air carbon...

How does contagion risk affect the business cycle? We find that the presence of contagion risk significantly alters the transmission of standard macroeconomic shocks. Relative to the first-best equilibrium, the contagion externality significantly reduces the response of output to a technology...

This paper studies the design of Ramsey optimal monetary policy in a Health New Keynesian (HeNK) model with Susceptible, Infected and Recovered (SIR) agents. The nonlinear model is estimated with maximum likelihood techniques on Euro Area data. Our objective is to deconstruct the mechanism by...

Almost two decades after the introduction of the common currency, differences in institutional frameworks remain a major source of cross-country heterogeneity in the eurozone. We develop a two-country model with incomplete international markets in which the availability of credit depends on the...

This paper studies the cyclical properties of real GDP, house prices, credit, and nominal liquid financial assets in 17 EU countries, by applying several methods to extract cycles. The estimates confirm earlier findings of large medium-term cycles in credit volumes and house prices. GDP appears...

How do cyclical fiscal stabilisation policies affect welfare and government bond risk premia? Using a new Keynesian model we find that the effects of fiscal policy rules on the bond premium and welfare crucially depend on the source of business cycle fluctuations. The overall effect is estimated...

This paper studies the effects of imperfect risk-sharing between lenders and borrowers on commercial property prices and leverage. The key friction is that agents use different discount rates to evaluate future flows. Eliminating this pecuniary externality generates large reductions in the...

This study finds that a model with internal habit memory allowsto simultaneously explain a series of business cycle and asset pricing puzzles. Compared to the literature, the equity premium puzzle can be resolved in a model with endogenous labor, without giving rise to excessive risk free rate...

The main contribution of this work is to provide a dynamic general equilibrium model of asset allocation, allowing to reconcile economic theory with several puzzling contradictions recently pointed out in the literature: (i) the asset allocation puzzle, (ii) the observed time-variation in...

The aim of this study is to develop a general equilibrium framework linking real estate prices to the real economy. The model is evaluated in terms of its ability to explain: (i) the high volatility of residential real estate prices, (ii) the fact that commercial real estate prices are more...
