We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

Can the aging process affect inflation? The prolonged decline of fertility and mortality rates induces a persistent downward pressure on the natural interest rate. If this development is not internalized by the monetary policy rule, inflation can be on a downward trend. Using the structure of a...

We develop a theoretical model that features a business cycle-dependent relation between out- put, price inflation and inflation expectations, augmenting the model by Svensson (1997) with a nonlinear Phillips curve that reflects the rationale underlying the capacity constraint theory (Macklem...

We characterise the evolution of the U.S. unemployment-inflation tradeoff since the late XIX century era via a Bayesian time-varying parameters structural VAR. The Great Inflation episode appears as historically unique along several dimensions. In particular, the shape of the "Phillips loop" -...

This paper estimates a hybrid New Keynesian model on euro area data and evaluates the performance of different simple policy rules and of the optimal unconstrained rule under commitment. The study reaches two main conclusions. First, inflation is found to be mainly forward-looking in the euro...

We propose a theoretical framework for assessing whether a forecast model estimated over one period can provide good forecasts over a subsequent period. We formalize this idea by defining a forecast breakdown as a situation in which the out-of-sample performance of the model, judged by some loss...

We propose a monetary model in which the unemployed satisfy the offcial US deffinition of unemployment: they are people without jobs who are (i) currently making concrete efforts to find work and (ii) willing and able to work. In addition, our model has the property that people searching for...
