We propose a new non-linear single-factor asset pricing model. Despite its parsimony, this model represents exactly any non-linear model with an arbitrary number of factors and loadings - a consequence of the Kolmogorov-Arnold representation theorem. It features only one pricing component...

We show that the higher-orders and their interactions of the common sparse linear factors can effectively subsume the factor zoo. We propose a forward selection Fama-MacBeth procedure as a method to estimate a high-dimensional stochastic discount factor model, isolating the most relevant...

In this paper we investigate the role of macroeconomic stabilization policies for the international transmission of productivity shocks and their effects on the external sector. We develop a two-country stochastic Dynamic New-Keynesian “perpetual youth” model of the business cycle with...

A relevant and current policy debate is whether banking supervision should be assigned to the same institution (the central bank) that is responsible for monetary policy. This paper reviews the theoretical arguments advanced in favour and against the solution of having banking supervision...

In this paper we investigate the role of macroeconomic stabilization policies for the international transmission of productivity shocks and their eects on the external sector. We develop a two-country stochastic Dynamic New-Keynesian \perpetual youth" model of the business cycle with incomplete...
