We propose a statistical identification procedure for structural vector autoregressive (VAR) models that present a nonlinear dependence (at least) at the contemporaneous level. By applying and adapting results from the literature on causal discovery with continuous additive noise models to...

We propose a statistical identification procedure for recursive structural vector autoregressive (VAR) models that present a nonlinear dependence (at least) at the contemporaneous level. By applying and adapting results from the literature on causal discovery with continuous additive noise...

A methodology for high dimensional causal inference in a time series context is introduced. It is assumed that there is a monotonic transformation of the data such that the dynamics of the transformed variables are described by a Gaussian vector autoregressive process. This is tantamount to...

When the number of variables is larger than the number of structural shocks driving the economy, the associated structural VAR system is said to be singular. We propose an identification method for singular structural VAR models contaminated by noise that combines a collapsing procedure with the...

Starting from the theoretical observation that the identification problem of SVAR models is fundamentally a problem of variable aggregation, we propose a new identification method based on nowcasted macroeconomic data, i.e. on macroeconomic series reconstructed at high-frequency. The idea is...

We propose an identification method for singular structural VAR models contaminated by noise that combines a collapsing procedure with the...

The price-bubble and crash formation process is theoretically investigated in a two-asset equilibrium model. Sufficient and necessary conditions are derived for the existence of average equilibrium price dynamics of different agent-based models, where agents are distinguished in terms of factor...

Portfolio recommendations should include, beyond an estimate of the expected return on the investment, also an assessment of the associated level of risk. This paper introduces a simple methodology to assign stock recommendations based on a firm valuation procedure that replaces the conventional...
