Causal Inference by Independent Component Analysis: Theory and Applications*

Abstract: Structural vector‐autoregressive models are potentially very useful tools for guiding both macro‐ and microeconomic policy. In this study, we present a recently developed method for estimating such models, which uses non‐normality to recover the causal structure underlying the observations. We show how the method can be applied to both microeconomic data (to study the processes of firm growth and firm performance) and macroeconomic data (to analyse the effects of monetary policy).

“…This is done using the algorithm in Moneta et al (2013), which applies an Independent Component Analysis (ICA) to recover the latent components that are fully statistically independent, before they are arranged in a causal ordering that best fits the data. We begin by estimating a reduced-form VAR to obtain the residuals ̂ then apply ICA to decompose the residuals into statistically independent shocks ̂ Then, the rows are permuted to obtain an estimate of a lower-triangular matrix with zeroes along the diagonal.…”

“…The developments to which we refer, brought to the attention of the economic research community by Moneta et al (2013), are based upon a deeper investigation of what the assumption of independence of the exogenous shocks (Et in Equation 1) entails.…”

“…The assumptions of independence and of non-Gaussianity of the shocks are not sufficient to identify the structural form (1); we need the third assumption that there is no contemporaneous feedback among the variables, which Moneta et al (2013) refer to as the "acyclicality" assump-tion. It must be interpreted as follows: if, in our model, an exogenous shock to one variable is immediately able (within one time-unit, that is within one year in our context) to affect a second variable, then it is not possible that an exogenous shock to the second variable is immediately able to affect the first variable.…”

“…Besides, the variables imports, dependency ratio and population density were dropped after tests of stationary proved them to be of different order of integration. Moreover, the statistical performance of the estimates from VAR and VEC models has been well studied and well established for models with a few number of variables (Moneta et al, 2011).…”
