“…This is precisely the type of structure usually assumed in econometric models, except that in some models the above structure contemplates the existence of feedback reactions (see Faliva, 1992;Faliva & Zoia, 1994). A very clear and instructive correspondence between typical kinds of graphical models and (parameters of) linear models is commented by Cox & Wermuth (2004).…”

This paper aims at displaying a synthetic view of the historical development and the current research concerning causal relationships, starting from the Aristotelian doctrine of causes, following with the main philosophical streams until the middle of the twentieth century, and commenting on the present intensive research work in the statistical domain. The philosophical survey dwells upon various concepts of cause, and some attempts towards picking out spurious causes. Concerning statistical modelling, factorial models and directed acyclic graphs are examined and compared. Special attention is devoted to randomization and pseudo-randomization (for observational studies) in view of avoiding the effect of possible confounders. An outline of the most common problems and pitfalls, encountered in modelling empirical data, closes the paper, with a warning to be very cautious in modelling and inferring conditional independence between variables.

“…namely the partial derivatives of the functions in the right-hand side of the equation system, with respect to the current endogenous variables, and the covariance matrix of contemporaneous disturbances (for details, see [15][16][17]). As shown in the aforesaid references, the diagnostic about the causal or interdependent nature of a model is provided by the topological structure of the matrices above, or more conveniently by the corresponding binary matrices, written D b f and b , which can be assumed to be known a priori.…”

Causality and interdependence analysis in linear econometric models with an application to fertility

This paper is an applied analysis of the causal structure of linear multi-equational econometric models. Its aim is to identify the kind of relationships linking the endogenous variables of the model, distinguishing between causal links and feedback loops. The investigation is first carried out within a deterministic framework and then moves on to show how the results may change inside a more realistic stochastic context. The causal analysis is then specifically applied to a linear simultaneous equation model explaining fertility rates. The analysis is carried out by means of a specific RATS programming code designed to show the specific nature of the relationships within the model.

“…Starting from this premise and following Strotz and Wold, 1960;Wold, 1964; and more recently Faliva, 1992;Faliva and Zoia, 1994); in this paper we have devised an operational method to distinguish the causal from the interdependent equations of a SEM. Other approaches for detecting feedback-loops arising in deterministic (error free) models are based on either graph or system theory (see e.g., Gilli 1992).…”

Simultaneous equation models (SEMs) are composed of relations which either represent unidirectional links, which entail a causal interpretation, or bidirectional links, due to feedback loops, which lead to the notion of interdependence. The issue is of prominent interest in several respects. Investigating the causal structure of a SEM, on the one hand, brings to light the theoretical assumptions behind the model and, on the other hand, pilots the choice of the befitting estimation method and of which policy to implement. This paper provides an operational method to distinguish causal relations from interdependent ones in SEMs, such as macro-econometric models, models in ecology, biology, demography, and so forth. It is shown that the causal structure of a system crucially rests on the feedback loops, which possibly affect the equations. These loops are associated to the non-null entries of the Hadamard product of matrices encoding the direct and indirect links among the SEM dependent variables. The effectiveness of feedbacks is verified with a Wald test based on the significance of the aforementioned non-null entries. An R package, SIRE (System of Interdependent/Recursive Equations), provides the operational completion of the methodological and analytic results of the paper. SIRE is applied to a macroeconomic model to illustrate how this type of analysis proves useful in clarifying the nature of the complex relations in SEMs.
