related to the notion of nonfundamentalness, under which structural economic shocks cannot be recovered from an estimated … causal VAR model. As detecting nonfundamentalness is therefore of great importance, we propose a procedure for discriminating … between causality and noncausality that can be seen as a test of nonfundamentalness. The methods are illustrated with …

We review, under a historical perspective, the development of the problem of nonfundamentalness of Moving Average (MA …) representations of economic models. Nonfundamentalness typically arises when agents’ information space is larger than the …, nonfundamental representations should not be ruled out by assumption and indeed methods to detect nonfundamentalness have been …
