Abstract
In recent decades, most advanced and developing economies have suffered—or are still suffering—from profound and repeated crises. The literature has reflected on the determinants of these perturbations by placing particular emphasis on the malfunctioning of either the real or financial sphere of the economy. The main research question has been to understand whether it was the real economy that perturbed finance sectors or, alternatively, the financial/credit market that depressed real production. Whatever the direction of the causality nexus and, consequently the origin of the attack, with some studies identifying the direction from real markets to financial sectors (see Bernanke and Gertler 1989; Greenwald and Stiglitz 1993; Delli Gatti et al. 2012) and others reversing it (see Christiano and Ikeda 2011; Brunnermeier et al. 2012), what is certainly undoubted is the self-reinforcing interaction between the two sectors, which translates into booms followed by busts. In light of this, part of the literature has not focused as much on the origin of crises, but rather on the mechanisms of shock propagation. In this regard, many studies have shown that a combination of forces is needed to generate shock transmission. Specifically, the literature on contagion has shown that agents’ interaction and the emerging network topology are key ingredients for the spread of systemic risk (see, for instance, Lux 2016; Lux and Montagna 2017).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
