“…We intend to verify whether the recent evidences on the increase in centralization of capital in terms of network control (Brancaccio et al 2018) have causal relations with the fluctuations of the GDP around its trend and with monetary policy guidelines in the USA and in the Euro Area between 2001 and 2016. More specifically, we intend to check whether it is possible to find empirical evidences of the theses according to which: 1) monetary policies can have an impact on the solvency conditions in the economic system and the related centralization of capital Fontana 2013, 2016; see also Radcliffe Report 1959;Kaldor 1985;Aikman et al 2016); and 2) capital centralization, in turn, can cause economic depression (Hilferding, 1910;Magdoff and Sweezy, 1987;Lazonick, 1992;Crotty, 1993;Sweezy, 1994;Dore, 2008;Foster et al, 2011). For these scopes, as we shall see in the following sections, we propose an original application of B-VAR analysis on policy interest rates, network control and GDP fluctuations around its trend for USA and Euro Area in the period 2001-2016, before and after the socalled great financial crisis.…”
