     In the other meaning of the term “real,” however—the sense from which springs the label “real business cycle,” namely, a cycle unrelated to monetary developments—the evidence adduced here for the importance of comovements between financial and real variables suggests that the cycle is not “real” at all or, at the least, not completely divorced from monetary developments.
