In la ion a ge ing and business cycle synch oniza ion
Mac oeconomic policy plays a c ucial ole in shaping he deg ee o business cycle synch oniza ion (BCS).

In summa y, mac oeconomic policy, especially in la ion a ge ing, in luences he synch oniza ion o

Thus, while cen al bank independence can b ing sho - e m bene i s by s eng hening he ela ion-
