“…The increase in time-series data availability and advances in measurement have increased the scope for empirical research using time-varying measures of synchronicity, including, most popularly, those based on amplitude (Giannone and Reichlin, 2010;Kalemli-Ozcan et al, 2013a, 2013bCaporale et al, 2015).
