We investigate how the excess comovement of commodity prices, that is, the correlation in commodity returns after filtering out common fundamental shocks, has changed over the past three decades by developing the smooth-transition dynamic conditional correlation model that can capture long-run...

We investigate how the excess comovement of commodity prices, that is, the correlation in commodity returns after filtering out common fundamental shocks, has changed over the past three decades by developing the smooth-transition dynamic conditional correlation model that can capture long-run...

In this paper, we investigate whether and how excess comovement among commodity returns i.e., correlation among commodity returns not accounted for by the common shocks of exogenous macroeconomic variables, have increased during these decades. To this end, we generalize the model of excess...
