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...

Previous research document the existence of long-run trends in comovements in the stock and bond markets. Following these findings, this paper examines possible trends in stock- bond return correlations. To this end, we introduce a trend component into a smooth transition regression (STR) model...
