Section [ ]. Copper as the primary contested good
The hypothesis about copper being a key contested good in the boom period of 1927-29 is made even more plausible if we compare the dynamics of copper prices with the behavior of refined copper shipments (Fig. [ ]). It is clear that the pattern evidenced by the chart is exactly the one that our version of ABCT predicts – the growth in copper price was significantly lagging that in the copper shipments.
