We find that both industrial activity and world GDP correlate with total scrap supply, with limited dependence on copper price.
Accordingly, the estimation results conducted in the cointegration framework over the period 1994q1–2012q4 reveal the existence of a long-run equilibrium relationship between the real copper price and real kwacha/US$ exchange rate.

Copper extraction is distinctly profitable when the selling price of copper is ∼$2.5 per kg, whereas it is unprofitable when the selling price falls below $1.5 per kg.
From the short-run and long-run causality tests, we determine that the futures market plays an important role in transmitting price information to other copper markets while such information flow is not found for the brass scrap market.
The authors propose to price copper access based on the modern equivalent asset (MEA) of fiber access.
The results identify two cycles of copper prices and price forecasts in the short term.
The results reveal that, financial speculation accentuated copper price moves during the last decade.
Our results indicate that the impact of international copper price shocks on China's PPI is time-varying.

The application to the U. S. refined copper market provides estimates of structural supply and demand, rational price forecasts, and the risk of copper storage that is consistent with modern portfolio theory.
This study, therefore, provides new insights into price determination on the LME copper market, and resolves the ambiguity of previous research regarding the efficiency of that market.
Second, it is shown that a partially integrated copper producer may find rationing profitable as a means of partially achieving the effects of price discrimination given that price discrimination itself is infeasible.
Our analysis reveals that a significant proportion of future copper supply involves factors that are not immediately price-sensitive, and that a rapid unlocking of these ore bodies could have negative ramifications for economic growth, human development, and the transition to a low carbon future.
