Around 2007, the world copper price was $2.00 per pound and 12 million metric tons per year was the quantity transacted. A) Assume copper’s demand elasticity is -.5 and supply elasticity is 1.5. From this information, assuming that copper supply and demand curves are linear (in price), derive their equations. B) Now, in addition, I told you that demand for copper is also linear in income and that copper’s income elasticity is 1.3, would you be able to predict, the impact on equilibrium price for a 1% increase in income? Original income is not needed to answer this question.
