Assume the price of product A increases from $1 to $1.50, while the price of competing product B increases from $1.50 to $2.00. Based on the information, what we can say about the absolute and relative price differences between the two products and the relative attractiveness of the two products to consumers.

The coffee and tea demand functions depend on both prices. Suppose the demand curves for coffee and tea are Qc = 120 − 2pc + pt and Qt = 90 − 2pt + pc, where Qc is the quantity of coffee, Qt is the quantity of tea, pc is the price of coffee, and pt is the price of tea. These crops are grown in separate parts of the world, so their supply curves are not interrelated. We assume that the short-run, inelastic supply curves for coffee and tea are Qc = 45 and Qt = 30. Solve for the equilibrium prices and quantities. Now suppose that a freeze shifts the short-run supply curve of coffee to Qc = 30. How does the freeze affect the prices and quantities

Suppose that the world price of oil is roughly $100.00 per barrel and that the world demand and total world supply of oil equal 34 billion barrels per year (bb/yr), with a competitive supply of 20 bb/yr and 14 bb/yr from OPEC. Statistical studies have shown that the short−run price elasticity of demand for oil is −0.05, and the short−run competitive price elasticity of supply is 0.10. Using this information, derive linear demand and competitive supply curves for oil. Let the demand curve be of the general form Q=a−bP and the competitive supply curve be of the general form Q=c+dP, where a, b, c, and d are constants. The equation for the short−run demand curve is? The equation for the short−run competitive supply curve is
