Bonus Question 1 (5 points) Counterfactual Scenario (for educational purposes): Ref: WSJ Suppose that on September 17, 2025, the Federal Reserve decreases the federal funds rate by 0.25 percentage points. Imagine that, in this hypothetical scenario, mortgage rates are also expected to decrease. A fall in mortgage rates lowers the cost of borrowing, making housing more affordable to consumers. From the perspective of demand theory, the demand curve for the housing market will (1)____________ (increase or decrease; 1 point). Now suppose that, at the same time, tariffs are imposed on imported construction materials. As a result, the prices of key inputs such as steel, lumber, and cement increase, raising the overall cost of constructing new homes. From the perspective of supply side, the supply curve for the housing market will (2)____________ (increase or decrease; 1 point). In this counterfactual setting, we expect the equilibrium price of houses to (3)_______________ (increase or decrease; 3 points). However, the equilibrium quantity of houses could either increase or decrease depending on the relative magnitudes of the demand shift (from cheaper financing) and the supply shift (from higher construction costs). Write your answers: (1)____________[1 point] (2)____________[1 point] (3)____________[3 points]
