1 Economics 103 Fall 2012: Short answer/graphing review questions for first midterm. Additional practice questions are in the text within and at the end of each chapter. Midterm is in class on Wednesday, October 10. Bring #2 pencil and a calculator. No telephone-based calculators are allowed. Make sure in your answers that you identify all axes, curves and original and new points of equilibrium and all other relevant points. 1. Trade unions in the steel industry get an agreement for annual wage increases. At the same time, coal, an input to steel, is made more expensive by a strike of coal workers. Draw on a graph and explain in words what happens to the market equilibrium price and quantity of steel once these two changes have happened. 2. The price of car oil filters rises. Explain in words and show on a graph what happens in the market for car oil. 3. UMass raises its tuition so the income students can spend on pizza falls. Show on a graph and explain in words what happens in the pizza market. 4. You wake up this morning to read in the Collegian that sugar helps the brain recover faster from study exhaustion. Show on a graph and explain in words what happens in the market for sugar. 5. Draw and explain in words the shape of the following demand curves: perfectly elastic, perfectly inelastic and unitary elastic. 6. Demonstrate on a graph and explain in words (making reference to the elasticity formula) why elasticity of demand varies along a straight line demand curve. 7. Demonstrate on a graph and explain in words the deadweight loss that would occur if construction of new rental units was prohibited in Amherst. Be sure to explain where the point of efficiency is and why after the prohibition the new output level would be inefficient. 8. The cross elasticity of demand for two goods is greater than zero. Explain what the relationship is between these two goods and draw on a graph what

2 happens to in the market for the first good if the price of the second good falls. 9. Draw on a graph and explain in words the concept of Utilitarian Fairness. What is the implication of Utilitarian Fairness for income redistribution? Who should be the beneficiaries of redistribution and why? 10. Demonstrate on a graph and explain in words the incidence of a tax on buyers, then do the same for a tax on sellers. Draw these graphs with a demand curve with a low elasticity of demand. Then draw either the seller or the buyer tax case with a very elastic demand curve and explain the difference between the low elasticity and the high elasticity case with reference to the difference between the pre- tax and post- tax equilibrium price and quantity.
