ambiguous c Qcoffee increases Pcoffee ambiguous d Qcoffee decreases Pcoffee ambiguous e None of the above 4 Someone made the observation that when income increases by 31 the quantity demanded of spam increases by 32 If this is indeed true this means that a The demand for spam is inelastic b The demand for spam is unit elastic c The demand for spam is elastic d Spam is a normal good e Spam is an inferior good 5 Suppose that widgets are a normal good and that when income goes up the quantity demanded of widgets stayed the same and the price of widgets increased Which of the following statements about the widget market could be true a The demand for widgets is unit elastic and the supply for widgets is perfectly inelastic b The demand and supply for widgets are both perfectly elastic c The demand and supply for widgets are both perfectly inelastic d The demand for widgets is perfectly inelastic and the supply for widget is perfectly elastic e None of the above Refer to the diagram below for questions 6 13 Suppose that the market is currently unregulated and in equilibrium 6 What is consumer surplus in this market a 7 5 b 9 c 12 5 d 18 e 25 7 What is producer surplus in the market a 7 5 b 9 c 12 5 d 18 e 25 Suppose now a tax of 8 is imposed in the market 8 What is consumer surplus in the market a 0 b 2 5 c 3 d 3 5 e 5 9 What is the government revenue in the market a 0 b 8 c 16 d 24 e 32 10 What is the change in total surplus from the free market to the market with an 8 tax In other words what is the deadweight loss in the taxed market a 0 b 4 c 16 d 20 e 25 Suppose now instead of the 8 tax described above a price floor of 7 is imposed on the free market 11 What is consumer surplus in this market a 0 b 2 c 4 d 8 e Not enough information 12 What is producer surplus in this market a 0 b 1 c 11 d 30 e Not enough information 13 True or False The advantage of having a 7 price floor instead of an 8 tax is that there will always be less deadweight loss and hence less inefficiency in the market with the price floor a True b False 14 Why is the First Welfare Theorem such an amazing result for competitive markets where there are no externalities a It proves that whenever markets are controlled by a visible hand such as a government the greatest efficiency will be achieved b It proves that the free market is in fact not efficient as any allocation where there is at least some government intervention is more efficient c It proves that supply does not need to equal demand in equilibrium d It proves that the most efficient allocation is indeed the one where everyone gets the same amount of surplus in other words efficient equals equitable e It proves that having a free market results in the same total surplus as having someone allocate consumption and production to get the greatest total surplus 15 Suppose that cheesecake is a luxury good and imagine your income increases Which statement is the most accurate a your total
