13. The demand for good X satisfies the following relation (where \"In\" is natural logarithmic function): 1.3 Income' InQy =193 -39In Py 0.5In Py + where Py is the price of good X, Py is the price of good Y and Income is the income. At one equilibrium, @x = 150, Py = 4 and Py = 8. At this equilibrium, the own-price elasticity of demand for good X is [ Answerl3A | and the cross-price elasticity of demand for good X with respect to the price of good Y is [ Answerl3B |. Please refer to the background information below to answer the following two questions. Consider the following demand and supply schedule of potato chips. Price ($ per unit) Quantity Demanded (units) Quantity Supplied (units) 40 665 440 43 650 470 46 635 500 49 620 530 02 605 260 D9 590 290 h8 575 620 61 560 650 64 545 680 67 530 710 70 515 740 73 500 770 76 485 800 79 470 830 14. Suppose initially the potato chips market is in an unregulated equilibrium. If the government imposes a subsidy of $18 for each unit of potato chips sold, at the new equilibrium, the price received by the sellers will be $| Answerl14 | per unit. 15. Consequently, the government's subsidy expenditure will be $[ Answerl5 |
