The weekly demand and supply for corn is given by the following equations where P is the price (in cents) per ear of corn, and Q is the number of ears of corn in thousands. Qd = 140- 10P and Qs = -10 + 5P. Since corn can be used for ethanol production, the government wishes to stimulate corn production. Thus, it sets a price of 12 per ear of corn. Intructions: Use no decimals for final answers. PO is: QO is: The governement stimulus is an example of: O Price Floor, ES O Price Ceiling, ES Shift S to the right due to subsidies O Shift S to the right due to taxes The ES/ED is: quantities At P = $12, the quantities traded are: CSO is: PSO is: CS1 at P=12 is: PS1 at P=12 is: Who benefits from this stimulus? O Producers benefits because PS1 > PSO. O No one benefits. Consumers and suppliers are hurt since CS1 CSO. O Producers benefits, but consumers are hurt since CS1
