Andy's monthly demand (in number of bars) for "Clif Builder's" protein bars is given by 9 = 8 - 2P + (I - T) /1000, where I is Andy's monthly income, T is his monthly income tax expense and P is the price of Clif bars. a) Suppose the price of Clif bars is $3.00, Andy's monthly income is $7,500, and his monthly income tax expense is $2,500. Calculate Andy's Clif bar consumption at that price, and determine his consumer surplus. b) Suppose Andy's income tax expense is decreased by 40% (his income and the price of Clif bars remain the same. Calculate the change in Andy's consumption and the change in his consumer surplus after the tax decrease. c) Illustrate your answers to parts a) and b) on a graph. Briefly explain.

The demand function for apples is the following. Qn = 10 – Pn + 0.2Y +0.5 Pc – 2Ps + 0.2A Where: Qn = annual sales of apples (millions of kilos) Pn = price of apples (£1 per kilo) Y  = disposable income in the UK £trillions (£10 trillions) Pc = price of a pies £ per kilo (£2 per kilo) Ps = price of pear (£2 per kilo) A = advertising measured in hundreds of thousands of £5 (use as 5 in your calculations)   Q. How much will the demanded quantity change if the price of apples increases to 1.5? a. It will decrease by 0.4 million kilos. b. It will decrease by 0.5 million kilos. c. It will increase by 2 million kilos. d. It will increase by 0.5 million kilos. e. All the other answers are wrong.

You can drag and drop files here to add them. Consider the public policy aimed at smoking: (a) Suppose studies indicate that the price elasticity of demand for cigarettes is about 2. If the government is able to increase the price of a pack of cigarette from $2 to $3 (through may be, higher taxes), by what percentage will the consumption (demand) of cigarettes decrease? Please show all calculations. (b) Studies also find that the price elasticity of demand for cigarettes for higher income earners is more inelastic compared to that of those earning less income.
