Answer No. 1 Production possibility curve is a particular form of curve‚ which shows the possibility of production in a particular economy (Gwartney‚ Stroup‚ Sobel‚ Macpherson p.28). In an economy‚ the resources are scarce‚ therefore‚ it is important for the economy to make sure that‚ it keeps a balance between the productions and utilizes its resources appropriately. If the production possibility curve of an economy will move outwards then‚ the long run supply curve will have a positive change

What assumption do you need to make? According to Lind‚ et al. (2005)‚ when population standard deviation is unknown‚ and the sample is smaller than 30‚ a t distribution should be used. We need to assume that the sample is from a normal population (pp. 291-293). c. For a 90 percent confidence interval‚ what is the value of t

Homework Problem Set 4 1. Because Q=12-2P inverse demand P = -0.5 Q+6 For “half price” case‚ P = 2.5‚ Q=7 consumer surplus = 7*(6-2.5)/2 = 12.25 For “buy one‚ get one free” case‚ when original P = 5‚ Q = 4 instead of 2‚ total benefit TB = (4+6)*4/2 = 20 On the other hand‚ payment is 2*5=10 dollars‚ so consumer surplus will be = 10 Thus “half price” gives more surplus. 2. cost minimizing manner‚ marginal product of typewriter/marginal product of word processor=rent of typewriter/rent
