Problem Set 3 ECON 973 Fall 2012 Fluctuations: Discrete Time Models Ben Brewer 12/10/12 1. a. Given this two-period problem of labor supply maxc1 ‚n1 ‚c2 ‚n2 ln[c1 ] + ln[1 − n1 ] + βln[c2 ] + βln[1 − n2 ] subject to the intertemporal budget constraint c1 [1 + r] + c2 = w1 n1 [1 + r] + w2 n2 Dividing each side by [1+r] for convenience gives c1 + c2 w 2 n2 = w 1 n1 + 1+r 1+r We can solve for consumption and labor supply in each period (c1 ‚ c2 ‚ n1 ‚ n2 ) by first setting up the Lagrangian

Unit 1 Problem Set 1 26. Surgery Versus Splints A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery‚ there was a 92% success rate. Among 83 patients treated with splints‚ there was a 72% success rate. Calculations using those results showed that if there really is no difference in success rates between surgery and splints‚ then there is about 1 chance in 1000 of getting success rates like the ones obtained

Give an example of each scale of atmospheric motion; Micro‚ Meso and Macro. An example of a “Microscale” atmospheric motion would be a small‚ turbulent breeze blowing through the trees. A F3 tornado flowing across a Kansas corn field would be an example of a “Mesoscale” motion‚ and Super Storm Sandy would be a great example of a “Macroscale” motion. What causes an "eddy" to form? An “eddy” is formed when wind encounters a solid object‚ a whirl of air is formed on the object’s downward side. The

Economics 500 – Problem Set #3 Consider a firm producing an output Q using the two inputs “labor” (L) and “capital” (K) according to the production function Q = K.5L.5 (i.e.‚ the amount of output produced Q is equal to the square root of K times the square root of L). Suppose that the firm is in a short-run situation in which K is fixed at one unit (K = 1) but labor is variable. Suppose that the user cost of capital‚ r‚ is $48 for each unit of K and that the wage rate‚ w‚ the cost of one unit
