Suppose that Mr. X has a useless tree growing in his yard that has become too large, and he must cut it down within the next four years. Cutting down the tree requires effort, and he would like to wait and cut down the tree later. However, each year that he delays, the tree gets bigger and requires even more effort to cut down. Specifically, suppose that the effort cost to cut down the tree in year 7 is c(7), where c(1) = 24, c(2) = 29, c(3) = 36, and c(4) = 48. Suppose that Mr. X is an exponential discounter with discount factor 6, and that the only utility consequence of cutting down the tree is the disutility of effort experienced when the tree is cut. (a) From a year-l perspective, as a function of 8, when is Mr. X's preferred time to cut down the tree? (b) Suppose Mr. X does not cut down the tree in year 1. From a year-2 perspective, as a function of 8, when is Mr. X's preferred time to cut down the tree? Is there any d for which Mr. X's year-2 preferences differ from his year-1 preferences?

All else being equal, which is true about a firm with high operating leverage relative to a firm with low operating leverage? select one: a. a higher percentage of the high operating leverage firm's costs are fixed. b. the high operating leverage firm is exposed to less risk. c. the debt payments limit the high operating leverage firm's opportunities to turn a big profit. d. the high operating leverage firm has more debt.

What’s the best type of healthcare plan

A) plot the m1 and m2 money stock in the us from 1990-2015. (hint: you may use the data tools provided by fred.) (b) plot the nominal interest rate from 1960 to 2014. (hint: you can either use the daily interest rates for selected u.s. treasury, private money market and capital market instruments from or the effective federal funds rate fromfred.) (c) the consumer price index (cpi) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. intuitively, the cpi represents the cost of living or the average price level. plot the cpi from 1960 to 2013.(d) the inflation rate is the yearly percentage change in the average price level. in practice, we usually use the percentage change in the cpi to compute the inflation rate. plot the inflation rate from 1960 to 2013.(e) explain the difference between the ex-ante and ex-post real interest rate. use the fisher equation to compute the ex-post real interest rate. plot the nominal interest rate and the ex-post real interest rate from 1960 to 2013 in the same graph.
