The analysis of tooth shrinkage by C. Loring Brace and colleagues at the University of Michigan’s Museum of Anthropology indicates that human tooth size is con-tinuing to decrease and that the evolutionary process has not yet come to a halt. In northern Europeans, for example, tooth size reduction now has a rate of 1% per 1000 years. a. If t represents time in years and y represents tooth size, use the condition that y = 0.99y0 when t = 1000 to find the value of k in the equation y = y0 ekt. Then use this value of k to answer the following questions. b. In about how many years will human teeth be 90% of their present size? c. What will be our descendants’ tooth size 20,000 years from now (as a percentage of our present tooth size)?

In an effort to make the distribution of income more nearly equal, the government of a country passes a tax law that changes the Lorenz curve from y = 0.98x2.1for one year to y = 0.32x2 + 0.68x for the next year. Find the Gini coefficient of income for both years. (Round your answers to three decimal places.) after before

The following facts about a company are known: 1. At present, its total capital is £3 million. 2. It has just sold zero-coupon bonds with the total nominal value of £2 million which it promises to repay in 18 months from now. 3. The total capital F(t) of the company follows the geometric Brownian motion with parameters µ = 0.15 and σ = 0.2. The continuously compounded annual interest rate r = 6%. Within the framework of the Merton model, establish the following. (c)What is the probability that the company would default on its promise to bond holders?
