An option trader is attempting to judge whether an option's premium is cheap or expensive. To do so, he employs a GARCH(1,1) model to forecast volatility. The particular model he estimates has an intercept term equal to 0.000005, a parameter estimate on the latest estimate of variance of 0.85, and a parameter estimate on the latest innovation of 0.13. If the latest volatility estimate from the model were 2.2% per day and the option's underlying asset changed 3%, the trader's estimate of the next period's standard deviation is closest to:

Uestion 7 you hold a portfolio consisting of a $5,000 investment in each of 20 different stocks. the portfolio beta is equal to 1.12. you have decided to sell a coal mining stock (b = 1.00) at $5,000 net and use the proceeds to buy a like amount of a mineral rights company stock (b = 2.00). what is the new beta of the portfolio?

4. suppose that pollution in a neighborhood comes from two factories, with marginal benefit curves given by mb1 = 12 – p1 and mb2 = 8 – p2. the level of pollution in the neighborhood is given by p = p1 + p2. the government wants to limit pollution by instituting a pollution-rights market. the government’s desired level of p is 10, so it prints 10 pollution rights and offers them for sale to the firms.a)find the equilibrium selling price of a pollution right, as well as the allocation of rights (and hence pollution levels) across the two factories. b)repeat part (a) for the case where the government’s desired level of pollution equals 14. c)comment on the usefulness of a pollution rights market in achieving efficient levels of pollution abatement.

Both renewable and nonrenewable resources are used within our society. how do the uses of nonrenewable resources compare to the uses of renewable resources?
