Suppose you apply probit model to the mortgage denial analysis discussed in class. E [Y;\X¡1,… , X¡ik] = ¢ (Bo + X¡1ß1 + …+ X¡ikßr) The response variable Y_i takes the value 1 if the mortgage application was denied, O otherwise. (Here, the underscore "_" means "subscript". e.g. "Y_i" is read "Y subscript i".) The regressor X_i1 is the race dummy that takes value 1 if individual i belong to a minor race group. Other regressors X_i2,--.X_ik are variables that affect the decision making process of the reviewer. For example, applicant's income, wealth, employment status, other loan, and the

This option, if exercised, is worth an additional $1,800,000 to the landowner, but this will occur only if natural gas is discovered during the exploration phase. The landowner, believing that the energy company’s interest in the site is a good indication that gas is present, is tempted to develop the field herself. To do so, she must contract with local experts in natural gas exploration and development. The initial cost for such a contract is $300,000, which is lost forever if no gas is found on the site. If gas is discovered, however, the landowner expects to earn a net profit of $6,000,000. The landowner estimates the probability of finding gas on this site to be 60%. a. Use PrecisionTree to identify the strategy that maximizes the landowner’s expected net earnings from this opportunity. b. Perform a sensitivity analysis on the…
- Suppose that a consumer cannot vary hours of work as he or she chooses. In particular, he or she must choose between working q hours and not working at all, where q > 0. Suppose that dividend income is zero, and that the consumer pays a tax T if he or she works, and receives a benefit b when not working, interpreted as an unemployment insurance payment. a. If the wage rate increases, how does this affect the consumer’s hours of work? What does this have to say about what we would observe about the behavior of actual consumers when wages change? Explained also with the graph b. Suppose that the unemployment insurance benefit increases. How will this affect hours of work? Explain the implications of this for unemployment insurance programs. Explained also with the graphEnvironment-friendly agricultural practice includes the application of pesticides when it is really necessary, e.g., at the beginning of a pest emergence. Such practice, depending on the field conditions, and the reaction of growers, for the same level of "alert" inspired this question. Condition: There is a generalized emergence of pests in a given area. At this stage of the emergence, not all growers decide to apply pesticides, hoping that the emergence will be brief or without implication for their field. Accordingly, assume 75% of the growers in that area at that time decide to apply pesticides.1) What is the probability that among five growers randomly sampled, two decide not to apply pesticides? 2) What is the probability that among 10 randomly sampled growers, more than nine decide to apply pesticides?Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…

The will states how you must invest the money. Some (or all) of the money must be invested in stocks and bonds. The requirements are that at least $2000 be invested in bonds, with expected returns of $0.080 per dollar, and at least $1000 be invested in stocks, with expected returns of $0.13 per dollar. Because the stocks are medium risk, the final stipulation requires that the investment in bonds should never be less than the investment in stocks. How should the money be invested so as to maximize your expected returns? To maximize the expected returns, invest$ in bonds and $ in stocks.Suppose that in a closed economy GDP is equal to 11,000, taxes are equal to 2,500, consumption equals 7,000, and government purchases equal 3,000, the outcome is private saving and public savings2,500 and -1500,respectively.
