Question 1 4 pts Peter will receive monthly payments of $800 for the next 5 years. The required return is 12 percent. Only need to input formula with numbers, no calculation needed. a) What is the present value if payments are paid at the end of each month (i.e., first payment takes place in month 1)? b) What is the present value if payments are paid at the beginning of each month (i.e., first payment takes place now)?

1. Multiple Choice: (a) The major flaw of the linear probability model is that a. the actuals can only be 0 and 1, but the predicted are almost always different from that. b. the regression $R^2$ cannot be used as a measure of fit. c. people do not always make clear-cut decisions. d. the predicted values can lie above 1 and below 0. (b) The probit model a. is the same as the linear probability model. b. always gives the same fit for the predicted values as the linear probability model for values between 0.1 and 0.9. c. forces the predicted values to lie between 0 and 1. d. should not be used since it is too complicated. (c) The linear probability model is a. the application of the multiple regression model with a continuous left- hand side variable and a binary variable as at least one of the regressors. b. an example of probit estimation. c. another word for probit estimation. d. the application of the linear multiple regression model to a binary depen- dent variable. (d) In the probit model $Pr(Y = 1) = \Phi(\beta_0 + \beta_1X)$, $\Phi$ a. is not defined for $\Phi(0)$. b. is the standard normal cumulative distribution function. c. is set to 1.96. d. can be computed from the standard normal density function. (e) In the expression $Pr(Y = 1) = \Phi(\beta_0 + \beta_1X)$, a. $(\beta_0 + \beta_1X)$ plays the role of the random variable z in the cumulative standard normal distribution function. b. $\beta_1$ cannot be negative since probabilities have to lie between 0 and 1. c. $\beta_0$ cannot be negative since probabilities have to lie between 0 and 1. d. $min(\beta_0 + \beta_1X) > 0$ since probabilities have to lie between 0 and 1.
