E1

Pr(deny =
= 1|P/I ratio, black) = 0(-2.26 + 2.74 P/I ratio + 0.71 black)
!!
(0.16) (0.44)
(0.083)
Use the estimated probit model above to answer the following questions (standard errors of
the estimators are in the parenthesis):
• a. A black mortgage applicant has a P/I ratio of 0.35. What is the probability that his
application will be denied?
• b. Suppose that the applicant reduced this ratio to 0.30. What effect would this have on
his probability of being denied a mortgage?
• c. Repeat (a) and (b) for a white applicant.
• d. Does the marginal effect of the P/I ratio on the probability of mortgage denial depend
on race? Explain.
