To test for discriminatio in the mortgage loan market, a linear probability model can be used:
approve = Beta0 + Beta'white' + other factors
a) Regress approve on white. What is interpretation of the estimated coefficient on white? IS it statistically significant? Is it economically siginficant (practically large)?
b) As controls, add the variables hrat, obrat, loanprc, unem, male, married, dep, sch, cosign, pubrec, martlat1, mortlaat2, and vr. What happens to the coefficient on white? Is there still evidence of race discirmination?
