• Introduction• Two persons (auditors) with matched characteristics such as age, sex, and
income • Equally eligible for the housing unitDirect methods of measuring of
discrimination
• Except one is black and one is white.• The paper examines the severity of differential treatment• The audit was done in metropolitan Detroit.
•
• Auditing technique, average and marginal level of discrimination
• John Yinger (1986)
• Tai = a + bRi +eai
• Where a, is the audit i, the individual auditor, T is the treatment variable, R
is binary variable for minority status and e, is the random error.
• Yinger argues that the OLS estimator b for beta is unbiased
• However the standard error of b is biased
• He recommends a paired difference- of-means test that would remove the
bias from the standard error of b
• Blacks in Boston were informed 30% fewer units
• The model
• Dj + a0 + aj +Wj + sumBij + sumvik[CiCk] +gYt + eij
• i=1,2,….k
• j=1,1..10
• Y* = Bx +e
Existing theories of Discrimination1) The agent prejudice 2) The customer prejudice 3) The perceived preference4) The rip-off hypothesis

Conclusion
Conclusion
• Widespread discriminatory 1980 –1990
• Marginal discrimination higher than average discrimination
