Task 2
(a) Replicate the descriptive statistics Table 1 on page 17 in the Orrenius and Zavodny paper.
Hint: You need to weight the observations somehow in this and all the subsequent tasks
to produce results that are identical to those in the Orrenius and Zavodny paper. 
(b) Comment the results from the table you created in (a).
 
Task 3
(a) Compare the sample means of employment and real weekly earnings for Mexicans and
Salvadorans, separately for men and women, as well as for less and more educated during
and after TPS. You should replicate the results in Table 2 on page 18 in the Orrenius and
Zavodny paper. In this task, it is not required to compute statistical signi cances, as is
done in the paper. 
(b) What can you infer about the impact of the TPS program based on the results in (a)? 

Task 4
Use robust standard errors when doing regressions in Tasks 4 and 5.
(a) Analyze the e ects of the TPS program on 7 di erent variables using Di erence-inDi erences models where you compare Salvadorans and Mexicans, separately for men
and women, as well as less and more educated. You should replicate the results in Table
3 on page 19 in the Orrenius and Zavodny paper. Hint: Check the notes from Table 3 for
the correct speci cations. For the weekly earnings, consider using the natural logarithms
of the variables.
(b) Interpret the results from the table you produced in (a). 

Task 5
(a) Run a falsi cation test where you compare Salvadoran and Mexican immigrants that
arrived in 1994 1995 to those arrived in 1997 1998. Use the same speci cations as in Task
4. You should replicate the results in Table 5 on page 21 in the Orrenius and Zavodny
paper. 
(b) What is the point of this kind of a test? 
Task 6
What are your  nal conclusions about the impact of the TPS program?

Note: Sample only includes immigrants ages 20-64 who reporting migrating to the United States
during 1999-2000 or 2002-2003 and not being a naturalized U.S. citizen. Real weekly earnings
and real weekly earnings in occupation (average earnings of U.S. natives in that occupation) are
conditional on being employed and adjusted for inflation using the CPI-W (2005 = 100).
Observations are weighted using the ACS person weights.
