1          The Mark of a Criminal Record (50 points)[1]

To isolate the causal e↵ect of a criminal record for black and white applicants, Pager ran an audit experiment. In this type of experiment, researchers present two similar people that di↵er only according to one trait thought to be the source of discrimination. This approach was used in the resume experiment described in Quantitative Social Science, where researchers randomly assigned stereotypically African-American-sounding names and stereotypically white-sounding names to otherwise identical resumes to measure discrimination in the labour market.

To examine the role of a criminal record, Pager hired a pair of white men and a pair of black men and instructed them to apply for existing entrylevel jobs in the city of Milwaukee. The men in each pair were matched on a number of dimensions, including physical appearance and self-presentation. As much as possible, the only di↵erence between the two was that Pager randomly varied which individual in the pair would indicate to potential employers that he had a criminal record. Further, each week, the pair alternated which applicant would present himself as an ex-felon. To determine how incarceration and race influence employment chances, she compared callback rates among applicants with and without a criminal background and calculated how those callback rates varied by race.

The names and descriptions of variables in the dataset criminalrecord.csv are:

[Continued on next page]

Table 1: Criminal Record Data




Job ID number


1 if tester received a callback, 0 if the tester did not receive a callback


1 if the tester is black, 0 if the tester is white


1 if the tester has a criminal record, 0 if the tester does not


1 if tester interacted with employer during the job application, 0 if tester does not interact with employer


1 is job is located in the city center, 0 if job is located in the suburbs


Job’s average distance to downtown


1 if job is in the costumer service sector, 0 if it is not


1 if job requires manual skills, 0 if it does not

1.1. Begin by loading the data into R and explore the data. How many cases are there in the data? Show a summary of the data. In how many cases is the tester black? In how many cases is the tester white? What proportion of applicants are black and white? (10 points)

1.2. Now we examine the central question of the study. Calculate the proportion of callbacks for white applicants with and without a criminal record, and calculate this proportion for black applicants with and without a criminal record. (15 points)

1.3. What is the di↵erence in callback rates between individuals with and without a criminal record within each race (i.e. for black and white testers separately). What do these specific results tell us? Consider both the di↵erence in callback rates for records with and without a criminal record and the ratio of callback rates for these two types of records. (15 points)

1.4. Compare the callback rates of whites with a criminal record versus blacks without a criminal record. What do we learn from this comparison? (10 points)

2      Sources of Empathy in the Circuit Courts (50 points)2

In this exercise, you will analyze the relationship between various demographic traits and pro-feminist voting behavior among circuit court judges. In a recent paper, Adam N. Glynn and Maya Sen argue that having a female child causes circuit court judges to make more pro-feminist decisions.

The dataset dbj.csv contains the following variables about individual judges:

Table 2: Judges Data

     Name                               Description

name            The judge’s name

child     The number of children each judge has circuit.1    Which federal circuit the judge serves in

girls           The number of female children the judge has

progressive.vote The proportion of the judge’s votes on women’s issues which were decided in a pro-feminist direction


The judge’s race (1 = white, 2 = African-American, 3 = Hispanic, 4 = Asian-American)


The judge’s religion (1 = Unitarian, 2 = Episcopalian, 3 = Baptist, 4 = Catholic, 5 = Jewish, 7 = Presbyterian, 8 = Protestant, 9 = Congregationalist, 10 = Methodist, 11 = Church of Christ, 16 = Baha’i, 17 = Mormon, 21 = Anglican, 24 =

Lutheran, 99 = unknown)


Takes a value of 1 if the judge was appointed by a Republican president, 0 otherwise. Used as a proxy for the judge’s party


The number of male children the judge has


Takes a value of 1 if the judge is a woman, 0 otherwise


Indicator for the observation number


The year the judge was born

2This exercise is in part based on: Glynn, Adam N., and Maya Sen. (2015). “Identifying Judicial Empathy: Does Having Daughters Cause Judges to Rule for Women’s

Issues?.”           American Journal of Political Science Vol.          59, No.      1, pp.     37–54.    doi:


2.1. Load the dbj.csv file. Find how many judges there are in the dataset, as well as the gender and party composition of our dataset. Is the party composition di↵erent for male and female judges? Additionally, note that our outcome in this exercise will be the proportion of pro-feminist rulings. What is the range of this variable progressive.vote?

(10 points)

2.2. Next, consider the di↵erences between some groups. For each of the four groups (Republican men/women, Democratic men/women) defined by gender and partisanship, create a boxplot (using a single command) that illustrates the di↵erences in progressive.vote. Briefly interpret the results of the analysis. For example, do any of the results surprise you? Does it appear that partisanship, gender, or both contribute to progressive voting patterns? Should we interpret any of these e↵ects causally? Why or why not? (10 points)

2.3. Create a new binary variable which takes a value of 1 if a judge has at least one child (that is, any children at all), 0 otherwise. Then, use this variable to answer the following questions. Are Republicans and Democrats equally likely to be parents (that is, have at least one child)? Do judges with children vote di↵erently than judges without? If so, how are they di↵erent? Do republican and democratic parents vote di↵erently on feminist issues?(10 points)

2.4. The final question explores di↵erences in voting among judges born earlier and judges born later. Create a new binary variable which takes a value of ‘before 1935’ if a judge has is born before 1935, and ‘from 1935’ otherwise. Compare the progressive voting of Republican and Democrat judges separately (a) for those born before 1935 and (b) for those born 1935 or after. Produce two bar plots to show this: one for Republican-appointed judges and one for Democrat-appointed judges. Comment on the similarities and di↵erences between the two charts, in terms of the changes to the progressive voting for judges born earlier and judges born later. (20 points)

Frequently Asked Questions

Is it free to get my assignment evaluated?

Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here.

How much does it cost?

The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):

Regular homework$20 - $150
Advanced homework$100 - $300
Group project or a report$200 - $500
Mid-term or final project$200 - $800
Live exam help$100 - $300
Full thesis$1000 - $3000

How do I pay?

Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.

Why do I need to pay in advance?

We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.

Do you do essays?

No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.

Why there are no discounts?

It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.

Do you do live tutoring?

No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.

What happens if I am not satisfied with the solution?

Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.
