The following faculty members and PhD students are looking for research assistants this semester. All of these positions are for credit. Students registered for GU4996 will receive either 1 or 2 college credits and be charged for 1 – 2 credits (relevant only to students who pay by the credit). To participate in a faculty research project at no cost, GS students have the option of registering for GU4995 for 1 credit for which they will not be billed. In both cases, students will receive a letter grade on their transcript indicating that they worked as an RA. However, in the case of GU 4995, the 1 credit may not be used to fulfill the minimum credit limit of a Columbia degree. Research positions typically entail 5-7 hours of work per week. Research credit may not be used as a substitute for elective or seminar requirements in the major.

If interested in a position, please contact the researcher directly at the email address provided. If you are selected as the RA then contact me at se5@columbia.edu.

When contacting the researcher regarding a position, you should include a copy of your Columbia transcript (unofficial is ok) and a CV/resume. Additional opportunities may be announced next week.

Belinda Archibong (Professor/Barnard) is looking for assistants to work on two projects.

1. “Colonialists, Taxation and Punishment: Prisons and Labor Coercion in British Colonial West Africa”: We use historical datasets and exploit exogenous changes in commodity prices and labor tax and forced labor regulation from 1914 through 1940 to examine the relationship between labor coercion, colonial fiscal capacity and associated public works expenditures in British colonial West Africa.

Skills needed: Familiarity with Excel is needed. The project requires careful data entry skills and the ability to do basic exploratory data analysis

2. “Firm Culture: Examining the Role of Ethnicity in Hiring Using Evidence from Nigeria”: Africa is the world’s youngest continent, with 60\% of its population below the age of 25 by UN estimates. At the same time, youth unemployment is above 40\% in many countries. While a large literature links ethnic bias to inefficient economic outcomes across a range of contexts in Africa, we have limited understanding of its contribution to frictions in labor markets. We tackle two issues concurrently: high unemployment rates among youth and ethnic bias. Using an online job platform in Nigeria, we study ethnic bias in firm hiring with an audit study and a novel firm and applicant dataset.

Skills needed: Familiarity with Excel is needed. Familiarity with R or Stata is preferred. The project requires careful data entry skills and the ability to do basic exploratory data and statistical analysis.

David Weinstein (Professor) is looking for assistance with two projects.

The first is on measuring the gains and price impacts of e-commerce in Japan. The RA will have to work on cleaning a dataset of regional prices in Japan. The objective of this research is to understand how the entry of e-commerce firms affected pricing in physical stores as well as welfare.

The second project aims understanding the role played by information in Japanese economic development. When Japan opened to international trade in the mid-nineteenth century, it began importing large numbers of books. The project will involve building a dataset on book acquisitions by the National Diet Library to understand how technology flowed into Japan. The student will have to download acquisition information from the web and build a dataset documenting which countries supplied books to Japan and the general subject matter of these books.

Motaz Al-Chanati (PhD student) is looking for an RA for a project to study the impact of pharmaceutical advertising on physician and patient behavior. The first part of the project will involve working with transaction-level data that details payments from pharmaceutical firms to doctors. This is an extremely large dataset consisting of over 50 million records and representing $33 billion in payments. The tasks expected are to clean the dataset, produce data visualization, and analyze patterns across firms/doctors/locations etc. The RA will likely need to do additional research and data collection about pharmaceutical firms and products, so an interest in the healthcare industry may be helpful. Future work on this project can potentially be tailored to the RA’s interest (e.g. structural model estimation, applications of machine learning). This position would be a good fit for someone looking to get hands-on experience with data, especially learning how to process and manage large datasets, as well as those interested in applied micro research or data science. Experience with Python is necessary, while experience with Stata, SQL or GIS software is a plus.

Bhargav Gopal (PhD student) is looking to collaborate with an undergraduate student looking to gain experience in building a project from the ground level. He is exploring two ideas. The first is the effect of non-compete clauses on worker mobility, productivity, and wages. It has been argued that Silicon Valley’s growth has partly been driven by California courts failing to enforce non-compete clauses, and I’d like to investigate if the data backs up this claim. The second project involves crime, and researching whether state level policies designed to reduce crime in one state results in increased crime in neighboring states. Tasks will include reviewing relevant literature in the field, so strong reading skills is a positive. Furthermore, we would also need to collect and analyze data pertaining to the research questions, so statistical programming skills (preferably in R) are also very useful.
