Stata screencast on model validation using graphs

The fourth episode of my Stata screencasts are now available at Vimeo. This episode looks at how to examine the homoskedasticity and normality assumptions using graphs. It also covers how to export graphs from Stata using menus or do-files. You can find it using the link above or simply by using the embedded video below.

Well – it was bound to happen at one point!

I finally caved and got myself a twitter account. You can see my tweets on the right or you can follow me by using this link:

New version of paper on the causal effects of dropping out of high school

Mark Anderson and I just finished revising our paper on high school dropouts and sexually transmitted infections. It has a new title: “High School Dropouts and Sexually Transmitted Infections”. You can find the new version here.

People who drop out of high school fare worse in many aspects of life. We analyze whether there is an effect of dropping out of high school on the probability of contracting a sexually transmitted infection (STI). Previous studies on the relationship between dropout status and sexual outcomes have not empirically addressed self-selection effects. Using individual fixed effects estimations we find strong evidence that dropping out increases the risk of contracting an STI for females. Furthermore, we present evidence that illustrates differences between the romantic partners of dropouts versus enrolled students. These differences suggest that female dropouts may be more susceptible to contracting STIs because they partner with significantly different types of people than non-dropouts. Our results point to a previously undocumented benefit of encouraging those at risk of dropping out to stay in school longer.

Shamma Alam named 2012 Hewlett Foundation / IIE Dissertation Fellow

Shamma Alam has been named as one of the seven 2012 Hewlett Foundation / IIE Dissertation Fellows. These fellowships support dissertation research on topics that examine how population dynamics, family planning and reproductive health influence economic development, including economic growth, poverty reduction, and equity. Shamma and I are currently working on a paper examining the effects of income shocks on timing of fertility and use of contraceptives in Tanzania. Shamma has also worked as my RA on my NSF grant. The official announcement and short bio of Shamma and the other recipients is here.

International Development Internship Program (IDIP) at Seattle University

This announcement from Joe Philips, Dean of Albers School of Business and Economics, is mainly of interest for students at Seattle University:

We are pleased to announce that the university’s International Development Internship Program (IDIP) will become part of the Albers School starting this academic year. Dr. Janet Quillian, who has directed the program since it started in 2001, will be joining the Albers School as part of our faculty, having served on the SU faculty since 1995. Janet’s disciplinary background is in nursing, with her undergraduate degree from the University of Nevada, master’s from Texas Women’s University, and doctorate from the University of Texas.

If you are not already familiar with IDIP, it is truly one of the most distinctive programs at SU, offering undergraduate students from across the campus an opportunity to work with an NGO in emerging economies in Africa, Latin America, and Asia. A brief description of the program on the program website says:

The International Development Internship Program (IDIP) is a 20 credit, three-phase academic program designed for undergraduate students. Students are challenged to explore the root causes and consequences of situations that undermine the well-being of individuals in the developing world. The goal of the IDIP Program is to instill in students a lifelong commitment to the Jesuit mission of service and promotion of social justice. Internships with non-governmental organizations (NGOs) are available in Asia, Africa and Latin America.

For more information on IDIP, check out the current website:

Family planning paper mentioned in Chicago Policy Review

This came out a little while ago, but has a nice summary of my work with Kathleen Beegle and Luc Christiaensen on the effectiveness of family planning programs in Ethiopia. You can read the post here.

Visit to Bergen

I was in Bergen in June and presented my work with Kathleen Beegle and Luc Christiaensen on the effects of family planning on fertility at CMI and my work with Shamma Alam on income shocks and timing of fertility at Norwegian School of Economics. A new version of the family planning paper will be available soon and we should have the first public version of the timing of fertility paper ready soon as well.
