Adv. Stats Workshop: No meeting next week, Wednesday, Nov 26

by adiamond＠fas.harvard.edu

Be advised we will NOT be meeting next week, on Wednesday, November 26. The workshop will resume the following Wednesday, December 3, with a talk by Chris Winship. *************************************** Research Workshop in Applied Statistics *************************************** The Research Workshop in Applied Statistics is a forum for graduate students, faculty, and visiting scholars to present and discuss work in progress and exchange ideas. It is intended as a tour of Harvard's statistical innovations and applications with weekly stops in different disciplines such as economics, epidemiology, medicine, political science, psychology, public policy, public health, sociology and statistics. The topics of papers presented in previous years included missing data, survey analysis, Bayesian simulation, sample selection, and models for election and portfolio choice. Faculty and student participants in the workshop present their current projects, and guest speakers also give occasional presentations. The workshop provides an excellent opportunity for informal interaction between graduate students and faculty from a variety of disciplines. Course credit is available for students as either an upper-level Government or Sociology class. Lunch is provided. If you are interested, note that all events are held at noon, in Room 22, Center for Basic Research in Social Sciences (CBRSS, 34 Kirkland St., this is the yellow building across the street from William James Hall).

Applied Stats Wkshop: Liz Stuart on matching, Wed@noon

by adiamond＠fas.harvard.edu

*************************************** Research Workshop in Applied Statistics *************************************** Please join us this Wednesday @ noon at CBRSS, the Center for Basic Research in the Social Sciences, 34 Kirkland Street, Rm 22, for a presentation by Elizabeth Stuart. Her talk is titled "Matching with Multiple Control Groups". *ABSTRACT* In observational studies, it is desirable to reduce bias due to covariates by obtaining treated and control groups with similar distributions of the covariates. This is often done by choosing well-matched samples of the original treated and control groups. However, sometimes the originally chosen control units cannot provide adequate matches for the treated units. In these cases, it may be desirable to obtain matched controls from two control groups. Multiple control groups have been used in the context of causal inference to test for hidden biases; however, little work has been done on their use in matching or adjustment for these biases. We provide a theoretical basis and practical guidelines for this new approach. The motivating example is a school- wide dropout prevention program where students in the original treated and control schools were significantly different from one another. We consider the use of a second source of control students to supplement the original group. As always, lunch will be provided.

Debra Javeline talk Tuesday, Nov. 18 at 10 AM

by adiamond＠fas.harvard.edu

Professor Debra Javeline, currently a Robert Wood Johnson Health Policy Scholar at CBRSS, invites all Statistical Methods Workshop participants to attend her practice job talk at 10 a.m., Tuesday, Nov. 18, at CBRSS. Her talk is titled, "Judicial Pioneers: Litigants in the Moscow Theater Hostage Case." The research question is what makes citizens decide to challenge governments in courts for the first time (i.e. in postauthoritarian regimes where there is no precedent for government accountability through judicial processes). Her evidence is from a new survey she conducted of former hostages and next-of-kin of deceased hostages. Feel free to email Professor Javeline (javeline(a)latte.harvard.edu) with any questions. The usual lunchtime Statistical Methods Workshop (this week featuring Elizabeth Stuart, on matching methods and causal inference) will take place, as usual, this Wed at noon. An email reminder about Liz's talk will go out later today.

Wed's Applied Stats Wkshop: K. Carman's paper available

by adiamond＠fas.harvard.edu

Katherine Carman's paper "Social Influences and the Private Provision of Public Goods: Evidence from Charitable Contributions in the Workplace" is now available at http://www.courses.fas.harvard.edu/~gov3009/Calendar/carman.pdf Abstract: This paper investigates factors that influence an individuals decision to make voluntary contributions to a public good, focusing on the role of social influences. Measuring social influences is challenging due to several factors: group selection may be based on unobservable tastes, there may unobservable shocks that affect all group members, and the behavior of all group members is determined simultaneously. Proprietary data from the workplace-giving campaign of a large national company are used. These data contain detailed information, which can be used to overcome the difficulties often associated with measuring social influences. This paper formulates the problem of measuring social influences as one of estimating the relationship between individual behavior and the behavior of peers by selecting appropriate instruments for group behavior. The results suggest that individual giving behavior is affected by social influences and that social influences are stronger within salary quartiles and, in some situations, within genders. See you on wednesday, alexis *************************************** Research Workshop in Applied Statistics *************************************** Please join us this Wednesday @ noon at CBRSS, the Center for Basic Research in the Social Sciences, 34 Kirkland Street, Rm 22, for two back-to-back presentations: *Katherine Carman* "Social Influences and the Private Provision of Public Goods: Evidence from Charitable Contributions in the Workplace" Katherine Carman is a Robert Wood Johnson Scholar in Health Policy Research for 2003-2005. She recently completed her Ph.D. in Economics at Stanford. Her primary research interests are in the fields of public economics and health economics. Her past research has examined the role of social influences on charitable contributions, the adequacy of life insurance holdings, and the financial impact of changes in marital status. Followed by *Andrew Leigh* "Who Gets the Earned Income Tax Credit? Impact and Incidence" www.ksg.harvard.edu/students/leighan Abridged abstract: How are hourly wages affected by the Earned Income Tax Credit? Two strategies are utilized. First, I use variation in state EITC supplements and find that a 10 percent increase in the generosity of the EITC is associated with a 4 percent fall in the wages of high school dropouts and a 2 percent fall in the wages of those with only a high school diploma. A second strategy is then implemented, based on the insight that the impact of the EITC on wages is determined by the typical EITC parameters in an employee's labor market. I construct a simulated instrument for the EITC parameters in an employee's labor market, and I find that wages respond to variation in the fraction of eligible employees and the average EITC rate, but do not respond systematically to changes in the marginal EITC rate.
