- Thursday's Human Resources Workshop: Nicole Caviris, Iowa State University
"Measuring the relative contributions of college attainment, changing majors, and narrowing wage differences within majors to narrowing gender wage gaps 1966-2011," with Nicole Caviris, Iowa State University, Thursday Dec 12, 2013 3:40 pm - 5:00 pm, 360 Heady Hall.
Abstract: Pay gaps between men and women have narrowed since 1970. There have been many explanations offered for this decline, but the most important have been the increased likelihood that women complete college, a narrowing of the gender differences in occupational choice, and a reduction in wage discrimination. Changes in relative wages between men and women over time can be decomposed into changes within college majors versus changes between college majors. This study estimates the contributions of college entry, major choice and pay differentials within occupations on the overall decline in gender pay gaps from 1966 to 2011. This paper provides an analysis of pay gaps for college graduates using a Tornqvist approximation to a shift-share analysis of the factors affecting relative earnings for men and women.

"Theory and Practice of Inference in Regression Discontinuity: A Fixed-Bandwidth Asymptotics Approach," with Otavio Bartalotti, Tulane University, Thursday, December 12, 3:40 PM-5 PM, 368A Heady Hall.
Otavio Bartalotti is an assistant professor of economics at Tulane University. The focus of his work is on economic theory, applied econometrics, labor economics and education economics. He received both his MS and PhD in economics from Michigan State University.
Abstract: In regression discontinuity design (RD), researchers use bandwidths around the discontinuity. For a given bandwidth, one can estimate asymptotic variance based on the assumption that the bandwidth shrinks to zero as sample size increases (the traditional approach) or, alternatively, that the bandwidth is fi xed. The main theoretical results for RD rely on the former, while most applications in the literature treat the estimates as parametric. This paper develops the " fixed-bandwidth" alternative asymptotic theory for local polynomial estimators, bridging the gap between theorists and practitioners and shedding light on implicit assumptions on both approaches. The fixed-bandwidth approach provides alternative formulas, i.e. alternative approximations, for the bias and variance of RD estimators. Simulations indicate that fixed-bandwidth approximations are usually better than traditional approximations, and improvements are nontrivial when there is heteroskedasticity. When there is no heteroskedasticity, both approximations are shown to be equivalent under some additional mild conditions. Feasible estimators of fi xed-bandwidth standard errors are easy to implement and improve coverage of con fidence intervals compared to the traditional approach, especially in the presence of heteroskedasticity. Fixed-bandwidth approximations are akin to treating RD estimators as locally parametric, providing theoretical justifi cation for the common empirical practice of using heteroskedasticity-robust standard errors in RD settings.
Graduate Student Announcements
- CELT Spring Semester Teaching Assistant Seminar
All TAs who are new to the ISU classroom, or who have received a teaching assignment different from what they have done before, are strongly encouraged to attend this seminar. Discussion will focus on topics such as classroom management, effective grading, and preparing for the first day of class. Ideas for specific types of teaching, time management, and working with students will also be shared. Help us welcome your new TAs to the ISU classroom!
