Previous research has shown that women in the treatment group of the CeMENT randomized controlled trial increased their publications and the likelihood that they were tenured in top-50 economics departments. This paper examines one potential mechanism, na...

Field Specializations among Beginning Economists: Are There Gender Differences?

By Eva Sierminska and Ronald L. Oaxaca

AEA Papers and Proceedings, May 2021

We examine the process underlying field specialization among beginning economists. Our multivariate logit framework accommodates single- and dual-field specializations with correlated choices. Including field-specific relative salaries and expected probab...

"Placebo Tests" for the Impacts of Air Pollution on Health: The Challenge of Limited Health Care Infrastructure

By Bruna Guidetti, Paula Pereda, and Edson Severnini

AEA Papers and Proceedings, May 2021

"Placebo tests" are normally used to support evidence of pollution impacts on health outcomes. In this study, we argue that one should be cautious to proceed with falsification tests. We examine how a large metropolitan area in Brazil copes with increased...

Ambiguous Air Pollution Effects of China's COVID-19 Lock-Down

By Douglas Almond, Xinming Du, Valerie J. Karplus, and Shuang Zhang

AEA Papers and Proceedings, May 2021

Reductions in ambient pollution have been suggested as a "silver lining" to the COVID-19 pandemic. We analyze China's pollution monitor data and account for the large annual improvements in air quality following the Lunar New Year, which essentially coinc...

Environmental Protection or Environmental Protectionism? Evidence from Tail Pipe Emission Standards in China

By Jie Bai, Shanjun Li, Danxia Xie, and Hui Zhou

AEA Papers and Proceedings, May 2021

Under the stated goal of improving air quality, many cities in China restricted the import of used vehicles from other cities based on tail pipe emission standards. Using detailed data on new and used vehicle registration, we examine the impact of the pol...

The Health Impacts of Coal-Fired Power Plants in India and the Co-benefits of Greenhouse Gas Reductions

By Maureen Cropper, Ryna Cui, Sarath Guttikunda, Nate Hultman, Puja Jawahar, Yongjoon Park, Xinlu Yao, and Xiaopeng Song

AEA Papers and Proceedings, May 2021

Under the Paris Agreement, India has pledged that 40 percent of its electricity generating capacity will come from non-fossil-fuel sources by the year 2030; however, this pledge does not limit total coal-fired generating capacity. As of 2019, planned incr...

Inference for Support Vector Regression under ℓ₁ Regularization

By Yuehao Bai, Hung Ho, Guillaume A. Pouliot, and Joshua Shea

AEA Papers and Proceedings, May 2021

We provide large-sample distribution theory for support vector regression (SVR) with ℓ1-norm along with error bars for the SVR regression coefficients. Although a classical Wald confidence interval obtains from our theory, its implementation ...

The Proximal Bootstrap for Finite-Dimensional Regularized Estimators

By Jessie Li

AEA Papers and Proceedings, May 2021

We propose a proximal bootstrap that can consistently estimate the limiting distribution of √n consistent estimators with nonstandard asymptotic distributions in a computationally efficient manner by formulating the proximal bootstrap estimator as the s...

Adversarial Inference Is Efficient

By Tetsuya Kaji, Elena Manresa, and Guillaume A. Pouliot

AEA Papers and Proceedings, May 2021

We study properties of the adversarial framework, introduced in Kaji, Manresa and Pouliot (2020). We show that the adversarial inference with an oracle classifier is statistically efficient. In addition, we study the finite sample properties of the advers...

Estimation and Inference by Stochastic Optimization: Three Examples

By Jean-Jacques Forneron and Serena Ng

AEA Papers and Proceedings, May 2021

This paper illustrates two algorithms designed in Forneron and Ng (2020): the resampled Newton-Raphson (rNR) and resampled quasi-Newton (rQN) algorithms, which speed up estimation and bootstrap inference for structural models. An empirical application to ...

Union Reform, Performance Pay, and New Teacher Supply: Evidence from Wisconsin's Act 10

By E. Jason Baron

AEA Papers and Proceedings, May 2021

This study examines the impact of performance pay on teacher selection. I exploit a shift toward performance pay in Wisconsin induced by the enactment of Act 10, which gave school districts autonomy to redesign their compensation schemes. Following the la...

School Capital Expenditure Rules and Distribution

By Barbara Biasi, Julien Lafortune, and David Schönholzer

AEA Papers and Proceedings, May 2021

We provide descriptive evidence on the level and within-state distribution of school capital expenditures over the past two decades. We relate these to the fiscal institutions governing capital funding across states. Within-state differences in capital ex...

Test-Based Accountability and the Effectiveness of School Finance Reforms

By Christian Buerger, Seung Hyeong Lee, and John D. Singleton

AEA Papers and Proceedings, May 2021

A recent literature provides new evidence that school resources are important for student outcomes. This paper examines whether school accountability systems that incentivize performance (such as No Child Left Behind) raise the efficiency with which addit...

The Common Application and Student Choice

By Brian Knight and Nathan Schiff

AEA Papers and Proceedings, May 2021

We study the effects of the Common Application (CA) platform, which allows students to submit a single application to multiple institutions, on student choice. Using individual-level data from freshman surveys over the period 1982–2014, we develop two p...

Microcommitments: The Effect of Small Commitments on Student Success

By Amanda J. Felkey, Eva Dziadula, Eric P. Chiang, and Jose Vazquez
