In this dissertation, I present three papers on labor economics. The first chapter, Right to Work Laws and Total Worker Compensation: Evidence from Difference-in-Differences and Synthetic Control, examines Right to Work (RTW) laws and their corresponding labor market outcomes. To explore this relationship, I use Current Population Survey (CPS) data and difference-in-differences (DD) and synthetic control methodologies. I find some evidence that RTW laws reduce union membership after about four years and there is a small decrease in unemployment in the private sector. RTW laws lower hourly wages and unemployment in highly unionized industries, particularly decreasing wages for workers in the construction, manufacturing, mining, and medical industries. I also find that RTW laws reduce wages in mid-size firms with less than 500 employees. Finally, there is evidence that wages only decline in Oklahoma and Indiana. The second chapter, The Effects of Charter School Entry on the Supply of Teachers from University-Based Education Programs, (co-authored with Douglas Harris) focuses on school district-level policies and how charter schools impact the local teacher labor market. We use a DD methodology to compare the proportion of teacher preparation education degrees in districts with and without charter schools, before and after charter entry. We find that charter entry reduces the teacher supply in districts with charter schools. We then show that this reduction is concentrated in urban districts but may increase the teacher supply in rural areas. In the final chapter, Do Stronger Employment Discrimination Protections Decrease Reliance on Social Security Disability Insurance? Evidence from the U.S. Social Security Reforms, (co-authored with Patrick Button and Mashfiqur Khan), we study how state disability and age discrimination in employment laws that are stronger or broader than federal discrimination laws impact employment and Social Security Disability Insurance (SSDI) applications and receipts. Using a DD model, we find that some state discrimination laws, like a broader definition of disability and higher damage limits, reduce SSDI applications and receipts. We also find this primarily affects older men.
