Patrick researches in three areas. First, he tries to quantify discrimination in labor markets. He is currently working on field experiments that quantify hiring discrimination faced by older workers and Indigenous Peoples.
Second, in addition to quantifying discrimination, he also studies if age and disability discrimination laws actually reduce employment discrimination. He is currently working on a project funded by the National Bureau of Economic Research that investigates how changes to the Americans with Disabilities Act have affected employment and earnings of individuals with disabilities.
Third, he studies how tax incentives for economic development affect where firms operate, using tax incentives for the film industry as a case study.
