At the University of Wisconsin-Madison, I worked on a project for Economics 695: Application of Empirical Methods in Microeconomics alongside Shloka Mohanty, Mir Ramisa Raiyan Rose, and Ridhi Mehra.

Our project extended the paper:

"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.

The original study explores whether short-term exposure to PM10 (particulate matter 10 micrometers or smaller) increases pediatric respiratory hospitalizations in São Paulo, Brazil.

Our extension focuses on testing whether alternative weather-related instruments, specifically visibility, UV index, and cloud coverage, can reliably estimate the causal effect of air pollution on pediatric hospitalization rates in Brazil. To do this, we merged the original dataset with additional weather data from the Visual Crossing dataset.
