The Hopkins Health, Labor, Education, and Development Economics Conference (H2LED) is organized by professors from Johns Hopkins University’s Bloomberg School of Public Health, Carey Business School, and Krieger School of Arts and Sciences.

The aim of the conference is to bring together academic economists from different divisions around Johns Hopkins University, open lines of communication, foster collaboration across schools, and showcase the diverse research projects of Johns Hopkins economists.

Presentations will not only showcase cutting-edge economic research but also highlight the diverse sets of methods and approaches used by economists to answer vital research questions to generate research that might help shape policies regarding education, health, development, and labor.
