Overview: The 2019 DRI Annual Conference focused on the theme “From Local to Global: The External Validity Challenge of Experiments.” In recent decades, the use of experimental and quasi-experimental methods has become widespread across a range of fields in economics, such as labor, education, health, and especially development. The emphasis on experimental and quasi- experimental methods was driven by an attempt to generate internally valid results, i.e., accurate estimates of the impact of the policy of interest in the time and place the experiment was implemented. But the now global scale of experiments points to the central question of external validity: to what extent and how can we generalize the knowledge generated by experiments beyond the setting of the experiment to other contexts? 

A group of ten people stand on a wooden stage in front of a screen displaying 2019 DRI Annual Conference. They are posing together and smiling, dressed in business or business casual attire.

Two people stand at separate podiums on a stage, speaking into microphones. Both are smiling. Behind them are banners with the text Development Research Institute. A red curtain hangs in the background.

A large audience sits in an auditorium facing a stage with red curtains, where a person is giving a presentation in front of a screen displaying slides. The photo is viewed from the back of the room.
