Here’s good news about the economics profession — for the development community and for us at CGD.
Skilled people from developing countries are increasingly migrating to other countries. How should policy respond?
International migration has giant effects on global development. Social scientists are just starting to understand those effects, and the latest research is moving far beyond traditional subjects like remittances.
In Milan Kundera’s The Unbearable Lightness of Being, Sabina and Franz are doomed lovers. Kundera traces their demise of their relationship to a disagreement about what words mean. Sabina and Franz never realize that they mean different things when they say simple words—like “woman” and “truth.”
The welcome rise of replication tests in economics has not been accompanied by a single, clear definition of ‘replication’. A discrepant replication, in current usage of the term, can signal anything from an unremarkable disagreement over methods to scientific incompetence or misconduct. This paper proposes an unambiguous definition of replication, one that reflects currently common but unstandardized use. It contrasts this definition with decades of unsuccessful attempts to standardize terminology, and argues that many prominent results described as replication tests should not be described as such. Adopting this definition can improve incentives for researchers, encouraging more and better replication tests.
