Predictions and projections

November 20, 2019 - 17:19 -- Admin

I have a piece in The Conversation arguing against the common practice of publishing projections, based on holding constant parameters that are unlikely to remain so in practice. I suggest modellers need to bite the bullet, make predictions and stand by them.

A slight clarification, arising from discussion. To the extent that we are concerned with policy, it’s fine to make conditional predictions about the consequences of alternative policy packages.
