Some comments from myself on Brian's retirement:
I do want to highlight just one major intellectual impact of Brian's work. For a long time in the economics community, inequality was viewed as a kind of state of nature, a natural outcome of market forces. Our late colleague Sir Tony Atkinson once said that prominent economists used to tell him that inequality is ‘not an economic problem’.
It might be a social problem, or a political problem, but not an economic problem; and that distributional outcomes simply reflect market forces at work.
What Brian’s more than a decade of very careful, rigorous, comparative work has conclusively shown is that inequality is not just a natural outcome of market forces, it is a choice. That countries facing very similar technological, trade, and other economic forces can have very different distributional outcomes depending on their policies, how they structure their labour markets, and other institutional choices that shape their economies.
