‘Capital in the 21st century’ has had an extraordinary – and extraordinarily rapid – impact on the global economic dialogue. It has drawn an extraordinary – and extraordinarily rapid – response, including a front-page critique by an FT journalist. In this column, the book’s author responds point-by-point to the critiques. He rejects the notion that he made outright mistakes. Scholars working with old data make judgments and compromises to expand the dataset; disagreements are inevitable – a point that applies equally to the journalist’s ‘corrections’. In any case, the book’s overall analysis is robust to such critiques.
