“Once upon a time there was a field called development economics”—by this Paul Krugman started his review article on development economics a quarter century ago. “That field no longer exists,” he also added. The 1940s and 1950s were the eras of “high development theory” when development economics became one of the top fields in economics armed with a distinctive set of new ideas stressing pecuniary externalities arising from increasing returns technologies and imperfect market competition.
