Keynes, Lerner, and the Question of Public Debt
以1943年凯恩斯与勒纳的争论为起点，考察凯恩斯对公共债务的看法，并分析两人思想关系及凯恩斯在1930-40年代的相关评论，指出凯恩斯更谨慎的立场源于其对债务市场心理的关注。
This essay examines Keynes’s views on public debt, taking as its point of departure his 1943 confrontation with Abba Lerner on the issue. It also exhaustively considers the wider intellectual relationship between the two men, as well as Keynes’s other commentaries on public debt in the 1930s and 1940s. The essay concludes that the key issue distinguishing Keynes’s rather more cautious view of feasible and desirable public debt trajectories, vis-à-vis Lerner’s position, is Keynes’s attentiveness to the psychology of the debt markets, which is, in turn, an expression of his sensibility toward theory versus practice.
