Distinguished Lecture on Economics in Government: Accounting for Saving and Capital Formation in the United States, 1947–1991
研究了美国经济各部门储蓄与资本形成的来源与去向，通过重新整理国民收入账户数据，得出了与主流观点不同的结论。
This paper is concerned with accounting for the saving and capital formation taking place in different sectors of the U.S. economy. In brief, where does saving arise and where is it used? Do some sectors save more than they spend for capital formation and thus are net lenders? Do other sectors save less than is required for their capital formation and thus are net borrowers? The U.S. national income accounts contain the basic data relating to these questions. However, at several points, these data must be recast in order to yield analytically useful results. When such a reformulation is made, the conclusions that can be drawn differ strikingly from much of the currently received conventional wisdom.
