Paths of Development in the Three-Factor, n-Good General Equilibrium Model
用图形和实证检验三要素n种商品模型，用要素三角形表示三维禀赋向量和扩展路径，分析要素回报、产出组合和贸易方向，并用1978年联合国数据提供弱证据。
The three-factor, n-good model is displayed graphically and tested empirically. The three-dimensional endowment vectors and expansion paths are represented by points in an endowment triangle. Features of this endowment triangle determine relative factor returns, Rybczy nski and Stolper-Samuelson derivatives, output mixes, and the directi on of trade. The effects of mobile factors and nontraded goods are al so considered. Capital accumulation is shown to induce changes in out puts, trade, and the returns to factors that depend on the abundance of land relative to labor. Weak evidence for this 3 A n model is foun d in a 1978 U.N. data set on the value of output. Copyright 1987 by University of Chicago Press.
