Profitability and Growth in Multiregion Systems: Theory and a Model
构建了一个摒弃均衡概念的多区域动态模型，分析盈利性、资本投资与价值在区域间的变化，发现资本净流动不一定指向高利润区域，且利润率轨迹受需求、供给、资本增长率及贸易投资政策影响。
Interpretations of geographic changes in production over the last 20 years have themselves drawn upon theories of global economic change. In turn those theories rely upon models of economic dynamics that rest upon unduly restrictive notions of equilibrium and that ignore space and region. This paper therefore explains a multiregion dynamic model of profitability, capital investment, and value that eschews notions of equilibrium. The model, even in its general form, demonstrates that values are spatially variable; that net flows of capital occur between regions even if rates of profit are equal; that net flows of capital do not necessarily point to higher profit locations; and that the trajectory of rates of profit depends not only upon the traditional notions of organic composition and rate of exploitation but also upon the rates of growth of demand, supply, and capital, as well as upon trade and investment policies. The next stage of this research is to use empirical observation to estimate the parameters of the model so as to illustrate its usefulness in interpreting the historical geography of production in the OECD.
