我们开发了一个新的框架，从微观到宏观的贸易模式。我们得出的价格指数决定了国家和部门的比较优势以及总生活成本。如果企业和产品是不完美的替代品，我们表明，这些价格指数取决于品种，平均需求/质量和分散的需求/质量调整价格，只有弱相关的平均价格的标准经验措施，从而提供洞察力的弹性难题。在比较优势的横截面（时间序列）变化中，50%（90%）是由品种和平均需求/质量造成的，平均价格的贡献不到10%。
We develop a new framework for aggregating from micro to macro patterns of trade. We derive price indexes that determine comparative advantage across countries and sectors and the aggregate cost of living. If firms and products are imperfect substitutes, we show that these price indexes depend on variety, average demand/quality and the dispersion of demand/quality-adjusted prices, and are only weakly related to standard empirical measures of average prices, thereby providing insight for elasticity puzzles. Of the cross-section (time-series) variation in comparative advantage, 50 (90) percent is accounted for by variety and average demand/quality, with average prices contributing less than 10 percent.
