Quality, Trade and the Moving Window: The Globalisation Process
构建了一个企业生产率和质量存在差异的模型，分析全球化进程。贸易自由化使可销售的质量区间上移（“移动窗口”），初始阶段可能降低中等能力国家的福利，但后续能力转移时这些国家可能获益最大。
The globalisation process is analysed in a model where firms differ in productivity and quality. A lower bound to quality emerges, below which firms cannot sell, however low their (local) wage rate. The range of quality levels between the maximum and this lower bound shifts upwards when trade is liberalised (the 'moving window'). The initial phase of globalisation, associated with trade liberalisation, in an initially segmented (but not autarkic) world, may reduce welfare in countries with intermediate levels of capability, but these countries may be the most important gainers as capabilities are transferred in subsequent phases.
