AI 中文总结
本文将ANTONIADES模型扩展为多国多部门框架，估计发现富国质量偏好更强，模拟显示质量偏好和技术差异影响贸易收益，普遍提质量偏好时大国获益更多。
AI 中文摘要
本文研究各国在质量偏好强度和质量提升技术上的差异程度，并量化这些差异对各国贸易收益差异的贡献。本文采用ANTONIADES模型，该模型允许企业进行内生质量选择，并将该框架扩展为多国多部门设定，新特征是双边贸易自由化会对另一国的竞争力产生溢出效应。本文在多国多部门框架下对模型进行结构估计，发现较富裕国家通常对质量的估值更高。量化结果表明，各国质量偏好强度和质量提升技术的差异会加剧其市场竞争力的异质性。随后，本文模拟了贸易壁垒提高5%的情况，若关闭质量渠道，质量偏好较强的国家会在贸易壁垒损失上出现更大程度的低估。最后，普遍提高质量偏好带来的收益在各国间并不均等，较大经济体通常比较小经济体获得更多收益。
英文摘要
In this paper, I study to what extent countries differ in their preferences for quality and their technologies for improving quality. The paper also quantifies the contribution of those differences to the differences in gains from trade across countries. I adopt ANTONIADES, which allows endogenous quality choice of firms. This paper extends that framework into multi-country and multi-sector setting. The new feature is that bilateral trade liberalization yields spillover effects on the competitiveness of another country. This paper structurally estimates the model under multi-country and multi-sector framework. It is found that richer countries generally have stronger valuation for quality. The quantification demonstrates that variations in the strength of quality preferences and in the technology of improving quality across countries add to their heterogeneities in market competitiveness. Subsequently, I simulate a 5% increase in the trade barriers. If the quality channel is shut down, countries with stronger preferences for quality have larger degrees of underestimations in their losses from the trade barrier. Finally, gains from a universal rise in quality preference are unequal among countries, with larger economies generally gaining more than smaller economies.
