The Relative Price of Non‐traded Goods under Imperfect Competition*
在Balassa-Samuelson框架下引入不完全竞争，研究非贸易品与贸易品的相对价格如何受生产率和加成率差异影响，并用12个OECD国家的行业面板数据验证了该假说。
Abstract We consider the role of imperfect competition in explaining the relative price of non‐traded to traded goods within the Balassa–Samuelson framework. Under imperfect competition in these two sectors, relative prices depend on both productivity and mark‐up differentials. We test this hypothesis using a panel of sectors for 12 OECD countries. The empirical evidence suggests that relative price movements are well explained by productivity and mark‐up differentials.
