Currency Invoicing in Japanese Exports to East Asia: Implications for Yen Internationalization

摘要

The present paper examines currency invoicing in Japanese exports to East Asia by applying the pricing-to-market (PTM) theory. The notable aims of the present paper are to: (i) use a number of sample commodities obtained from the data on monthly series of exports based on the nine-digit Harmonized System; and (ii) examine currency invoicing practices of Japanese exporters by making a distinction between the long-run and short-run PTM under the framework of the error-correction model. Contrary to the results of previous reports, our study shows that Japanese exporters of electric machinery tend to stabilize US Dollar (USD)-denominated export prices in the short run in East Asian markets, implying that electric machinery products tend to be invoiced in USD in exports to East Asia. Given the USD-invoicing practices by Japanese electric machinery exporters, it is hard to expect the further use of the Yen in trade transactions because the electric machinery industry plays a major role in facilitating trade and investment between Japan and East Asia.
