Bilateral S-curve between Japan and her trading partners

The cross-correlation function between terms of trade and trade balance has been found to resemble a pattern that is labeled the S-curve. This pattern has received weak support in some developed and less developed countries when aggregate trade data are used. Empirical regularities based on aggregate trade data may be biased since aggregation can potentially suppress some of patterns observed in trade at the bilateral levels. We try to overcome this problem by employing bilateral trade data for Japan and find strong support for the S-curve between Japan and many of her trading partners.
