Over at VoxEU.org , Kyoji Fukao and Tangjun Yuan of Hitotsubashi University in Tokyo have an interesting analysis of Japan's particular economic woes. As they point out, the Global Economic Crisis hit Japan especially hard. Its GDP contracted at a rate nearly twice that of the US in the last quarter of 2008. And yet it did not have a bursting housing bubble or a toxic assets problem on anywhere near the scale as the US and Europe. So why is it struggling, it seems, worse than most? The answer, Fukao and Yuan find, is in Japan's "triangular trade" model. Japan's economic strength is dependent on exports to the West--in large part, the US. But it is also dependent on exports to other Asian countries: Until the economic crisis, there was vigorous “triangular trade”, in which the advanced economies of Asia, such as Japan, South Korea, and Taiwan, exported key components to developing countries, such as China, Thailand, or Vietnam, which assembled and exported the final products to the US (and Europe) in return for US Treasuries. The Asian developing countries specialised in relatively low value-added assembly and manufacturing processes, while the advanced countries concentrated on high-value added processes, such as the production of key components. However, the sudden decrease in US imports has very rapidly contracted this triangular trade. US goods imports fell during the last quarter of 2008 at an annual rate of 19.6%. And as developing countries’ exports to the US decreased, so did their imports from Asia’s advanced economies. Japan, South Korea, and Taiwan thus suffered a significant decline in exports. Of course, Japan is not alone in using this model. China does as well. But while China is taking a bigger hit in terms of net exports, its GDP is not contracting at as fast a rate. Fukao and Yuan: Finally, Figures 4 and 5 compare the impact on gross output and GDP, respectively, for the Asian countries. Reflecting the large decrease in exports, the drop in China’s gross output is 1.7 times as large as Japan’s. However, the difference in the impact on GDP is considerably smaller; the decrease in China’s GDP is only 1.3 times as large as Japan’s. This situation is also the result of triangular trade. China is relatively specialised in the processing and assembly of imported intermediate goods using cheap labour, and the products are then exported to the US. However, the value added ratio of this kind of production is typically low, and it is for this reason that the decrease in GDP is smaller than the decrease in gross output. Read the full post here .
