How costly is rebalancing away from dependence on uneconomic investment?
Core argument: Japan’s average GDP growth fell from around 5% in the decade before 1991 to under 1% in the decade after, while its share of global GDP fell by nearly half between 1991 and 2008.
Every country that has become excessively dependent on increasingly uneconomic investment has found it difficult to begin an adjustment that its leaders knew was necessary. Japan in the 1980s, Brazil in the 1970s, and the Soviet Union in the 1960s all faced versions of this problem. The Japanese experience shows how costly that adjustment can be. Rebalancing meant for Japan, and means for China, increasing the role of consumption in driving GDP growth, and if an economy cannot rebalance through a sharp increase in consumption growth – and historical precedents suggest that this is extremely unlikely – it must, almost by definition, rebalance through slower growth in production. This is especially difficult when the international competitiveness of manufacturing depends on the same distribution of income that constrains consumption. Raising the role of consumption, in that case, requires raising household income relative to production, but this automatically reduces the cost advantages on which manufacturing depends.
