In order to pursue ‘fair trade’, the Trump administration has imposed a punitive 25% tariff on $250 billion’s worth of Chinese goods. However, conventional trade statistics greatly exaggerate the US trade deficit with China. This column uses the iPhone as an example to demonstrate how the trade deficit is inflated and why value-added should be used to assess the bilateral trade balance. If multinational enterprises, including Apple, shift part of their value chains out of China, China may no longer play a central role in global value chains targeting the US market. Depreciation of the yuan will be insufficient to counter the effect.

As the trade surpluses of East Asian countries have continued to exist in regional value chains despite the US-China trade war, one possible tool such economies could employ are currency appreciations. This column shows how exchange rates in upstream countries affect China’s exports. No single economy wants to appreciate its currency against the US dollar for fear of losing competitiveness, but a concerted effort to prioritise regional currencies could benefit the set of countries as a whole.

Japanese exports in electronic parts and components dramatically fell in value after the Global Crisis and have not recovered until today. This column investigates why Japan lost this comparative advantage. It argues that capital inflows seeking safe havens during the crisis led to a sharp appreciation of the yen and caused yen export prices to tumble relative to production costs. Plummeting profits then hindered Japanese firms from investing enough in capital and innovation to compete with rivals.

This column introduces a model in which delayed portfolio adjustment by investors can address six such puzzles of exchange rate movements. The findings show that slowness in the reactions of investors has the potential to influence asset prices.

Many policymakers are concerned that fast trading has adverse effects on markets, although the existing evidence is ambiguous. This column argues that high-frequency trading can increase market efficiency and the quality of trade. By creating noise, fast trades may prevent traders with a herd mentality from pushing prices in one direction.
