The article explores whether the increase in value of China's currency, the Renminbi, would help the US reduce its trade deficit. By using a model to simulate different scenarios, the researchers found that the Renminbi's appreciation may not actually lead to a decrease in the US trade deficit with China. This is because of factors like low price sensitivity and high domestic demand for goods in both countries, which slow down the impact of currency changes on trade balances. In simpler terms, just making the Renminbi more valuable might not fix the trade imbalance between China and the US.
