The gains from catch-up for China and the USA: An empirical framework

As China becomes more closely entwined with the US, positive shocks in the US translate into positive outcomes for China, but the extent of gain for the US during the convergence process is less clear. We develop an empirical framework of two interacting open economies in which Chinese GDP per capita moves towards convergence and cointegration with the US, resulting in a time-varying structural VAR model. As a result, the impulse responses of the two countries to shocks are sensitive to the timing of the shock. The changing e¤ects of US shocks are evident in the analysis, which shows that over the convergence process both the US and China unambiguously bene…t from the catch-up process.
