题目: The economics of travel bubbles: why they did not work?
主讲人：王姣（University of Melbourne）
讲座内容：We use a multi-region Susceptible-Infected-Recovered-Macroeconomic (SIR-Macro) model to evaluate cooperative cross-border travel arrangements during a pandemic, sometimes known as travel bubbles, from a game theory perspective. The Pareto optimal emphasizes domestic containment, but policymakers are always incentivized not to commit to cooperation. An attempt to deviate from the cooperative policies results in a negative externality in the partner region. This non-cooperative outcome features long-run travel restrictions with fewer economic or health benefits. The model is then applied to assess the Singapore-Hong Kong travel bubble, which was eventually aborted. The travel bubble would have delivered the highest welfare, but without it, Singapore and Hong Kong would still achieve smaller welfare gains with effective domestic containments. We also find that pre-departure tests would not improve welfare from cooperation and that quick vaccination programs would be essential to bring the economies back to normal.
