本研究結合國際貿易量化運算以及流行病學模型，試圖在健康與經濟之間權衡，在開放經濟體中，計算出最佳的防疫政策。如同圖表所示，在沒有國際貿易的幫助下，各國的防疫政策需要更加緊縮；但是在各國可以互通有無的情形下，防疫政策可以適當放鬆。在不影響人民健康的狀況下，這樣可以達到更高的經濟產出，使全球的人民福祉上升。
This study combines quantitative analysis of international trade and epidemiological models to balance health and economic considerations. In open economies, it aims to calculate the optimal pandemic containment policies. As shown in the chart, without the aid of international trade, countries need to implement stricter containment policies. However, with international trade, these policies can be appropriately relaxed, achieving higher economic output without greatly compromising public health, thereby enhancing global welfare.
