Trade Networks and Firm Value: Evidence from the U.S.-China Trade War

We study the financial implications of the 2018–2019 U.S.-China trade war for global supply chains. Around the dates when higher tariffs are announced, U.S. firms that depend more on exports to and imports from China experience larger declines in market value, with the negative effect spilling over to the affected firms' suppliers and customers through production networks. The trade war effect is mainly concentrated among U.S. firms that sell to Chinese customers with low R&D intensity or outsource to Chinese differentiated input suppliers. We also exploit the within-firm variation in tariff exposure according to the detailed product lists and conduct a reverse experiment based on the 2019 trade talks. To explain the findings, we propose a theoretical model that highlights how complex trade structures shape shareholder wealth.

What China’s Economic Woes May Mean for the U.S.

“I remain optimistic that the government is still very agile and should be responsive to a potential crisis,” Dr. Tang said. “They know what to do. It’s just a matter of time before they come to some kind of consensus to do something.”

Gig Economy: A Pivotal Element for Economic Transformation

從勞工角度看,平台經濟打破了傳統的僱傭關係。平台企業創造了各種靈活的工作方式,包括常見的社交平台內容創作者、Uber司機、外賣送遞員等等。此類常被稱為「零工」(gig work)的工種,一方面令人感嘆技術為就業帶來方便,但另一方面也常令人擔憂一個大企業壟斷市場,欺壓平台從業員的可能性。

Commercialisation of Intellectual Property Drives High-quality Economic Growth

《十四五規劃綱要》支持香港特區發展八大中心,其中之一是區域知識產權貿易中心。所謂知識產權貿易,到底是指各國企業在港衍生的知識產權及申請的專利,還是連境外的專利也包括在內?香港又可憑哪些優勢和潛力而成為知識產權貿易中心呢?

Hong Kong needs to speed up Trade Modernization

從1990年代以來,很多國家已經嘗試以數碼化方式實現貿易現代化,但受惠於歷時20多年相對平穩的地緣政治環境及高度全球化,貿易數碼化並未得到足夠關注。在新冠疫情期間,全球供應鏈處處受到衝擊,船運、港口與海關操作相繼出現混亂情況。這些深刻經歷過後,各國政府意識到數碼科技可提供靈活及有效的方法,以應對貿易鏈斷裂的問題,因而都在加速推動貿易數碼化。
