The U.S., Tariffs, and Trump

In the highly anticipated US presidential election, regardless of the outcome, the elected candidate will significantly impact the international political and economic landscape. Trump’s foreign economic policy during his first term has already become apparent, with a strong focus on using tariffs as a negotiation tool. If re-elected, he intends to impose tariffs of up…


Coming under the global spotlight, the recent US presidential election was so closely contested that nationwide election polls showed Donald Trump and Kamala Harris in a dead heat with each other. At the time of writing this article, neither candidate managed to hold a lead beyond the margin of error. Under the influence of various factors, the accuracy of the public polls is questionable. After all, both the prediction of a victory for Hillary Clinton in the 2016 presidential election and the forecast of a landslide victory for the Republicans in a “red wave” in the 2022 mid-term elections failed to materialize. However, regardless of who wins the election, the international political and economic landscape is bound to undergo some serious changes as a result, especially if the often-considered “maverick” Trump comes to power.

Trump’s foreign economic policy approach was made quite clear in his first term as president with the slogan “Make America Great Again”. Concrete measures include rejection of win-win cooperation, withdrawal from multilateral agreements, targeting trading partners with trade surpluses against the US, and using tariffs as a main weapon. In his comeback this time, he has reiterated multiple times that, if elected, he will impose higher tariffs on imports from all countries. The tariff rates on Chinese imports will be between 60% and 100% or even higher, while those on imports from other countries will be as high as 10% to 20%.

Protectionism from the founding of the US to WWII

Tariffs are Trump’s favourite weapon in international negotiations to threaten other countries into submission. When he initiated the trade war in 2018, he arbitrarily used national security as a pretext to impose massive tariffs on imports from European Union and China. He even bragged, “I am a tariff man”, believing that “trade wars are good, and easy to win”. While delivering a stump speech at a rally in Chicago about two weeks ago, he said, “Tariff is the most beautiful word.” On another occasion, he boasted that tariffs could serve to fight for peace. In the event of a war between two countries, he claimed he could call both sides and warn them that if their conflict continues, America will levy tariffs on them, which would naturally bring an end to the war.

Trump’s obsession with tariffs suggests that he regards the tool as a virtual panacea for all foreign economic affairs. This may be attributed to different reasons or complexes. First, on the face of it, from his perspective as a businessman, getting goods out the door is a good thing. Otherwise, it is a bad thing. Likewise, a trade deficit is a problem for the US, and since tariffs can deal a blow to the sales of the importing country, of course it is a good policy. Second, whether intentional or not, Trump erroneously insists that the increased tariffs are borne by foreign countries rather than by American consumers. Since imposing the tariffs can also serve to lighten the burden of taxes on American companies and individuals, why not proceed with it?

On a deeper level, tariffs, as an indispensable external economic tool, have a long history in America. Trump’s views and policies about tariffs apparently echo historical precedents. During the Second World War, the US took the lead in establishing the global economic order. In the name of free trade, it called on other economies to open up their markets, as if free trade had always been the national policy and philosophy of America. On the contrary, from its founding to the Second World War, the country had been highly protectionist, with tariffs as the essential tool for its policy implementation.

Since the founding of America, the government’s role in economic development has been subject to change and debate. Even so, the fundamental approach has consistently been for the government to drive economic development with a visible hand.

While the American economy was largely agriculture-based and its economic strength paled in comparison to the UK, the nation regarded the latter as its chief competitive rival. Rejecting the free trade advocacy of the UK at the time, the US relied on high tariff rates to protect and develop its own industry and allocated government subsidies to build its infrastructure in a bid to catch up with the UK. This sentiment grew much stronger when the two countries went to war again in 1812.

A boon to social harmony and economic development

The high regard the US places on levies is evident in its high tariffs over the years. Calculating only the imports subject to tariffs, the average tariff rate during the 1820s once reached a staggering 60% and still hovered between 40% and 50% in the second half of the 19th century. Even including imports unaffected by tariffs, the average tariff rate throughout the 19th century was 30%. By the early 20th century, despite having undergone a downward adjustment, the average US tariff rate rose back to approximately 60% after the Smoot-Hawley Tariff Act was passed during the Great Depression of the 1930s. Hefty tariffs led to retaliation from trading partners and such mutually destructive practices are regarded as one of the reasons for the world economy’s predicament during the Great Depression.

Apart from protecting domestic industrial development, steep tariffs were also a main source of income for the US government. While high tariffs do not necessarily lead to increased revenue, they did account for 90% or more of state coffers in various fiscal years during the 19th century.

During the decades between 1870 and 1910, the average US tariff rate was as high as 50%. Such a high share of tariffs in fiscal revenue can primarily be attributed to the absence of income taxes. While a form of income taxes existed during the Civil War, the US business income tax and personal income tax, as we know them today, were introduced by legislation later in 1909 and 1913 respectively. After that, tariffs became much less important fiscally. Nevertheless, for over 100 years before 1913, tariff income afforded the US government significant fiscal space to maintain social harmony and facilitate economic advancements. Although there is considerable controversy surrounding the extent to which tariffs and protectionism have promoted US industrial and economic development, the long-standing and prominent presence of tariffs makes it more readily acceptable to Americans.

That being said, tariffs as a type of tax have a clear problem in that they are inherently regressive rather than progressive, unlike income taxes, which are a common form of taxation nowadays. Everyone, rich or poor, pays the same levy rate when buying the same product. In contrast, the tax as a share of income is lower for the rich than for the poor. This means that the tax rate is relatively lower for higher-income earners, thus contravening the principle of fair taxation in the eyes of many.

All these considerations, though not the principal cause of the American Civil War, do reflect certain conditions in the country. Although the South had a lower income than the North, it paid the same amount of import tariffs. In fact the industrial sector protected by these tariffs was chiefly located in the North.

By the early 20th century, the importance of tariffs diminished in the US. For one thing, with its productivity already surpassing that of the UK, the US became the world’s biggest economy. Also the world leader in industrial development, the US could better afford the impact of reduced trade protection. Out of consideration for a fair tax system, the country shifted to a new system with income taxes as the major source of fiscal revenue. In addition, some regard tariffs as undesirable because they can lead to corruption. Given the myriad of commercial products, there are bound to be loopholes for tariff exemptions. The higher the tariffs, the greater the incentive for seeking tax exemptions and the more money the briber is willing to pay. In light of Trump’s proposal to impose tariffs on imports from all countries, commentators are already concerned about the considerable administrative costs involved in handling tariff exemption applications and the potential rise in corruption cases.

Trump’s views on tariffs may be influenced by Robert Lighthizer, the trade representative he appointed during his last presidency. Perhaps that is why Lighthizer was one of the few cabinet members who managed to serve out his full four-year term without being fired by Trump. Last year, Lighthizer published a new book entitled No Trade Is Free, presenting his narrative on world trade and China trade. Adopting a rather hawkish stance, the book paints a generalized picture of tit-for-tat dynamics between China and the US. It depicts China as the country firing the first shot with its policies, resulting in a trade deficit for the US and causing job losses. The US responds by retaliating, leading to a trade war, etc.―a narrative that has become all too familiar today.

President authorized by Constitution to directly revise tariffs

Just like Trump, Lighthizer is also gravely concerned about the US trade deficit. He believes that America should maintain a balanced trade and, towards this end, the government can depreciate the greenback or force other currencies to appreciate by imposing tariffs on countries unwilling to comply. Such a tactic is reminiscent of the Plaza Accord in the 1980s, under which the US pressured the Japanese yen to appreciate. With Trump’s possible return to the White House, Lighthizer may regain favour and even assume a higher position than trade representative.

Judging by Trump’s personality and behaviour during his first tenure, if re-elected, he would most likely levy tariffs on imports from all nations, dealing a severe blow to global trade. According to the US Constitution, while the power to set tariffs rests with Congress rather than the president, under certain circumstances—such as trade discrimination by a foreign country against US products or unfair trade practices against the US, Congress can authorize the president to retaliate with tariffs.

The long-standing narrative of China’s unfair trade practices, framed by the US to suppress China, is one of the few consensuses between Republicans and Democrats. Trump may be able to bypass the Constitution and directly introduce an across-the-board 60% tariff on Chinese imports. However, his proposal to impose 10% or 20% tariffs on imports from all other countries may face challenges from the Democrats. This will depend on the post-election distribution of seats in the two houses of Congress.

全球矚目的美國總統大選競爭激烈,特朗普和賀錦麗在各民意調查中支持比率你追我趕,到本文執筆時,誰都沒有把對方拋離在統計誤差之外,而且在各種因素影響下,民意調查的準確性成疑。2016年的民意調查表示希拉莉會勝出,兩年前的民意調查又顯示國會中期選舉會出現共和黨大勝的紅色浪潮,但兩者均沒有發生。然而,無論誰當選,都會嚴重改變國際政經格局,特別是常被認為「離經叛道」的特朗普上台。

特朗普的對外經濟政策取向在首個總統任期內就相當明顯,口號是「使美國再次偉大」,具體乃否定合作共贏、退出多邊協議、打擊對美國有順差的貿易夥伴、以關稅為主要武器等。他這次捲土重來,已多番表示,若再當選便會向所有外國產品加徵關稅,中國產品的稅率會是60%至100%甚至更高,其他國家的也會高達10%甚至20%。
從開國到二戰實施保護主義

特朗普特別喜歡以關稅為國際談判的武器,威逼其他國家就範。他在2018年發動貿易戰,恣意以國家安全為藉口,向歐盟及中國等地產品徵收大幅關稅。當時他得意地說自己是「關稅人」(I am a tariff man),並認為「貿易戰很好,並容易取勝」(trade wars are good, and easy to win)。約兩周前在芝加哥競選講話中,特朗普說「關稅是最美麗的單詞」(the most beautiful word)。在另一個場合,他誇口說可以用關稅來爭取和平。若有兩國大動干戈,他可以致電雙方,說若不停戰,美國就向他們徵收關稅,那戰爭自然會終結。

特朗普對關稅愛不釋手,似乎是處理對外經濟事務的萬靈丹,背後或有多種原因和情意結。比較表面的,是從他作為商人的視角來看,貨品可以賣出就是好事,賣不出就是壞事,所以美國有貿易逆差就是個問題,而關稅可以打擊對方的銷售,自然是個好政策。其次,無論是有意或無意,特朗普錯誤地堅持關稅稅款由外國而非美國消費者承擔,同時這些稅款又可以用來減輕美國企業和個人的稅務,何樂而不為?

稍為更深層的,是關稅作為美國對外的重要經濟手段,有着長遠的歷史,而特朗普對關稅的看法和政策,似乎是相關歷史的迴響。美國在二戰後領導及規劃全球經濟秩序,祭出自由貿易的大旗,鼓吹其他經濟體開放市場,似乎自由貿易是美國的一貫國策和思維。但事實上,美國從開國到二戰期間,大部分時間都實施高度的貿易保護主義,而關稅正是其中主要的工具。

美國開國後,對政府在經濟發展的角色,一直存有反覆和爭論,但主要傾向是以政府有形之手推動經濟。

美國當時以農業為主,經濟實力不及英國,但以英國為主要競爭對手,不接受當時英國的自由貿易思想,反而以高關稅保護和促進工業,及以政府補貼來發展基建,試圖追上英國。這種情緒在1812年英美再度交戰後更為強烈。
有助維繫社會和諧促進經濟

美國對關稅的重視,從多年來稅率的高度可見一斑。若單以受關稅影響的進口商品來計算,平均稅率在十九世紀二十年代一度高至60%,該世紀後半部平均稅率也介乎40%至50%之間。即使包括零關稅的進口商品,在整個十九世紀,平均關稅也有30%。到二十世紀初,稅率一度下調,但在該世紀三十年代經濟大蕭條期間通過的《斯姆特-霍利關稅法案》(Smoot-Hawley Tariff Act),又將受關稅影響的進口商品平均稅率回升到約60%。高關稅引致貿易夥伴的報復,各國相繼以鄰為壑,被認為是大蕭條期間經濟陷入極度困境的一個原因。

美國的高關稅除了保護國內工業發展,也是政府的主要財政收入。雖然較高稅率不一定帶來較多稅款,但關稅畢竟佔了美國十九世紀多個財政年度政府收入的90%或以上。

1870至1910年的數十年內,這個比率平均也有50%。關稅佔財政收入的比例這麼高,主要原因是當時沒有所得稅。雖然在美國內戰時已出現個人所得稅,但今天理解的美國企業和個人所得稅,分別只在1909年和1913年才立法設定,隨後關稅在財政的重要性便愈來愈低了。然而,在1913年之前的百多年間,關稅收入賦予美國政府相當多的財政空間,去維繫社會和諧及促進經濟發展。雖然關稅和保護主義在美國歷史上對工業和經濟發展有多少促進作用仍有相當爭議,但關稅的長期和顯著存在使美國人更容易接受它。

然而,作為一個稅種,關稅有一個明顯問題,就是它本質是累退而非累進的,和今天常見的所得稅相反。無論富人窮人,購買同一外國產品,需付的關稅稅款相同,但稅款作為富人收入的比率,低於作為窮人收入的比率,即收入較高稅率反而較低,違反了很多人認為公平稅制該有的原則。

這些考量,雖然不是美國內戰的主因,卻也反映一些情況。當時美國南方收入比北方低,但進口要付同樣多的關稅,然而關稅所保護的工業卻主要在北方。

美國在二十世紀初降低關稅的重要性,一來是當時生產已超過英國,成為全球最大經濟體,工業也達到領先地位,可以承擔減少貿易保護的影響,同時亦考慮到稅制的公平性,因此改為以所得稅為主要財政來源的新制度。此外也有人認為關稅導致貪污腐敗而不可取。世上商品種類繁多,總有些符合豁免關稅的條件。關稅愈高,申請豁免的誘因愈大,行賄者願意付出的賄款也愈多。已有論者擔心,美國若按特朗普的建議對全球徵收關稅,將要付出多少處理申請豁免的行政費用,及貪污行賄案例會上升多少。

特朗普對關稅的看法,或受到他當總統時任命為美國貿易代表的羅伯特.萊特希澤(Robert Lighthizer)所影響。又或因他兩位所見略同,後者是少數能完成四年任期而沒有被特朗普辭退的內閣成員。萊特希澤於去年出版了名為No Trade Is Free的新書,論述他對世界和中國貿易的看法,態度相當鷹派,大致是中國在貿易上「先不仁」,以各種政策造成美國貿易逆差,工人失去崗位,美國才「後不義」,掀起貿易戰等到今天已經是耳熟能詳的論述。
憲法授權總統直接改動關稅

和特朗普一樣,萊特希澤很在意美國的貿易逆差,認為美國應回到貿易平衡,而要達到這目的,可以通過美元貶值或迫使其他貨幣升值,若不升值便對有關國家產品徵收關稅,聽起來正是上世紀八十年代《廣場協議》中,美國逼日圓升值的手法。特朗普若重回白宮,萊特希澤或會再受重用,甚至擔任比貿易代表更高的職位。

以特朗普的性格和他首任總統時的行為來看,若再度當選,極有可能對全球大徵關稅,給全球貿易帶來嚴重的衝擊。按照美國憲法,制定關稅的最終權力在國會而非總統手上,但國會授權總統在某些情況下可直接改動關稅,如外國對美國產品有貿易歧視或對美國不公平貿易等,美國總統可以用關稅回擊。

美國長期營造中國不公平貿易的說法,加以打壓中國是共和、民主兩黨的少數共識之一,特朗普或可不受憲法約束,直接對中國產品一律徵收60%關稅。但對其他國家統一徵收10%或20%關稅,則可能受到民主黨的挑戰,那時便要看這次選舉後國會兩院議席的分配了。
