You can find it \u003Ca href=\u0022https:\/\/www2.isye.gatech.edu\/faculty\/Alan_Erera\/logistics\/2018\/01\/18\/global-trade-101.html\u0022\u003Ehere\u003C\/a\u003E. The post makes a number of basic points using a simple example. I\u2019ll also repeat here that, these years later, I\u2019m still not an economist and I\u2019m not otherwise an expert on certain aspects of international trade. However, I am someone who thinks quite a bit about supply chains and thus, given the configuration of the modern global economy, I do think about international trade and transportation and the potential impact of various import tariffs on supply chains.\u003C\/p\u003E\u003Cp\u003EFirst, here is an update on the scale of international trade and its role within the US economy. I\u2019ll use official trade statistics provided by the US Census Bureau. If we look at the \u003Cem\u003Etrade of physical goods\u003C\/em\u003E which is the first thing that most people think about when it comes to trade, the US imported \u003Cstrong\u003EUS$3.112 trillion\u003C\/strong\u003E worth of goods in FY2023. That is simply a lot of stuff. Note that imported goods can be finished products that are distributed (eventually) through various retail channels to end consumers. But they can also be various \u003Cem\u003Einputs to production\u003C\/em\u003E: supplies, components, or work-in-progress inventory that feeds US manufacturing enterprises. A very good example along these lines is Canadian heavy crude oil, shipped to US petroleum refineries as the key input to the production of refined petrochemicals like gasoline, jet fuel, and other products. You can \u003Ca href=\u0022https:\/\/www.theglobeandmail.com\/business\/article-trumps-tariff-pledge-weighing-heavily-on-us-refiners-that-rely-on\/\u0022\u003Eread elsewhere\u003C\/a\u003E why the US currently imports heavy crude from Canada when it (already) produces more crude oil than it consumes each year and is thus (already) a net exporter.\u003C\/p\u003E\u003Cp\u003EMost US consumers understand that large parts of our economy rely on imported goods. Fewer might think about the sheer scale of the US \u003Cem\u003Egoods export economy\u003C\/em\u003E. Looking again at FY2023, the US \u003Cstrong\u003Eexported US$2.051 trillion\u003C\/strong\u003E worth of goods (includng some of that aforementioned US-drilled crude oil). Wow, again, that is a lot of stuff. But it is true that the balance of trade here currently favors imports over exports. Since we import more goods value than we export, we ran a \u003Cstrong\u003Egoods trade deficit\u003C\/strong\u003E with the rest of the world of \u003Cstrong\u003EUS$1.061 trillion in FY2023\u003C\/strong\u003E.\u003C\/p\u003E\u003Cp\u003EA large part of the US economy today is the provision of \u003Cem\u003Eservices\u003C\/em\u003E and not goods. There are all sorts of services: food service, financial services, educational services, transportation services, consulting services, and so on. And the US does trade in services as well, both importing services from foreign providers while \u003Cstrong\u003Eexporting services to foreign customers\u003C\/strong\u003E. In fact, the US ran a \u003Cem\u003Etrade surplus\u003C\/em\u003E in services of \u003Cstrong\u003EUS$288 billion\u003C\/strong\u003E which reduced the overall \u003Cstrong\u003Enet trade deficit to US$773 billion in FY2023\u003C\/strong\u003E.\u003C\/p\u003E\u003Cp\u003ENow let\u2019s discuss tariffs for a bit, and let\u2019s consider duties on imported goods. If the US places a 10% tariff on a bundle of goods (perhaps a specific category of goods from a specific set of countries), then \u003Cstrong\u003Eimporters of those goods\u003C\/strong\u003E must pay a \u003Cem\u003Ecustoms duty\u003C\/em\u003E on the declared goods before they can be moved into the US (so-called customs-clearing). As many have noted already, these importers-of-record are firms doing business in the US (or individuals) that have arranged for the importation. Examples of such importers include retailers like Walmart and producers like Ford and ExxonMobil. Customs duties collected go into the US Treasury, similar to personal income taxes, social security and Medicare taxes, and corporate income taxes. However, the fraction of US government revenue raised by tariffs has been very small for a long period of time. In FY2023, the total collected customs duties by the US Treasury was about US$80 billion. In fact, FY2023 trade was down a bit from FY2022 when total goods imports were US$3.35 trillion and total collected duties were US$112 billion, or an average duty of about 3.3%.\u003C\/p\u003E\u003Cp\u003ESo, how much revenue could be raised by new tariffs? Let\u2019s imagine a strange world where new US import duties did not distort the economy in any way: the same value of goods is assumed to be imported even though both \u003Cem\u003Edemand\u003C\/em\u003E for those goods would likely adjust and the \u003Cem\u003Epurchasing power\u003C\/em\u003E of each US$ might increase. If the average duty were increased to 10%, the total revenue produced to the US Treasury in FY2023 would have been US$311 billion. How about a 25% average tariff? Well, of course, US$778 billion. For comparison, the US Treasury received US$2.43 trillion in personal and US$530 billion in corporate income taxes in FY2023, an amount \u003Cstrong\u003Enearly equivalent to a universal 100% tariff on the imported goods value basis for all imported goods\u003C\/strong\u003E. The tiny yellow sliver in the figure below shows how little total customs duty revenue has been collected over time and how little changed it has been compared to other revenue sources.\u003C\/p\u003E\u003Cp\u003ELike any other tax, a tariff can be useful to governments as they seek to design mechanisms to fund (important) government activities while distorting economic activity to favor or disfavor various groups of people, businesses, investors, industries, nations, regions etc. It\u2019s also safe to say that, like any other tax, it can be difficult to determine how economic activity will be specifically distorted by any specific tariffs. In fact, it may be more difficult with tariffs for a few reasons. The first is that unlike a sales tax, a tariff on imported goods occurs upstream of the point-of-sale. Instead, \u003Cstrong\u003Etariffs create increases in supply chain costs for importers\u003C\/strong\u003E, and the impact of tariffs on consumers depends on what happens as a result of these cost increases.\u003C\/p\u003E\u003Cp\u003EFirst, it should be noted that some supply chain cost increases cannot be borne at all and can lead to the elimination of some products in the marketplace. Why? A cost increase can lead a producer to decide that a product cannot be profitably produced and marketed, and this is true even if a replacement supply source with a lower (tariff-inclusive) cost of supply can be identified. A retailer may make a similar decision for an imported product. If producers or retailers continue to keep a product in the market, they could decide to lower its quality in some way or to pass on portions of the cost increase directly to its customers. But the supply chain cost persists; perhaps a different supplier could be identified not subject to the tariff, but if that supplier were already providing the same input at the same quality for a lower price they would be used already. Since profitability is likely to be impacted, owners and investors as well as employees of the importer will also likely to be impacted. These interactions are all naturally somewhat complex and the outcome is difficult to predict.\u003C\/p\u003E\u003Cp\u003EI\u2019ll finish with a thought. If a government wishes to use new tariffs to yield a political outcome beyond simply raising revenue, they will likely need to be designed to produce a significant (and noticeable) distortion to some portion of the economy. If the distortion is mild, no change of behavior seems likely to occur. It seems as if the US is about to attempt some new experimentation with tariffs to both influence the behavior of trade partner nations and to create a significant government revenue source. We will likely get to see firsthand what kind of economic distortion they induce.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EProfessor Alan Erera provides insight into the impact of tariffs on global trade and supply chains by expanding on his earlier article and emphasizing the current challenges faced by businesses adapting to new trade policies.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Professor Alan Erera provides insight into the impact of tariffs on global trade and supply chains."}],"uid":"27233","created_gmt":"2025-02-19 15:19:06","changed_gmt":"2025-04-28 20:25:54","author":"Andy Haleblian","boilerplate_text":"","field_publication":"","field_article_url":"","location":"Atlanta, GA","dateline":{"date":"2025-02-19T00:00:00-05:00","iso_date":"2025-02-19T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"676344":{"id":"676344","type":"image","title":"How Tariffs May Reshape Global Trade and Supply Chains","body":null,"created":"1739987425","gmt_created":"2025-02-19 17:50:25","changed":"1740057559","gmt_changed":"2025-02-20 13:19:19","alt":"Illustration of container ship in ocean with global map overlayed and port cranes in the background","file":{"fid":"260116","name":"HowTariffsTradeReshapingGlobalTradeandSC.jpg","image_path":"\/sites\/default\/files\/2025\/02\/19\/HowTariffsTradeReshapingGlobalTradeandSC.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/02\/19\/HowTariffsTradeReshapingGlobalTradeandSC.jpg","mime":"image\/jpeg","size":134087,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/02\/19\/HowTariffsTradeReshapingGlobalTradeandSC.jpg?itok=4Lsmuv91"}},"676337":{"id":"676337","type":"image","title":"Figure - Federal Revenue Trends Over Time 2015-2024","body":"\u003Cp\u003EFederal Revenue Trends Over Time 2015-2024\u003C\/p\u003E","created":"1739981085","gmt_created":"2025-02-19 16:04:45","changed":"1739987939","gmt_changed":"2025-02-19 17:58:59","alt":"Federal Revenue Trends Over Time 2015-2024","file":{"fid":"260108","name":"Figure-FederalRevenueTrendsOverTime_2015-2024.jpg","image_path":"\/sites\/default\/files\/2025\/02\/19\/Figure-FederalRevenueTrendsOverTime_2015-2024.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/02\/19\/Figure-FederalRevenueTrendsOverTime_2015-2024.jpg","mime":"image\/jpeg","size":94576,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/02\/19\/Figure-FederalRevenueTrendsOverTime_2015-2024.jpg?itok=hlnri2Bm"}},"676336":{"id":"676336","type":"image","title":"Alan Erera, Manhattan Associates\/Dabbiere Chair and Professor and Associate Chair for Research","body":null,"created":"1739980983","gmt_created":"2025-02-19 16:03:03","changed":"1739981054","gmt_changed":"2025-02-19 16:04:14","alt":"Alan Erera, Manhattan Associates\/Dabbiere Chair and Professor and Associate Chair for Research","file":{"fid":"260105","name":"aerera-square_500px.jpg","image_path":"\/sites\/default\/files\/2025\/02\/19\/aerera-square_500px.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/02\/19\/aerera-square_500px.jpg","mime":"image\/jpeg","size":21730,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/02\/19\/aerera-square_500px.jpg?itok=fKu0ILof"}}},"media_ids":["676344","676337","676336"],"related_links":[{"url":"https:\/\/www.isye.gatech.edu\/users\/alan-erera","title":"About Dr. Alan Erera"}],"groups":[{"id":"1243","name":"The Supply Chain and Logistics Institute (SCL)"}],"categories":[{"id":"131","name":"Economic Development and Policy"},{"id":"145","name":"Engineering"}],"keywords":[{"id":"167003","name":"tariffs"},{"id":"187175","name":"foreign trade"},{"id":"167074","name":"Supply Chain"},{"id":"233","name":"Logistics"},{"id":"186857","name":"go-gtmi"},{"id":"194489","name":"scl-spot"}],"core_research_areas":[{"id":"39461","name":"Manufacturing, Trade, and Logistics"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:info@scl.gatech.edu\u0022\u003Einfo@scl.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
