How do import tariffs affect employment? We develop an empirical strategy to identify the effects of tariffs using difference-in-differences, comparing anti-dumping (AD) investigations resulting in dumping tariffs to those not resulting in dumping tariffs. We find that an AD tariff decreases...

Transaction-level quantity discounts are a pervasive feature of US trade, shaping both price variation and tariff incidence. Using administrative microdata, we show that these discounts reflect transaction-level scale economies rather than market power. Accounting for these micro-level economies...

In April 2025, the United States abruptly announced exceptionally high tariffs on imports from more than 180 countries (levels not seen in nearly 150 years) shocking the global economy. Within a week, most measures were postponed for 90 days (until July 9, 2025), but tariffs on Chinese goods...

This brief presents impact assessments of increased tariffs based on simulations using the Global Integrated Monetary and Fiscal (GIMF) macroeconomic model. The current increases in US import tariffs are shown to reduce aggregate output across all major economic regions. The most pronounced...

The United States (US) and European Union (EU) are at risk of entering a full-blown trade war. Three months ago, on "Liberation Day", US President Donald Trump imposed high import tariffs on almost all countries, including the EU. He then suspended them at short notice to negotiate with over 90...

Addressing climate change requires green technology deployment. This paper uses firm-level import data in 35 emerging markets to examine how trade policies affect firms’ imports of products associated with solar, wind power, and electric vehicle value chains. Panel estimates show a...

This study applies the Quadratic Almost Ideal Demand System (QUAIDS) to the Asian Development Bank's Multi-Region Input-Output (MRIO) dataset to estimate global demand and supply elasticities across intermediate vs. final, and domestic vs. foreign sectors. Using pooled data from 2021-2023,...

Using disaggregated US household expenditure data, we study the distributional consequences of the US-China trade war. We estimate a highly flexible demand system to compute household-specific price indexes. The increases in US tariffs on Chinese products between 2018 and 2019 led to an average...

We study how strategic inputs-petitions, evidence, and lobbying claims-shape the making and incidence of trade policy. South Africa's International Trade Administration Commission provides a rare, docketed forum where any stakeholder can seek product-specific tariff changes and must justify them...

The turbulent first eleven months of Donald Trump's second presidency has been characterized by policy actions and statements that create large uncertainties and sideline multilateral cooperation. The Trump administration has fueled substantial trade policy uncertainty globally, as well as...

We develop a modified version of the Flam and Helpman (1987) framework of North–South trade in vertically differentiated products, by endogenizing the labour market participation decisions of heterogeneous households and allowing for tariffs to substitute for income taxes. The model reveals a...

How do import tariffs affect employment? We develop an empirical strategy to identify the effects of tariffs using difference-in-differences, comparing anti-dumping (AD) investigations resulting in dumping tariffs to those not resulting in dumping tariffs. We find that an AD tariff decreases...

Motivated by current events, this paper assesses the impact of tariff increases on bilateral greenfield foreign direct investment (FDI) over the period 2016-2023. Leveraging a comprehensive dataset of announced greenfield investment projects, official FDI statistics, and bilateral product-level...

We examine the potential economic impacts of the new United States (US) tariff on Cambodia using a dynamic global general equilibrium model (GTAP-FIN). We simulate the impact of US tariff increases announced in August 2025 while also examining two additional hypothetical cases for Cambodia....

The recent changes in trade policy have significantly impacted trade flows. There is an ongoing debate on whether and to what extent firms may have also reacted to the new trade barriers by modifying the spatial organization of their multinational production to circumvent them. This paper aims...

Following the upcoming U.S. elections, the EU should prioritize defending the multilateral trade system, as a collapse in global economic cooperation could impact Europe up to four times more than direct U.S. tariffs alone. Potential U.S. trade policies under either a Harris or second Trump...

This study aims to examine the relationship between customs policy and the economic blocs of which Egypt is a member, with a focus on the theory of New Regionalism and modern trends in customs policies. Egypt joined numerous economic blocs following its accession to the world trade organization...

This paper first presents a dynamic model that features both real and monetary aspects of international trade and is capable of dealing with both full employment and secular unemployment. The model is then utilized to examine the effect of a tariff on the terms of trade, the trade pattern, real...

Rising globalization has exerted a downward pressure on global tariffs, thereby eroding tariff revenues in developing nations. We analyse how gains from lowering import tariffs are distributed within the firm and the corresponding tax (base) implications. First, we study the effect of tariff...

The trade war between the United States and China since 2008 has opened strategic opportunities to increase the economic market in ASEAN countries. This research aims to answer whether the trade war led to an oligopoly or a systemic market structure as a strategy for increasing demands,...

Against a backdrop of sharply rising inequality, the Tokyo Round of the GATT resulted in a 1.6 percentage point reduction in average US tariffs – larger than CUS-FTA, NAFTA, and the liberalization accompanying the granting of PNTR to China. We construct a novel IV based on the so-called...

This paper reveals significant errors in a key variable in international trade: tariff rates. The issues arise from incomplete reporting, leading to measurement error from false interpolation by the data provider, the World Integrated Trade Solution (WITS), and selection bias from dropping...
