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...

This study, set against the backdrop of escalating trade tensions between China and the United States, examines the impact of soybean tariff adjustments on the abnormal asymmetric behavior in the futures market. By employing specialized analytical methods that capture market volatility asymmetry...

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...

When the UK left the EU, it introduced a new import tariff schedule, one of the largest MFN tariff reforms in decades of a developed economy. This paper exploits this policy change to estimate the elasticity of imports to MFN tariffs, addressing the endogeneity of trade policy through two...

Using administrative longitudinal firm- and plant-level data from Mexico that links manufacturing firms to their customs records and covers the period 2014 - 2023, I examine whether US tariffs targeting China have contributed to a manufacturing revival in the southern part of North America....

We consider welfare impacts of prohibitive tariffs on trading partners. Initially, there is prohibitive tariff by one country and a zero tariff by its trading partner. Thereafter, the trading partner also resorts to prohibitive tariff. We demonstrate how prohibitive tariffs by the trading...

Time-of-use (ToU) tariffs are an efficient mechanism for managing peak electricity demand, but consumer adoption remains low and usage suboptimal. This paper examines three possible economic and behavioral barriers: (1) The monetary compensation available under ToU tariffs may be insufficient...

This paper draws on trade data, academic literature, government reports, and policy documents to contextualize historic trade dynamics and trace the buildup to recent disputes. Using a comparative framework, we analyze how Sino-U.S. and Sino-Canada relations have shaped and continue to shape...

• The 2025 US tariffs are an own goal: American importers and consumers bear nearly the entire cost. Foreign exporters absorb only about 4% of the tariff burden - the remaining 96% is passed through to US buyers. • Using shipment-level data covering over 25 million transactions valued at...

We study how firms' expectations respond to prospective tariff shocks using a randomized survey experiment among Swiss manufacturing firms. When confronted with potential U.S. tariffs, respondents expect sizable declines in turnover and investment, yet anticipate increases in ex-tariff export...

• The EU-India FTA generates mutual economic gains of 0.12-0.13% of GDP for both partners, with bilateral trade surging by 41-65%. • Since the 50 percentage points tariffs imposed by the US cost India 1.6% of GDP, the EU-India FTA provides a crucial hedge while the EU demonstrates commitment...

The return of trade policy as an instrument of geopolitics has raised concerns about the future of the global trading system. But Trump's tariffs of 2025 have not led to a collapse of global trade. The key reason for this resilience is that Trump's tariffs are discriminatory, i.e. the US has a...

We study how firms' expectations respond to prospective tariff shocks using a randomized survey experiment among Swiss manufacturing firms. When confronted with potential U.S. tariffs, respondents expect sizable declines in turnover and investment, yet anticipate increases in ex-tariff export...

The intersection of environmental policies and trade policies on external diseconomies has received considerable attention in recent years. However, the impacts of the timing of pollution taxes versus import tariffs on economic performance have not been formally considered, and this forms the...

This paper dissects the impact of United States (US) tariffs introduced in 2025 on firm exports, concentrating on heterogeneity. Using comprehensive export customs data to the US from six selected Asian countries from January 2024 to August 2025, we confirm that for the first few months after...

Since 2018, tariffs have re-emerged as a tool for protecting domestic economies, particularly in the US. This paper examines the macroeconomic and welfare effects of various import tariff scenarios using a four-region dynamic general equilibrium model with a multi-sectoral production network....

This paper examines the impact on crude oil prices of the trade tariffs announced by the Trump administration on 2 April 2025 ("Liberation Day"). More specifically, it uses fractional integration methods to analyse daily data on WTI, Brent and Murban oil prices spanning the period from 3 June...

This paper presents a dataset and an analytical framework to study the welfare effects of tariff changes on women. The data is an extension of the Household Impacts of Tariffs (HIT) dataset, which contains harmonized household survey data for 54 low and lower middle-income countries. It includes...

This paper develops a dynamic real-options model of tariff deterrence in which the exporting country, though subject to the importing country's market power, assumes the role of leader in a Stackelberg framework under uncertainty by acting preventively to dissuade the importer from imposing a...

This paper introduces a framework that integrates Quadratic Almost Ideal Demand System (QUAIDS) elasticities with the ADB Multi-Region Input-Output (MRIO) database to evaluate the direct and indirect impacts of tariffs on Value Added at the country-sector level. Using the data on USA tariffs...

The digitalization of global supply chains and the increasing complexity of international trade have created both opportunities and challenges for customs administrations. The European Union has responded to these dynamics through the new EU customs reform, which aims to achieve full digital...

On 1 March 2018, President Trump declared a 25% tariff on certain steel imports by invoking Section 232 of the 1962 Trade Expansion Act. The tariff pitted two of America's most storied and interconnected industries, steel and auto producers, against one another and made allies out of longtime...

The trade war with China has cost US producers and consumers hundreds of billions of dollars since 2018. Yet relatively few US businesses took action to oppose it. This study reports the results of an elite survey experiment on business political activity toward trade policy. Researchers...

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 paper introduces a new measure of tariff evasion through rerouting and applies it to the 2018 U.S.–China trade war, focusing on Vietnam as a transit country. We use transaction-level trade data and define rerouting as the flow of a granular eight-digit HS product from China, through...

World Tariff Profiles 2025 provides comprehensive information on the tariffs and non-tariff measures imposed by over 170 countries and customs territories. The publication starts with a breakdown of the tariffs imposed by these economies. Tariff data are presented in comparative tables and in...

This paper explores the application of Natural Language Processing (NLP) techniques to automate Harmonized System (HS) tariff line transposition, employing a three-stage process: unique 1:1 tariff code matching (Round 1), exact description matching (Round 2), and "smart" description matching...
