Summary of Fundamentals of International Trade

## Introduction Digital trade reshapes how services, goods-related services, and technology interact across borders. This study material explains the main modes of supplying services internationally, the role of digitally delivered services, sectoral trends (banking, software, tourism, education), and policy challenges such as investment screening and digital taxation. Practical examples and comparisons help link theory to real-world practice. > **Definition:** Digital trade refers to cross-border commercial transactions in goods and services that are enabled or delivered through digital technologies and computer networks. ## 1. Modes of Supplying Services Internationally International services trade is commonly grouped into four modes. Breaking them down helps identify which sectors and policies apply. ### Mode 1 — Cross-border supply - Services supplied from the territory of one economy to the territory of another via communications or transport networks. - Typical examples: online consulting, software downloads, cloud data processing. > **Definition:** Mode 1 exports occur when the service supplier and consumer remain in their respective home countries while the service crosses the border. Practical examples: - A software firm in India sells SaaS access to a US company. - An online education platform in the UK offers a course to learners in Brazil. ### Mode 2 — Consumption abroad - The consumer crosses the border to receive a service. - Typical examples: tourism, international students, medical travel. > **Definition:** Mode 2 covers transactions where the consumer travels to the supplier’s country to obtain the service. Practical examples: - A patient from Czechia travels to Germany for specialized surgery. - A student from China studies at a university in Canada. ### Mode 3 — Commercial presence - A company establishes a legal presence abroad (subsidiary, branch, affiliate) to supply services locally. - Involves foreign direct investment (FDI) and often regulates market entry. > **Definition:** Mode 3 is trade through a foreign commercial presence, such as a bank opening a subsidiary. Practical examples: - A multinational bank establishes branches in several countries. - A software development firm opens a foreign subsidiary to service local clients. ### Mode 4 — Presence of natural persons - Individual service suppliers temporarily cross borders to supply services. - Gaining importance with specialized professionals and project-based work. > **Definition:** Mode 4 covers temporary movement of natural persons (consultants, engineers, doctors) who provide services abroad. Practical examples: - A foreign engineer works on an infrastructure project for six months. - A consultant travels to advise a foreign government. ## 2. Sectoral Overview: Key Services and Digital Components Services connected to goods and digitally delivered services form a large and growing part of world trade. - Services account for roughly half of global employment and a rising share of trade: from 17% in 1979 to 21.4% in 2021 and projections toward 25% by 2030. - In 2021, services represented about 6.3% of world GDP in traded value. Major traded services (by category and examples): - **Business, professional and technical services** — consulting, legal, engineering (≈40% of digitally delivered services) - **Computer and information services** — software, cloud, data processing (≈20%) - **Financial services** — banking, insurance, fintech (≈16%) - **Intellectual property** — licensing, royalties (≈12%) - **Insurance, telecommunications, audio-visual** — smaller but growing shares Did you know that digitally delivered services exports increased almost four times in value since 2005? Leading exporters and importers of services (high level): - Top exporters: US, UK, China, Germany, Ireland, France - Top importers: US, China, Germany, Ireland, UK, France - Regional notes: Europe supplies more than half of digitally delivered services; A
