How can economics help you understand international trade?

How can economics help you understand international trade? International trade is the exchange of goods and services across borders. It affects the prices, production, consumption, and welfare of people and countries. Economics is the study of how people make choices under scarcity and how they interact with each other in markets. Economics can help you understand the causes and consequences of international trade, as well as the policies and institutions that regulate it. In this article, you will learn about some of the key concepts and tools that economists use to analyze international trade.

1 Comparative advantage

One of the most fundamental ideas in economics is comparative advantage. It means that a country can produce a good or service at a lower opportunity cost than another country. Opportunity cost is the value of the next best alternative that is forgone as a result of making a choice. For example, if a country can produce more wheat than another country with the same amount of resources, it has a comparative advantage in wheat production. By specializing in the goods or services that they have a comparative advantage in, countries can increase their total output and trade with each other to gain from mutual benefits.

Os países se especializam na produção de bens e serviços onde tem vantagem comparativa e trocam os produtos entre si. Vantagem comparativa consiste em produzir a um custo de oportunidade menor que outro. É o caso da agricultura brasileira, com recursos abundantes como sol e grandes extensões de terra , produz uma enorme quantidade de grãos , alimentando metade do planeta e fornecendo alimentos a preços competitivos para dezenas de país. O Brasil é hoje celeiro do mundo!

International trade is governed by what economists call "Market Forces". These are essentially consumer sentiments, which is a direct indicator of the favor to a product. To quote an example, say, a country X wants oil. Three other countries A, B and C are ready to sell oil to X. Country A has a highly developed Technology, but B and C still hire humans to mine oil. Granted, A will have slightly more expensive oil, but the technological gain will be too much to ignore. So, X buys oil from A. This is, in essence, what international trade is. A country will look only for its own gain in the process, and when it discovers another country that benefits, they become trade partners, through documents called Trade Agreements.

Economics elucidates international trade by analyzing comparative advantage, where nations specialize in industries based on efficiency. Key economic indicators, like balance of payments, unveil a nation's trade dynamics, reflecting the impact of exports and imports. Exchange rate analysis assesses currency values, influencing trade competitiveness. Economic models guide policy decisions, such as tariffs and subsidies, shaping trade environments. Development economics contextualizes trade within broader socio-economic goals, ensuring inclusive growth. Overall, economics provides a holistic framework for comprehending the intricacies of Intl trade, guiding policymakers in fostering sustainable and beneficial global economic interactions.

2 Trade barriers

However, international trade is not always free and fair. There are often trade barriers that restrict the flow of goods and services across borders. Trade barriers can be tariff or non-tariff. A tariff is a tax imposed on imported goods or services, which raises their price and reduces their quantity. A non-tariff barrier is any other policy or regulation that makes it harder or more costly for foreign producers to sell their goods or services in a domestic market, such as quotas, subsidies, standards, or licenses. Trade barriers can be motivated by various reasons, such as protecting domestic industries, generating revenue, or achieving political or social goals.

Barreiras comerciais restringem o fluxo de bens . Podem ser tarifárias e Barreiras não tarifárias . A tarifa ad valorem è o imposto que o importador paga na alfândega quando da entrada da mercadoria estrangeira. A Barreira não tarifaria pode ser de diversos tipos como, cota, licença subsídio, normas impossíveis de serem cumpridas. Normalmente, em períodos de recessão econômica ou pouco crescimento, países fazem uso desses mecanismos para proteger a entrada de produtos importados, proteger a indústria nacional, gerar receitas com tarifas elevadas ou atingir objetivos sociais.

3 Trade agreements

To reduce or eliminate trade barriers and promote international trade, countries often negotiate and sign trade agreements. Trade agreements are contracts between two or more countries that specify the rules and terms of trade between them. Trade agreements can be bilateral, meaning between two countries, or multilateral, meaning between many countries. Trade agreements can cover different aspects of trade, such as tariffs, quotas, subsidies, services, intellectual property, labor, or environment. Trade agreements can have positive or negative effects on the trade partners, depending on their relative bargaining power, preferences, and outcomes.

Enquanto as vantagens comparativas promovem trocas entre os países, barreiras comerciais restringem o comércio internacional. Acordos comerciais servem para reduzir ou eliminar barreiras comerciais quer seja barreiras tarifárias ou barreiras não tarifárias. De um modo geral, os acordes comerciais ampliam o fluxo comercial , em média em 60% entre os países. Acordos comerciais também podem causar aspectos negativos para determinados setores da economia . A diplomacia brasileira , ao negociar acordos comerciais , negocia cada item tarifário. Mercosul e União Europeia estão perto da negociação de um acordo comercial entre os dois blocos que apresentam uma pauta exportadora complementar, com vantagens para ampliação de mercado para ambos.

4 Trade models

To evaluate the effects of international trade and trade policies, economists use trade models. Trade models are simplified representations of reality that capture the essential features and relationships of trade phenomena. Trade models can be based on different assumptions and frameworks, such as perfect or imperfect competition, constant or increasing returns to scale, homogeneous or differentiated products, or one or multiple factors of production. Trade models can help explain how trade affects the prices, quantities, revenues, costs, profits, wages, incomes, and welfare of the trading countries and their agents.

5 Trade indicators

To measure and compare the performance and position of countries in international trade, economists use trade indicators. Trade indicators are statistics or ratios that summarize or reflect some aspects of trade activity or performance. Trade indicators can be based on different sources and methods of data collection and calculation, such as customs, surveys, or national accounts. Trade indicators can include the value, volume, or share of exports, imports, or trade balance, the composition, direction, or diversification of trade, the terms of trade, the trade openness, or the trade competitiveness of a country.

6 Trade issues

International trade is not only an economic phenomenon, but also a social, political, and environmental one. It involves and affects many stakeholders, interests, and values. Therefore, international trade raises many issues and challenges that require careful analysis and discussion. Some of the common trade issues are the distribution of gains and losses from trade, the impact of trade on development, poverty, inequality, human rights, labor standards, or environmental sustainability, the role of trade in regional or global integration or conflict, the governance and legitimacy of trade institutions or agreements, or the future of trade in a changing world.

Economics indeed provides a valuable framework for analyzing the factors that influence international trade and its impact on economies. From resource endowments and production costs to technology government policies, and consumer preferences, all these factors play a crucial role in determining the volume and direction of international trade. Comparative advantage, the effect of trade on factor prices, and the relationship between trade and globalization are key concepts that help us comprehend and evaluate the significance of international trade. By applying economic principles, we can better understand the complexities and implications of global trade for economic growth, employment, income distribution, and overall economic development.
