Understanding the role of international trade and payments in the global economy

International trade and payments are an integral part of the global economy, allowing countries to exchange goods and services with one another and facilitating the flow of money across borders. In this article, we will explore the various aspects of international trade and payments, including the role of exchange rates and international financial institutions, and provide some examples and stories to illustrate the importance of this phenomenon.

One key aspect of international trade is the exchange of goods and services between countries. This can take many forms, such as exporting raw materials, intermediate goods, or finished products, or importing the same types of goods. For example, a country may export oil to another country in exchange for manufactured goods. In this way, international trade allows countries to specialize in the production of certain goods and services and to access a wider variety of goods and services than they could produce on their own.

The first known example of international trade occurred around 2500 BC, when the ancient Sumerians in Mesopotamia traded with the Indus Valley Civilization in modern-day India and Pakistan (World Trade Organization, 2019).

To illustrate the significance of international trade, consider the following case:

Imagine you own a small bakery in a rural town in the United States. You specialize in baking fresh bread and pastries using locally grown grains and other ingredients. However, you are limited by the small size of your local market and the availability of ingredients. One day, you receive an order from a bakery in France for a large quantity of your bread. They are willing to pay a premium price for the bread and cover the shipping costs.

?This unexpected order presents an opportunity for your business to expand and grow. By exporting your bread to France, you are able to access a new market and increase your sales. At the same time, the bakery in France is able to access a high-quality product that they may not be able to produce locally. This is just one example of how international trade can benefit both buyers and sellers, as well as the global economy as a whole.

Another important aspect of international trade is the payment for these goods and services. This can be done through the exchange of currencies, with each country using its own currency to buy and sell goods and services. The value of one currency in relation to another is determined by the exchange rate, which can be influenced by a variety of factors, including economic policies, interest rates, and market forces. For example, if a country has a strong economy and a stable currency, its exchange rate may be higher relative to another country with a weaker economy and currency.

The concept of free trade, in which countries remove barriers to trade and allow the free flow of goods and services across borders, has a long history. The philosopher Adam Smith argued in favor of free trade in his 1776 book "The Wealth of Nations," which is considered a foundational text in modern economics (Encyclopedia Britannica, 2021).        

International financial institutions, such as the International Monetary Fund (IMF) and the World Bank, play a crucial role in facilitating international trade and payments. The IMF, for example, provides financial assistance to countries experiencing economic difficulties, such as balance of payments crises, to help them stabilize their economies and return to sustainable growth. The World Bank, on the other hand, focuses on providing financial assistance and advice to developing countries to help them reduce poverty and promote economic development.

In the context of international trade, public policy plays a significant role in shaping the rules and conditions under which trade takes place. For example, governments may use tariffs, quotas, and other trade barriers to protect domestic industries from foreign competition or to achieve other policy objectives, such as environmental protection or public health. In the context of international trade, microeconomics can help to understand how trade affects the production, pricing, and distribution of goods and services, as well as the welfare of firms and households.

For example, consider a country that imposes a tariff on imported goods. This policy may be motivated by a desire to protect domestic industries from foreign competition. However, from a microeconomic perspective, the tariff may also have unintended consequences, such as raising the price of imported goods for domestic consumers, reducing the competitiveness of domestic firms that use imported inputs, and potentially leading to a reduction in overall economic efficiency. Let's say that a country imposes a 10% tariff on imported TVs. This policy may be motivated by a desire to protect the domestic TV manufacturing industry from foreign competition.

From an economic perspective, the tariff will have the following effects:

1.????The price of imported TVs in the domestic market will increase by 10%. For example, if an imported TV normally costs $500, the tariff will add an additional $50, making the final price $550.

2.????The domestic TV manufacturing industry may benefit from the tariff, as it will make imported TVs more expensive and therefore less competitive with domestic TVs. This may lead to an increase in domestic TV production and employment.

3.????Domestic consumers will face higher prices for imported TVs and may choose to switch to domestic TVs or substitute with other products. This may lead to an increase in demand for domestic TVs.

4.????The tariff will generate additional revenue for the government, as it will be collected on every imported TV sold in the domestic market.

One example of how international trade and payments can impact a country is the story of China's rise as an economic powerhouse. Over the past few decades, China has become a major player in the global economy, exporting a wide range of goods and services to countries around the world. This has been made possible, in part, by its favorable exchange rate, which has allowed it to offer competitive prices on its exports. As a result, China has experienced rapid economic growth and has become an important trading partner for many countries.

Another example of international trade is Saudi Arabia's reliance on oil exports. Saudi Arabia is the world's largest exporter of oil, with oil exports accounting for roughly 90% of the country's total export revenues (World Bank, 2021).

The reliance on oil exports has had significant impacts on the Saudi Arabian economy:

1.????Oil exports have been a major driver of economic growth in Saudi Arabia. According to data from the World Bank, the country's GDP per capita increased from $3,000 in 1970 to over $20,000 in 2019, largely due to the growth of oil exports (World Bank, 2021).

2.????The oil sector has also been a major source of employment in Saudi Arabia, with roughly one-third of the country's workforce employed in the sector.

3.????However, the reliance on oil exports has also made the Saudi Arabian economy vulnerable to fluctuations in global oil prices. For example, the sharp decline in oil prices in 2014 led to a significant slowdown in the country's economic growth and a rise in unemployment.

4.????In recent years, the Saudi Arabian government has sought to diversify the economy and reduce its reliance on oil exports. This has included initiatives to promote investment in non-oil sectors, such as manufacturing, tourism, and renewable energy.

In summary, the case of Saudi Arabia illustrates the importance of international trade to the economy and the potential risks and challenges associated with relying on exports of a single commodity. It also highlights the need for countries to diversify their economies and explore opportunities in other sectors to reduce reliance on exports and mitigate the risks associated with fluctuations in global demand and prices.

The global trade landscape has undergone significant changes in recent years, including the rise of regional trade agreements, the growth of e-commerce, and the increasing importance of emerging economies in the global economy.        

Hence, international trade and payments are an essential part of the global economy, allowing countries to exchange goods and services and facilitating the flow of money across borders. Exchange rates, international financial institutions, and other factors all play a role in this process, and understanding these dynamics is important for businesses and governments alike. Numerous studies have highlighted the benefits of international trade for both developed and developing countries. For example, a review of the literature by the World Trade Organization (WTO) found that trade liberalization has contributed to higher GDP growth rates in developing countries (WTO, 2019). Similarly, a study published in the Journal of International Economics found that increased trade openness is associated with higher levels of productivity and innovation (Melitz & Redding, 2014).
