Analyzing Intra-Industry International Trade

Introduction

Intra-industry trade (IIT) is the trading of similar products belonging to the same industry between countries. Unlike traditional trade theories that highlight inter-industry trade based on comparative advantage, IIT shows a more in-depth landscape where countries export and import similar products, often characterized by the same industry. This research paper will explore the foundations of intra-industry trade, economies of scale, monopolistic competition, global oligopoly, agglomeration economies, and a case study that illustrates these concepts in practice.

Economies of Scale

Companies can achieve economies of scale by increasing production while lowering per-unit production costs. Costs can be both fixed and variable (Kenton, 2024). As a company produces more products, the average cost per unit will go down. This can be seen as cost advantages that companies experience when they increase their production levels.

For example, a large car manufacturing company can use automation in assembly lines, thus largely reducing labor costs and increasing production speed. Furthermore, in managerial economies, big companies can have the resources to hire specialized managers for specialized tasks, leading to more efficient management and operations compared to smaller companies where managers would be required to bear multiple responsibilities and roles. As for financial economies, companies usually have easier access to capital and can get loans at lower interest rates due to perceived lower risk by banks. This financial advantage allows them to invest in growth and innovation.

Economies of scale are an essential element in economics that highlights how companies can lower costs and improve productivity as they grow. Larger companies can produce more by spreading the cost of production over a larger amount of goods (Kenton, 2024). By knowing the types and uses of economies of scale, companies can create tactical strategies that leverage these advantages to improve their competitive edge in the market.

Monopolistic competition and the Gravity Model of Trade

Having knowledge of market structures and trade elements is essential in order to  analyze how companies operate and how products are exchanged internationally. The gravity model of international trade states that the volume of trade between two countries is proportional to their economic mass and a measure of their relative trade frictions (Bair & Standaert, 2020). Two essential concepts in this context are monopolistic competition and the Gravity Model of Trade.

Monopolistic Competition

Monopolistic competition is a market structure characterized by a large number of companies that sell products that are similar but not identical. This structure is often seen in retail, food service, and consumer goods. Companies in a monopolistically competitive market provide differentiated products. This differentiation can be a result of several factors such as quality, branding, features, or customer service. In monopolistic competition, companies are price makers. This would mean that they can set prices above marginal cost but will lose customers if prices are set too high. Monopolistic competition encourages variety in products that can benefit consumers with diverse products to choose from.

The Gravity Model of Trade

The Gravity Model of Trade is used to predict trade flows between two countries. The model is named for its analogy to Newton’s law of gravitation, which states that larger masses attract each other with greater force. Distance between countries has a big impact on how often and how much they trade because the distance between countries affect transportation costs, and trade barriers. In other words, the greater the distance, the lower the expected trade volume between the countries. Some trade costs are likely attributable to government policies like higher tariffs, economic sanctions, and other forms of regulations likely raise the cost of trading and hence reduce trade. Free trade agreements, on the other hand, are typically designed to lower trade costs and boost trade (Bair & Standaert, 2020). Furthermore, trade agreements can lower barriers and transportation costs, which influence both monopolistic competition and trade flows. In addition, geography, cultural and historical factors can influence trade costs. (Bair & Standaert, 2020).

Monopolistic competition and the Gravity Model of Trade are the fundamental concepts in market dynamics and international trade. Monopolistic competition encourages product differentiation so that companies can provide diverse products that cater to consumer preferences. On the other hand, the Gravity Model allows companies and governments to predict trade patterns based on economic size and distance. The correlation between these two concepts shows how complex global trade is and how market structures encourage trade flows and economic relationships between countries.

Global oligopoly (Strategic Trade Policy)

Some industries are dominated by other larger companies which can be known as oligopoly. Strategic Trade Policy is defined as government policy which attempts to shift excess profits in an oligopolistic international markets towards the home country firms (Berkeley University, n.d). This market domination can result to strategic relationships among companies. An oligopoly exists when a small number of companies hold significant market share in an industry. These companies actions have a direct effect on the other companies. Such industry can include the pharmaceutical industry as it is an example of an oligopolistic market where a small number of companies are in competition for market dominance.

High barriers to entry like the need for a large amount of funds to launch and operate, patents, and economies of scale, can usually protect large companies and prevent new competition. Strategic trade policy comes into play as governments attempt to grow the competitive position of domestic companies in oligopolistic industries.

A strategic trade policy is used to assist domestic industries by imposing tariffs on foreign products. This allows for governments to protect local companies from foreign competition, allowing them to gain market share. In oligopolistic markets, companies can influence prices because of the market share they have over a specific industry. However, such tactics can result in retaliatory measures from other countries that would then result in trade wars. Hence, While strategic trade policy can offer advantages it can also come with complex challenges. As the global economy continues to evolve in a rapid pace and the internet allows us to be more connected than ever before, understanding the fundamentals and effects of oligopoly and strategic trade policy will continue to become essential for policy makers and companies.

Agglomeration Economies (External Economies of Scale)

Agglomeration economies refer to the benefits that companies and the people obtain when they are near each another. To understand external economies of scale, first lets examine internal economies of scale, which come from elements within a company. These can be further subdivided into several categories such as technical, managerial, financial, and marketing. Internal functions include accounting, information technology, and marketing, which are also considered operational efficiencies and synergies. (Kenton, 2024). As production increases, companies can spend more capital for more advanced technologies that smaller companies cannot afford.

In contrast to internal economies, external economies of scale occur outside a company but within an industry. That means no one company control costs on its own (Kenton, 2024). This can lead to the benefits to be shared by all companies in a region. For example, As an industry grows, supporting businesses like suppliers also grow. Furthermore, As industries cluster in specific regions, governments that spend capital in infrastructure developments would benefit all companies in that area. 

Additionally, external economies of scale occur within an industry involves how a cluster of companies in a specific region may contribute to the growth of talented employees. Some example include places like New York for fashion, San Francisco for tech startups, and Los Angeles for actors. Along with all the benefits, agglomeration economies also comes with challenges. As companies and people move to agglomerated areas issues such as overcrowding, traffic congestion, and increased living costs can come up. The challenges that come with agglomeration need to be addressed in order to have sustainable growth. By having regions that collaborate and innovate, specific cities can position themselves as competitive players in the global economy and attract top talent from all over the world due to their big city reputation.

Case Study

An example of intra-industry trade is the European automobile industry, where countries like Germany, France, and Italy work in exchange of similar vehicle models. Germany is the biggest exporter of automobiles in the world and with a strong global reputation for producing high-quality and technologically advanced vehicles, they exported $135B worth of Cars (Inspexion.com, 2023). The European Union's market facilitates this trade by removing tariffs and regulatory barriers. German automakers like BMW and Mercedes-Benz export luxury vehicles and also import parts from countries like France and Italy. The competitive element leads to a variety of models that cater to large diverse consumer wants and needs. This case shows how economies of scale, market structure, and agglomeration economies factor into intra-industry trade.

Conclusion

Intra-industry trade questions the conventional perspectives on international trade by highlighting the importance of economies of scale, market structures, and strategic trade policies. As countries exchange similar products, understanding intra-industry allows for understanding the fundamental elements which drive the global trade outcomes. The interplay between monopolistic and oligopolistic competition, along with agglomeration economies, creates the landscape of intra-industry trade, which encourages innovation. The case of the European automobile industry highlights these elements, showing the complexity of modern trade. As globalization continues to grow and develop, the importance of intra-industry trade is surely to grow and would require additional research and analysis to stay up to date with the modern world.
