Studying international business theories is essential to steer, strategize, and succeed in a globalized economy, enabling professionals to understand complex trade dynamics, manage cross-cultural risks, and identify international growth opportunities. These theories provide the analytical tools needed to optimize supply chains, enhance competitiveness, and formulate effective, sustainable global strategies.

The theories can be classified into: Classical Country-Based Theories: Mercantilism, Absolute Advantage, Comparative Advantage and Heckher-Ohlin Theory. Modern Firm-Based Theories: Country Similarity, Product Life Cycle, Global Strategic Rivalry and Porter’s National Competitive Advantage.

Mercantilism

It is a form of economic system and nationalist economic policy that is designed to maximize the exports and minimize the imports of an economy. It seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.

It is also known as “commercialism,” which is a system in which a country attempts to amass wealth through trade with other countries, exporting more than it imports and increasing stores of gold and precious metals. It is often considered an outdated system.

The biggest example being Passed by the British Parliament in May 1773, the Tea Act was a mercantilist policy designed to bail out the struggling British East India Company by granting it a monopoly on tea sales in the American colonies. It allowed the company to ship tea directly to America, bypassing merchants and reducing costs, while enforcing a three-cent tax to assert Parliament’s taxing authority. The Act aimed to save the financially troubled British East India Company by allowing it to dump 17 million pounds of unsold tea in American markets, creating a practical monopoly.  Ships carrying tea were also turned away or had their tea destroyed in New York, Philadelphia, and Charleston. The Tea Act was effectively the world’s first corporate bailout (often helping by paying money in difficult situation) the act was designed to save the East India Company from bankruptcy.

Mercantilist economic policies rely on government intervention to restrict imports and protect domestic industries. Modern-day mercantilist policies include tariffs, subsidizing domestic industries, devaluation of currencies, and restrictions on the migration of foreign labor.

Modern-day mercantilism in India is reflected in policies prioritizing domestic manufacturing, reducing import dependency, and fostering a trade surplus, often termed “neo-mercantilism” or economic nationalism. Key examples include the Atmanirbhar Bharat (Self-Reliant India) initiative, the Production Linked Incentive (PLI) schemes, high tariffs on imports, and the decision to stay out of the RCEP (Regional Comprehensive Economic Partnership)  trade agreement to protect domestic sectors.

Absolute Advantage

The ability of a country to produce more of a good with the same resources than another country is absolute advantage. India has an absolute advantage in the production of wheat over China and China has an absolute advantage in the production of cloth over India. Absolute advantage in international business occurs when a country can produce more of a good or service with raw material or technology which the country enjoys. It represents superior efficiency due to factors like better technology, climate, or lower labor costs.

Due to abundant oil reserves, Saudi Arabia can produce oil at a much lower cost and in higher volume than most countries, giving it an absolute advantage. China has historically held an absolute advantage in textile production due to a large workforce, lower labor costs, and efficient manufacturing capacity. Japan possesses an absolute advantage in high-end electronics manufacturing owing to its advanced technology and highly skilled workforce.

Comparative Advantage

It is the ability of a country to produce goods at a lower opportunity cost than another country by achieving  economies of scale. Reductions in average costs due to increased production levels. For example, China’s low labor costs give it a comparative advantage as a manufacturer over many Western trading partners. South Africa has a comparative advantage in mining because of its mineral wealth.

Brazil has a comparative advantage in coffee production due to climate, while South Africa holds an advantage in mining due to mineral abundance. Germany and Japan have a comparative advantage in automobile manufacturing and high-end machinery due to advanced technology and highly skilled labor, despite higher production costs. India has a comparative advantage in software development and IT services due to a large pool of educated, English-speaking, and cost-efficient professionals, which the U.S. imports.

Eli Heckscher and Bertil Ohlin Theory

It is also known as factor-proportions theory. Both prepared a theory explaining international trade patterns by focusing on differences in factor like cheap labor, raw material, and capital between countries, suggesting that countries export goods using their abundant, cheaper factors and import goods which are scarce.

Bangladesh specializes in clothing (labour-intensive), while Germany exports machinery (capital-intensive). A country with abundant labor (e.g., India) tends to produce and export textiles, while a capital-abundant country (e.g., Germany) specializes in automobile production. While South Korea was historically labor-abundant, it successfully transitioned to capital-intensive exports (electronics) by investing in infrastructure.

Modern & Firm based theories:

Raymond Vernon’s Product Life Cycle (PLC) theory

This explains how trade patterns shift as products evolve from innovation in developed nations to mass production and standardization in developing countries, moving through introduction, growth, maturity, and decline stages. The theory explains how a product’s production and trade patterns shift over time, eventually leading the original innovating country to become an importer of the very product it invented. As the name suggests, this theory talks about a product that goes through different stages. This theory only focuses on the developed nation, not on the developing nation.  According to this theory, when a product is in its early life cycle stage, all the raw material and the labor used in making and producing that product belong to the place where the product has been invented or produced. But when that new product is introduced in the world market, then its area of origin shifts to different places

PC Personal computer) were introduced to world by US; its mass manufacturing in low-cost Asian countries declined production in US. Now US purchases Pcs from Asian countries.

Country Similarity Theory (Steffan Linder)

Trade within similar development stages (intra-industry trade) occurs due to similar consumer preferences. states that countries with similar income levels, consumer habits, and industrial development trade similar, high-quality manufactured goods with each other (intra-industry trade). Key examples include massive trade in automobiles between Germany and France, or electronics between the US and Canada.

Global Strategic Rivalry (Krugman/Lancaster)

Firms gain competitive advantage through innovation, R&D, and economies of scale, influencing trade patterns. Competition for leadership in semiconductors, artificial intelligence, and 5G networks, often involving sanctions, export restrictions, and investments in critical infrastructure.

Porter’s Diamond Model

National competitive advantage stems from four interconnected factors: factor conditions, demand conditions, related/supporting industries, and firm strategy/rivalry. Germany’s automotive industry, showcasing strong national advantage through skilled engineers (Factor Conditions), demanding consumers wanting high-performance cars (Demand Conditions), a robust supply chain (Related/Supporting Industries), and intense rivalry between BMW, Mercedes, and Audi driving innovation (Firm Strategy/Rivalry).

Understanding and influencing human behavior is crucial for a variety of reasons, people with whom we work every day, deal on regular basis, for our personal growth and strong relationships for effective teamwork and societal progress. Good behavior fosters positive environments, builds trust, and contributes to a safer and more inclusive society. It also impacts mental and emotional well-being and can influence productivity and success in various aspects of life. 

Personality is fixed and it’s difficult to change, so it makes sense to focus our efforts at the point where changes can be made. Since behaviour is within our condition of control, affirmative feedback on behaviour offers a positive lead for personal development, showing where and how we can adapt to meet the needs of a particular situation or job role. Counselling largely helps to change our behaviour.

Behaviorism is a branch of psychology which primarily studies observable actions and responses, rather than internal mental processes like thoughts or feelings. It suggests that behaviors are learned through two main types of conditioning: classical conditioning which is associating stimuli with responses and modified conditioning  which is learning through consequences of behavior. I list here below few famous theories of behaviourism.

John B. Watson’s classical behaviourism

Watson’s theory focused on observable behavior as the primary subject of psychological study, rejecting introspection and mental processes. He believed that behavior is learned through conditioning and can be manipulated by environmental stimuli, emphasizing the role of external factors over internal ones. His experiment famously known as ‘the little Albert experiment’, conducted by John Watson and Rosalie Rayner in 1920, aimed to demonstrate that fear could be conditioned in humans through classical conditioning. The experiment involved a nine-month-old baby, Albert, who was initially not afraid of a white rat. Researchers repeatedly paired the rat with a loud, startling noise, causing Albert to associate the rat with the noise and eventually fear the rat itself. The white rat was initially a neutral stimulus, meaning Albert didn’t have an innate fear of it. The loud noise was the unconditioned stimulus, which naturally caused fear in a way the unconditioned response in Albert. 

Watson argued that only behaviors that can be observed and measured objectively are valid in scientific psychology. He believed that behaviors are learned through conditioning, where provocations in the environment are paired with responses, leading to learned associations. Watson rejected the study of thoughts, feelings, and other internal mental processes, arguing that they are not directly observable and therefore not suitable for scientific study. Watson emphasized the role of environmental factors in shaping behavior, suggesting that individuals can be trained to exhibit specific behaviors through conditioning. 

B.F. Skinner’s Reinforcement Theory

Skinner’s behaviorism theory, also known as radical behaviorism, suggests that all behavior is learned through interactions with the environment, primarily through reinforcement and punishment. This theory emphasizes observable behaviors and argues that internal mental states like thoughts are not relevant for understanding behavior. Skinner’s work focused on challenging conditioning, where behaviors are modified by their consequences. It is built on the assumption that behaviour is influenced by its consequences. Reinforcement theory is the process of shaping behavior by controlling consequences of the behavior. Reinforcement theory proposes that you can change someone’s behaviour by using reinforcement, punishment, and elimination. I give here example of Abraham Lincoln who was the president of the United States in a pivotal moment during the Civil War. Although he was assassinated before completing his term as president, the relentless work ethic and unmatched communication skills that Abraham Lincoln showcased while healing the fractured country made him one of the greatest leaders in U.S. history.

Pavlov’s theory of Classical Conditioning

This is rooted in the idea that behavior is the result of conditioning. He believed that behavior is learned through the process of classical conditioning, where behavior is shaped through the association of stimuli in the environment. His discoveries provided a framework for understanding how behaviors are acquired. His experiments primarily involved dogs, but the principles he discovered have far-reaching implications for understanding human behaviour as well. Classical conditioning, the foundation of Pavlov’s theory, involves pairing a neutral stimulus with an unconditioned stimulus to elicit a conditioned response. In one of his famous experiments, Pavlov observed that dogs naturally salivated when presented with food, an unconditioned stimulus. However, through repeated pairings of a neutral stimulus, such as a bell, with the food, the dogs eventually began to associate the bell with the arrival of food. As a result, they started salivating at the sound of the bell alone, even in the absence of the food. This conditioned response demonstrated the formation of a new association between the neutral stimulus and the unconditioned stimulus. Mental conditioning is a process which depends on experience, it takes efforts of training your mind to modify your thoughts, attitudes, and beliefs to accept thinking patterns.

Erikson’s theory of psychosocial development

This theory proposes that behaviourism develops through eight stages, each marked by a unique milestone, crisis or challenge that individuals must manage through. These crises involve a struggle between opposing forces, such as trust vs. mistrust, autonomy vs. shame and doubt, initiative vs Guilt, Industry vs inferiority , identity vs Role Confusion, intimacy vs Isolation, Generativity vs Stagnation and Ego Integrity vs Despair. When individuals successfully resolve each crisis, it leads to the development of specific virtues and psychological strengths, while failure can result in difficulties in future stages Our early life experience is very important in terms of  how we grow as individuals.  Our identity evolves at various stages of life; how we perceive and present ourselves throughout our lives, as per our own sense of identity; we keep searching and understanding ‘who we are’. Understanding this process can lead people to question their ‘negative’ identity labelled by society. Half of life is spent in making big changes in the way we perceive ourselves.  Our personalities keep changing as we resolve crises in life; thus, each experience brings a change within us.

Thorndike’s theory of connectionism

This theory suggests that learning is the result of forming connections between stimuli and responses. This theory, developed by Edward Lee Thorndike, is a foundation of behaviorism, explaining learning as a “stamping in” or strengthening of S-R bonds. Thorndike’s work also established three key laws of learning: the Law of Readiness, the Law of Exercise, and the Law of Effect. Thorndike’s theory of connectionism, also known as stimulus-response (S-R) theory, suggests that learning involves forming connections or associations between stimuli and responses. These connections, or bonds, are strengthened by satisfying consequences and weakened by unsatisfying ones. Thorndike’s theory is based on his experiments with cats in puzzle boxes, where he observed that learning occurred through trial and error. The key aspects of Thorndike’s connectionism are i) learning occurs through the formation of connections between a stimulus – something that triggers a response and a response  which is a behavior or action. Ii) Learning is a process of trying different responses until the correct one is found and rewarded. Iii) Behaviors followed by satisfying moments are strengthened, while behaviors followed by annoying consequences are weakened. Iv) Frequent practice strengthens connections, while lack of practice weakens them.  V) When an individual is ready to act in a particular way, a response is likely to follow. 

Jerome Bruner’s theory of cognitive development

This theory states that children construct their own learning through organising, categorising and then coding information. He believed that the most effective way to do this is to discover information rather than being told it by a teacher. Jerome Bruner’s theory of cognitive development emphasizes that learning occurs through three modes of representation: enactive, iconic, and symbolic. These modes represent how individuals process and represent knowledge, changing with age with mental and physical development. Bruner believed that children could learn difficult concepts with appropriate instruction, and that learning is a continuous process, not a series of stages. They say children are mirror image of their parents and surrounding. Enactive mode, prevalent in early childhood around 0-3 years, involves learning through direct action and manipulation of objects. For example, a baby might learn about size by comparing different-sized colour crayons. The iconic mode starts around 3-7 years; children begin to use images and mental representations to represent experiences. They might use drawings or pictures to recall events or objects. From about 7 years onward, children develop the ability to use symbols, like language, to represent and organize information. They can understand and use abstract concepts without needing a real visual. Bruner believed that development is a continuous process, not a series of distinct stages. 

Conclusion

In simple terms, Sigmond Freud’s theory suggests that human behavior is influenced by unconscious memories, thoughts, and urges. This theory also proposes that the psyche comprises three aspects: the id, ego, and superego. The id is entirely unconscious, while the ego operates in the conscious mind. Behaviorism is primarily associated with the belief that all behaviors are learned through interactions with the environment. It focuses on observable actions, emphasizing the role of stimuli and responses, and rejects the study of internal mental processes. Key figures in behaviorism include John B. Watson and B.F. Skinner. 

Leadership is something that cannot be ignored in an organization, in government, in educational institutions, in hospitals, in police, in society and in army. Anywhere in world, even in animal kingdom it matters. Leadership is deeply ingrained in the human experience and therefore the study of leadership theory gives us a better understanding of the dynamics of leadership, which in turn makes it easier for us to be better leaders or team players. It’s a glaring fact that people don’t leave organizations, they leave their bosses. Friends, poor behaviors of people in command drive away talent which costs hugely to the organizations.

Leaders come in many shapes and sizes. They present many styles, many levels of experience and many levels of competencies. Some are great, while some are bland, while others are absolutely awful. The great leaders have taken us from a starting point to somewhere better.  Some have leaded us through lapses in judgment and confidence; some have leaded us through the unknown to the known; some have supported us when we were having personal difficulties and turmoil. And, there are also those bland leaders who have done nothing, they were insipid and couched. We hardly remember what they did …

Then there are those awful leaders who instead of giving us, taken away from us everything. They reduced our confidence, our abilities, our performance, our enjoyment everything. These worst leaders highlighted our little mistakes, they ridiculed us, and they are scoundrels. So please try to figure out what is your leadership style.

Though theories seem like an alien concept sometimes, leadership theories cannot be ignored.  It is a primal, natural part of human behavior therefore, it is given academic attention. The first step in the path to studying this field is the understanding of what the theory demand. It runs into the field of social science, psychology, part organizational theory, phylosphy and anthropology. It takes a little emotional awareness, and a little philosophical groundwork. I wish to quote here Chester Bernard’s definition in 1938; he says “Leadership is the ability of a superior to influence the behavior of subordinates and persuade them to follow a particular course of action”. I think this is an apt definition on leadership.

Nelson Mandela’s magnificent autobiographical bestseller, ‘’Long Walk to Freedom’’, is a best example of leadership communication. It’s not surprising, then, that such documents attract so much interest when they are made public. People are naturally curious to know about their leader’s personal life, their making, their philosophy etc. Unfortunately, they can occasionally be disappointed as demonstrated in Bill Clinton’s effusive and generally unrevealing autobiography, ‘My Life’ and that leaders are not free from weaknesses in Mahatma Gandhi’s biography ‘The story of my experiments with truth’. Let me tell you friends, people can see leadership; the good, the bad and the ugly; it is not difficult at all. Biographies transport us to other times and places, they teach us essential lessons, they inspire us and show us what we have in common with the center personality.

You ask anyone “what do effective leaders do?” and you’ll hear a sweep of answers. Leaders set strategy; they motivate; they create a mission; they build a culture. But how do they do that? The mystery of what leaders ought to do in order to spark the best performance from their people is their style of leadership. In recent years, you will so many leadership experts, trainers, institutes literally making business, all in pursuit of creating leaders. The world is hungry even today for genuine leaders. There is a dearth of them.

Some of the basic theories will explain all that you want to know about leadership.

The Great Man Theory:  During the 19th century, the Great Man Theory of Leadership was invented and it became very popular. The theory was formulated mainly by analyzing the behaviors of mainly military figures of the time. In the 1800s, authoritative positions were held solely by men and were typically passed on from father to son. Thus, it’s not a fluke that the theory was named “Great Man Theory.” The fact worth noting here is there weren’t any women who were given the chance to rise those days. The famous historian, Thomas Carlyle was deeply involved with this Great Man Theory of Leadership and had even stated that the history of this world was basically the combined biographies of these great men. Mr. Thomas Carlyle believed that effective leaders were a package of ‘Godly’ motivation and the right personality.

Early research on leadership was based on the study of people who were already great leaders. These people were often from the aristocracy, as few from lower classes had the opportunity to lead. This contributed to the notion that leadership had something to do with breeding. Around the mid 19th century, nobody could identify with any scientific certainty, which human characteristic or combination was responsible for identifying great leaders. The Great Man theory assumed that the traits of leadership were inherent. That simply meant that great leaders are born, they are not made. This theory saw great leaders as those who were destined by birth to become a leader. Furthermore, the belief was that great leaders will rise when confronted with the appropriate situation. But, in 1860, Herbert Spencer, an English philosopher disputed the great man theory by affirming that these heroes are simply the product of their times and their actions which results from social conditions. In other words, society was shaping these great men as oppose to them shaping society.

The Trait Leadership Theory: The trait model of leadership is based on the characteristics of many leaders; both successful and unsuccessful and is used to predict leadership efficiency. The resulting lists of traits are then compared to those of potential leaders to assess their probability of success or failure. The trait leadership theory believes that people are either born or are made with certain qualities that allow them to excel in leadership roles. Qualities such as intelligence, sincerity, hard work, responsibility, creativity and other values puts anyone in the shoes of a good leader. Francis Galton was influenced by Thomas Carlyle’s work. He took this idea further. Galton found that leadership was a unique property of extraordinary individuals, and suggested that the traits which leaders possessed were indisputable and could not be developed. Throughout the early 1900s, the study of leadership focused on leadership traits. The trait theory of leadership focused on analyzing mental, physical and social characteristic in order to gain more understanding of what is the characteristic or the combination of characteristics that are common among leaders. In the 1930s the field of Psychometrics was just introduced and it has gained a lot of popularity; personality traits measurement was not so reliable; study samples were of lower rank managers; explanations weren’t offered as to the relation between each characteristic and its impact on leadership. Many studies have analyzed the traits among existing leaders in the hope of uncovering those responsible for ones leadership abilities, but in vain, the only characteristics that were identified among these individuals were those that they were slightly taller and slightly more intelligent. Can you imagine? I wish to mention here that even today after almost two centuries this is one of the best topics for PhD dissertation.

Behavioral theory of Leadership: It assumes that leaders can be made, rather than are born. And, that successful leadership is based in definable, learnable behavior. In reaction to the trait leadership theory, the behavioral theories are offering a new perspective, one that focuses on the behaviors of the leaders as opposed to their mental, physical or social characteristics. Thus, with the evolutions in psychometrics, notably the factor analysis, researchers were able to measure the cause and effects relationship of specific human behaviors from leaders. From this point forward anyone with the right conditioning could have access to the once before cream of the crop naturally gifted leaders. In other words, this theory is based on leaders are made not born. The behavioral theories first divided leaders in two categories. Those that were concerned with the tasks and those concerned with the people. Throughout the literature these are referred to as different names, but the essence are identical.

Behavioral theory is a big leap from Trait Theory, in that it assumes that leadership capability can be learned, rather than being inherent. This opens the floodgates to leadership development, as opposed to simple psychometric assessment that sorts those with leadership potential from those who will never have the chance. The behavioral theory is relatively easy to develop, as you simply assess both leadership success and the actions of leaders. With a large enough study, you can then correlate statistically significant behaviors with success. You can also identify behaviors which contribute to failure, thus adding a second layer of understanding.

Contingency theory of Leadership: The Contingency Leadership theory argues that there is no single way of leading and that every leadership style should be based on certain situational parameter, which signifies that there are certain people who perform at the maximum level in certain places; but at minimal performance when taken out of their element. This theory also claims there is no best way to organize a corporation, to lead a company, or to make decisions. Instead, the optimal course of action is contingent (dependent) upon the internal and external situation. A contingent leader effectively applies his/her personal style of leadership to the situation. To a certain extent contingency leadership theory is an extension of the trait theory, in the sense that human traits are related to the situation in which the leaders exercise their leadership. It is generally accepted within the contingency theories that leader are more likely to express their leadership when they feel that their followers will be responsive.
