Introduction
Since the 2008 financial crisis, economists have been blamed for their incapability to predict the collapse of the financial system with economic models. It has been widely debated about the role of economic models, in particular their underlying assumptions and their ability to predict the upcoming events. Colander et al pointed out that unrealistic assumptions plays a main role in the failure of economic models (Colander et al 2009: 7-10). Opponents would invariably point their fingers towards Friedman’s ‘Methodology of Positive Economics’; where he proposed that the validity of assumptions is totally irrelevant when evaluating economic models, only the usefulness of prediction matters.
Nonetheless, when evaluating economic models, we should take into account the description, explanation and understanding of the world. In this essay, by using the Ricardian model as an example, I will illustrate that even if one only cares about the prediction, we should also address the importance of assumptions, which would then lead us to explore the true purpose of science.
The Ricardian Model
The Ricardian trade model is a simple yet powerful theory that refutes common fallacies about the causations of trade flows. It illustrates that, instead of absolute advantage, it is comparative advantage that brings forth the gains from trade. Comparative advantage refers to the ability to produce a product at a lower opportunity cost than another. This ability is the result of
According to Colander, "The reason two countries trade is that trade can make both countries better off" (2004, p. 416). In economics, the theory of comparative advantage clarifies why it can be advantageous for two countries to trade, even though one of them may be able to produce every kind of item more cheaply than the other. What matters is not the absolute cost of production, but instead, the ratio between how easily the two countries can produce different kinds of goods. The basic idea of the principle of comparative advantage is that as long as the relative opportunity costs of producing goods differ among countries, then there are potential gains from trade.
If each country specializes in areas where its advantages are greatest or disadvantages are least, the gains from trade will make each country better off than it would be if it remained self-sufficient. [3]
Due to the differences between the countries in its profitable fundamentals; the International Trade occurs. The contracts between the countries consider as the primary driver of the global exchange. These contracts concluded on the basis of the countries beneficial elements and advantages. Each international trade between the countries depends on numerous focal points of this exchange process. The economics and producers effectiveness measured by absolute advantage for these economics/producers. For example; if the producer needs lesser amount of contributions/inputs to provide specific product, then this producer has an absolute advantage in producing
"Home movies are about innocence--our lost fuzzy, glowing personal pasts, all horseplay, and funny hats and the promise of youth" (Cooper, 23). Andrew Jarecki's remarkable film, Capturing the Friedmans captured just what is clearly a case study of extreme family dysfunction through such home videos. At first Andrew Jarecki just wanted to do a nice little documentary about clowns. He decided to try film making and thought he would cut his teeth on something easy like birthday party clowns. He had met David Friedman a top childrens birthday party clown from Manhattan, New York. Much to his surprise David

However, it was apparent to economists that nations with similar resource endowments exchanged similar products with each other. Economists felt that trade explained solely by comparative advantage was an incomplete analysis of international trade. Furthermore, since the classical trade theory was unable to explain intraindustry trade, economists decided to expand on the classical trade theory by creating a new theory of trade (Carbaugh, 2011). The new theory states that economies of scale provide incentive for a country to specialize in a particular product (Carbaugh, 2011). Furthermore, based on economies of scale, nations with similar factor endowments will trade with each other as sometimes it is beneficial (Carbaugh, 2011). Arguments stemming from this new trade theory puts the economic case for free trade in doubt.
Which is cost difference determines the patterns of international trade. Absolute advantage is trade benefits when each country is at least cost producer of one of the goods being traded. In the 1800s, David Ricardo developed the theory of comparative advantage to measure gains from trades. This theory is based on comparative advantage and it states each nation should specialize in production of those goods for which its relatively more efficient with a lower opportunity cost.
The country can maximize their wealth by putting the resources in the most competitive industries. Government created comparative advantage rather than free trade because now easier moves the production processes and the machines into countries that can produce more goods (Yeager & Tuereck, 1984). However, many countries now move to new trade theory suggests the ability firms to limit the number of competitors associated with economic scale (reduction of costs with a large scale of output) (Krugman, 1992). The comparative advantage occurs when two-way trade in identical products, it will useful where economic scale is important, but it will create problem with this model. As a result, government must intervene in international trade for protection to domestic firms (Krugman, 1990)
Since the mid-20th century, countries have progressively reduced barriers, subsidies to domestic industries and diverse restrictions on international commerce in order to promote specialization and greater efficiency in production. In theory, free trade allows nations to focus on their main comparative advantages and profit from cooperation and voluntary trade. This strategy is usually reinforced by treaties between two or more countries where commerce of goods and services can be handled across their common borders, without tariffs and other trade obstacles. As a key component of regional integration in the Americas, CAFTA-DR is one important example of this economic ideology.
Trade freedom is a highly important factor in determining economic freedom and wealth. No one single country has the resources required to sustain the current standards of living in developed or developing nations. Trade requires specialization according to a country’s comparative advantage. Specialization allows the most efficient and effective use of a country’s scarce resources, whether that be natural resources or labor resources. The Index shows the economic benefits of specialization and trade.
The theory of comparative advantage explains the benefit of free trade. According to this theory by David Ricardo in the early 19th century, “Both countries will be better off if each specializes in the industry where it has a comparative advantage, and if the two trade with one another.” (Citation) International trade opens up markets to foreign supplier, and domestic companies need to improve their efficiency, boost productivity, and lower cost to increase competitiveness instead of enjoying monopolies or oligopolies that enabled them to keep prices well above marginal costs. On the other hand, international trade also offers domestic companies bigger demands and broader markets; therefore more jobs relevant to export have been created. Furthermore, jobs in the US supported by goods exports pay 13-18 percent more than the US national average (ustr.gov).
The classical model also known as the Ricardian model argued that countries trade because of differences in their technology however, the Heckscher-Ohlin (HO) is a factor-proportions theory of comparative advantage idea which argues that the idea of comparative advantage works under the influence of relative factor abundance and relative factor insensitivity (Suranovic, 2006).
The international trade of goods across the world accounts for approximately 60% of the world Gross Domestic Product (The World Bank, 2014). A great proportion of goods transactions occur every second. The primary question is whether international trade benefits a country as an entirety, and, if so, why would a country implement protective trade policies to restrict particular exports? To address this question, this essay aims to explore the impact of trade on various economic stakeholders, including consumers, producers, labour and government and, furthermore, will compare models and theories with reality to ascertain the true winner/ loser in the international trade market.
The concept of absolute advantage is one of the most fundamental areas of concern in the study of economics. In its basic meaning, absolute advantage refers to the ability of one individual or party to produce more of a particular good or service than other competitors given the same amount of resources. In this regard, absolute advantage becomes a very important aspect in the concept of international trade as it clearly defines the different areas where countries should specialize in order to maximize their productivity and enhance international trade. The principle of absolute advantage was first elucidated by Adam Smith in his study of international trade using labor and capital as the only factor inputs(Free, 2010).
The principle of comparative advantage provides a simplified theory explaining why free trade is possible, even when one country has an economic disadvantage. Both the Ricardian and Heckscher-Ohlin theories rely on fixed economic assumptions of constant return and perfect competition. However, intuitively the basic principle of business is to increase returns through innovation, improving processes and technology or increasing economies of scale. Organizations understand they control pricing and are price setters, rather than price takers as suggested by perfect competition (Krugman & Obstfeld, 2003). The idea of increasing returns and imperfect competition challenge the foundations of comparative advantage.
