External Economies Of Scale Occur

Generally the concentration of competitors has been fragmented by geography. However, through recent consolidations, the emergence of regional and national chains has started to prevail along with the decline of the independent/local shops. This consolidation activity has allowed many companies to spread their fixed costs over a wider range of output, thus

Other scale economies can be Multi-Product ES (“Economies of Scope”); indeed, different types of cereals can be produced in a very similar way, not requiring different production facilities, but leveraging the existing ones. The same can also be applied to packaging/bagging, which is the main source of Economies of Scale, because the Big Three use the same

Economies of scale: Large companies can produce products at a much lower cost than small ones because the cost per unit drops as the volume of output rises

International trade affects the economy by increasing the Aggregate Demand (AD), and by becoming a source of inputs for production. International trade based on the theory of comparative advantage will improve efficiency in allocating resources, as well as allow businesses to reach economies of scale - "the situation in which costs per unit of output fall as output increases", consequently reaching competitive prices of international markets (Colander, 2004, p. 428). When an economy involves itself in trade, under the right circumstances, it is able to shift the Production Possibility Curve (PPC) curve outward, and achieve greater levels of output. This increase in production can be achieved through the use of more resources

The impact of economies and diseconomies of scale Tesco face As businesses grow and their output increases, they commonly benefit from a reduction in average costs of production. Total costs will increase with increases in output, but the cost of producing each unit falls as output increases. This reduction in average costs is what gives larger firms a competitive advantage over smaller firms. This fall in average costs as output increases is known as Economies of Scale.

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]

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.

Economic analysts say trading among other countries with no stipulations improve global efficiency in resource allocation (Tupy, 2005). Free Trade delivers goods and services to those who value them most and allows partners to gain from specializing in the producing those goods and services they do best; according to Tupy’s findings, Economists call that the law of comparative advantage. Tupy also states when producers create goods they are comparatively skilled at i.e. Germans producing beer and the French producing wine, those goods increase in abundance and quality. Trade allows consumers to benefit from more efficient production methods, for example, without large markets for goods and services, large production runs would not be economical. Large production runs, in turn, are instrumental to reducing product costs while lower production

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)

Countries are enabled by free international trade to specialise or to focus in the production of the goods in which they have a comparative advantage. Specialisation countries can take the benefit of efficiencies generated from increased output and economies of trade. The size of the firm’s market are increased by the international trade which results in lower average costs and increasing in productivity, as it ultimately leads to increase in production.

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).

Adam Smith, author of The Wealth of Nations, shows support for free trade and emphasises it as a trade policy which ought to be adopted. Krugman and Obstfeld back Smith's support by stating that the efficiency of trade is increased by free trade and accumulates the national income of countries. Free trade is a theory which suggests that each nation benefits in specialising in an economic activity from which it gains absolute advantage, enjoying absolute superiority over other nations in a specif economical activity (Peng). With free trade follows opportunity, replacing regulation and growth of economic activity. (Rugmann and Collinson).

The new trade theory began to emerge in the 1970s when a number of economists pointed out that the ability of firms to attain economies of scale might have important implications for international trade (Wickramasekera, Cronk & Hill 2013). This theory is based on two major concepts that are economies of scale and first-mover advantage. To elaborate:

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).
