Companies that generate revenue could recruit more labour and perhaps increase dividends paid to shareholders. This money is distributed several times by the economy, as a result of what economists call the multiplier effect of money, which says that for every dollar an individual receives as income, part is spent (i.e. consumption) and part is saved. If individuals save 10 per cent of their income, 90 cents will be spent on each $1 and 10 cent income. The 90 cents that are then spent are paid for another person, and another 90 per cent of them are spent on consumption. This will continue until there is nothing left of the original $1. While removing trade barriers is generally a step towards free trade, there are situations where a reduction in tariffs can effectively increase the effective protection rate for a domestic industry. Jacob Viner cites an example: “Suppose there are import duties on both wool and wool, but despite duty no wool is produced at home. The abolition of the obligation of wool on the wool shroud without this being important for wool farming. [11] One of the most well-known defenders of this philosophy, known as mercantilism, was Thomas Mun, a director of the British East India Company. In a letter written to his son in the 1630s, he said: “The ordinary way to increase our wealth and treasure is foreign trade, and we must never respect that rule.

more to sell to foreigners each year, that wee consume their value. . . . This order has been properly maintained in our trade, . . . . .

that a portion of our stock that is not returned to us in goods must necessarily be developed us.” [1] In the analysis of the impact of a surplus or deficit, economists often consider “trade” very far in the definition. In general, economists do not consider simply the balance of trade in goods, such as the “current account balance,” which includes the trade balance of goods and services, as well as net income from international income (profits transferred from foreign investments, royalties, interest and dividends) and unilateral transfers (foreign aid and transfers of individuals to be relevant). With the exception of unilateral transfers, all of these elements are included in our trade agreements. Few issues divide economists and the scope of public opinion as much as free trade. Studies show that economists at U.S. university faculties are seven times more likely to support a free trade policy than the general public. In fact, the American economist Milton Friedman said: “The economic profession was almost unanimous on the question of the desire for free trade.” In fact, there are, of course, other reasons than trade barriers, why factors of production such as capital or labour cannot cross borders, even if there are no barriers and higher yields could be achieved in other markets. Workers, for example, are reluctant to leave their homes, their family and friends, and investors are reluctant to invest in other markets where they are less familiar. As a result, even removing all state-imposed barriers to capital and labour trade would not lead to full compensation for costs between counties.

In some circumstances, trade negotiations with a trading partner have been concluded, but have not yet been signed or ratified. This means that, although the negotiations are over, no part of the agreement is yet in force. The Heckscher-Ohlin model, which is likely to project likely trade patterns between countries with different factors of production, has really not explained this trade pattern. Krugman`s theory is based on product differentiation and economies of scale. A jeep and a Volkswagen, for example, are both automobiles, but they are very different from the consumer era.
