Introduction When analyzing other systems that promote free trade and trade in various ways, you need to consider the 360-degree view of all the advocacy and derogatory factors of each style. There is no perfect competition or constant innovation; due to the nature of the economy, these are factors that can never be realized. The fact is that "economists do not have reliable models" (Krugman, 1987, p. 139), which truly reflects economic behavior. However, in order to build a theory, it is necessary to establish such assumptions, prove the viewpoint, and present new ideas on ancient problems.
"Free trade is not outdated, but this idea has lost its innocence so unrecoverably" (Krugman, 1987, p. 132).

Classical trade theory is driven by comparative advantage and is based on continuous size and complete competition, which supports free trade. - INTRODUCTION When analyzing other systems that promote free trade and trade in various ways, you need to consider the 360-degree view of all support and insult factors of each style.

Although this approach supports the existence of trade rather than trade, it begins to shake free trade as the only answer to international economic theory. Therefore, government intervention does not always succeed, but it is now the standard of international trade. However, as Krugman pointed out, "In the world characterized by increased revenue and incomplete competition, budget constraints still exist.
