A current account surplus or deficit may be affected by the economic cycle. Therefore, if our economy grows rapidly, the demand for imports will increase, as consumers can afford to buy more and businesses will need parts and stocks to grow. Similarly, U.S. exports are influenced by the economic growth of its trading partners. In short, if it grows faster than its trading partners, it will have a negative impact on the U.S. current account. Conversely, this will have a positive effect on the current account if U.S. trading partners grow faster. A second extremely important reserve is the so-called factor price adjustment rate, which states that international trade will compensate for relative factors of production. B such as unskilled labour, between countries under free trade conditions. This would mean that for a high-wage country such as the United States, wages for unskilled workers would fall, while wages would rise in labour countries. However, factor prices will not tend to offset in sectors where production costs are falling.
A country can also adopt a beggar-thy-neighbor attitude by deliberately using the terms of trade in its favour by introducing an optimal tariff or manipulating currencies. In his economics manual, Dominick Salvatore defines an optimal tariff as one of the great strengths of these models, which can show how the impact on the n-Adurchin industry was reflected in the economy as a whole. One of their drawbacks is that because of their complexity, the assumptions underlying their projections are not always transparent. Economic models are useful in giving an idea of what might happen as a result of a trade agreement. They give the impression of being authoritarian, but users need to be aware that economic models do not predict what is really going to happen and that they have significant weaknesses. Almost all Western economists today believe in the desire for free trade, and this is the philosophy championed by international institutions such as the World Bank, the International Monetary Fund and the World Trade Organization (WTO).
