Perhaps this was the motivation to carry out this study in order to analyze different aspects of the crisis and its repercussions on the U.S. and global economy, and then to gauge the impact of the crisis on the economies of some countries. The study found that the crisis has affected most countries of the world and at all levels (the financial sector, the real sector, the business sector, the household sector, etc.). And that entailed a crisis of food and fuel and the high cost of housing prices, raw materials and others.
