The American economy is expected to boost by 3.1 percent this year due to increase in government expenditure and tax reductions supported the growth, according to the Congressional Budget Office yesterday. However, the strong expansion may slow down earlier in 2019 considering that the United States may weaken as temporary government policies may elapse based on CBO’s report. Moreover, the Congressional Budget Office predicted showed that the economic growth will decline to 2.4 percent next year and 1.7 percent in 2020, hovering above that level on the following decade. In case that CBO’s figures coincided with the results, the US economy would likely leap to 3.1 percent this year versus 2.6 percent last year. The mentioned numbers indicate a significant development amid the impact of the Great Recession, with a slackening annual growth rate of 2.2 percent.
