Effects on Welfare Brought by Changes in Taxation - Focusing on Low-income Population in America

摘要

Taxations policies have been a controversial topic debated by the government of the US for many years. This article will focus on Obamacare, using analysis of variance, to study trends in the college enrollement rates, employment rates, and marriage stability in the US. Trends in averages demonstrate that college enrollments, employment rates, and marriage stability all increase after the legislation of Obamacare; however, the result of variance analysis proves that changes in these three areas (college enrollments, employment rates, marriage) are not significant. This shows that Obamacare did not significantly improve welfare of the low-income population in the US.
