In the past few years, one of the most misunderstood concepts is income disparity. Income inequality issues are now a concern for the public. However, it was heightened by the recession in 2008-09, resulting in consequences for the corporate sector, the Occupy Wall Street movement, Covid-19 pandemic and a myriad of other events. This book analyzed how income disparity is rising with higher income distribution margins witnessed among the highest earners. This book has thirteen chapters, eliminating the introductory overview chapter, on income disparity, poverty, and economic well-being. These chapters were authored by academics who publish articles on these issues on a regular basis. The literature on these issues is substantial, and research interest in these topics has a long history. Furthermore, it is fairly unusual for academics' viewpoints on these subjects to disagree. In light of this, the subjects of the articles may best be regarded as representing the contributors' different viewpoints. Graduate students and professional researchers will also find these guides an excellent contribution to supplemental teaching in economic fields, especially labor economics, macroeconomics, and economic policies.
