Kesenjangan ekonomi: Perbedaan antara revisi

Kesenjangan ekonomi bervariasi tergantung masyarakat, waktu, struktur ekonomi, dan sistem. Istilah tersebut dapat mengacu pada persebaran pendapatan atau kekayaan lintas lapisan masyarakat pada waktu tertentu, atau pendapatan dan kekayaan seumur hidup dalam jangka panjang.<ref>Wojciech Kopczuk, Emmanuel Saez, and Jae Song find that "most of the increase in the variance of (log) annual earnings is due to increases in the variance of (log) permanent earnings with modest increases in the variance of transitory (log) earnings." Thus, in fact, the increase in earnings inequality is in lifetime income. Furthermore, they find that it remains difficult for someone to move up the earnings distribution (though they do find upward mobility for women in their lifetime). See their "Earnings Inequality and Mobility in the United States: Evidence from Social Security Data since 1937," ''Quarterly Journal of Economics''. 125, no. 1 (2010): 91–128.</ref> Ada beberapa [[indeks (ekonomi)|indeks]] numerik untuk mengukur kesenjangan ekonomi. Di antara [[metrik kesenjangan pendapatan|metode pengukuran kesenjagan]] yang ada, [[koefisien Gini]] merupakan indeks yang paling terkenal.
