Abstract

Integrally, the informal sector deals with the formal sector with pro-cyclical nature or as a complementary sector. Such conditions allow for wage disparity between sectors even in the same education group. Thus, this study seeks to determine the determinants of wage inequality between formal and informal employees in skilled and unskilled workers in Indonesia in 2017 using Blinder-Oaxaca decomposition. The results showed that the discrimination factor had a greater influence than the endowment factor on wage inequality and the endowment factors that contributed to the increase in wage inequality between the two groups were age squared, experience, and job training.

Bahasa Abstract

Secara integral, sektor informal berhubungan dengan sektor formal dengan sifat pro-siklikal atau sebagai sektor pelengkap. Keadaan demikian memungkinkan terjadinya kesenjangan pendapatan antarsektor meskipun dalam kelompok pendidikan yang sama. Sehingga, penelitian ini berusaha untuk mengetahui pengaruh karakteristik pekerja terhadap ketimpangan pendapatan antara karyawan formal dan informal pada pekerja terampil dan tidak terampil di Indonesia tahun 2017 menggunakan dekomposisi Blinder-Oaxaca. Hasil penelitian menunjukkan bahwa faktor diskriminasi berpengaruh lebih besar dibandingkan faktor endowment terhadap kesenjangan pendapatan dan faktor endowment yang berperan dalam meningkatkan kesenjangan pendapatan kedua kelompok tersebut adalah usia kuadrat, pengalaman, dan pelatihan kerja.
