A short note on discrimination and favoritism in the labor market
(Te Herenga Waka—Victoria University of Wellington, 2016) Salamanca, Nicolas; Feld, Jan
We extend Becker’s model of discrimination by allowing firms to have discriminatory and favoring preferences simultaneously. We draw the two-preference parallel for the marginal firm, illustrate the implications for wage differentials, and consider the implied long-run equilibrium. In the short-run, wage differentials depend on relative preferences. However, in the long-run, market forces drive out discriminatory but not favoring firms.

Students are Almost as Effective as Professors in University Teaching
(Te Herenga Waka—Victoria University of Wellington, 2019) Feld, Jan; Salamanca, Nicolas; Zolitz, Ulf
In a previous paper, we have shown that academic rank is largely unrelated to tutorial teaching effectiveness. In this paper, we further explore the effectiveness of the lowest-ranked instructors: students. We confirm that students are almost as effective as senior instructors, and we produce results informative on the effects of expanding the use of student instructors. We conclude that hiring moderately more student instructors would not harm students, but exclusively using them will likely negatively affect student utcomes. Given how inexpensive student instructors are, however, such a policy might still be worth it.
