We compare several income distributions in urban China in the late 1980s and mid-1990s using tests for stochastic dominance in order to decompose gender differentials. Examination of the entire distribution gives insight into the uniformity of such differentials across the distribution....

The American School Counselor Association (ASCA) recommends that there be no more than 250 students to each school counselor. Although numerous studies in the education literature show that school counselors play a positive role in educating children, to our knowledge, this is the first study...
