The present study investigates the effect of obesity and overweight on children's cognitive abilities and well-being using survey data from West Bank schools. The results show the significant adverse impact of obesity on a child's well-being by raising externalizing (behavioral) problems and increasing the probability of classifying a child with…

Academic feedback has a direct impact on students' effort decisions and academic performance. However, the grades that are reported to students are often based on institutional or instructor preferences, with entities adopting a discrete or fine grading scale. In this study, we utilize a field experiment to assess how a Letter (LGS) or Numerical…

As such, researchers should be cautious when interpreting differences in the numerical size of…
