We compare non-blind teacher assessments with blind national test scores in maths to examine teacher-test score disparities by children's height and weight. Relative to test scores, shorter and heavier children are rated less favourably by teachers. This teacher-test score discrepancy cannot be...

We study the impact of Economic Policy Uncertainty (EPU) on the US Economy by using a VAR with time-varying coefficients. The coefficients are allowed to evolve gradually over time which allows us to discover structural changes without imposing them a priori. We find three different regimes,...

We propose a general framework for Maximum Likelihood (ML) and Bayesian estimation of income distributions based on grouped data information. The asymptotic properties of the ML estimators are derived and Bayesian parameter estimates are obtained by Monte Carlo Markov Chain (MCMC) techniques. A...

Students' out-of-school activities and time use can play a crucial role in facilitating school effectiveness. Using data from Seoul, South Korea, where the assignment of students into schools is random, we show that single-sex high schools affect the out-of-school activities of boys only, while...
