In this paper we consider inference procedures for two types of dynamic linear panel data models with fixed effects …. First, we show that the closure of the stationary ARMA panel model with fixed effects can be consistently estimated by the … conditional AR(1) panel model with fixed effects under various asymptotic plans. Then we show that when N tends to infinity but T …

To create their rankings, university-ranking agencies usually combine multiple performance measures into a composite index. However, both rankings and index scores are sensitive to the weights assigned to performance measures. This paper uses a stochastic dominance efficiency methodology to...
