The vast majority of the efficiency and productivity measurement literature has been based on the static viewpoint of … the firm. Few studies have developed the dynamic analog of static efficiency measurement, introducing the notions of long …-run efficiency and inefficiency persistence. However, these few existing dynamic efficiency studies have not provided any empirical …

function framework was carried out, looking at the following components: technical change, change in technical efficiency …

In this paper we merge techniques from the efficiency literature with spatial econometric techniques. In particular, we … combine calculation of efficiency from the unit speci c effects with the spatial lag model to develop a spatial autoregressive … frontier model for panel data. Features of the modeling include time-varying efficiency and estimation of own and spillover …
