This paper advances the concept of scale elasticity by examining the impact of directional
input changes on both desirable and undesirable outputs. We integrate two disposability …

The aim of this study is to provide approaches to analyse the performance of two-stage
processes under managerial disposability and to address their scale elasticity where there …

Under the current universal trend towards larger grant sizes in research funding systems, we
focus on how large of a grant size is appropriate. We study the directional returns to scale …
