An alternative approach for the panel second stage of data envelopment analysis (DEA) is presented in this paper. Instead of efficiency scores, we propose to model rankings in the second stage using a dynamic ranking model in the score-driven framework. We argue that this approach is suitable to...

We construct a new family of chance constrained directional models in stochastic data envelopment analysis, generalizing the deterministic directional models and the chance constrained radial models. We prove that chance constrained directional models define the same concept of stochastic...

In the innovation literature, little attention has been paid to technical efficiency as a measure of performance, despite the fact that technical efficiency is key to explaining firm productivity. In this study we analyze the influence of internal R&D, external R&D and R&D cooperation on the...

Good practice suggests that budget allocations should reflect spending priorities and that spending should provide cost-effective delivery of public goods and services. This paper analyzes the composition of public expenditure in the Slovak Republic. It also assesses the relative efficiency of...

This study investigates the relationship between production efficiency in financial intermediation and financial system size. The study predicts and tests for the existence of ""systemic scale economies"" (SSEs), whereby value-maximizing intermediaries operating in large systems are expected to...
