We first, analyze, and measure how air public policies influenced the technical efficiency of Latin American privatized airports in a context of structural reform still in progress. Second, we study how the COVID-19 pandemic impacted the technical efficiency of the privatized airports in the...

The existing cross-efficiency evaluation methods under network structures are all limited to two basic network systems: series and parallel. Based on the directional distance function (DDF), we firstly propose the cross-efficiency evaluation method for a parallel two-stage system, which consists...

The paper analyzes properties of a large class of ``path-based'' Data Envelopment Analysis models through a unifying general scheme, which includes as standard the well-known oriented radial models, the hyperbolic distance measure model, and the directional distance measure models. The scheme...

This paper explore the role of institutions to enhance the productivity growth across countries using a two stage Double Bootstrap Data Envelopment Analysis (DEA). The productivity growth is calculated on the basis of Malmquist productivity index. It also explores the sources of productivity...

This paper specifies an empirical framework for estimating both technical and allocative efficiency, which is applied to a large panel of European banks over the years 1996 to 2003. Our methodology allows for self-consistent measurement of technical and allocative inefficiency, in an effort to...

COVID-19 has stimulated additional research interest on economic sustainability and ESG in both academia and industry. This study adopts a DEA approach to examine the efficiency of achieving ESG targets and their relationships with financial performance. Using MSCI ESG data from 2015-2019 on...

In goals-based wealth management (GBWM), an investor looks to maximize the probabilities of attaining each of n goals over time. Because the goals are in competition for potentially limited financial resources, their relative importance must be specified, which we do by assigning utility weights...
