With the improvement of people's living standards all over the world, the demand for cooling (both space cooling and refrigeration) continues to grow. The increase in cooling-related energy consumption has a growing impact on global climate change. The importance of improving the energy...

This paper investigates the social-welfare efficiency drivers of public university hospitals in Brazil by focusing on how the surrounding social welfare conditions may affect their performance. A novel Genetic Envelopment Analysis (GEA) approach is developed here to this end. Subsequently, LASSO...

Traditional retailers (bricks-and-mortar) have been continuously increasing online sales. However, not all retail companies were able to respond to the increasing sales with the same efficiency level as their competitors. This paper aims to propose a dynamic model - incorporating principles of...

In this paper, we introduce an unsupervised machine learning method for production frontier estimation. This new approach satisfies fundamental properties of microeconomics, such as convexity and free disposability (shape constraints). The new method generalizes Data Envelopment Analysis (DEA)...

This research investigates the relationship between efficiency and firm growth as well as the relationship between firm growth and market structure (CR4) to evaluate whether the quiet-life (QL) and/or efficient structure (ES) hypothesis applies in the Indonesian palm oil industry. This study...

The article focuses on evaluating the technical efficiency of garlic production in northwest Ethiopia. The average yield in the region was lower than its potential, indicating a need to improve farming practices. Data were collected from 359 garlic producers using random sampling. The...

Our study investigates the influence of information and communication technology (ICT) applications at the national level on the efficiency of Islamic banks (IBs) and conventional banks (CBs) operating in Gulf Cooperation Council (GCC) countries. We analyze data collected from both CBs and IBs...

The increasing violent episodes in Mexico suggest a worrying trend. What is more, worrying the majority of the Mexican population is their perception of insecurity and desperation.
