Data envelopment analysis (DEA) is a linear programming methodology to evaluate the relative technical efficiency for each member of a set of peer decision making units (DMUs) with multiple inputs and multiple outputs. It has been widely used to measure performance in many areas. A weakness of...

Purpose: This paper aims to investigate the internal and external determinants of firms’ efficiency and develop optimal corporate governance risk benchmarks for the manufacturing sector across different countries. Design/methodology/approach: Corporate governance risk data were acquired from...

The experiments were performed using a modified six-cylinder turbocharged direct injection diesel engine with diesel of different distillation ranges to investigate the effects of (exhaust gas recirculation) EGR on engine performance and emission characteristics of low-temperature combustion...

Economic activity produces not only desirable outputs but also undesirable outputs. Undesirable outputs are usually omitted from efficiency assessments (i.e., applications of Data Envelopment Analysis) which fail to express the true production process. The directional distance function model has...

The cost escalations in PEs and health expenditures were concurrent with GDP growth. TPE has been the major source of financial burden for patients. Even though the rapid growth in China’s economy may ameliorate the overall TPE burden, control of PEs is still a key for successful health system...
