We extend the Tauer (2001) and Färe et al. (2004) analyses of aggregation bias in technical efficiency measurement to multiple criteria decision analysis. We show input aggregation conditions consistent with multiple criteria evaluation of overall efficiency in conjunction with variation in...

The results of an experiment with simulated data show that combining inputs with different criteria (as cost, material inputs aggregates and other) increases the accuracy of the Data Envelopment Analysis (DEA) technical efficiency estimator in data sets with dimensionality problems. The positive...

The results of an experiment with simulated data show that using multiple positive lineal aggregators of the same inputs instead of the original variables increases the accuracy of the Data Envelopment Analysis (DEA) technical efficiency estimator in data sets beset by dimensionality problems....

In this paper Sato’s two-level CES production function has been estimated by nonlinear regression carried out through five different methods of optimization, namely, the Hooke-Jeeves Pattern Moves (HJPM), the Hooke-Jeeves-Quasi-Newton (HJQN), the Rosenbrock-Quasi-Newton (RQN), the Differential...

This study investigates the factors influencing the adoption of blockchain technology in logistics in Vietnam, focusing on customer perspectives. Utilizing the Technology Acceptance Model (TAM), the research examines key determinants such as attitude, perceived ease of use, perceived usefulness,...

As Africa’s major oil exporter and factor driven stage country, Nigeria has made some progress in socioeconomic terms in recent years. However, large pockets of Nigeria’s population still live in poverty without adequate access to basic services. Currently, Nigeria is capturing just as small...

This paper examines the behaviour of disaggregated output over the economic cycle in South Africa. Aggregate output and output of the economic sectors and industries were decomposed into their transitory and potential components. These components were then examined for comovement. The results of...

As the most populous nation in Africa, Nigeria is uniquely positioned to reap the benefits of the emerging digital economy. And by accelerating access to digital technologies spurs innovation, efficiency and productivity which brings about choice and opportunities for greater growth and...
