Productivity assessment has received increased attention over the past several years. At the same time, the focus has moved from single-factor productivity measures, or attempts to characterize performance in terms of simple ratios, to a multi-factor construct. In this dissertation, I propose a...

Purpose: This paper aims to explore the influence of information technology (IT) capability (i.e. IT exploration and exploitation) on service innovation and ultimately financial performance in manufacturing firms. Moreover, this paper examines the contingent role of cross-functional integration...

Purpose: This study examines whether consumer brand engagement (CBE) can mitigate the negative effects of economic animosity (EA) on purchase intention (PI) and strengthen the positive effect of country-of-origin (COO) on PI. Design/methodology/approach: Using questionnaires distributed to 372...

The paper studies the result of Zhu21 and establishes a relationship between the efficiency in data envelopment analysis (DEA) and the pareto optimality under multiple objective linear programming (MOLP). It is shown that the DEA/preference structure models in Zhu21 can be derived by traditional...

Data envelopment analysis (DEA) identifies an empirical efficient frontier of a set of peer decision making units (DMUs) with multiple inputs and outputs. The efficient frontier is characterized by the DMUs with an unity efficiency score. The performance of inefficient DMUs is characterized with...

The demand for petroleum has risen rapidly due to increasing industrialization and modernization of the world. The limited reserve of the fossil fuels is also dwindling alongside escalation in the prices. The threats from these and food insecurity are, however, drawing the attention of...

The conventional data envelopment analysis (DEA) assumes that the inputs and outputs are real values. However, in many real world instances, some inputs and outputs must be in integer values. While integer-valued DEA models have been proposed, the current paper develops an integer-valued DEA...
