While countries around the globe have increased spending on health care, economists and policy makers have raised concerns over the productivity and efficiency of health care. This article applies a stochastic frontier approach to address this issue using data from 141 countries for the period...

In this paper, we study Lp-error estimates for a scheme proposed by Zhao et al. (2006) for solving the backward stochastic differential equations . We prove that this scheme is of second-order convergence for solving for yt and of first-order convergence for solving for zt in Lp norm. And we...

Biodiesel has potential as a substitute for petroleum diesel because of the increasing worldwide concern for environmental sustainability and dwindling petroleum resources. Methanol has been the commonly used alcohol for biodiesel production. Compared with methanol, ethanol can be derived from...

Purpose Drawing on dynamic capability theory, this study investigates how online–offline channel integration (OOCI) affects a firm's supply chain resilience and how such an effect is moderated by market turbulence and regulatory uncertainty. Design/methodology/approach A sample of 273 Chinese...

Purpose Using dynamic capability theory, this study investigates how information technology (IT) support affects firms' online and offline cross-channel integration (CCI). In addition, it applies institutional theory to examine how the relationships between IT support and CCI are moderated by...

Purpose This paper aims to address the issue of model discontinuity typically encountered in traditional Denavit-Hartenberg (DH) models. To achieve this, we propose the use of a local Product of Exponentials (POE) approach. Additionally, a modified calibration model is presented which takes into...

We establish a theoretical model to explain the relationship between the regional technical efficiencies and production location choice. A higher regional technical efficiency level attracts foreign direct investment (FDI) and offsets the adverse effects of a high wage rate and setup cost. Data...

This paper considers the mean variance portfolio management problem. We examine portfolios which contain both primary and derivative securities. The challenge in this context is due to portfolio's nonlinearities. The delta-gamma approximation is employed to overcome it. Thus, the optimization...

Purpose – The purpose of this paper, taking banking as the research object, is to build up a psychology covenant model for service enterprises and customers and to seek the form of the construction dimension in the psychology covenant between the service enterprise and the customer....

Purpose For strategic and competitive insights, the purpose of this paper is to measure and benchmark the comparative operating efficiencies of Association of Southeast Asian Nations’ (ASEAN) major airlines and present a new interpretation along with managerial implications....
