A contribution to the linear programming approach to joint cost allocation: Methodology and application
2009
Abstract The linear programming (LP) approach has been commonly proposed for joint cost allocation purposes. Within a LP framework, the allocation rules are based on a marginal analysis. Unfortunately, the additivity property which is required to completely allocate joint costs fails in presence of capacity, institutional or environmental constraints. In this paper, we first illustrate that the non allocated part can be interpreted as a type of producer’s surplus. Then, by using the information contained in the Simplex tableau we propose an original two-stage methodology based on the marginal costs and the production elasticity of input factors to achieve an additive cost allocation pattern…
Conjoint Analysis as an Instrument of Market Research Practice
2007
The essay by the psychologist, Luce, and the statistician, Tukey (1964) can be viewed as the origin of conjoint analysis (Green and Srinivasan 1978; Carroll and Green 1995). Since its introduction into marketing literature by Green and Rao (1971) as well as by Johnson (1974) in the beginning of the 1970s, conjoint analysis has developed into a method of preference studies that receives much attention from both theoreticians and those who carry out field studies. For example, Cattin and Wittink (1982) report 698 conjoint projects that were carried out by 17 companies included in their survey in the period from 1971 to 1980. For the period from 1981 to 1985, Wittink and Cattin (1989) found 66…
Main drivers of consultancy services: A meta-analytic approach
2016
Abstract This meta-analysis incorporates the results from 34 separate studies examining fee models for consultancy services whereby the consulting firm provides both audit and advisory services to its customers. The findings indicate a number of key determinants of consultancy bills: client size, audit fees, auditors being from a “Big Audit Firm,” client's financial difficulties, and prior experience with the legal auditors. Conversely, the meta-results fail to correlate the variable of interest with several constructs commonly used in consultancy models such as the auditee's inherent risk, the client's financial debt, or the audit opinion. The study also explores the influence of three mod…
A conjoint analysis of customers' preferences for e-banking channels
2021
Internet has transformed the manner in which banks interact with the customers. The purpose of the paper is to measure customers' preferences towards different channel attributes namely: internet banking, mobile banking and payment portals at a composite level that reflect the relative importance of usage attributes, i.e., payment type, transaction size, motivation to use and rate of urgency. Conjoint analysis was applied to estimate utilities for these attributes and to determine the existence of consumer groups with similar preference profiles. Furthermore, our study shows that the most preferred combination of utilities are customers preference to use payment portal, for 'paying bills' o…
A review of negotiation outcome: A proposal on delimitation and subsequent assessment in joint venture negotiations
2009
Abstract In this study, we examine the outcomes of negotiation processes in joint ventures. Following a review of negotiation and strategy literature, we propose that satisfaction with the relationship created between partners is the most suitable indicator of negotiation outcome. This indicator is analyzed through the use of two parameters or variables: trust and uncertainty. The analysis is then used to bridge the gap that currently exists in the literature by proposing when a negotiation should be considered successful in joint ventures. One important conclusion of our study is that nonagreement should not always be valued in negative terms as in certain circumstances it can imply the mo…
Dynamics of the termination of global alliances: probing the past, analyzing the present and defining the frontiers for future research
2022
PurposeWhile the number of global alliance terminations in the business world has grown steadily during the past few decades, the scholarly literature on strategic alliance (SA) termination remains limited. This research paper aims to perform a bibliometric analysis of the literature on alliance termination and propose a model for future research agenda that links the termination phase to the pre-alliance termination phase and post alliance termination phase.Design/methodology/approachA search query on global alliance termination identified a total of 69 research papers from the Scopus database, and a bibliometric analysis was performed using the bibliometrix R-package and VOSviewer. The an…
Accelerating Causal Inference and Feature Selection Methods through G-Test Computation Reuse
2021
This article presents a novel and remarkably efficient method of computing the statistical G-test made possible by exploiting a connection with the fundamental elements of information theory: by writing the G statistic as a sum of joint entropy terms, its computation is decomposed into easily reusable partial results with no change in the resulting value. This method greatly improves the efficiency of applications that perform a series of G-tests on permutations of the same features, such as feature selection and causal inference applications because this decomposition allows for an intensive reuse of these partial results. The efficiency of this method is demonstrated by implementing it as…
ℓ1-Penalized Methods in High-Dimensional Gaussian Markov Random Fields
2016
In the last 20 years, we have witnessed the dramatic development of new data acquisition technologies allowing to collect massive amount of data with relatively low cost. is new feature leads Donoho to define the twenty-first century as the century of data. A major characteristic of this modern data set is that the number of measured variables is larger than the sample size; the word high-dimensional data analysis is referred to the statistical methods developed to make inference with this new kind of data. This chapter is devoted to the study of some of the most recent ℓ1-penalized methods proposed in the literature to make sparse inference in a Gaussian Markov random field (GMRF) defined …
A lap joint simulant laboratory test method of aluminium alloys
2015
A lap joint simulant cavity (LJSC) with a gap thickness of 200 μm has been developed to test corrosion of assembled coated aluminium alloys. The LJSC was instrumented with electrodes allowing simultaneous pH and potential measurements in 0.5 M NaCl solution. Assuming the outer part of the LJSC is electrochemically inactive (painted sheet) it was confirmed that in free corroding conditions the pH inside the LJSC tends more towards alkalinisation. On the opposite, if the outer part of the LJSC is electrochemically active (unpainted sheet) the pH inside the LJSC tends towards an acidic value.
Static strength and fatigue life of optimized hybrid single lap aluminum–CFRP structural joints
2017
Hybrid bolted/bonded joints are used to assemble structural components, commonly made by carbon fiber reinforced plastics (CFRP), with aluminum frames. Hence, they have become common solutions in a number of modern structural applications in the industrial fields, as well as civil constructions. Unfortunately, due to the lack of understanding of the relationships between the multiple parameters of influence that characterize their mechanical performance, only limited improvement have been achieved so far over classical bonding approaches, in terms of static and fatigue strength. As a result, further studies are needed in order to better exploit the potential of hybrid bolted/bonded joints a…
