The risk in using financial reports in the study of airline business models

A review of published articles has shown that many researchers use financial reports as the main source of information in regard to airline business models. A study of accounting policies and other external information, however, has highlighted the differences in assumptions as to useful lives and the residual values of aircraft, which are the principal assets of airlines. While the considerable, unexplained differences in the accounting policies of enterprises with similar business models indicate there may be risk in using this data, the risk can be eliminated by making appropriate adjustments in the financial statements.     

Relevance,responsibility, critical performativity,testimony and positive marketing: contributing to marketing theory,thought and practice

In this commentary, I chart recent changes at the Journal of Marketing Management (JMM). These include the introduction of a senior editorial board, a revised main editorial board and a modified team of associate editors. The new deputy editor is welcomed. The exemplary performance of the JMM in scholarly league-tables is registered. From this, a case is made for the pluralisation of the concepts of relevance and impact. In doing so, the emergent literature on critical performativity is unpacked. I highlight a missed opportunity in this material, namely, the potential for academics to act as critical commentators on industry practice in the courtroom. Developing the ideas associated with critical performativity leads to the scrutiny of new concepts in marketing. One of importance is positive marketing. This regressive manoeuver is critiqued; as is macromarketing narcissism. Following Dunne et al., I make a plea for more responsible academic practice. Developing logically from these ideas, a number of new potential avenues for contributing to the JMM are sketched. These include special sections and research notes among others.

通过研究架构理论,分析了消费品制造企业在"互联网+"背景下的架构创新。提出变换外围要素、核心要素相同的二阶中性置换可以形成两种不同的消费品制造企业架构创新模式。经过改进的双层技术接受模型检验,两种模式的结果殊途同归,预测两种模式结合的双层架构创新模式会成为未来新型消费品制造企业架构创新的主流。     

Assessing the competition in Angola’s banking industry

This article analyses the level of competition in Angola’s banking industry using the Panzar–Rosse model with data from 2005 to 2014. Competition is a vital aspect of the banking market and therefore it is central to policy-making. The results reveal that Angola banking competition is monopolist and therefore lower competition is found in Angola banks. Policy implication is derived.     

Exchange rate,marginal q and investment behaviour of small and medium-sized enterprises in Japan: time series evidence of manufacturing industries

In this article, we investigate Granger’s causality among the exchange rate, Tobin’s marginal q and investment-capital ratio with quarterly data on firms categorized as small and medium-sized enterprises (SMEs) in Japan. We utilize the data of the following industries: chemical, iron and steel, production machinery, electric machinery and equipment, automobile and accessories and all manufacturing. The empirical results we obtain show that the null hypotheses of no Granger’s causality from the exchange rate to other variables, investment and marginal q, are accepted in all industries. The reason is the lower percentage of export by SMEs. Thus, it is considered that the effects of Abenomics on SMEs are limited, and that other kinds of reflation measures for SMEs are needed.     

Robust grain supply chain design considering post-harvest loss and harvest timing equilibrium

This paper presents a bi-level robust optimization model, where a food company maximizes its profit and minimizes post-harvest loss by optimally deploying grain processing/storage facilities and determining grain purchase price, while a group of spatially distributed non-cooperative farmers determine harvest time, shipment, storage, and market decisions under yield uncertainty and market equilibrium. The non-cooperative behavior of the food company and the farmers is represented by a bi-level Stackelberg leader follower’s game model with mixed-integer decision variables. The proposed model and solution approach are applied to case studies for Illinois and Brazil.     

Optimal transit fare and service frequency of a nonlinear origin-destination based fare structure

This paper proposes a new nonlinear distance-based transit fare structure, which is measured by a function of the Euclidean distance between the origin and destination stations, termed as Origin-Destination (OD)-based fare. The novel fare structure encourages passengers to freely choose the most efficient trip plan. An optimization model is formulated based on a three-party game (involving the transport authority, transit company, and passenger) to determine the optimal fare function and frequency. An artificial bee colony algorithm is adopted to solve the model. Finally, a numerical example is provided to verify the proposed method.     

Willingness to pay: Who are the cheap talkers?

The purpose of this paper is to determine who is willing to pay (WTP) for a greener event by applying a Contingent Valuation (CV) approach together with an experimental design. To identify the cheap talkers a survey was conducted at the Wacky Wine Festival in South Africa, were 474 respondents participated. Using a Heckman two-step approach, the results confirmed that the decision to contribute depends on behavioural and motivational factors, while the amount is income-dependent. The extent of cheap talking is significant, with a 50% deviation in stated and revealed behaviour. Besides cheap talkers, another category is identified, namely “ethicals”, who contribute their voucher to the tree planting project without indicating that they are willing to pay.     

Advancing destination image: The destination content model

Knowledge of the mental representations that individuals hold about tourist destinations are important to understand their intentions. These mental destination representations have often been investigated by applying the concept of destination image. This study argues that the extant literature is often rather atheoretical and lacks operational rigor. These are major shortcomings which undoubtedly hinder the development of academic and managerial insights. In response, this study draws on contemporary psychology to develop the destination content model, comprising three informational components held in individuals‘ minds about destinations. The present study further outlines preferable methods and measures for each component, thus aiding researchers to investigate mental destination representations.     

社会交往、旅游情境对旅游需求的影响研究--基于春节“黄金周”的实证分析

以往关于消费者需求行为的研究多基于传统经济学框架的设定展开，认为影响消费者旅游需求的主要因素包含收入、目的地吸引力、交通等，普遍忽视了消费过程中的社会交往和具体情境。文章在理论分析的基础上，提出了若干命题，将消费者收入、社会交往和旅游情境等因素纳入旅游消费者需求的模型中，提出了若干研究命题。依据2014年春节“黄金周”旅游需求调研数据，采用排序选择模型验证了相关命题的正确性。计量结果表明，个人经济因素对我国消费者春节“黄金周”旅游需求影响较小，家庭结构、同伴等社会交往因素是影响其旅游需求的重要因素；我国消费者对于春节“黄金周”出游过程中遭遇的拥堵、旅游市场混乱等旅游情境问题具有一定的容忍度，但是，严重供需失衡导致的旅游情境问题依然对其旅游需求产生了显著的影响。
