Talk up or criticize? Customer responses to WOM about competitors during social interactions

Popular metrics such as the Net Promoter Score (NPS) highlights many benefits of word of mouth (WOM) to firms. Is WOM all it is claimed to be? Building on social identity theory, this research develops a conceptual model of WOM exchange in social settings and tests the model with customer surveys of three service sectors. The findings show that the effects of (1) positive and negative WOM (P/NWOM) received about competitors and (2) perceived presence of critical incidents (PPCIs) on P/NWOM given about own service provider are far from intuitive. Responses to PWOM received counter the suggestions in the NPS literature. The findings also indicate that the best firms can hope for when receiving NWOM about competitors is that their customers remain silent. It is recommended that firms communicate a message that is consistent with the nuanced views expressed by friends in social circles, rather than a uniformly superior positioning.     

An accounting revolution? The financialisation of standard setting

This paper analyses the political-economic content of the recent ‘revolutionary’ shift in financial accounting rules for listed companies, specifically the rise of IFRS and fair value. It connects this shift to the socio-economic changes that are currently being discussed in the literature on financialisation, e.g. the rise of shareholder value and the proprietary view of the firm. Two ideal-typical accounting systems are constructed on the basis of normative accounting theory and extant standards – historical cost accounting (HCA) and fair value accounting (FVA). The ‘accounting revolution’ of the past 10–15 years can be understood as a qualitative shift from HCA to FVA. It is further argued that these ideal-typical systems are related to different circuits or forms of capital – productive and money capital respectively – and to the particular perspective that these afford on the, capitalist firm. Inasmuch as financialisation is related to the circuit of money capital one can make sense of the rise to prominence of FVA, which represents the dominance of a financial view of the firm in the field of financial accounting. Throughout this paper, however, the limits to financialisation are also highlighted and traced back to the ineradicable manifestation of the circuit of productive capital.     

Towards an understanding of excel functional skills needed for a career in public accounting: Perceptions from public accountants and accounting students

Public accounting firms (e.g., Grant Thornton, 2012) are stressing an interest in recruiting accounting students with a proficiency in Excel. The purpose of this study is to investigate which Excel functions are perceived to be important and useful for new hires to understand prior to starting a job in public accounting. We collect survey data from four large public accounting firms as well as undergraduate and graduate accounting students (i.e., potential new hires) to gauge perceptions of Excel importance, knowledge, and usage in public accounting. We find that employees at the firms believe the most important Excel functions are: basic formula, filter and sort data, vertical (horizontal) lookup, formatting of documents, and If/Then statements. In a comparison of new hires at public accounting firms with accounting students, results suggest that accounting students underestimate the importance and usage of some of these Excel functions. In addition, results suggest that new hires’ perceived knowledge on how to use specific Excel functions in their accounting job is statistically different than students’ perceived knowledge on how to use some of the same Excel functions. Our research contributes to educational accounting literature by documenting which Excel functions employers in public accounting want new hires to know prior to starting a job in public accounting. Also, this research informs accounting educators that students’ perceptions are not the same as public accounting employers’ expectations with respect to analytical skills using Excel technology.     

America's “exceptional” transition to capitalism: A counter view

This paper is a response to part two of Rob Bryer's (RB) analysis of the development of capitalism in the US, focusing on the second half of the 19th century when the nation was transformed into the world's largest industrial power. We argue that RB's view that America became a capitalist economy only post-1900 is counterintuitive given the scale of output, the rate of acceleration, and the accumulation and concentration of capital prior to that date.     

CIOs' perspectives of critical success factors in ERP upgrade projects

Enterprise resource planning systems have required significant upgrades in the 21st century as many of the systems obtained prior to 2000 have become outdated due to vendor changes. SAP and Oracle have emerged as dominant vendors, and SAP has announced discontinuance of support in the future for its primary R/3 system. This study reports interviews with the chief information officers (CIOs) of 15 institutions that have undergone (or are undergoing) enterprise system upgrades, with focus on discussion of major critical success factors for ERP upgrade projects.

Critical mass of users versus critical mass of services in a multiproduct information service system

In this paper we study the economic behaviour of the suppliers of a set of advanced telecommunications services with a joint adoption cost (common access facilities, learning process, etc.). In fixing the two-part tariffs for their services the suppliers have to share the burden of leaving to the users a surplus sufficient to cover the adoption cost. The lack of coordination in supplying a critical mass of services or in the pricing decisions has high changes to result in suboptimal or unviable diffusion of the new technology as a whole. We present a static optimization model of user behaviour, and derive access and usage demand with a two-part tariff and a joint adoption cost. We compare noncooperative and cooperative market equilibria in a duopoly with perfect information; finally we discuss the extension of our analysis to the case of imperfect information in a dynamic setting.     

基于收入分布的收入差距扩大成因的分解

本文采用核平滑化的半参方法估计了1987年、1996年、2004年我国城市居民收入分布曲线,并且基于收入分布又进一步分解了导致城市居民收入差距扩大的主要原因。收入差距扩大的成因可以分为两类:一是劳动者的劳动力特点的普遍变化,如劳动者教育水平的提高,行业、职业分布的变化;二是对劳动力特点回报率的变化,如教育回报率的提高,各行业、职业回报率差异的扩大等。本文发现后者是导致收入差距扩大的主要原因。
