A Comparison of Clustering Dynamics in the British Broadcasting and Financial Services Industries

This paper compares patterns of industrial clustering in the British broadcasting and financial services industries. Recent trends of deregulation, rapid technological change, and globalization in both industries suggest the significant and increasing importance of clustering effects. This study examines the evidence. It investigates the effects of cluster strength on the growth of the firm and on rates of surviving entry. We find positive, large, and statistically significant clustering effects. In both industries: (a) incumbent firms located in a cluster that is strong in their own sub-sector of their industry tend to grow faster than average; and, (b) new firms are attracted by industry strength in certain sub-sectors in a particular region. The results for these largely mature service industries are very similar to those observed in earlier studies that have examined clustering patterns in newer high technology manufacturing industries.     

The Move to the Middle: Convergence of the Open‐Source and Proprietary Software Industries

In this paper we focus on open‐source software within the broader framework of the software industry. More specifically, we compare proprietary and open‐source software (OSS) companies in terms of three criteria: (a) approaches to the production of software; (b) business models; and (c) strategic interactions. We postulate three convergence hypotheses. First, there is evidence of convergence in production approaches: leading OSS firms tend to rely on R&D and acquisitions as intensely as leading proprietary companies do. Second, there is evidence of convergence in business models: through dual‐licensing models, top OSS firms derive substantial portions of their revenues from licenses, just as many proprietary companies do. Third, there is evidence of convergence in strategic interactions: the competitive strategies that a company follows do not really hinge on the ‘proprietary versus open‐source’ dichotomy, but on whether a firm feels threatened in the software layer where its core assets are located. This evidence of convergence raises a number of interesting questions for economic theory and for the analysis of the industry’s future evolution.     

Assessing the Performance of ‘Inflation Targeting Lite’ Countries

This paper deals with what is referred to in the literature as the ‘Inflation Targeting Lite’ (ITL) countries. These are a category of emerging countries, whose main characteristics are that they are least developed and small economies that pursue IT. They use inflation targeting to define their monetary policy framework, but for a number of reasons they are not in a position to put top priority to IT in relation to other objectives. This paper deals with a set of ITL countries for which consistent data could be gathered, and for which a date for setting inflation targeting could be discerned. The object of the paper is to study the impact of IT on actual inflation and inflation expectations. We utilise intervention analysis to time series on inflation for a number of ITL countries, which have actually implemented IT. In doing so our main concern is to assess whether, due to the IT intervention, there has been a significant change in the trend corresponding to these series and the extent to which inflation rates have actually been ‘locked‐in’ at low levels after the implementation of IT. Two major results emerge. The first is that ITL countries have been successful in ‘locking‐in’ inflation rates. The second is that non‐IT countries have also been successful in terms of the ‘lock‐in’ effect. Our overall conclusion, then, is that other factors in addition to IT underpin the apparent success of the control of inflation.     

Information Technology and Establishment Size in America: Rybczynski Redivivus☆

The Rybczynski Theorem is one of the staples of international trade theory. In their article in this issue of the journal, J.J. Rosa and J. Hanoteau apply the theorem to a two-by-two world in which the two “industries” are small firms and large firms, and the two inputs are information and all other. The assumption that small firms are more information intensive, coupled with the fact that information has become pervasive in recent decades, allows them to derive the prediction that small firms will account for increasingly larger proportions of total output and employment in the economy. We highlight a couple of issues that we find problematic in the Rosa–Hanoteau study, and then develop two different empirical strategies to probe the connections between IT and the size distribution of establishments. First, we combine County Business Patterns with input–output data to explore whether the share of small plants has grown at a faster pace among industries that demand IT more heavily. Second, we explore, on an industry-by-industry basis and taking into account the potential endogeneity of IT location, whether clustering of IT firms in specific US counties is associated with a relatively large share of small establishments, on average, in those counties.     

The continuing debate on firm performance: A multilevel approach to the IT sectors of Taiwan and South Korea

In the economics and strategy fields, researchers seek to understand the antecedents of firm profitability. How and why do certain private enterprise firms develop competitive advantages in environments of rapid technological change while other firms do not? This study extends recent variance decomposition research in three ways. First, this work compares IT sectors in Taiwan and South Korea by using the Standard & Poor's Compustat® Global Vantage database. Second, this investigation tests industry and firm effects using both the multilevel approach of hierarchical linear modeling (HLM) and the conventional variance components approach (VCA). Third, this study explores the question of why there are significant profitability differences among technological firms even with similar industrial structural characteristics and leveraged resources and capabilities in the same IT industry. This study uses data from the U.S. Patent Office to estimate technological diversification at the level of firm resources for knowledge-based relatedness for the IT firms of Taiwan and South Korea. The empirical results find that firm effects have great impact on performance of the IT sectors of Taiwan and South Korea when estimated by either HLM or VCA. However, industry effects dominate firm effects on South Korea's IT sectors when the variance is estimated by HLM. From the perspective of conducting patents innovation, both of the specialized and diversified corporate strategies are matter to the development of these IT sectors, and South Korea's IT firms are more technologically diversified than those firms in Taiwan.     

Determinants of Successful IT-Enabled Business Innovation： A Case Study from the Perspective of Institutional Entrepreneurship Theory

As the role of information technology （IT） in business innovation becomes increasingly important, an increasing number of organizations have started to consider how to promote IT-enabled business innovation. Although extant studies have identified organization, environment, and innovation＇s characteristics as substantial determinants of IT innovation, they do not emphasize the accompanying innovation in processes, products or services, which distinguish IT-enabled business innovation from general IT innovation. Therefore, the reason why few companies succeed in realizing IT-enabled business innovation remains obscure. Anchored on the institutional entrepreneurship theory, this paper examines determinants of the success of IT-enabled business innovation in a fast-growing company using the case study approach. Our findings indicate that IT-business coordination competency, degree of institutionalization, participation of business managers, top management team＇s （TMT） attitude towards the innovation, and the innovation＇s relative strength, have significant impacts on the success of IT-enabled business innovation. Our findings also contribute to IT innovation research by identifying special determinants of IT-enabled business innovation and redirecting research ranging from innovation in IT itself to IT-enabled innovation in business processes, products or services.     

The relationship between CIO’s presence in the top management team and IT’s contribution to corporate innovation: An empirical study

This study investigates the impact of CIO’s presence in an organization’s top management team (TMT) on the contribution of information technology (IT) to corporate innovation. A new theoretical model is proposed based on the literature review. Through a survey of 120 CIOs of Chinese companies, we examine a series of hypotheses developed based on this model. Our findings reveal significant influences of CIO’s presence in the TMT on IT’s contribution to corporate innovations. The findings also suggest that such impacts are mediated by TMT’s IT knowledge. Furthermore, we find the significant moderating role of TMT’s risk appetite, i.e., when the executives are more willing to take risks, the relationship between CIO’s participation in TMT and the importance of IT to innovation is more significant. Theoretical contributions and practical implications of these findings are also discussed.     

The Effect of Environmental Corporate Social Responsibility on Environmental Performance and Business Competitiveness: The Mediation of Green Information Technology Capital

With the emergence of environmental sustainability and green business management, increasing demands have been made on businesses in the areas of environmental corporate social responsibility (ECSR). Furthermore, the influence of ECSR on green capital investment, environmental performance, and business competitiveness has also been the subject of attention from enterprises. However, in previous studies, the mediating role of green information technology (IT) capital in the relationship between ECSR, environmental performance, and business competitiveness, has not been investigated by researchers. In order to bridge this gap in the ECSR literature, this study aims to examine the influence of ECSR on green IT capital, and the consequent effect of green IT capital on environmental performance and business competitiveness. Data were collected from 358 companies from the top 1000 manufacturers in Taiwan. The results confirmed that ECSR has significant positive effects on green IT human capital, green IT structural capital, and green IT relational capital. Green IT structural capital and green IT relational capital have positive effects on environmental performance and business competitiveness, and environmental performance has a positive effect on business competitiveness. In addition, green IT structural capital and green IT relational capital have partial mediating effects on ECSR, environmental performance, and business competitiveness. The implications and suggestions for future research are discussed.     

Strategic Responses to Advances in Seismic Technology in the Petroleum Industry

The world petroleum industry has been revolutionized by a change in exploration technology from two‐dimensional (2D) to three‐dimensional (3D) seismic mapping. One of the main effects of the newer technology has been to decrease the cost of finding oil, particularly in offshore fields. We examine the impact of the new technology on the exploration activities of the major international petroleum companies and find that they have aggressively increased petroleum exploration expenditures. As a result, we suggest that the companies have achieved a prisoner's dilemma outcome, where they are collectively worse off in terms of profits, providing a possible explanation for the recent wave of large‐scale mergers in the industry.     

Price Discrimination and the Cruise Line Industry: Implications for Market Definition,Competition, and Consumer Welfare

This article extends the price discrimination literature and applies it to market definition and competitive effects analysis in recent mergers in the cruise line industry. In that industry, short run output is fixed. If firms want to increase price and restrict output to price‐insensitive customers, they have to increase the output and lower price to the price‐sensitive customers. We show that with fixed output (1) it is in firms’ interest to engage in price discrimination, (2) firms have increased ability to engage profitably in price discrimination as the intensity of competition decreases, and (3) the average price of price‐sensitive and ‐insensitive consumers increase with reduced competition. Unlike the economists at the Federal Trade Commission, our analysis suggests that cruise lines engage in third‐degree price discrimination. Moreover, the cruise industry could be a separate market and a reduction in the number of competitors might raise average prices.     

The Influence of IT Management Sophistication and IT Support on IT Success in Small and Medium‐Sized Enterprises

This study examined three factors that influence information technology (IT) success in small and medium‐sized enterprises (SMEs): internal IT support, external IT support, and IT management. Using survey data gathered from 289 small and medium‐sized Chartered Accounting firms in New Zealand, the results suggest that IT management in SMEs is best understood as a multidimensional concept consisting of practices related to: IT planning, IT organizing, IT controlling, and IT leading. This view clarifies and improves our understanding of the nature and character of IT management in SMEs. The results show that some SMEs are significantly more sophisticated than others in terms of their IT management practices. Both IT planning and IT leading were found to influence IT success.     

基于IT能力的企业信息化非技术影响因素研究

企业要想从信息技术应用中获得利润,必须投资于培育整体的信息技术能力,而并非孤立的IT系统。信息技术能力不仅依赖于技术因素,还依赖于非技术因素,单一非技术因素的忽视就能直接削弱企业信息技术能力。很多企业在信息化中对非技术因素缺乏足够的认识和管理,形成了非技术因素管理缺口,从而造成信息化项目成功率不高、效益不高。因此,针对我国企业信息化过程中的非技术因素问题,探索性地提出了构建基于IT能力的非技术因素分析框架,并对高层领导支持、组织变革与变革管理、企业的文化管理三方面的非技术因素以及之间作用机制进行重点分析。对推进我国企业信息化进程和整体信息技术能力的提升具有重要的现实意义。     

A curriculum model for IT infrastructure management in undergraduate business schools

As information technology infrastructure becomes strategic to organizations, the author examines business-school programs that educate future infrastructure analysts. Information systems (IS) 2010 and information technology (IT) 2008 curriculum models are used to survey courses required by telecommunications and IT infrastructure programs in business schools. Of 525 Association to Advance Collegiate Schools of Business–accredited schools, 259 have IS/IT programs and 18 have telecommunications and infrastructure-related programs. IT Infrastructure, Networking-Advanced, and IT Security are the top three infrastructure-related courses. Programs also require courses including IS Project Management; Social and Professional Issues; and IS Strategy, Management and Acquisition. Data collected are used to develop a new curriculum model of IT infrastructure management program that can be offered by business schools.     

A meta‐analysis of the UTAUT model: Eleven years later

The unified theory of acceptance and use of technology (UTAUT) has been widely used to investigate factors influencing the adoption and use of information systems and technologies (IS/IT). However, studies using UTAUT are not conclusive in terms of statistical significance, direction, and magnitude. Through a meta‐analysis of empirical studies on UTAUT from 2003 to 2013, we determine how parsimonious, accurate, and robust UTAUT is at predicting acceptance and use of technology. A meta‐analysis of 74 publications reveals that performance expectancy, effort expectancy, and social influence explain IS/IT adoption, while behavioural intention is the most often measured dependent variable operationalized as a proxy for system use, supporting the strength of UTAUT as an explanatory model of IS/IT acceptance and use.

A closer look at the productivity advantage of foreign affiliates

In analyzing firm productivity in Belgium, this article shows empirically that both scale and efficiency contribute positively to the typical productivity advantage of foreign affiliates. Stochastic production frontier estimation using the translog functional form indicates that foreign subsidiaries exploit economies of scale more fully and benefit from better (transferred) technological capabilities than Belgian national firms (i.e., Belgian owned firms without subsidiaries abroad). Belgian multinational enterprises (MNEs), i.e., Belgian owned firms with at least one subsidiary abroad, resemble foreign‐based MNEs in possessing specific technological advantages. While the increasing globalization has facilitated the realization of scale effects across borders, this article shows that the development of technological capabilities/advantages is still a prerequisite for MNEs to compete successfully abroad.     

The Role of Top Management Participation and IT Capability in Developing SMEs’ Competitive Process Capabilities

This research explores how top management participation and three types of IT capability enable SMEs' competitive process alignment and flexibility capabilities. Our research hypotheses are tested using data from 310 Australian SMEs. Results show that top management participation and external IT linkage capability positively affect both process alignment and process flexibility. While IT infrastructure capability and IT business spanning capability positively affect process alignment, they are not significantly related to process flexibility. In addition, both process alignment and process flexibility capabilities have significant positive effects on SME performance. Contributions and implications of this study are discussed.     

A Cointegration Analysis of Car Advertising and Sales Data in the Presence of Structural Change

This paper examines whether there is a long‐run stable equilibrium relationship between advertising and sales across the market segments of the UK car industry over the period 1971–2001. In order to achieve this goal, we allow for structural breaks in the series using cointegration techniques. The results show the existence of long‐run equilibrium relationships in all six market segments, although in four of them the relationship is not stable. In general, one structural change is detected in the late 1970s and another in the early 1990s, coinciding with two economic recessions. When we do not account for structural changes, the estimated long‐run elasticities of advertising on sales are seen to be substantially downwardly biased. Finally, a noticeable increase is observed in long‐run elasticities in most car market segments during the nineties with respect to previous decades.     

How should information technology be covered in the accounting program?

Professional accounting associations, business schools, and accounting professors are increasingly faced with an important question: Which information technology (IT) competencies should be developed in accounting programs to train skilled professional accountants? Key references in accounting education show that advanced‐level training in IT is very important for accountants’ careers. Through content analysis, I investigate how Canadian CPAs are trained in IT. Results indicate that, postmerger, IT has lost ground in the CPA program. This could be mainly due to: (a) a larger coverage in finance, strategy, and governance topics; (b) challenges to promote and teach IT in terms of course development; and (c) a lack of recognition of and incentives for academic work on IT. Compared to some key players in accounting education, it appears that Canada has taken a different route with regard to the required IT competencies. Copyright © 2016 ASAC.
