This paper addresses the operations challenges of effectively managing professional services on a global scale. The specific context for the study is professional engineering services and particularly those that are delivered globally – global engineering services (GES). Estimates suggest that the market for GES was around US$930 billion in 2012, rising to US$1.4 trillion by 2020 (ISG, 2013). Yet this influential sector receives scant attention in the operations management literature. The paper draws on six case studies to explore the operations management challenges of delivering GES. In doing so the paper introduces the concept of network capabilities for GES, highlighting the centrality that: (i) network resources – accessing and deploying dispersed resources, (ii) network coordination – coordinating and integrating network activities, and (iii) network learning – collective learning and knowledge management, all play in enabling the successful operational management of GES.  相似文献

This paper empirically investigates the main drivers of airline network concentration in an air transport market subject to rapid growth. We consider the Brazilian air transport industry of the 2000s, in which network concentration rapidly increased and was followed by a period of massive flight delays and cancelations, which resulted in the “big blackout” of 2006–2007. We develop an econometric model of network concentration, accounting for demand, cost and competition variables that may affect the propensity of carriers to concentrate flights and passenger connections on a few airports of a network. The main focus of the paper is on the relation between networks leading to the problems of the blackout episode. We investigate the dynamic pattern of the evolution of concentration before and after the abnormal period of operations and find that concentration began to rise at least six quarters before, and persisted at a high level until two quarters after the blackout – and then plunged steeply toward the end of the decade. We believe that our analysis contributes to an improved understanding of the behavior of air transport systems subject to network concentration and congestion. With respect to methodology, we suggest and employ the use of alternative measures of network concentration to check the robustness and validity of our results.  相似文献

Although productivity spillovers have long been recognized to be a major benefit of foreign direct investment (FDI), such spillovers have not yet been systematically studied in the context of the hotel industry. This paper investigates hotel-related FDI spillover effects as well as moderating factors (geographic region, star rating classification, ownership type and foreign capital origin) in China. Evidence from province-level panel data reveals the existence and significance of intra-industry spillovers from foreign to domestic hotels in China, although the nature and magnitude vary based on different moderating factors. Domestic hotels in eastern and western China and those with alliance and limited liability ownership structures benefit significantly from productivity spillovers. Foreign-invested three-star hotels transfer a significant amount of positive productivity, whereas domestic three- and five-star hotels benefit the most from productivity spillovers. Moreover, foreign-invested hotels from Hong Kong, Macau, and Taiwan (HMT) and non-HMT countries generate positive spillovers of similar magnitudes.  相似文献

While takeover targets earn significant abnormal returns, studies tend to find no abnormal returns from investing in predicted takeover targets. In this study, we show that the difficulty of correctly identifying targets ex ante does not fully explain the below‐expected returns to target portfolios. Target prediction models’ inability to optimally time impending takeovers, by taking account of pre‐bid target underperformance and the anticipation of potential targets by other market participants, diminishes but does not eliminate the potential profitability of investing in predicted targets. Importantly, we find that target portfolios are predisposed to underperform, as targets and distressed firms share common firm characteristics, resulting in the misclassification of a disproportionately high number of distressed firms as potential targets. We show that this problem can be mitigated, and significant risk‐adjusted returns can be earned, by screening firms in target portfolios for size, leverage and liquidity.  相似文献

This article picks up a discussion in international business accounting about the appropriate definition and use of conservatism (or prudence) and calls for a similar discussion in public sector accounting. If financial reports present an overly optimistic situation, politicians might use them to justify spending public money that is not there, risking the sustainability of services and ‘borrowing’ from future generations.  相似文献

We study HRM practice implementation in subsidiaries of multinational corporations (MNCs) and diverge from extant research by focusing on alignment, which we conceptualize as the degree to which subsidiary implementation of HRM practices corresponds with the subsidiary-specific transfer intentions of corporate headquarters. In explaining alignment we examine different aspects of the headquarters–subsidiary relationship, namely, the extent of formal control, interpersonal relationships and subsidiary strategic HRM capabilities. Based on a sample of 105 subsidiaries from 12 Nordic MNCs, the results highlight the importance of expatriates, trust and the strategic HRM capabilities of the subsidiary HR function. We conduct post hoc analyses to shed further light on (i) the relationship between our independent variables and the two separate components of alignment – corporate intentions and subsidiary implementation, and (ii) two different types of misalignment – excessive and insufficient.  相似文献

We tested the applicability of the push-pull-mooring (PPM) migration theory to travelers' airline selection in order to clarify their switching behavior. Based on the extensive review of the literature and open-ended survey, we identified the constituents of four push, three pull, and four mooring factors. A field survey was conducted at an international airport in South Korea, and a total of 529 complete responses were used for data analysis. Our results showed that the PPM model comprising the second-order factor structure provided an acceptable representation of the observed variables in a comparison with the first-order construct model. Results of the structural analysis also indicated that all PPM categories directly affected switching intention. In addition, mooring dimension had a significant moderating effect on the relationship between pull category and switching intention. However, no moderating effect of mooring factor on the relationship between push factor and switching intention was found.  相似文献

Although research on industry clusters has made many valuable contributions, a dearth of empirical evidence and theoretical reflection about the characteristics of Base of the Pyramid (BOP) clusters has persisted. Consequently, the literature still lacks a framework that incorporates the context, challenges, and dynamics encountered in such clusters. Drawing from clusters, capability accumulation, and innovation literatures, we develop a theoretical framework that provides a more fine-grained understanding of the dynamics encountered in BOP clusters, the role of support organizations, the importance of capabilities accumulation in firms, and the challenges associated with technology development and diffusion within such settings. We use case study research method conducted in a traditional granite-mining cluster in Brazil, based on 154 interviews with key informants between 1999 and 2011. Our findings suggest that BOP clusters present different dynamics when compared to clusters elsewhere, because of the existence of idiosyncrasies such as additional barriers to technology diffusion, especially when coupled with a lack of coordination and misaligned policy approaches. We contribute to the literature by arguing that the process of technology diffusion in BOP clusters is hindered by these barriers, and that technology development without wide diffusion within BOP clusters can become a source of social exclusion and wealth concentration. Moreover, in large emerging economies, global pipelines are not necessarily the only path for BOP clusters to achieve competitive advantage and sustainable growth, as suggested in the clusters literature.  相似文献

This study investigates the relationship between managerial entrenchment and how firms meet or beat earnings forecasts. It further examines whether this relationship changes before and after the Sarbanes–Oxley Act (SOX). We find that, in the pre-SOX era, entrenched managers meet or exceed analyst forecasts more often than their unentrenched counterparts when analysts’ initial forecasts are high. This is mainly due to the drop in analysts’ consensus rather than earnings management. These results nearly disappear in the post-SOX era.  相似文献
