An empirical investigation of intraurban wage gradients

Intraurban wage gradients have received little attention in the urban literature but have been shown theoretically to be important indicators of the spatial characteristics of urban economic activity. This study examines the spatial distribution of wages of five groups of municipal public employees in the Chicago SMSA. Negative wage gradients, significant at the 0.05 level, are found for four of the five labor groups. Results show that monthly wages decrease on average as much as $24 per additional mile from the city center.     

An empirical investigation of scheduling performance criteria

Planning and scheduling significantly influence organizational performance, but literature that pays attention to how organizations could or should organize and assess their planning processes is limited. We extend planning and scheduling theory with a categorization of scheduling performance criteria, based on a three-stage survey research design. Particularly, the results show that, next to schedule quality, the planning process factors timeliness, flexibility, communication, and negotiation are important performance criteria, and especially so in organizations that are faced with high levels of uncertainty. The results suggest that organizational and behavioral aspects of planning and scheduling cannot be mitigated with advanced models and software that solely focus on good schedules. Rather, high quality schedules and high quality scheduling processes need to be facilitated simultaneously to attain high planning and scheduling performance.     

An empirical investigation into supply chain vulnerability

A growing number of academicians and practitioners have put supply chain risks on their agendas, particularly triggered by a recent series of catastrophic events that have disrupted economies and supply chains around the globe. Given the increasing awareness of this important topic, the purpose of this research was to study supply chain risks in more detail and to investigate the relationship between supply chain vulnerability and supply chain risk. Responses from 760 executives from firms operating in Germany reveal that supply chain characteristics such as a firm's dependence on certain customers and suppliers, the degree of single sourcing, or reliance on global supply sources are relevant for a firm's exposure to supply chain risk. Overall, this research represents the first large-scale investigation of this important relationship and provides a finer understanding of the antecedents of supply chain vulnerability.

我国新股首日回报率的实证分析

新股首日超额回报是世界范围的一种普遍现象,而在我国尤为突出,国内外对此给出了各种解释,但至今尚未形成一致性认识,文章选取1996年1月至2004年12月在我国上海证券交易所上市的616只A股为样本,进行了横截面的分析后发现:信息不对称并非我国新股折价的主要原因,我国新股折价是由二级市场投机引起。     

Channels of R&D spillovers: An empirical investigation of Swiss firms

Research and development (R&D) spillovers are, potentially, a major source of endogenous growth in various recent ‘new growth theory’ models. According to these models, firms engage in R&D in order to seek rents. Public aspects of this R&D then spill over to other firms, thereby creating increasing returns relating to scale and long-term growth. The actual mechanisms by which spillovers occur has, however, not been systematically studied. In order to provide empirical facts on this issue the paper investigates the effectiveness of various channels of R&D spillovers. The analysis is based on a survey conducted among 358 Swiss R&D executives representing 127 different lines of business, mainly in the manufacturing sector. The results can be summarized as follows. First, undertaking independent R&D was perceived by the R&D executives questioned as the most effective channel of R&D spillovers at the intra-industry level. This was followed by reverse engineering for product innovations and the utilization of publications and information from technical meetings for process innovations. Second, learning methods that rely on interpersonal communication were judged as moderately effective in the following order of importance: (i) publications and technical meetings; (ii) conversations with employees from innovating firms; and (iii) hiring away employees from innovating firms. The last method, especially, is not valued as effective in the Swiss context. Third, learning methods related to the patent system—licensing technology and patent disclosures in the patent office—were seen as moderately effective or not effective at all. Fourth, the effectiveness of the various channels of R&D spillovers varies from one industry to another. Fifth, the various channels of R&D spillovers can be reduced to subgroups, so that patterns of learning of competitive technology can be established.     

Investment behavior under Knightian uncertainty – An evolutionary approach

The ‘as if ’ view of economic rationality defends the profit maximization hypothesis by pointing out that only those firms who act as if they maximize profits can survive in the long run. Recently, the problem of arriving at a logically consistent definition of rational behavior in games has shown that one must sometimes study explicitly the evolutionary processes that form the basis of this view. The purpose of this paper is to investigate the usefulness of genetic programming as a tool for generating hypotheses about rational behavior in situations where explicit maximization is not well defined. We use an investment decision problem with Knightian uncertainty as a borderline test case, and show that when the artificial agents receive the same information about the unknown probability distributions, they develop behavior rules as if they were expected utility maximizers with Bayesian learning rules.     

An empirical investigation of different strategies for material requirements planning

Master production scheduling, component lot sizing, and capacity requirements planning represent three important modules of material requirements planning (MRP) systems. Coordinating these three modules has been largely dependent on managerial judgment and experience. In this research, five different strategies for integrating these modules are empirically investigated. These strategies differ mainly in the extent to which the modules are coordinated. The impact of the shop, product, component and cost characteristics is measured by varying ten experimental factors. The research findings so obtained provide several guidelines on the effectiveness of each strategy in different environmental settings.     

Economic rents and mutual fund performance: An empirical investigation

We investigate the monthly returns of 377 open-end mutual funds during the September 1981–1994 period to learn whether economic rents can be garnered through the judicious selection of the advertising and sales method in the mutual fund industry. Specifically, we seek to learn whether direct sales or mass marketing produces economic rents under the assumption that those rents would be passed on to consumers to build a “high quality” image to differentiate the product line. Results suggest that no-load funds produce superior net returns except in the aggressive growth category.     

Benchmarking institutional variety in the eurozone: An empirical investigation

The European debt crisis has shown that the future of the European Union (EU) depends on the willingness of each member country to implement responsible policies, avoid moral hazard and uncooperative attitudes, and ensure stability and soundness. However, the European institutional variety means that each member country reacts differently to shocks and policies, follows a different path of recovery, and adapts to common institutions, including the common currency, in different ways. Helping countries to converge toward a situation that guarantees well-being, stability, and development at the national and community level is the goal of the European benchmark. This benchmark is a framework inspired by European treaties that, through the distance-to-frontier score methodology, aims to measure member countries’ performance and identify inefficiencies and negative externalities within the economic, social, and political institutions of each member country. The paper presents an empirical investigation of the European benchmark. Based on the results obtained, all countries can improve their performance, and none of them can be considered a model for the others. However, the Mediterranean and post-communist countries have more challenges to face and therefore need to make greater efforts.     

Profit distribution management by Islamic banks: An empirical investigation

The objective of this paper is to ascertain whether Islamic banks do in fact manage profit distributions and if so, what factors are associated with the extent of profit distribution management. The results suggest that most Islamic banks manage profit distributions, with the extent of profit distribution directly related to religiosity, financial development, asset composition, and existence of discretionary reserves, while it is inversely related to market familiarity with Islamic banking, market concentration, depositor funding reliance and the age of the Islamic bank.     

“100% EDI-connected suppliers” projects: An empirical investigation of success factors

Electronic Data Interchange (EDI) is becoming increasingly important, and new organizational forms based on EDI suppliers’ capabilities are emerging. Therefore, taking advantage of recent technological changes, especially the development of Web-based EDI systems, many big industrial buyers are seeking to get all their suppliers EDI-connected. Based on previous research on EDI adoption, we conducted a survey to study the opportunities of success of such a “100% EDI-connected suppliers” policy using data from the vehicle industry. Findings from our survey helped us to understand suppliers’ responses to such a policy and to provide recommendations to industrial buyers who are seeking to succeed in a “100% EDI-connected suppliers” project. This includes employing tailored communication strategies and selecting appropriate incentives that take into account different levels of suppliers’ EDI-capabilities and suppliers’ dependence.     

Information systems project manager soft competencies: A project‐phase investigation

This article investigates the soft competencies by project phase that information systems (IS) project managers require for project success. The authors conducted 33 qualitative interviews to collect data from a sample of 22 IS project managers and business leaders located in Calgary, Alberta, Canada. The authors identified the key competencies for each of the IS project phases (initiation, planning, implementation, and closeout). The competencies were sorted into competency categories: personal attributes (e.g., eye for details), communication (e.g., effective questioning), leadership (e.g., create an effective project environment), negotiations (e.g., consensus building), professionalism (e.g., lifelong learning), social skills (e.g., charisma), and project management competencies (e.g., manage expectations). Each of the most important competencies is discussed and interconnections among competencies identified. How this research can be used by the practitioner and academic communities and the broader implications of this research are examined.     

An empirical investigation of the effectiveness of an integrated service recovery system

Although service recovery has become an increasingly-studied topic in the operations management literature, robust theories and accompanying empirical studies have only begun to emerge. For example, while many authors have identified and measured the specific activities that are perceived by consumers as effective ways to recover from failure, much less attention has been directed at the systematic structuring of recovery efforts to consistently ensure customer satisfaction and achieve improved, long-term organizational outcomes. Building on recent research that identified the principal constructs of service recovery, this study seeks to explore the relative effectiveness of an integrated service recovery system. Data from 158 service organizations are used to explore the relationship between the system and its associated recovery outcomes. Results indicate that a complete recovery system defined by seven distinct dimensions (formalization, decentralization, comprehensiveness, accessibility, influence, human intensity, and system intensity,) significantly impacts internal capability improvements as well as externally-perceived outcomes (i.e., speed, employee empathy, and recovery effectiveness) while both of these outcomes have a significant impact on customer satisfaction and market performance attributed to service recovery     

The effects of Six Sigma on corporate performance: An empirical investigation

The purpose of this study is to investigate the impact of adopting Six Sigma on corporate performance. Although there is a fairly large and growing body of anecdotal evidence associated with the benefits of implementing Six Sigma, there is very little systematic and rigorous research investigating these benefits. This research extends previous research in several important ways including utilizing a sample of 84 Six Sigma firms that represent a wide variety of industries and firm characteristics, utilizing rigorously constructed control groups to ensure the validity of our comparisons and conclusions, and investigating the impact of adopting Six Sigma on corporate performance over a ten year period. To carry out this investigation, the event study methodology is employed. The ten year period consists of three years prior to Six Sigma implementation, the event year corresponding to the year Six Sigma is adopted, and six years post Six Sigma implementation. To assess the impact of adopting Six Sigma on corporate performance we utilize commonly used measures including Operating Income/Total Assets (OI/A), Operating Income/Sales (OI/S), Operating Income/Number of Employees (OI/E), Sales/Assets (S/A), and Sales/Number of Employees (S/E). The sample Six Sigma firms are compared to different benchmarks including the overall industry performance and to the performance of carefully selected portfolios of control firms. The results of the study indicate that adopting Six Sigma positively impacts organizational performance primarily through the efficiency with which employees are deployed. More specifically, enhanced employee productivity results were observed in both static analyses that assessed the performance of the sample Six Sigma firms relative to their control groups at discrete points in time and dynamic analyses of the Six Sigma firms’ rate of improvement relative to the rate of improvement of their control groups. Benefits in terms of improved asset efficiency were not observed. Finally, there was no evidence that Six Sigma negatively impacts corporate performance.     

The effects of supplier-to-buyer identification on operational performance—An empirical investigation of inter-organizational identification in automotive relationships

Over the past decade conceptual and empirical research in operations management has embraced the idea that collaborative supplier-buyer relationships are a source of competitive advantage for manufacturing firms. Anecdotal evidence from the Japanese and U.S. automotive industry and emerging research suggests that inter-organizational identification of suppliers with their buyers, termed supplier-to-buyer identification, is an unexplored factor of relational advantage. This study presents a model and empirical test that supplier-to-buyer identification fosters superior operational performance by enhancing trust, supplier relation-specific investments, and information exchange. Through a survey of 346 automotive supplier-buyer relationships, the findings show that supplier-to-buyer identification directly impacts supplier relationship-specific investments and information exchange, although most of the latter effect is mediated by trust. The findings also indicate that supplier relation-specific investments and information exchange play different but complementary roles in influencing operational performance. The results suggest new directions for supplier-buyer relationship research in operations management and important managerial implications.     

The concepts of power in international business negotiations: An empirical investigation

This article examines the bases of social power, namely individual information power, expert power, legitimate power, and referent power on successful international business negotiations (IBNs). The author conducted an online survey among international business executives working in the UK for multinational corporation subsidiaries who were asked to report on the success of their most recent negotiating experience in terms of cooperative (integrative) and competitive (distributive) outcomes. Information power, expert power, and referent power were supported by these results in terms of significance. Unexpectedly, however, information power was positively correlated with integrative or cooperative outcomes and processes. The correlation related to legitimate power was negative but not statistically significant so this hypothesis was not supported. Our results not only contribute to international negotiation theory, but also can assist in the selection and training of practitioners. The academic contribution of this study also relates to model exploration. It brings causal statistical objectivity to qualitatively developed concepts as an essential step in development of knowledge. These theoretical and managerial implications of the study are examined. Furthermore, directions for future research that build on the findings of the study are indicated.     

Credit in the euro area: An empirical investigation using aggregate data

This paper uses multivariate cointegration techniques to estimate a model of aggregate bank lending in the euro area. The model provides a quantitative benchmark for assessing conjunctural developments in loans to the area-wide private sector. Large and protracted deviations of realised loans from the paths implied by the model may reveal information about the emergence of financial imbalances as well as about the state of the economy, particularly about the strength of inflationary pressures. A specific application of the model shows that its error-correction term contains information on future changes in inflation over forecast horizons of relevance for monetary policy.     

An empirical investigation of going private decisions of U.S. firms

According to many managers, the Sarbanes-Oxley Act of 2002 caused the costs of being public to increase. Subsequently, following the Act, many firms went private rather than incur the costs. We investigate the differences in the financial characteristics of firms that went private between 1998 and 2003 and a control sample of firms which went public and did not go private Our results indicate that there are differences in the two groups, as well as differences in firms that went private prior to and following Sarbanes-Oxley. Taken together, our results are indicative of going private to avoid the higher costs of being public post Sarbanes-Oxley.     

Corporate environmental policy and abnormal stock price returns: An empirical investigation

This paper examines the correlation between the excess stock market returns and the adoption of an environmental protocol by companies. The underlying hypothesis that I test is whether evidence of the adoption of environmental policy, prosecution by an environmental agency or the routinized training of staff in environmental protocols, which proxies for the willingness of managers to invest for the long term, is associated with superior economic returns to shareholders. I find that both the adoption of an environmental policy and prosecution for breach of environment standards have significant explanatory power in an analysis of excess returns.
