Inequality and network structure

We explore the manner in which the structure of a social network constrains the level of inequality that can be sustained among its members, based on the following considerations: (i) any distribution of value must be stable with respect to coalitional deviations, and (ii) the network structure itself determines the coalitions that may form. We show that if players can jointly deviate only if they form a clique in the network, then the degree of inequality that can be sustained depends on the cardinality of the maximum independent set. For bipartite networks, the size of the maximum independent set fully characterizes the degree of inequality that can be sustained. This result extends partially to general networks and to the case in which a group of players can deviate jointly if they are all sufficiently close to each other in the network.     

Structural and contextual correlates of charged behavior in product development teams

Firms increasingly use cross‐functional teams to develop new products, yet we know little about the processes that make teams excel. Although studies have focused on within‐team processes like cooperation between and integration of individuals from various functional areas, some emerging literature suggests that the processes that make teams excel are richer and more complex than cooperation and integration. In order to capture the processes that lead to excellent market performance of new products, we introduce the concept of charged team behavior, the extent to which cross‐functional product development teams are enthusiastically and jointly driven to develop superior new products. Charged team behavior captures not only the drive, commitment, and joy of team members, but also their collaborative behaviors to achieve an exceptional outcome. We propose and test a series of hypotheses concerning how charged behavior affects new product market performance and how charged behavior is, in turn, influenced by both team structural characteristics (physical proximity, team longevity, and outcome interdependence) and contextual factors (senior management encouragement to take risk, quality orientation, exposure to customer input, extent of competition, and interdepartmental connectedness). It is particularly important to examine the antecedents of charged behavior because there are concerns that some of the team‐related factors generally considered to be useful for teams may not necessarily lead to charged teams. Data from new consumer product development teams is analyzed though structural equation modeling for hypothesis testing. We find evidence that highly charged teams are more likely to develop successful new products. Results also indicate that outcome interdependence, exposure to customer input, extent of competition, and interdepartmental connectedness are positively related to charged behavior. Physical proximity, team longevity, encouragement to take risk, and quality orientation do not improve teams' charged behavior. Data suggests that charged team behavior: 1) fully mediates the effects of outcome interdependence and interdepartmental connectedness on performance, 2) partially mediates the influence of exposure to customer input and the extent of competition on performance, and 3) does not mediate the effects of quality orientation and physical proximity on performance. Our study highlights the importance of creating highly charged product development teams in order to achieve exceptional performance. Further, our results indicate that some of the factors suggested by traditional social psychology research for enhancing team effectiveness (e.g., physical proximity and team longevity) may not necessarily create charged teams. Instead, charged teams need a special arrangement, in which members are accountable to the team and where their evaluations and rewards are also linked to the performance of the team. In addition, although a strong emphasis on quality is considered to be beneficial for new products, as our results indicate, such emphasis cannot create a charged atmosphere. Moreover, our research suggests that if the organization structure does not permit frequent contact between individuals across functional boundaries, the creation of a strongly charged team and development of a successful new product will be hindered.     

The Medicare Electronic Health Records (EHR) Incentive Program: First-Year Adoption Response from Inpatient Hospitals

This study investigates electronic health records (EHR) adoption among inpatient hospitals in response to the first operational year of the Medicare EHR Incentive Program. Profile analysis of public attestation datasets finds both system adoption rates and implemented functionalities to have been significantly influenced by the incentive program’s attributes. Key dates and periods in the program’s well-publicized timeline were usually accompanied by spikes in the number of attested systems and/or dips in advanced functionalities. The implication is that hospitals have responded to the program by swiftly implementing EHR systems with capabilities just sufficient to meet program requirements, in order to be able to promptly file attestations and thus claim their incentive payments. The program therefore appears to have yielded mixed results. While it seems to have induced more hospitals to acquire EHR systems, the implemented systems generally possess minimal functionalities, suggesting that adopters have leveraged the program’s rules in order to maximize their own short-term gains.     

Optimal Financing of a Corporation Subject To Random Returns

We consider the problem of finding an optimal financing mix of retained earnings and external equity for maximizing the value of a corporation in a stochastic environment. We formulate the problem as a singular stochastic control for a diffusion process. We show that the value function satisfies a free-boundary problem. We characterize the value function and show that the optimal policy can be characterized in terms of two threshold parameters. With asset level below the lower threshold, optimal policy is to finance the firm's growth by retaining all earnings and raising the required external equity financing. With asset level above the higher threshold, optimal policy is to pay all retained earnings as dividends and to bring in no new equity. Between the two thresholds, the optimal policy is to retain all earnings but not raise any external equity. We obtain an explicit solution for the value function when there is no brokerage commission in floating external equity. We provide economic interpretations of the results obtained in the paper.     

Reappraising liabilities of foreignness within an integrated perspective of the costs and benefits of doing business abroad

Several international business scholars have elaborated upon Hymer's [Hymer, S. H. (1960). The international operations of national firms: A study of direct investment. Unpublished Ph.D. dissertation, MIT, Cambridge, MA] costs of doing business abroad through the liability of foreignness notion. While this research has made important contributions, there is need for more conceptual refinement and synthesis due to the vastly increased scale and scope of MNE operations in recent years. Consequently, this study attempts to more precisely delineate the liabilities of foreignness component of costs of doing business abroad from other costs/liabilities that arise from the increasing complexity of global business. Further, we synthesize both the costs and benefits of cross-border operations that accrue to the foreign subsidiary into an integrated conceptual framework, and advance 11 theoretical propositions on how those impact its competitive dynamics. We illustrate these notions through a longitudinal case study on the operations of Ford Motor Company in India over the past 80 years.     

THEORIES OF THE FIRM: IMPLICATIONS FOR STRATEGY RESEARCH*

Theories of the firm provide a perspective for thinking about organizational objectives and a framework for analysing important research problems. Here, we demonstrate the usefulness of several economic theories of the firm for guiding strategy research. We evaluate the relevance of each theory with regard to how the underlying conceptualization of the firm permits us to investigate issues of substantive interest to strategy researchers, and how compatible the assumptions contained within the theory are with the traditional strategy framework. We also examine the relevance of the theories from the viewpoint of philosophical methodology. We argue that, because of the integrative nature of strategy research, it is imperative for researchers to adopt multiple frameworks represented by different theories for the advancement of the field.     

Operational modes for multinational corporations in post-apartheid South Africa: A proposal for a code of affirmative action in the marketplace

The economic and socio-political impact of multinational corporations (MNCs) on third world countries has been the subject of intense debate and controversy leading to charges of exploitation and colonization on the one hand, and demands for codes of conduct on the other. This article examines the working of one of the most comprehensive of such codes under the most reprehensible political conditions, i.e., the operations of U.S.—based multinational corporations in South Africa under the acgis of the Sullivan Principles. It is argued that despite the best intentions, and considerable social goodwill, the Sullivan Principles were seriously flawed both as to goals and as to means of achieving them. Finally, it suggests a new approach to developing standards of MNC behavior in third world countries which emphasizes those areas of activities that are directly under the control of MNCs, and offers targets of achievement to which MNCs can and should be held accountable.The paper is a revised and expanded version of a keynote speech delivered by the author at the First Biannual Conference on Advances in Management, Orlando, Florida March 25–28, 1992.S. Prakash Sethi is Professor and Associate Director, Center for Management, Baruch College, The City University of New York. He is also the Economic Policy Advisor to the National African Federated Chamber of Commerce and Industry (NAFCOC), which is the largest and the oldest organization of Black business and industry people in South Africa.     

Relating strategy and structure to flexible automation: A test of fit and performance implications

This study analyzed various strategy and structure choices to determine their fit relationship with flexible automation (FA). ¹Using the moderator hypothesis, we proposed that the more strategy and structure choices complemented FA's competences, the higher would be the performance impact of FA. Data from 87 FA users indicate that quality and flexibility strategies, described as complementary to FA's strengths, interact positively with FA. Low cost strategy, described as conflicting with FA, interacts negatively. Organic structure, viewed as complementary to FA, has only main effects whereas a mechanistic structure interacts negatively. At the manufacturing level, skill diversity and team approaches, considered as complementary to FA, interact positively. While a subgroup analysis of high-low performers lends additional support to these relationships, analysis of industry subgroups indicates that some relationships are industry specific. We discuss the implications of these findings for research and practice.     

Racial Inequality and Segregation Measures: Some Evidence from the 2000 Census

How much of the observed segregation between black and white Americans can be attributed to income disparities between the two groups? We adopt an approach to the decomposition of segregation measures that combines the method of indirect standardization with the idea that some degree of segregation is the outcome of purely random processes. Using the dissimilarity index as a measure of segregation and data on race and income from US metropolitan areas for 2000, we find that the role played by racial income inequality in accounting for segregation is modest but varies significantly across cities.
