Information Processing Hierarchies

This paper characterizes optimal stationary hierarchies based on an information processing model introduced by Radner. We show how the delay, size (number of processors), capacity (the size of each cohort processed), and throughput (frequency of cohort arrival) are related and determine a feasibility frontier in the space of these variables. The structure of efficient hierarchies implementing the points on the feasibility frontier is also specified. These structures are always nonregular; i.e., every agent has subordinates from several different levels. The nature of the long accepted maxim of decreasing returns to scale in management hierarchies is demonstrated. When the production function of the hierarchy is taken to be the number of information items it can process, we find that returns to size and delay are always decreasing in efficient hierarchies, but these variables are complementary in the design problem. Finally, we discuss how the underlying abilities of the processors affect the marginal returns to size and delay. Journal of Economic Literature Classification Numbers: L22, D83.     

The impact of CEO core self‐evaluation on the firm's entrepreneurial orientation

Although much has been attributed to a CEO's personality, one particularly intriguing, and as yet unexplored, investigation is its impact on the firm's entrepreneurial orientation. Additionally, despite calls from the upper‐echelon literature, CEO personality research has been hobbled by the absence of a unifying construct that captures core dimensions of personality, and by the difficulty in obtaining such intimate assessments from executives. Building on recent advances in personality research, in particular the identification and validation of the core self‐evaluation construct that captures the core facets of an executive's sense of self‐potency, we develop and test a model of the impact of CEO core self‐evaluation on entrepreneurial orientation. Then, consistent with upper echelons and personality theory, we specify the contingent role of environmental dynamism. Using multisource data from a sample of CEOs and their top management teams from 129 firms, including a time‐lagged assessment of the firm's entrepreneurial orientation, we find evidence to suggest that CEOs whose personalities reflect higher core self‐evaluations have a stronger positive influence on their firms' entrepreneurial orientation. In addition, we find that this influence is particularly strong in firms facing dynamic environments, but negligible in stable environments. Copyright © 2009 John Wiley & Sons, Ltd.     

Effects of Demographic Characteristics of Logistics Firms on Their Performance and Job Satisfaction of Their Employees

This study investigates the effects of demographic factors of the logistics firms＇ employees （gender, age, education level, experience level, and department） on their job satisfaction and the effects of demographic factors of the logistics firms （company type, capital nature, and company experience level） on their performance of logistics activities about information technologies, interior relationship, and transportation based on the scale developed by the same authors and the sample of 39 logistics firms selected randomly in the city of Mersin and Adana in Turkey. According to findings, none of the demographic factors of the employees does aft~ct their job satisfaction. In terms of the demographic factors of the logistics firms, their experience level in the field is found to be significant in their logistics activities about information technology. In general, as the firm＇s experience increases, they perform better on information technology.     

Computing Cournot equilibrium through maximization over prices

This paper presents a characterization of internal Cournot equilibrium based on first-order conditions corresponding to profit maximization over prices. This characterization may yield significant computational advantage as demand functions need not be inverted and simple first-order conditions are obtained.     

CEO tenure and organizational performance: an intervening model

While CEO job tenure is seen as influencing firm performance, the intervening mechanisms that govern this influence have remained largely unexplored. Given that individuals in the firm most closely influenced by the CEO are members of the top management team (TMT), we focus on the CEO‐TMT interface as one important intervening mechanism. Specifically, our tested model suggests that CEO tenure indirectly influences performance through its direct influences on TMT risk‐taking propensity and the firm's pursuit of entrepreneurial initiatives. Results from structural equation modeling are consistent with this model and support its associated hypotheses. In the discussion, we trace the implications of our study for research and practice.

Gender,generation and sustainable consumption: Exploring the behaviour of consumers from Izmir,Turkey

This study investigates the relationship between consumers’ sustainable consumption behaviour and both gender and generation‐related individual differences in a sample of Turkish consumers. A total of 393 participants from different generations and gender took part in the study. To measure sustainable consumption behaviour, we used four‐dimensional sustainable consumption behaviour scale. The results showed that generation is associated with unneeded consumption as a dimension of sustainable consumption behaviour. Consumers who are Baby Boomers found to have the highest level of unneeded consumption behaviour while Gen‐Zers have fewest. Additionally, data supported the association between gender and sustainable consumption behaviour. Women showed a higher level of sustainable consumption behaviour both in overall behaviour and tendency to reuse products. Taken together, the findings suggest that gender and generation of consumers can differentiate sustainable consumption behaviour. The implications of these findings, as well as the limitations and future directions, are also discussed.     

The Impact of Managerial Environmental Perceptions on Corporate Entrepreneurship: Towards Understanding Discretionary Slack's Pivotal Role

abstract    This study seeks to further delineate how a firm's competitive environment influences the firm's pursuit of entrepreneurial activities. To do so, we develop and test a parsimonious model that establishes the role of discretionary slack as a salient mediating mechanism through which managerial environmental perceptions influence corporate entrepreneurship. In addition, we examine two contingencies that further explain discretionary slack's impact on corporate entrepreneurship, including managements' market sensing capacity and use of outcome-based incentives. Using single- and multi-source survey data from 495 small- to medium-sized firms, we find support for our model and its associated hypotheses. Specifically, we find that discretionary slack is significantly influenced by managerial perceptions of environmental munificence and dynamism and, in turn, mediates the impact of these perceptions on corporate entrepreneurship. In addition, we find that discretionary slack's impact on corporate entrepreneurship is significantly enhanced by managements' market sensing capacity but, interestingly, not by outcome-based incentives.     

Decision Comprehensiveness and Corporate Entrepreneurship: The Moderating Role of Managerial Uncertainty Preferences and Environmental Dynamism

Although comprehensiveness is considered among the most salient and enduring strategic decision-making characteristics in organizations, its influence on firm behaviour has remained elusive. As a first step, our study builds and tests a model that specifies the influence of comprehensiveness on the firm's pursuit of corporate entrepreneurship. Our core argument is that while comprehensiveness helps decision-makers gain the knowledge needed to escape the ignorance and overcome doubt associated with this pursuit, this beneficial influence is conditional upon managerial uncertainty preferences, together with the level of dynamism in the external environment. Findings from a large sample study of CEOs from 349 SMEs provide general support for this argument and associated hypotheses.     

Export Subsidies and Exchange Rate Pass‐through

This paper investigates effects of exchange rate on optimal trade policies and market prices within a standard export subsidy model. Shifts in exchange rate change relative efficiencies of firms in different countries. We show that depreciation of own currency increases subsidy levels when marginal cost is constant. Import dependency weakens this relationship, decreasing sensitivity of subsidy levels to depreciation. In general, subsidies reduce exchange rate pass‐through. Additionally, perverse exchange rate pass‐through effect arises with sufficiently intensive subsidies.
