Shifting Imperatives: An Integrative View of Resource Scarcity and Agency Reasons for Franchising

ENTREPRENEURSHIP THEORY AND PRACTICE, Issue 1 2006
Gary J. Castrogiovanni
Alternative explanations of franchising offer contrasting predictions as to how the proportion of franchised outlets changes as franchisors age. We propose that two dominant views,resource-scarcity and agency theory,can be integrated by delineating when each is most relevant. Data from 102 franchisors over a 21-year period suggest that resource-scarcity considerations take precedence when franchisors are young, but that agency considerations prevail as franchisors age. Thus, the proportion franchised exhibits a cubic pattern as franchisors age,increasing rapidly at first, decreasing, and then increasing again. Future researchers and practitioners alike can benefit from understanding how the relative influences of resource and agency considerations shift over time. [source]


Resource Scarcity and Agency Theory Predictions Concerning the Continued Use of Franchising in Multi-outlet Networks

JOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 1 2006
Gary J. Castrogiovanni
A study of 439 franchisors was conducted to identify factors influencing changes in their propensity to franchise. Consistent with agency theory, franchisors with wide multinational scope were increasing their proportion of franchised outlets whereas franchisors with large outlets were emphasizing firm ownership. As predicted by resource scarcity theory, franchisors were decreasing their proportion franchised as they grew in size, although most of the decrease occurred while firms were relatively small. In contrast to resource scarcity theory, franchisors increased their proportion franchised over time. Key implications are that both agency and resource scarcity theories are needed to explain franchising, but perhaps future research should look beyond resource scarcities toward resource-based capabilities to better explain franchising decisions.

Examining Factors that Impact Mississippi Counties' Unreserved Fund Balance during Relative Resource Abundance and Relative Resource Scarcity

PUBLIC BUDGETING AND FINANCE, Issue 4 2009
LA SHONDA M. STEWART
Although using some of the same organizational and financial factors examined by prior researchers to build and test models that explain factors influencing change in the general fund unreserved balance for smaller, rural, and less affluent counties in Mississippi, the rationale of this study is to build additional support that applying the recommended 5,15 percent savings benchmark across all jurisdictions is not a sufficient guide. Overall, Mississippi counties maintain unreserved fund balances ranging from a negative balance to over one hundred percent of their current expenditures. Counties also increase reserves during times of relative resource abundance and decrease them during relative resource scarcity. Moreover, they tend to address short-term needs and resident demands when revenues are plentiful. During relative resource scarcity, however, they are more cost-conscious and focus on maintaining rather than expanding current expenditures. This research shows that counties using the Beat system, a political form of government, are more likely to behave more frugally than counties using a Unit system, an administrative form of government.

The role of organizational size in the adoption of green supply chain management practices in China

CORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 6 2008
Qinghua Zhu
Abstract Economic globalization, increasing resource scarcity and environmental degradation have caused green supply chain management (GSCM) to become an important competitive approach for organizations involved in international trade. Using survey data collected from over 200 China-based organizations, we compare the implementation levels of five GSCM practices among small-, medium- and large-sized organizations in China. We find that medium- and large-sized organizations are more advanced than their smaller-sized counterparts on most aspects, but not necessarily all, of these GSCM practices. Future research includes possible studies on GSCM practices and promotion, especially targeting small manufacturing organizations. In addition, the influence of globalization and foreign direct investment, especially after China's entry into the WTO, could be more carefully examined.

Competition in variable environments: experiments with planktonic rotifers

FRESHWATER BIOLOGY, Issue 6 2002
KEVIN L. KIRK
1.,In a constant environment, competition often tends to reduce species diversity. However, several theories predict that temporal variation in the environment can slow competitive exclusion and allow competing species to coexist. This study reports on laboratory competition experiments in which two pairs of planktonic rotifer species competed for a phytoplankton resource under different conditions of temporal variability in resource supply. 2.,For both species pairs, Keratella cochlearis dominated under all conditions of temporal variability, and the other species (Brachionus calyciflorus or Synchaeta sp.) almost always went extinct. Increasing temporal variation in resource supply slowed competitive exclusion but did not change competitive outcome or allow coexistence. 3.,Rotifers show a gleaner,opportunist trade-off, because gleaner species have low threshold resource levels (R*) and low maximum population growth rates, while opportunist species have the opposite characteristics. In the competition experiments, the gleaner always won and the opportunists always lost. Thus, a gleaner,opportunist trade-off was not sufficient to facilitate coexistence under conditions of resource variability. Instead, the winning species had both the lowest R* and the greatest ability to store resources and ration their use during times of extreme resource scarcity. [source]


Unpacking the effect of IT capability on the performance of export-focused SMEs: a report from China

INFORMATION SYSTEMS JOURNAL, Issue 4 2008
Man Zhang
Abstract., Export-focused small and medium-sized enterprises (SMEs) in China face a number of barriers to success, two primary ones being the liability of foreignness and resource scarcity. In order to transcend these challenges and be able to survive/prosper in the hypercompetitive international market, where players include large resourceful multinational organizations with experience in varied national contexts, these firms need to develop different organizational capabilities. In this paper, we specifically examine the role of a key organizational capability , information technology (IT) capability , and its different dimensions, in determining performance of export-focused SMEs in China. Our study reveals that IT capability has a positive impact on such firms' performance. This finding indicates the need for their owners/managers to invest in IT capability. Further, the study also highlights specific sub-dimensions of IT capability that export-focused Chinese SMEs should (or should not) develop, so as to derive maximum performance-related gains for the minimum amount spent on IT.

Pseudoparadoxical impulsivity in restrictive anorexia nervosa: A consequence of the logic of scarcity

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 4 2002
Daniel M. T. Fessler
Abstract Objective To explain an apparently paradoxical pattern wherein sufferers of restrictive anorexia nervosa exhibit both rigorous self-restraint and episodic impulsivity. Method The experimental, historical, and clinical literatures were examined for evidence of psychological and behavioral changes accompanying severe dietary constriction; such changes were noted and compared with those reported to occur in anorexics. Results Increased impulsivity in association with dietary constriction is described in diverse literatures. A number of lines of evidence suggest that the serotonergic system mediates this change. Discussion Many forms of impulsivity can be understood as having once constituted fitness-enhancing responses to resource scarcity. It is suggested that an evolved psychological mechanism calibrates the individual's sensitivity to risk in light of future prospects. Self-injurious behaviors are explicable as misfirings of such a mechanism. Similarly, excessive exercising by anorexics may reflect the misdirection of reward systems that normally encourage adaptive increases in ranging behavior under conditions of scarcity. © 2002 by Wiley Periodicals, Inc.

CEO Duality and Firm Performance during China's Institutional Transitions

MANAGEMENT AND ORGANIZATION REVIEW, Issue 2 2007
Mike W. Peng
abstract Does CEO duality , the practice of one person serving both as a firm's CEO and board chair , contribute to or inhibit firm performance? Agency theory suggests that CEO duality is bad for performance because it compromises the monitoring and control of the CEO. Stewardship theory, in contrast, argues that CEO duality may be good for performance due to the unity of command it presents. The empirical evidence, largely from developed economies, is largely inconclusive. This article joins the debate by extending empirical work to the largely unexplored context of institutional transitions. Our findings, based on an archival database covering 403 publicly listed firms and 1,202 company-years in China, offer stronger support for stewardship theory and relatively little support for agency theory. Finally, we also call for a contingency perspective to specify the nature of conditions such as resource scarcity and environmental dynamism under which CEO duality may be especially valuable.

Detecting the effects of introduced species: a case study of competition between Apis and Bombus

OIKOS, Issue 3 2006
Diane M. Thomson
Developing tools for rapid assessment of introduced species impacts is one of the most important challenges in invasion ecology. Most assessments of impact rely on correlational data or other indirect measures. Yet few studies have evaluated invasion effects using multiple, simultaneously applied monitoring and experimental approaches, in order to compare easily obtained metrics with more difficult but direct measures of reproductive success or population dynamics. In this study, I use data from an experimental test of introduced honey bee (Apis mellifera) impacts on native bumble bees (Bombus spp.) to address two major questions: 1) how well did observational data on niche overlap and spatial correlations between Apis and Bombus predict the results of experimental tests of competitive effects? and 2) how well did effects of the experimental Apis manipulations on Bombus foragers, which are easy to observe, predict changes in reproductive success of colonies, which are difficult to measure? Niche overlap between Apis and Bombus varied substantially, but increased to levels as high as 80,90% during periods of resource scarcity. Correlations between numbers of Apis foragers and numbers of Bombus foragers were also highly variable, but I detected a significant negative relationship in only one of the seven months observed. In contrast, the experimental results showed that mean numbers of Bombus foragers observed on a given transect increased significantly with greater distance from introduced Apis colonies. Of these three measures (niche overlap, correlations in abundances, and effects of experimental introductions), only the experimental data on forager abundances accurately estimated competitive effects on colony reproductive success previously reported for the same experiment, and the correlational data in particular completely failed to predict the effects observed in the experimental study. This work suggests that great caution is warranted in making assessments of invasion impact on the basis of spatial or temporal correlations between invasive and native species. Thus, investing in even small and limited experimental studies may be more valuable than extensive observational work in quantifying invasion impacts. [source]

Activity budgets and activity rhythms in red ruffed lemurs (Varecia rubra) on the Masoala Peninsula, Madagascar: seasonality and reproductive energetics

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 1 2005
Natalie Vasey
Abstract The activity budgets and daily activity rhythms of Varecia rubra were examined over an annual cycle according to season and reproductive stage. Given the relatively high reproductive costs and patchy food resources of this species, I predicted that V. rubra would 1) travel less and feed more during seasonal resource scarcity in an attempt to maintain energy balance, and 2) show sex differences in activity budgets due to differing reproductive investment. Contrary to the first prediction, V. rubra does not increase feeding time during seasonal food scarcity; rather, females feed for a consistent amount of time in every season, whereas males feed most during the resource-rich, hot dry season. The results are consistent with other predictions: V. rubra travels less in the resource-scarce cold rainy season, and there are some pronounced sex differences, with females feeding more and resting less than males in every season and in every reproductive stage except gestation. However, there are also some provocative similarities between the sexes when activity budgets are examined by reproductive stage. During gestation, female and male activity budgets do not differ and appear geared toward energy accumulation: both sexes feed and rest extensively and travel least during this stage. During lactation, activity budgets are geared toward high energy expenditure: both sexes travel most and in equal measure, and rest least, although it remains the case that females feed more and rest less than males. These similarities between female and male activity budgets appear related to cooperative infant care. The high energetic costs of reproduction in V. rubra females may require that they allot more time to feeding year round, and that their overall activity budget be more directly responsive to seasonal climate change, seasonal food distribution, and reproductive schedules.

Trophic-dynamic considerations in relating species diversity to ecosystem resilience

BIOLOGICAL REVIEWS, Issue 3 2000
KRIS H. JOHNSON
ABSTRACT Complexity in the networks of interactions among and between the living and abiotic components forming ecosystems confounds the ability of ecologists to predict the economic consequences of perturbations such as species deletions in nature. Such uncertainty hampers prudent decision making about where and when to invest most intensively in species conservation programmes. Demystifying ecosystem responses to biodiversity alterations may be best achieved through the study of the interactions allowing biotic communities to compensate internally for population changes in terms of contributing to ecosystem function, or their intrinsic functional redundancy. Because individual organisms are the biologically discrete working components of ecosystems and because environmental changes are perceived at the scale of the individual, a mechanistic understanding of functional redundancy will hinge upon understanding how individuals' behaviours influence population dynamics in the complex community setting. Here, I use analytical and graphical modelling to construct a conceptual framework for predicting the conditions under which varying degrees of interspecific functional redundancy can be found in dynamic ecosystems. The framework is founded on principles related to food web successional theory, which provides some evolutionary insights for mechanistically linking functional roles of discrete, interacting organisms with the dynamics of ecosystems because energy is the currency both for ecological fitness and for food web commerce. Net productivity is considered the most contextually relevant ecosystem process variable because of its socioeconomic significance and because it ultimately subsumes all biological processes and interactions. Redundancy relative to productivity is suggested to manifest most directly as compensatory niche shifts among adaptive foragers in exploitation ecosystems, facilitating coexistence and enhancing ecosystem recovery after disturbances which alter species' relative abundances, such as extinctions. The framework further explicates how resource scarcity and environmental stochasticity may constitute ,ecosystem legacies' influencing the emergence of redundancy by shaping the background conditions for foraging behaviour evolution and, consequently, the prevalence of compensatory interactions. Because it generates experimentally testable predictions for a priori hypothesis testing about when and where varying degrees of functional redundancy are likely to be found in food webs, the framework may be useful for advancing toward the reliable knowledge of biodiversity and ecosystem function relations necessary for prudent prioritization of conservation programmes. The theory presented here introduces explanation of how increasing diversity can have a negative influence on ecosystem sustainability by altering the environment for biotic interactions - and there by changing functional compensability among biota - under particular conditions.
