Firms need to show dynamic adaptability and innovate their business models to achieve survival and growth, in particular when they are exposed to high levels of exogenous change. However, business model innovation also takes place in the absence of exogenous change. We know relatively little about firms’ approaches to opportunities for business model innovation in both of these environmental settings. The objective of this study is to understand how firms exposed to various environmental conditions explore and exploit business model innovation opportunities. In a qualitative multiple case analysis, the study compares the approaches to business model innovation used by four firms exposed to high levels of exogenous change with those of four firms operating in the absence of exogenous change. The findings are contrasted with entrepreneurial opportunity discovery and creation theories. The results reveal that firms exposed to high levels of exogenous change focus on discovering objective opportunities, whereas firms operating in the absence of exogenous change concentrate on creating opportunities for business model innovation. However, this study revealed that when the firms further explore and exploit these opportunities, they tend to combine the behaviours that the two opportunity perspectives suggest. This study contributes to the literature on business model innovation by emphasising the relationship between environmental context and approach to business model innovation and by reinforcing the link with entrepreneurship theory. 相似文献

This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students. 相似文献

Absolute and Relative Deprivation and the Measurement of Poverty 总被引:2,自引:0,他引:2
This paper develops the link between poverty and inequality by focussing on a class of poverty indices (some of them well–known) which aggregate normative concerns for absolute and relative deprivation. The indices are distinguished by a parameter value that captures the ethical sensitivity of poverty measurement to "exclusion" or "relative–deprivation" aversion. The indices can be readily used to predict the impact of growth on poverty. An illustration using LIS data finds that the United States show more relative deprivation than Denmark and Belgium whatever the percentiles considered, but that overall deprivation comparisons of the four countries considered will generally depend on the intensity of the ethical concern for relative deprivation. The impact of growth on poverty also depends on the presence of and on the attention granted to concerns over relative deprivation. 相似文献

This paper examines 2 years of data from GEM Canada in order to develop new insights into the factors that contribute to the
performance outcomes of female enterprises and how these factors are affected by the firm’s stage of development. The analysis
encompasses both personal and organizational characteristics and assesses their association with selected performance measures
at the early stage as well as at the established phase of development. The findings indicate that the greater propensity of
men to pursue business growth and earnings can be attributed to marital status (live with a partner) and the expected depth
of the ownership team. Moreover, the performance outcomes for male entrepreneurs are influenced by a relatively wide range
of variables, with business demographics being more prominent than for the female enterprises. For both genders, the mix of
relevant underlying factors varies as the venture progresses along the ‘nascent-new-established’ continuum. 相似文献

This article reviews the dynamic evolution of personality research and practice in work organizations from the early 1900s through the present. The article reveals steady‐state equilibrium in the world of practice. In contrast, the world of research is shown to be punctuated by rapid changes in conceptual foci, levels of analysis, and methodological approaches, as well as whether or not personality at work is even considered important. Explanations are offered for these trends, including the ways theory and research in the larger world of the study of personality have been reflected in personality research in and on work organizations. The article concludes with some thoughts about revisiting various branches in this evolution and suggestions for the future of personality research and practice in work organizations. © 2007 Wiley Periodicals, Inc. 相似文献

A group of agents located along a river have quasi-linear preferences over water and money. We ask how the water should be allocated and what money transfers should be performed. The core lower bounds require that no coalition should get less than the welfare it could achieve by using the water it controls. The aspiration upper bounds demand that no coalition enjoy a welfare higher than what it could achieve in the absence of the remaining agents. Exactly one welfare distribution satisfies the core lower bounds and the aspiration upper bounds: it is the marginal contribution vector corresponding to the ordering of the agents along the river.

Use of biofuels diminishes fossil fuelcombustion thereby also reducing net greenhousegas emissions. However, subsidies are
neededto make agricultural biofuel productioneconomically feasible. To explore the economicpotential of biofuels in a greenhouse
gasmitigation market, we incorporate data onproduction and biofuel processing for thedesignated energy crops switchgrass,
hybridpoplar, and willow in an U.S. AgriculturalSector Model along with data on traditionalcrop-livestock production and processing,
andafforestation of cropland. Net emissioncoefficients on all included agriculturalpractices are estimated through crop growthsimulation
models or taken from the literature. Potential emission mitigation policies ormarkets are simulated via hypothetical carbonprices.
At each carbon price level, theAgricultural Sector Model computes the newmarket equilibrium, revealing agriculturalcommodity
prices, regionally specificproduction, input use, and welfare levels,environmental impacts, and adoption ofalternative management
practices such asbiofuel production. Results indicate no rolefor biofuels below carbon prices of $40 perton of carbon equivalent.
At these incentivelevels, emission reductions via reduced soiltillage and afforestation are more costefficient. For carbon
prices above $70,biofuels dominate all other agriculturalmitigation strategies. 相似文献

Economic theory suggests that it is optimal to reward teachers depending on the relative performance of their students. We develop an econometric approach, based on stochastic frontier analysis, to construct a fair ranking that accounts for the socio-economic background of students and schools and the imprecision inherent in achievement data. Using German PIRLS (IGLU) data, we exploit the hierarchical structure of the data to estimate the efficiency of each teacher. A parsimonious set of control variables suffices to get a “fair” estimate of unobserved teacher quality. A Hausman–Taylor type estimator is the preferred estimator because teacher efficiency and some exogenous variables may be correlated. 相似文献
