In this paper, field studies, extant literature, and domain knowledge are used to develop a theory of managing context in Six Sigma process-improvement projects. By means of a participatory action research investigation involving ten projects in manufacturing and service firms, this paper examines the interrelationship among project context, elements, and success. Rich text-based information for each project was analyzed for the underlying patterns and relationships using the NVIVO 8 qualitative data analysis software package. The insights gained from this in-depth field investigation are presented in the form of 12 inductively derived research propositions that, when taken together, uniquely contribute to context-based theory-building in this area. 相似文献

This article describes the implementation of an enterprise resource planning (ERP) implemented by British Petroleum (BP) Worldwide, from the perspective of one of its subsidiary organizations, BP Singapore. The ERP solution, an internally developed system, was implemented globally by BP worldwide quite successfully from a global perspective, though not without challenges at the local level. This study examines the process of implementing a global ERP solution at the local subsidiaries, and the unique problems that may be encountered in force-fitting a global solution at the local level. Among the issues and problems experienced by the subsidiary are higher-than-anticipated costs, longer development times, lack of technical expertise, and compromises in business processes. The findings of the study could be helpful in formulating coping mechanisms in implementing global ERP solutions. 相似文献

The effectiveness of pre-release advertising for motion pictures: An empirical investigation using a simulated market 总被引:2,自引:0,他引:2
We use data on a movie’s stock price as it trades on the Hollywood Stock Exchange, a popular online market simulation, to study the impact of movie advertising. We find that advertising has a positive and statistically significant effect on expected revenues, but that the effect varies strongly across movies of different “quality”. The point estimate implies that the returns to advertising for the average movie are negative. 相似文献

Summary We present an overlapping generations model of endogenous fertility and growth. The cost of child rearing and the effect of population size on total factor productivity determine the dynamics of competitive equilibrium path of our model. The non-linear dynamics of the model generates a plethora of outcomes (depending on the functional forms, parameters and initial conditions) that include not only the neo-classical steady state with exponential growth of population with constant per capita income and consumption, but also growth paths which do not converge to a steady state and are even chaotic. Exponential, and even super exponential, growth of per capita output are possible in some cases.We would like to thank Mukul Majumdar, Kazuo Nishimura and an anonymous referee for many comments. 相似文献

We estimate a translog production function based on data from a Japanese automobile plant in the Midwest where output is determined by capital and different supervisory time inputs. We fit a model which allows for heteroskedastic errors, where this heteroskedasticity is a function of various variables affecting perceived target severity. We find that while, as expected, capital inputs are important, each supervisory time input is also significant in this capital-intensive industry. Linear homogeneity in these inputs is rejected. We find evidence of asymmetry in substitution among different components of supervisory time. This asymmetry has implications for the design and allocation of supervisory tasks. © 1997 John Wiley & Sons, Ltd. 相似文献

We apply prospect theory to examining farmers’ economic incentives to divert a share of their land to bioenergy crops (miscanthus and switchgrass in this study). Numerical simulation is conducted for 1,919 rain‐fed U.S. counties to identify the impact of loss aversion on bioenergy crop adoption, and how this impact is influenced by biomass price, discount rate, credit constraint status, and policy instruments. Results show that ignoring farmer's loss aversion causes overestimation of miscanthus production but underestimation of switchgrass production, particularly when farmers are credit constrained and have a high discount rate. We find that establishment cost subsidy induces more miscanthus production whereas subsidized energy crop insurance induces more switchgrass production. The efficacy of these two policy instruments, measured by biomass production increased by per dollar of government outlay, depends on the magnitude of farmers’ loss aversion and discount rate. 相似文献

We use a sample of 816 diversifying takeovers from 1978 to 2003 to examine whether takeover announcements release negative information about the future prospects of the acquirer's main industry. We find that rivals that are most similar to the acquirer (homogeneous rivals) experience significant negative cumulative abnormal returns (CAR) around takeover announcements. Takeovers that result in negative wealth effects to acquirers are associated with negative abnormal revisions in analysts' forecasts of homogeneous rivals' earnings per share. We also find a decline in the posttakeover operating performance of rival firms. The decline is especially pronounced for homogeneous rivals and for takeovers with negative wealth effects to acquirers. Our findings imply that CAR-based estimates of acquirer wealth gains from takeovers that do not account for industrywide information releases are significantly biased downward. 相似文献

While many empirical studies document borrower benefits of lending relationships, less is known about lender benefits. A relationship lender's informational advantage over a non-relationship lender may generate a higher probability of selling information-sensitive products to its borrowers. Our results show that the probability of a relationship lender providing a future loan is 42%, while for a non-relationship lender, this probability is 3%. Consistent with theory, we find that borrowers with greater information asymmetries are significantly likely to obtain future loans from their relationship lenders. Relationship lenders are likely to be chosen to provide debt/equity underwriting services, but this effect is economically small. 相似文献
