This article investigates the issue of commitment by a durable goods monopolist. Two models of the interaction between durability, recycling, and market power are compared. The two differ according to the ability of the seller to credibly commit to a given sales strategy. This article takes the standard durable goods monopoly model, extends it to allow for depreciation, and compares the monopoly markup with Swan's predicted markup for a recycled good. The difference between the two models is shown to reduce to a single parameter in the markup equation.  相似文献

This paper contributes to the understanding of the executive team dynamic managerial capabilities by developing theory about the interplay between the firm's dominant logic and dynamic managerial capabilities (including managerial human capital, social capital, and cognition). We underscore the criticality of the two key CEO‐level functions: configuration and orchestration of senior executive team dynamic capabilities. We develop theory on how these functions create and sculpt the management team's absorptive capacity, which in turn shapes the team's adaptive capacity. We present theory about the distributed nature of efforts for organizational renewal where CEO's dynamic managerial capabilities in concerto with senior executive managerial capabilities will drive top management's ability to revitalize the firm's dominant logic and to achieve evolutionary fit.

With the changing way people live, communicate, and work, enterprises are striving to shift their existing business model into a “self‐tuning” one. Enterprises are becoming more agile, adaptive, and ambidextrous in order to boost innovation in the current digital transformation era. Nowadays, “digital innovation” is closely associated with Industry 4.0 enablers and smart enterprises. Prior research has shown that while multinational enterprises—across many sectors—have already embraced the aforementioned advancements, their adoption by small and‐medium‐sized enterprises (SMEs) has so far taken place mainly in the manufacturing sector. Thus, based on a sample of 280 self‐tuned smart manufacturing SMEs and having utilized the structural equation modeling (SEM), this study was aimed to investigate how digital innovation is influenced by the three pillars of self‐tuning models—agility, adaptation, and ambidexterity. Our paper has focussed on the digital systems in which SMEs, spurred by networking and open innovation solutions, operate and innovate in response to external triggers, displaying a balance between exploration and exploitation, and a strong agile capacity.  相似文献

Conclusions It has been demonstrated that in the case of Nigeria, planning without an econometric forecasting model was a good decision as far as the models tested could show. However, this may be a confirmation of the fears entertained by certain experts that the developing economies are not suitable for such exercises.Well, there are other types of planning models: the input-output type and its extension to mathematical programming, which have not been tried and tested. But as of now, we can conclude that econometric forecasting model should not be used for planning in Nigeria until they are well improved and well tested, else greater distortions may be introduced than by planning without a model.The author is indebted to Professor T.O.M. Kronsjö, University of Birmingham, for valuable comments. This project has been financed by NISER.  相似文献

The beef production function of different enterprises has been estimated for the sample farms in Nova Scotia. The returns to scale and marginal productivity of resources are derived from the production functions. It indicates decreasing returns to scale and the low marginal productivities of grain, labor, and variable costs for all enterprises. Grain and hay are the most important feeds for beef production. Many beef farms in the province produce more roughage than grain. The marginal rate of substitution of hay for grain is diminishing. Beef farmers can produce equal amounts of product with different combinations of the two feeds. The results provide the possibility of finding the least-cost combination of inputs. This study has specified the optimum input levels under different prices of inputs. It will help beef farmers to allocate their resources properly in order to maximize profits. Les fonctions de production de boeuf de différentes entreprises ont été eslimées à partir de fermes selectionées en Nouvelle-Ecosse. Les économies ?échelle et la productivté marginale des ressources sont dérivées des fonctions de production. On retrouve dans toutes les entreprises des économies ?échelle décroissantes et une faille productivity marginale du grain, du travail et des couts variables. Le grain el le foin constituent la plus importanle source ?alimentation dans la production de boeuf. Plusieurs fermes ?élevage de boef produisent plus de fourrage que de grain. Le laux marginal de substitution du foin pour le grain va en diminuant. Les éleveurs de boeuf peuvent produire des quantités egales par des combinaisons différentes de ces deux aliments. Les résultats ptrmettent de déterminer la combinaison la moins coûteuse pour la consommation des aliments, Cette étude a détérmine les niveaux optime de consommation selon les différents prix des aliments. Elle aidera les producteurs de boeuf à distribuer adéquatement les aliments afin de maximiser les profits.  相似文献
