We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting. 相似文献

Using subjective well-being estimations, this study analyzes whether compensating variations vary across space using a cross-sectional data set from Chile. To achieve this goal, it describes and compares two econometric ways of modelling unobserved spatial heterogeneity. Both approaches allow compensating variations to vary across spatial units by assuming some distribution a priori. One method assumes that the spatial heterogeneity can be represented by a discrete distribution (a group of regions that share the same coefficient) and the other that the preferences can be represented by a continuous distribution (each region has a different coefficient). The results show that focusing just on the average estimates of compensating variations, as the applied studies have done so far, masks useful local variation. More empirical studies are needed to assess the advantages and disadvantages of both econometric approaches and how their results compare across a wide range of conditions and samples. 相似文献

The article analyzes the interaction between employee ownership, HRM policies and practices, and HRM outcomes in what was the world's biggest industrial worker cooperative for decades, and now defunct, Fagor Electrodomésticos. Using longitudinal internal data and detailed interviews with key stakeholders, this paper sheds light on how employee ownership conditioned HRM policies. HRM outcomes—such as job satisfaction and absenteeism—are also analyzed over a long period of time. Chronic nepotism when recruiting new members, failures in the training policy, impoverished and Taylorist working systems, and reverse dominance hierarchies are analyzed as factors that increased free riding and caused low satisfaction and the disengagement of working members. This case study contributes to the literature on HRM and worker cooperatives as it provides some insights that are rarely found in that literature. It also provides guidance to worker cooperatives about increasing the fit between employee ownership and HRM policies and outcomes. 相似文献

AbstractAs human resource challenges have increased, strategic human resource management (SHRM) in hospitals has evolved into an important management task. Accompanying its growing relevance, there is an evolving research stream on the impact of SHRM on organizational and individual-level outcomes in the hospital context. We aim to address two remaining research gaps by investigating variations in the use of SHRM across organizations (public vs. private ownership types) and differences in the relationship between SHRM and employee attitudes within organizations (for the occupational groups of nurses and physicians). This study is based on a sample of 179 German acute care hospitals. We employ ANOVA and logistic regression analyses, and our results corroborate previous research findings showing that SHRM has positive effects on employee attitudes. However, the effects vary in significance and magnitude, depending on whether nurses or physicians are targets. Further, we reveal significant SHRM differences in public- vs. private-sector organizations. 相似文献

In this note oligopoly with iso‐elastic demand is analysed. Unlike previous studies we consider general iso‐elastic demand rather than the case of unit elasticity. An n‐firm Nash‐Cournot equilibrium for the case of heterogeneous constant marginal costs is derived. The main result is a closed‐form solution that shows the dependency of the equilibrium on the elasticity of demand and the share of industry costs. The result has applications to a wide range of areas in oligopoly theory by allowing comparisons across markets with different elasticities of demand. 相似文献

This study empirically examines the implementation of environmental policies and how government engagement impacts on a firm's environmental performance based on a sample of Chinese listed firms in the eight most polluting industries over a 10‐year period. The findings of the study demonstrate that government engagement, measured as ownership structure, is positively correlated with environmental performance, measured by environmental capital expenditure, for state‐owned firms, but no significant relation is found for non‐state‐owned firms. In addition, non‐state‐owned firms are more likely to perform better in terms of environmental investment after the 2006 enactment of a new policy explicitly linking environmental issues with political incentives to regional governments. This study also reports that corporate environmental performance impairs firm value for state‐owned firms but has no impact on firm value for non‐state‐owned firms, suggesting that investors negatively respond to environmental investments made by state‐owned firms as a result of government engagement/political pressure.

This paper uses a historical natural experiment – the opening of the Suez Canal – to investigate the relationship between geography and the formation of institutions. While the conventional view is that good geography (commodity endowment) inevitably favours the creation of extractive institutions, we discover that a second aspect of geography – location – may in fact encourage the establishment of non-extractive institutions when rent extraction by elites depends on the productivity of non-elites. Specifically, we find that entrepôt colonies (Hong Kong and the Straits Settlements) received larger public investments in the post-Suez period than resource colonies (British India, Ceylon, and West Africa), after accounting for year effects and permanent differences across colonies. We demonstrate, using supplementary data, that the entrepôt colonies' locational advantage, coupled with their lack of extractable resources, plays a key role in explaining our empirical findings. 相似文献
