Extended producer responsibility (EPR) programs typically hold the producer—a single actor defined by the regulator—responsible for the environmental impacts of end‐of‐life products. This is despite emphasis on the need to involve all actors in the supply chain in order to best achieve the aims of EPR. In this paper, we examine the economic and environmental implications of product recovery mandates and shared responsibility within a supply chain. We use a two‐echelon model consisting of a supplier and a manufacturer to determine the impacts of product collection and recycling mandates on the incentive to recycle and resulting profits in the integrated and decentralized supply chains. For the decentralized supply chain, we demonstrate how the sharing of responsibility for product recovery between the echelons can improve total supply chain profit and suggest a contract menu that can Pareto‐improve profits. To examine both the economic and environmental performance associated with responsibility sharing, we propose a social welfare construct that includes supply chain profit, consumer surplus, and the externalities associated with virgin material extraction, product consumption, and disposal of nonrecycled products. Using a numerical example, we discuss how responsibility sharing may or may not improve social welfare. The results of this paper are of value to firms either anticipating or subject to product recovery legislation, and to social planners that attempt to balance economic and environmental impacts and ensure fairness of such legislation. 相似文献

Firms often determine whether or not to make components common across products by focusing on the manufacturing and sales of new products only. However, component commonality decisions that ignore remanufacturing can adversely affect the profitability of the firm. In this article we analyze how remanufacturing could reverse the OEM's commonality decision that is based on the manufacturing and sales of new products only. Specifically, we determine the conditions under which the OEM's optimal decision on commonality may be reversed and illustrate how her profit can be significantly higher if remanufacturing is taken into account ex ante. We illustrate the implementation of our model for two products in the Apple iPad family. 相似文献

This note is concerned with presenting some simple indices of group-wise relative disadvantage in the distribution of income,
in terms of the distance between the group’s share in total population and its share in total income. The group-wise indices
are then aggregated into society-wide indices of inter-group disparity. Empirical illustrations of the note’s measurement
concerns are provided, using data on the global distribution of income. The measures of horizontal inequality are shown to
lead to corresponding measures of vertical inequality, in the special case in which the grouping resorted to is ‘individualistic’. 相似文献

This note proposes a principle of liberalism which is a simple and plausible variant of Sen's principle of minimal liberalism. The former principle is shown to be incompatible with the weak Pareto principle; and this impossibility result is not dependent on the preference-aggregating rule being restricted by any collective rationality condition. 相似文献

The main objective of this research is to highlight the need to reconceptualize the theoretical construct of innovativeness. There is a large body of research on the adoption of innovations. Although research studies in this area are motivated by fundamentally different objectives, there is a common thread that runs through all of them—the identification of innovative firms.In order to identify innovative firms, a variety of unidimensional measures of innovativeness have been employed in past research. Thus, innovation diffusion research studies have used the time of innovation adoption as a measure of a firm's innovativeness. Other studies have assessed innovativeness on the basis of the number of innovation adoptions. This research contends that the conceptualization of innovativeness as a unidimensional construct is incomplete. Innovativeness, we believe, is an enduring trait that is consistently exhibited by innovative firms over a period of time. In other words, a valid measure of innovativeness must represent this temporal dimension. This study proposes and tests the validity of a multidimensional measure of innovativeness. 相似文献

In the analysis of censored survival data, simultaneous confidence bands are useful devices to help determine the efficacy of a treatment over a control. Semiparametric confidence bands are developed for the difference of two survival curves using empirical likelihood and compared with the nonparametric counterpart. Simulation studies are presented to show that the proposed semiparametric approach is superior, with the new confidence bands giving empirical coverage closer to the nominal level. Further comparisons reveal that the semiparametric confidence bands are tighter and, hence, more informative. For censoring rates between 10 and 40 %, the semiparametric confidence bands provide a relative reduction in enclosed area amounting to between 2 and 10 % over their nonparametric bands, with increased reduction attained for higher censoring rates. The methods are illustrated using an University of Massachusetts AIDS data set. 相似文献

We introduce borrowing constraints into a two‐sector Schumpeterian growth model and examine the impact of asset price bubbles on innovation. In this environment, rational bubbles arise when the intermediate good producing R&D sector is faced with adverse productivity shocks. Importantly, these bubbles help alleviate credit constraints and facilitate innovation in the stagnant economy. On the policy front, we make a case for debt financed credit to the R&D sector. Further, we establish that a constant credit growth rule (akin to the Friedman rule) outperforms the often prescribed counter‐cyclical “lean against the wind” credit policy. (JEL E32, E44, O40) 相似文献

AbstractThis study, drawing on natural resource-based view, identifies drivers, barriers and the potential benefits of returnable transport packaging (RTP) – that is, the repeated use of packaging items – and conceptualises RTP as a technology and resource that supports organisational competitiveness. Specifically, it investigates the impact of RTP adoption on business performance, the effects of drivers, barriers and size of organisations. The data collection took place in Nigeria and South Africa. The findings suggest that RTP has a significant positive impact on business performance. Whilst prior studies seem to suggest that shrinkage and attrition are the major problems identified with the usage of RTP, our findings indicate that there are several other barriers affecting RTP adoption and the resultant performance advantage. The results also show that there is an increasing move towards adoption of RTP but some organisations are faced with financial constraints, especially the small and medium size enterprises. In addition, the results show that RTP is largely a ‘sustainability facing’ initiative with adopters motivated primarily by potential environmental, economic, social and operational benefits of adoption. 相似文献
