Many companies decide which services, products, and technologies to include in their product portfolio using evaluation criteria, which often consider cost, quality, risk, revenue, time, and market position. Incorporating sustainability in the portfolio evaluation criteria could ensure the development of sustainable solutions from the early stages of the product development process, where there is more room for innovation. The aim of this paper is to understand how sustainability can be integrated in the company portfolio development. Semi-structured interviews were performed with experts in the field and representatives from multinational manufacturing companies with operations in Sweden. Main findings from this study include a proposed definition of a sustainability product portfolio concept and suggested portfolio evaluation criteria from an industry perspective. Future research will develop a method to guide manufacturing companies in sustainability integration and implementation in product portfolios.  相似文献

This paper considers semiparametric identification of structural dynamic discrete choice models and models for dynamic treatment effects. Time to treatment and counterfactual outcomes associated with treatment times are jointly analyzed. We examine the implicit assumptions of the dynamic treatment model using the structural model as a benchmark. For the structural model we show the gains from using cross-equation restrictions connecting choices to associated measurements and outcomes. In the dynamic discrete choice model, we identify both subjective and objective outcomes, distinguishing ex post and ex ante outcomes. We show how to identify agent information sets.  相似文献

Abstract

This article investigates how price and brand loyalty of three frequently purchased product categories can influence the purchase decision process of store brands versus national brands. A multinomial logit model was constructed to analyse the data obtained from a consumer panel. The results confirmed that brand loyalty is the main variable which influences the purchase decision process of both national and store brands. The influence of price on the purchase decision process is product specific. There is a clear distinction between the buyer's profile of store brands and national brands. But there is no evidence of any correlation between demographic variables and national brands or store brands.  相似文献

Living in inadequate housing conditions not only supposes a failure of a basic functioning. It also has effects on other essential aspects of well-being such as health. This study questions to what extent living in poor housing conditions can determine individuals’ health status once the possible influence of other factors is controlled for. By estimating a logistic model with individual effects and a housing deprivation index based on a latent variable model, we reach a number of relevant conclusions concerning the relationship between these two different dimensions of multidimensional well-being. We find a negative effect of housing deprivation on the individuals’ health, both when housing conditions are introduced in a disaggregated manner in the model and when they are combined in a latent variable.  相似文献

Do contemporary governments adapt to rising social movements or do they actually cause them? This paper endeavours to argue that although it is often difficult to determine the origins of social transformations, there are reasons to believe that there exists not only a co-option but also a conscious shaping of social changes by political projects or governments for their own benefit. Building on other contributions that state that popular culture and youth consumerism are used in favour of nation branding, the present study moves beyond this to analyse the active role that governments play in the marketisation and consumption of culture, thus artificially multiplying the effective impact of some cultural waves that ultimately serve political purposes. In particular, I examine the so-called “Cool Britannia” phenomenon that, founded on the flourishing of new creative industries, with Britpop in the lead, had a significant historic impact in Britain.  相似文献

Biofortified staple foods are currently being developed to reduce problems of micronutrient malnutrition among the poor. This partly involves use of genetic modification. Yet, relatively little is known about consumer acceptance of such second‐generation genetically modified (GM) foods in developing countries. Here, we analyse consumer attitudes towards provitamin A GM cassava in the north‐east of Brazil. Based on stated preference data, mean willingness to pay is estimated at 60–70% above market prices for traditional cassava. This is higher than the results from similar studies in developed countries, which is plausible given that micronutrient malnutrition is more severe in developing countries. GM foods with enhanced nutritive attributes seem to be well received by poor consumers. However, the results also suggest that acceptance would be still higher if provitamin A were introduced to cassava through conventional breeding. Some policy implications are discussed.  相似文献

Electronic listening (eListening) is an innovation that potentially provides patients and other users with the right answer in the right place at the right time. Thus, eListening can potentially improve service flexibility, adaptability and quality. The main purpose of this paper is to investigate the extent to which new web-based service delivery channels, which we refer to as health-portals (he-portals), facilitate eListening in the Spanish public healthcare sector. In this paper, we investigate the relative importance and significance of hospital size and three different types of information and communications technologies (Internet, groupware and collective systems) on the use of eListening through an empirical investigation of 300 Spanish public he-portals. Our main conclusion is that the implementation of Internet systems alone does not guarantee the development of effective eListening. In addition, we demonstrate that hospital size does not affect the level of eListening achieved by hospitals.  相似文献

Most oil refineries and factories producing basic chemical products are located in port areas, with the result that industrial complexes potentially have a strong environmental impact on their area of influence. These externalities result in a loss of welfare for citizens residing in neighbouring areas. In a context of sustainable development, companies must integrate concerns about the natural environment in their business strategy. External stakeholders, as residents, find it difficult to visualize the actions firms take to reduce their environmental impact, and the adoption of voluntary certified environmental management systems (EMSs) acts as a signal indicating the adequate environmental behaviour of these companies. These certifications enable companies to achieve the social legitimacy they need for long‐term survival and competitiveness. In the context of a petrochemical industrial complex located in the port of Castellón (Spain), this paper primarily discusses whether such certifications – which act as signals of firms’ desirable environmental conduct – translate into higher trust in firms and lower risk perception by residents. Contrary to what might be expected, despite the widespread use by companies of voluntary and certified EMSs, the research findings confirm a relatively high citizen perception of risk regarding the industrial complex and a low trust in companies. On the other hand, the findings also show a low trust in the public institutions responsible for authorizing and monitoring firms’ activities and for enforcing possible sanctions in non‐compliance cases.

Using data from Bangladesh, this article finds that the liquidity premium – the difference between the interest paid on illiquid and liquid savings accounts – is higher in commercial banks than in microfinance institutions. One possible interpretation lies in the higher prevalence of time-inconsistency among the poor. The observed difference in liquidity premia could be due to poor time-inconsistent agents willing to forgo interest on illiquid savings accounts in order to discipline their future selves.  相似文献
