Emerging markets offer tremendous growth opportunities for firms. While established multinational firms typically focus on premium segments in emerging markets, they often fail to leverage additional growth opportunities in so‐called good enough or low‐income segments in emerging markets. Customers in these low‐income markets have substantially different requirements and are very price sensitive. Theoretical and case‐based research suggests that innovating for these low‐income segments in emerging markets differs significantly from innovating for premium or traditional Western markets. We argue that tapping successfully into low‐income segments in emerging markets requires the development of new products that meet the low price expectations while at the same time offering also value to customers in these segments. We refer to these new products as affordable value innovations. We analyze the antecedents of affordable value innovation for emerging markets. We draw on institutional theory to derive three potentially relevant antecedents of affordable value innovation for emerging markets. These are bricolage, local embeddedness, and standardization. We test our hypotheses using multiple informant data from 47 multinational corporations involving 103 innovation projects that target low‐income customers in emerging markets. Our empirical analysis shows that all three antecedents have significant effects on the level of affordable value innovation: while bricolage and local embeddedness are positively related to the level of affordable value innovation, standardization has a negative impact. We also examine the relationship between the level of affordable value innovation and performance. We find evidence for our basic assumption that a firm's capability to develop and launch affordable value innovations is key to success in emerging markets. It indicates that a firm's investments in affordable value innovations for emerging markets pay off financially. Finally, a cross‐regional comparison of our data shows that the key findings on antecedents of affordable value innovation and its impact on performance do not vary across various emerging markets. Overall, our findings offer important implications for research on and the practice of innovation for low‐income segments in emerging markets.  相似文献

This paper introduces a key methodological innovation into generational accounting. By incorporating cyclically‐adjusted balances into the forward‐looking budget projections underlying the concept, we isolate pure policy effects, which render comparisons of the fiscal sustainability indicators obtained across time and countries truly meaningful. We also show that a demographic effect and a debt effect may drive fiscal sustainability measures over time, and establish a routine to control for these effects in the generational accounting framework. An empirical application for Spain illustrates that our proposed decomposition of indicators is empirically relevant. Standard generational accounting suggests that fiscal sustainability in Spain improved substantially in preparing for EMU. However, calculation of the pure policy effects reveals that this has not been the case.  相似文献

This article explores the adoption of new technology in organisations that provide senior citizen care. Inspired by Niklas Luhmann’s systems theory, we study how technology reduces complexity by identifying client needs and ensuring predictability in service delivery. However, how technologies are adopted in practice is not determined by technology since it is also structured by care-workers' continuous decision-making. Against this backdrop, we explore how technologies alter the conditions for decision-making in two settings of elderly care, and we describe how care workers seek to adapt technologies to their practical needs as well as conception of care ethics. Developing a systems theory approach, the article eschews a priori assumptions of technological constraint on care-workers’ professional autonomy, offering a more open-ended exploration of diversified strategies for coping with new technology. Our case studies show that employees develop diversified strategies for technology adoption, including both non-usage, heated resistance, excessive embrace, and creative adaption.  相似文献

Given an investor maximizing utility from terminal wealth with respect to a power utility function, we present a verification result for portfolio problems with stochastic volatility. Applying this result, we solve the portfolio problem for Heston's stochastic volatility model. We find that only under a specific condition on the model parameters does the problem possess a unique solution leading to a partial equilibrium. Finally, it is demonstrated that the results critically hinge upon the specification of the market price of risk. We conclude that, in applications, one has to be very careful when exogenously specifying the form of the market price of risk.  相似文献

This article describes the results of a scientific discourse which aimed at exploring the reasons for differences in expert health risk assessment of radio frequency electromagnetic fields of mobile telephony.

It starts with describing the structure of the discourse. Then, the reasons for the conflicting risk assessments are discussed. Differences are due to the selection and evaluation of relevant scientific studies by applying different scientific quality standards, to the methods used for generating a research synthesis and an overall risk evaluation. Consensus could be achieved regarding the selection of and the quality requirements for the scientific studies used for risk assessment as well as their significance for risk evaluation. However, dissent remained about the synthesis of scientific evidence into an overall risk evaluation and about the relevance of the precautionary principle for risk evaluation and its implications for the risk assessment framework.

Based on the analysis of these problems, a transparent, consistent and rational procedure for risk assessment is suggested to facilitate a risk characterization which better meets the demands of policy making and the public for an appropriate risk evaluation.  相似文献

Besides applying knowledge in their own products or services, firms may externally commercialize their knowledge assets (e.g., by means of outlicensing). The literature on champions, however, has focused on internal innovation. This gap in prior research is particularly remarkable as the potential for promoting external knowledge exploitation is high. Some pioneering firms realize great benefits, whereas most others experience major managerial difficulties. This paper tests five hypotheses regarding the emergence and impact of champions of external knowledge exploitation with data from 152 firms across industries. The results of the questionnaire‐based study demonstrate the relevance of champions of external knowledge exploitation. Championing constitutes an essential success factor and has strongly contributed to the recent increase in external knowledge commercialization. These findings help to explain the discrepancies between the few successful and the majority of unsuccessful firms. Beyond existing insights, the emergence of champions is affected by external determinants in addition to internal determinants. There is an inverted U‐shaped relationship between championing and the internal determinants, that is, organizational climate and active strategy. Moreover, there is a negative relationship between championing and market imperfection and an inverted U‐shaped relationship between championing and competitive intensity, which both constitute external determinants of championing. In contrast to the traditional understanding, champions tend to emerge in supportive environments, in which internal and external barriers are relatively low. This surprising finding calls for rethinking the role and motivation of champions.  相似文献

In this study we draw on the literature of emotions and entrepreneurial motivation to analyze how and why emotional displays of managers influence the willingness of employees to act entrepreneurially. Using an experimental design and 2912 assessments nested within 91 employees from 31 small entrepreneurially oriented firms, we find that managers' displays of confidence and satisfaction about entrepreneurial projects enhance employees' willingness to act entrepreneurially, whereas displays of frustration, worry, and bewilderment diminish employees' willingness. Moreover, we find that displays of satisfaction, frustration, worry, and bewilderment moderate the effect of managers' displayed confidence on employees' willingness to act entrepreneurially. Our findings have implications for the emotions and entrepreneurial motivation literature.  相似文献
