Issues in evaluating marketing performance and devising appropriate metrics for measurement have taken center stage in marketing thought and practice in recent years. We propose an empirical model that enables a multinational enterprise (MNE) to assess the marketing performance of its subsidiaries, taking into explicit consideration the fact that tactical actions by subsidiaries contribute to the creation of assets that can be harnessed for marketing outcomes. Thus, our model captures the asset creation abilities of marketing expenditures and also takes in to account the environmental differences of the context in which each MNE subsidiary operates. We evaluate comparative, overall, and process-level (creation of market assets and market yield) marketing performance in the context of multi-country operations. This simultaneous examination of marketing process and marketing outcome performance enables a global corporation to gain strategic, operational, and diagnostic insights into the performance of its subsidiaries. Our approach is empirically illustrated with an evaluation of the marketing performance of subsidiaries of a large global corporation.  相似文献

With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies.  相似文献

This paper examines the financial and operational hedging activities of US pharmaceutical and biotech firms that are subject to a high level of information asymmetry stemming from R&D investments during 2001–2006. We find evidence in support of the information asymmetry hypothesis à la Froot, Scharfstein and Stein (1993) that hedging helps mitigate the under‐investment problem. Specifically, we find that the use of financial derivatives is associated with greater firm value and that the value enhancement is larger for firms subject to greater information asymmetry and better growth opportunities. There is a synergy between financial hedging and operational hedging where the latter is used to counter product development risk. The results are robust with respect to alternative performance measures, industry‐specific growth measures, and the endogeneity problem. Our work is differentiated from existing studies that examined commodity‐based industries without addressing information asymmetry.  相似文献

We examine sourcing professionals’ work context to conceptualize how they use sourcing enterprise systems (SESs) and to understand when SES use results in positive/negative job outcomes. We differentiate between SES use for supplier selection and supplier governance, identify sourcing professionals’ work process interdependence as a moderator for the impacts of SES use on job satisfaction, and suggest job satisfaction mediates the impacts of SES use on job performance. We conducted a field study of sourcing professionals’ SES use at one of the largest consumer product companies in the United States, which has implemented an SES to innovate its sourcing professionals’ work processes. Based on our analysis of the survey and qualitative data we collected, we found the impacts of both types of SES use (1) to be negative on job satisfaction when work process interdependence was high, (2) to be positive on job satisfaction when work process interdependence was low, and (3) to be mediated by job satisfaction for job performance. We discuss the implications of our findings for the literature at the intersection of information systems and operations management as well as for the information technology enabled innovation of sourcing processes and, more generally, complex business processes.  相似文献

This article maps some of the ways that the critique of tourism development in the Indian state of Goa is connected to Goan patriotism. Reactions against tourism in Goa assume a prior definition of 'Goa', and this definition is often patriotic. One of the central processes to understanding contemporary Goa's identity politics in the face of tourism is its former colonisation by the Portuguese. Treating the tourism critique in Goa as a geographically and historically specific discourse in this article means discussing four aspects of what will be called its spatiality: geopolitics, geohistories/disembeddings, socio-spatial biases and situatedness. It will be argued that the spatiality of the tourism critique shows that its connection to patriotism is not straightforward and immediate, but contingent. It will also be argued that although the spatiality of the tourism critique points to its heterogeneity, it is precisely because there are multiple constructions of 'Goa' and 'Goan identity' that the discourse constitutes its object, Goa.  相似文献

China is rapidly becoming an important market for consumer goods, but relatively little is known about variations in consumer shopping patterns in different regions of China. We employ a cultural materialism perspective in understanding decision-making styles of inland and coastal shoppers. Our findings reveal that consumers in the two regional markets do not differ in utilitarian shopping styles but they do in hedonic shopping styles. Marketers need to understand these differences to be able to market effectively to consumers in different regional markets within China.  相似文献

Multiple categories of retail products suffer limited shelf life, demand uncertainty, and, in some cases, long lead times. To provide retailers with an incentive to increase the stocking quantity of such products, manufacturers may offer an option to return unsold items at wholesale or less than wholesale prices. This article extends the additive price-dependent demand model in three ways. First, partial returns are optimal for the manufacturer but do not induce higher stocking quantities compared with when the manufacturer offers no returns. Second, in terms of the effect of investment in demand-enhancing activities, when retailers invest, they set higher resale prices, but an optimal partial returns policy still does not induce higher stocking quantity, whereas when manufacturers invest, the optimal returns policy induces higher stocking quantity. Third, when the manufacturer and retailer have different expectations of demand uncertainty, the retailer's estimate influences the expected profits for both, whereas the manufacturer's estimate has a major impact on its profits only.  相似文献

This study attempts to identify differences in the perceptions of top management (defined as CEOs, directors, and presidents) and employees (defined as middle and supervisory management) regarding (a) the effects of dependent care responsibilities on job performance, and (b) the extent of a firm's responsibility in providing support for those faced with caring needs concerning eldercare, childcare, substance abuse, and mental/physical handicaps. The results indicate that these two groups have significantly different perceptions of the effect of dependent care responsibilities on job performance, and on the firm's responsibility in providing support for three types of dependent care.  相似文献
