Social Marketing of a Fortified Staple Food at Scale: Generating Demand for Fortified Rice in Brazil
Peiman Milani Emily Carnahan Seema Kapoor Corwyn Ellison Caroline Manus Rebecca Spohrer 《食品市场学杂志》2017,23(8):955-978
ABSTRACTThis paper describes the social marketing strategy implemented by PATH and GAIN to create a sustainable market for rice fortification in Brazil and develop a replicable model relevant to other geographies. It draws on market research on consumer attitudes and practices, as well as key demand and consumer metrics before and after execution of the social marketing campaign in Brazil. This marketing endeavor succeeded in establishing the viability of introducing fortified rice in a country through a purely market-based approach. Whereas social marketing is vital to the introduction and scale-up of fortified staple foods through commercial markets, it is not sufficient to achieve meaningful scale and sustainability. Engagement from the public and social sectors, clear governance, and other factors are critical to substantial and long-term impact. Lessons from this first attempt to introduce a fortified staple food through a market-based approach are relevant to similar initiatives elsewhere. 相似文献

The success of an innovating firm often depends on the efforts of other innovators in its environment. How do the challenges faced by external innovators affect the focal firm's outcomes? To address this question we first characterize the external environment according to the structure of interdependence. We follow the flow of inputs and outputs in the ecosystem to distinguish between upstream components that are bundled by the focal firm, and downstream complements that are bundled by the firm's customers. We hypothesize that the effects of external innovation challenges depend not only on their magnitude, but also on their location in the ecosystem relative to the focal firm. We identify a key asymmetry that results from the location of challenges relative to a focal firm—greater upstream innovation challenges in components enhance the benefits that accrue to technology leaders, while greater downstream innovation challenges in complements erode these benefits. We further propose that the effectiveness of vertical integration as a strategy to manage ecosystem interdependence increases over the course of the technology life cycle. We explore these arguments in the context of the global semiconductor lithography equipment industry from its emergence in 1962 to 2005 across nine distinct technology generations. We find strong empirical support for our framework. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The aim of this paper is to examine the impact of US macroeconomic conditions—namely, exchange rate and short-term interest rate—on the stock markets of seven Asian countries (China, India, the Philippines, Malaysia, Singapore, Thailand, and South Korea). We use daily data for the period 2000–2010. We divide the sample into a pre-crisis period (pre-August 2007) and a crisis period (post-August 2007). We find that, in the short-run, the interest rate has a statistically insignificant effect on returns for all countries, except for the Philippines in the crisis period. On the other hand, except for China, regardless of the crisis, depreciation has a statistically significant and negative effect on returns. When the long-run relationship among the variables is considered, for five of the seven countries (India, Malaysia, the Philippines, Singapore, and Thailand), while there is cointegration in the pre-crisis period, in the crisis period there is no such relationship, implying that the financial crisis has actually weakened the link between stock prices and economic fundamentals. 相似文献

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries 总被引:4,自引:0,他引:4

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem. 相似文献

This research uses neighborhood characteristics (at the zip code level) in 1990 to explain toxic releases in 1993. It combines the Toxics Release Inventory data with demographic data from the 1990 U.S. Census. We first analyze the location of manufacturing facilities in a particular neighborhood using a sample selection model, and then estimate the relationship between releases in 1993 and the demographic characteristics of the neighborhood in 1990. We conduct the analysis for the entire U.S. as well as for different geographic regions to study regional differences in determinants of environmental outcomes. Releases in nonurban areas of the southeastern U.S. exhibit a pattern suggesting that race might be an important determinant of release patterns. Economic characteristics of neighborhoods (such as income levels and unemployment) also affect releases. Our variables that proxy the propensity for communities to engage in political action exert greater influence on environmental outcomes in nonurban areas. 相似文献

While India is among the world's largest producers and exporters of apparel products, the sector has not performed to its potential. This study analyzes why this might be so from the perspective of the structure of production in the sector, the most striking aspect of which is a firm size distribution heavily dominated by small firms. Using nationally representative firm‐level and labor force survey data, we argue that the dominance of firms operating at scales too small to apply modern production and management technologies is one proximate reason for India's relative underperformance. Further, we note that India's labor regulations and the associated enforcement regime are important policy drivers of Indian firms' tendency to avoid placing “too many workers under one roof”. 相似文献

In this article we examine several hypotheses relating to output and inflation dynamics in China. The hypotheses tests are based on the exponential generalised autoregressive conditional heteroskedasticity (EGARCH) model of Nelson [Nelson, D. (1991). Conditional heteroskedasticity in asset return: A new approach, Econometrica, 59, 347–370]. Our findings suggest that Chinese output–inflation behaviour is consistent with the hypothesis that increased inflation uncertainty lowers average inflation; the hypothesis that inflation volatility reduces economic growth and the hypothesis that higher output volatility increases economic growth. However, we find no support for the hypothesis that higher output volatility increases the average inflation rate. 相似文献

It is well documented that if environmental degradation is to be halted then pro-environmental activities need to be put in place now. This requires the participation of consumers (C), marketers (M) and policy-makers (in this case, the local council (LC)). An examination of the environmental portfolios of LCs and Ms indicates a noticeable increase in behavioural activity which has led to an improvement in their environmental provision. This includes services ranging from recycling to providing information on environmental issues. However, empirical evidence indicates that consumers may have either inadequate or inappropriate knowledge about environmental issues which may have led to low involvement levels and consequently limited behaviour. It may therefore be necessary to distinguish between cognitions that are affected under high or low involvement situations. The involvement levels, however, may be mediated by the consumer behaviour settings (CBS). Using the Behavioural Perspective Model the study observes the impact of CBS and involvement on environmental behaviour. The results indicate that in the low involvement condition CBS has a crucial role to play whereas in the high involvement situation its role may not be significant. 相似文献

Abstract. In this paper, we analyse per capita income levels of China's three main regions: the western region, the eastern region and the central region using common cycle and common trend tests. Our main contribution is that we impose the common cycle and common trend restrictions in decomposing shocks into permanent and transitory components. We find that: (i) there is evidence for two cointegrating relationships and one common cycle; and (ii) the variance decomposition analysis of shocks provides evidence that over short horizons, permanent shocks play a large role in explaining variations in regional per capita incomes. 相似文献

Why do some new technologies emerge and quickly supplant incumbent technologies while others take years or decades to take off? We explore this question by presenting a framework that considers both the focal competing technologies as well as the ecosystems in which they are embedded. Within our framework, each episode of technology transition is characterized by the ecosystem emergence challenge that confronts the new technology and the ecosystem extension opportunity that is available to the old technology. We identify four qualitatively distinct regimes with clear predictions for the pace of substitution. Evidence from 10 episodes of technology transitions in the semiconductor lithography equipment industry from 1972 to 2009 offers strong support for our framework. We discuss the implication of our approach for firm strategy. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
