ABSTRACT

This 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

A bivariate probit model was employed to jointly and separately estimate banana market participation decisions of buying and selling households in Rwanda and Burundi using household survey data. Selectivity bias was corrected for estimating the transacted volumes using Heckman's procedure. The results showed that transaction cost‐related factors such as geographical location of households, market information sources, and travel time to the nearest urban center influence market participation. Non‐price‐related factors such as security of land tenure, labor availability, off‐farm income, gender of the household head, and years of farming experience had a significant influence on the transacted volumes. Output prices had a significant correlation with sales volume, indicating price incentives increased supply by sellers. Generally, the findings suggest that policies aimed at investments in rural road infrastructure, market information systems, collective marketing, and value addition of banana products may provide a potential avenue for mitigating transaction costs and enhancing market participation and production of marketed surplus by rural households.  相似文献

The purpose of this paper is to present a new approach to econometric modeling of substitution and technical change. Substitution is determined by observable variables, such as prices of output and inputs and shares of inputs in the value of output. Our principal innovation is to represent the rate and biases of technical change by unobservable or latent variables. This representation is considerably more flexible than the constant time trends employed in the previous literature. An added advantage of the new representation is that the latent variables can be projected into the future, so that the rate and bias of technical change can be incorporated into econometric projections.  相似文献

The authors study abnormal returns and volume in the days surrounding takeover speculation by financial media. Significantly positive price and volume responses 2 days after publication are observed. While most of this effect dissipates shortly thereafter, some excess returns remain impounded into the stock price. A study of the ex post takeover probabilities suggests that a positive response is justified, as takeover probabilities for such firms subsequently increase. This evidence is consistent with the idea that financial media speculation can facilitate the release of useful private information to shareholders. However, significantly positive excess returns and volume in the few days before publication also suggests that certain shareholders may benefit disproportionately.  相似文献

Measures of multifactor productivity growth in natural resource industries are misleading without accounting for the effects on the environment. This paper introduces environmental effects into an output-oriented Malmquist index of multifactor productivity growth in order to evaluate growth in productivity and technical efficiency for Korean purse seine vessels fishing for tuna in the Western and Central Pacific Ocean.  相似文献

Tourism is a key driver of global socio-economic progress. However, its sustainability is at risk from multiple shocks and hazards that threaten livelihoods. Surprisingly little is known about the complex drivers of destination vulnerability, leading to the creation and application of ineffective resilience-building solutions. The paper presents the Destination Sustainability Framework (DSF) designed to assess destination vulnerability and resilience, and support successful resilience-building initiatives. Holistic in nature, the DSF comprises: (1) the shock(s) or stressor(s); (2) the interconnected dimensions of vulnerability – exposure, sensitivity, and system adaptiveness; (3) the dynamic feedback loops that express the multiple outcomes of actions taken (or not); (4) the contextualised root causes that shape destinations and their characteristics; (5) the various spatial scales; and (6) multiple timeframes within which social-ecological change occurs. This innovative framework is significant because it's the first framework to chart the complex manifestation of vulnerability and resilience in tourism destinations. Further, it brings tourism sustainability research in line with wider debates on achieving sustainability within the dynamic coupled human–environment system, doing so through the inclusion of insights from contemporary systems approaches, including chaos–complexity theory, vulnerability approaches, sustainability science, resilience thinking, along with the geographies of scale, place and time.  相似文献

Food justice, food cultures and people's engagement with healthy food production and consumption are key contemporary concerns, with a growing sustainable hospitality and tourism literature. Efforts range from narrowly focused initiatives, such as promoting organic produce and fair trade, to more holistic challenges to current systems through initiatives like the slow food and locavore movements, which may represent systemic alternatives. However, little analysis is available on how cafés and restaurants might become sites for experimentation in profitable and just sustainable hospitality, and places for sustainability engagement and education. Focusing on the evolution of a sustainable café in Adelaide, South Australia, this article explores how one entrepreneurial restaurateur uses his café to engage customers and community in a collaborative conversation about sustainable development, food, hospitality and tourism, helping transform our food culture and even lifeways. Our findings indicate the value of deep local embedding as a pathway to meaningful sustainability. The study offers insights into how hospitality and tourism can contribute to dialogues on alternative consumption which may offer visionary pathways to alternative futures. It also explores the role of pioneers in sustainable business and hospitality, their drivers and their views. A forthcoming global research initiative is discussed.  相似文献

Samoa and its neighbouring Pacific Island Countries are highly vulnerable to climate change risks because their population and infrastructure are mostly located on low-lying coastal areas. Impacts of climate change are potentially disastrous to tourism, the major economic sector in the region. This research examines the conduciveness of the policy environment in Samoa for the tourism sector to adapt to climate change along three dimensions: stakeholders’ will and commitment, resources available, and policy-making mechanisms [Wong, E.P.Y., Mistilis, N., & Dwyer, L. (2011). A framework for analyzing intergovernmental collaboration – the case of ASEAN tourism. Tourism Management, 32, 367–376]. Samoa is used as an exemplar case study to understand how the Pacific island tourism sector can best adapt to climate change. It was found that the policy environment in Samoa is generally conducive. However, there is a strong need for closer public–private cooperation.  相似文献
