摘要

海地是一个独特的大米市场,尽管贫困率高且依赖大米作为主食,但它依赖进口(占总消费量的80%)优质精米,并支付溢价。海地要求所有进口大米的碎粒率不得超过4%,这导致海地进口了世界上最昂贵的无香长粒大米之一。本研究实施了一个非假设的实地实验(300个观察值),以引出海地人在露天市场环境中的购买行为所揭示的大米属性。具体来说,我们开始估计海地人是否会对碎米打折,从而使严格的进口规定继续得到保证,这些规定将更便宜的进口碎米排除在国内市场之外。我们的研究结果表明,除了收入最高的群体外,消费者(不同地区和收入群体)并没有为减少的碎米支付更多的钱。这应该向海地的决策者发出信号,表明消费者愿意消费破碎率高于4%进口标准的大米。从粮食安全的角度来看,这一点很重要,因为破碎率较高的大米与破碎率较低的大米具有相同的营养价值,并且可以以折扣价在全球采购。允许进口破损率较高的大米可以为相对昂贵的国产大米和进口大米提供更便宜的替代品,从而有助于缓解海地的粮食不安全状况。目前,由于海地进口商强加的高质量标准,国产大米和进口大米价格过高。

A broken market: can increased access to broken rice decrease food insecurity in Haiti?

Haiti is a unique rice market in the sense that, despite the high poverty rates and dependency on rice as a staple, it relies on imports (80% of total consumption) of high-quality milled rice for which it pays a premium price. Haiti requires that all imported rice have a maximum of 4% broken kernels, which results in Haiti importing one of the most expensive non-fragrant long grain rice in the world. This study implements a non-hypothetical field experiment (300 observations) to elicit which rice attributes Haitians valued as revealed by their purchasing behavior in an open-air market setting. Specifically, we set out to estimate if Haitians would discount broken rice in such a manner that strict import regulations, which keeps cheaper imported broken rice out of domestic markets, continue to be warranted. Our findings suggest consumers (across locations and income groups) were not found to pay more for a reduced amount of broken rice, with the exception of the highest income group. This should signal to policy makers in Haiti that consumers are willing to consume rice with a higher percentage of brokens than the 4% importation standard. This is important from a food security standpoint as rice with a higher broken percentage provides the same nutritional value as rice with a lower broken rate, and can be sourced globally at a discounted price. Allowing imports of rice with higher broken rate could help alleviate food insecurity in Haiti by providing a cheaper alternative to relatively expensive domestic rice and imported rice, which currently has an inflated price due to its high-quality standards imposed by Haitian importers.

期刊介绍: Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
