  • What's Driving Food Prices in 2011?
    What’s Driving Food Prices in 2011? .YP] Preface ree years ago Farm Foundation, NFP asked Purdue University economists Wallace Tyner, Philip Abbot and Christopher Hurt to review the literature and provide a comprehensive assessment of the major factors driving commodity and food prices. Our objective was to cool the heated rhetoric in the food-versus-fuel debate, which had been rising right along with the prices of corn and oil. Today, although the rhetoric seems to be lower, prices of oil and commodities, including corn, soybeans and wheat, have again approached the levels of 2008. In addition, policy makers today are focused on a national debate over fiscal policy—a debate that encompasses the future direction of food, agricultural and energy policies. Farm Foundation commissioned the current paper to provide a comprehensive, objective assessment of the forces driving commodity and food prices. A major question was whether the forces at work today are the same as or different from those of 2008. Our goal is to provide public and private decision makers with an objective assessment of the forces driving commodity prices, as well as offer some insights into the impacts on policy options. Now, as in 2008, the full story behind rapid increases in commodity prices is not a simple one. Many of the factors driving prices remain the same but play out in different ways—including biofuel demands, exchange rates and weather. As concluded in 2008, one simple fact stands out: economic growth and rising human aspirations are putting ever greater pressure on the global resource base.

  • Food Price Variation
    2019 Food Price Variation The USDA estimates that 40 million people, including more than 12 million children, in the United States are food insecure as of 2017. This means that 1 in 8 individuals (13%) and 1 in 6 children (17%) live in households without 40 million consistent access to adequate food. The experience of food insecurity -or- depends on individual circumstances, local economies, and broader social and economic forces. Food prices in particular represent an important component of cost-of-living that affects households’ ability to afford food. 1/8 In fact, the high relative price of food contributed to the persistently high people are food insecure. rate of national food insecurity in the years following the Great Recession.1 Food prices began edging upward again in 2017 and 2018, and are expected to continue rising in 2019.2 For the ninth consecutive year, Feeding America has conducted the Map the 1,352 Meal Gap study to improve our understanding of how food insecurity and counties (43%) have food costs vary at the local level. This brief focuses on the variation in local meal costs higher than food prices and the average cost of a meal, one of four related topics that the national average. make up the Map the Meal Gap 2019 report briefs. Through the lens of local meal costs, it is possible to see how people already struggling with hunger in communities across the country can find it difficult to afford enough food to live active, healthy lives. $3.02 is the national average meal cost.

  • International Food Security Assessment, 2020-2030
    Summary United States Department of Agriculture A report summary from the Economic Research Service August 2020 United States Department of Agriculture Economic Research Service International Food Security International Food Security Assessment, Assessment, 2020–30 GFA-31 August 2020 2020–30 Felix Baquedano, Cheryl Christensen, Kayode Ajewole, Despite sharp income declines in 2020 due to the COVID-19 pandemic, food security outlook improves by 2030 for 76 low- and middle-income countries. and Jayson Beckman What Is the Issue? Income, food prices and economic inequality are major factors determining how much access people have to food. Agricultural production and market conditions affect how much food is available. Widespread food availability, rising income levels, and low food prices improve a country’s food security, although the breadth of these gains can depend on the distribution of income within a country. Conversely, disruptions to income, prices, or food supply can increase food insecurity, especially for the poor. Understanding how these factors collectively influ- ence food demand provides a measure of progress in assessing food security. This report looks at these factors to assess current-year levels of food security and to project changes in food security over the next decade for 76 low- and middle-income countries in Sub-Saharan and North Africa, and in Latin America and Asia. The report provides information for USDA and its stakeholders to estimate long-term projections of food security in these countries. It also analyzes the impact of an income shock associated with the COVID-19 pandemic on present and future food security. What Did the Study Find? Given the rapidly evolving situation at the country level and the uncertainty of estimates of economic shocks from the COVID-19 pandemic at the country and global levels, the results presented in this report are representative of a baseline scenario based on macroeconomic trends up to April 2020, consumption and production data up to January 2020, and price trends over the period 2017–2019.

  • The Global Food Price Crisis: Lessons and Ideas for Relief Planners and Managers
    The Global Food Price Crisis: Lessons and Ideas for Relief Planners and Managers The first half of 2008 was marked by significant rises in commodity prices, with food price increases averaging 52 percent between 2007 and 2008. While the response to the wider situation is largely outside the scope of humanitarian programmes, those managing relief and recovery efforts have faced a number of challenges. This paper lays out the background to the food price rises, outlines a number of key challenges for those planning and managing relief efforts, and suggests ideas, tools and approaches that could prove of value.

  • Rising Food Prices: Cause for Concern Steve Wiggins and Stephanie Levy
    Natural Resource Perspectives 115 June 2008 Overseas Development Institute Rising food prices: Cause for concern Steve Wiggins and Stephanie Levy he current spike in food prices needs prompt reaction through various forms of social protection to avert poverty and hunger. Prices are soon likely to fall somewhat, but not to their previous levels. Higher prices mean problems for three groups: poor households struggling to cope with higher costs of food; governments of low income food-importing Tcountries facing higher import bills and higher energy prices; and agencies such as the World Food Programme (WFP) that use food aid to combat food emergencies. Policy conclusions • Food prices have been rising since the early 2000s but spiked in early 2008. Even if they start to decline later this year, the next ten years will see food prices at levels above those seen in the early 2000s, thanks to higher energy costs, demand for biofuels, growing demands for staples as populations grow, and for higher value foods, such as livestock products, as incomes rise. • Prompt assistance is needed for countries facing surging food and energy import bills and for low-income households • Low stocks threaten the functioning of agencies such as the WFP and prompt calls for land to be switched back into food production, from biofuels throughout the OECD, and from “set-aside” in the EU. • In the medium term, economic and agricultural growth can offset the damage, but this will require more determined efforts to boost food production. • Beyond action, a better understanding is needed of the 2008 price spike, to ensure that such events are rare.

  • Chapter IV the Global Food Crises
    Chapter IV The global food crises When the global financial and economic crisis hit, a large number of developing countries were still reeling from the economic and social impacts of the earlier global food crisis. In 2008, the cereal price index reached a peak 2.8 times higher than in 2000; as of July 2010, it remained 1.9 times higher than in 2000 (Food and Agriculture Organization of the United Nations, 2010a; 2010b). Prior to the global financial crisis, concerns about the spikes in food and energy prices were at the centre of public and media attention. Global leaders and policymakers were concerned about the potential welfare impacts of the sharp increases in the prices of food commodities, such as rice, corn (maize), wheat and soybeans, as well as global food security. There was concern about how higher food prices were adversely affecting low-income consumers and efforts to reduce poverty, as well as the political and social stability of poor countries and food-importing countries. These concerns have subsequently heightened with the social tensions, unrest and food riots that have broken out in several countries. However, attention to the fragile and unsustainable global food security situation was pushed off the centre stage of international concerns and replaced by the global financial and economic crisis and the later push towards budget cuts and fiscal austerity in most major industrialized countries. Unfortunately, the food crisis is still far from over as prices have been rising once again since 2009 (Johnston and Bargawi, 2010). The poor remain especially vulnerable, as the Food and Agriculture Organization (FAO) has warned repeatedly.

  • Determinants of Food Price Inflation in Ethiopia
    Food Science and Quality Management www.iiste.org ISSN 2224-6088 (Paper) ISSN 2225-0557 (Online) Vol.41, 2015 Determinants of Food Price Inflation in Ethiopia Zewdu Hilegebrial Research Officer in the National Bank of Ethiopia. Abstract This paper explores determinants of food price inflation in Ethiopia during 1971-2013. Based on empirical and theoretical literature, the OLS estimate contain the dependent variable which is Food price inflation as a function of major explanatory variable i.e. money supply, Real GDP, Inflation expectation and world food price. The empirical result reveals that Food price in Ethiopia is determined both demand (money supply and expectation) and supply (output and world food price) factor. The short run dynamic error correction equation depicts that all the variables except money supply are statistically significant at 5% level in the model and they have expected sign. The finding also revealed that the adjustment coefficient for the estimated food price equation is statistically significant at 1% level and negative. It is incredibly fine with about 97 percent convergence of the short-run shock existing last year towards its long-run path in the current year. I Introduction Price stability is one of the principal economic goals in any economy. It is desirable that the overall price level for goods and services remain relatively stable. Price stability is always one of the common objectives of economic integration policies and has been a strategic one for monetary policy of the West African Monetary Zone (Tucker, 2003). Inflationary pressures are known for its negative impact on social welfare and disable the domestic economy from performing efficiently (Fullerton, et al 1997).

CENTRE D’ETUDES ET DE RECHERCHE EN DEVELOPPEMENT INTERNATIONAL CNRS – UNIVERSITE D’AUVERGNE Introduction Price and food insecurity: a complex relationship An illustration from Niger Conclusion • Since 2008, food prices have attracted much attention. High food prices are generally considered as a threat to food security. • But high food prices is neither a necessary nor a sufficient condition for food insecurity. • And prices do not necessarily reflect food availability • Need for disaggregated approaches and strengthening market’s institutions Introduction The entitlement approach to hunger Price and food insecurity: a complex relationship High food prices are not a sufficient condition for food insecurity An illustration from Niger High food prices are not a necessary condition for food insecurity conclusion Food prices may not reflect food scarcity The entitlement approach of hunger • According to Sen’s entitlement approach to hunger, famine can occur without any decline in food supply and food price increase. • A sufficient condition for famine is a decline in food entitlements which itself results from a worsening in the endowment set and/or the entitlement mapping of a group of people • The entitlement set of a person is the commodity bundles she can legally acquire from her initial endowment through trade, production and transfer i.e.

  • Developments in Global Food Prices
    Developments in Global Food Prices Vanessa Rayner, Emily Laing and Jamie Hall* Global food prices have increased significantly since the early 2000s, reversing the long-run trend decline in relative food prices over previous decades. A range of supply disruptions in key food-producing countries have contributed to higher food prices, along with strong demand from developing countries as per capita incomes rise and consumption patterns change. Rising commodity prices are leading to higher headline consumer price inflation in many countries though, at this stage, core measures of inflation remain relatively contained. Introduction prices on consumer price inflation tends to be greater in developing countries, where food makes The international prices of many agricultural up a larger share of households’ consumption commodities have increased significantly over basket. Some countries have taken direct measures the past two years. After falling sharply during the to contain domestic food price inflation and increase global financial crisis, the IMF Food Price Index has food supply, including imposing trade restrictions increased by 50 per cent since the end of 2008 and and penalties for speculation and hoarding, is now above its earlier peak in mid 2008. Supply increasing the supply of fertiliser, and improving disruptions have been an important factor behind supply-chain logistics. This article discusses the the recent rise in the relative price of food, with demand and supply factors underpinning the unfavourable weather conditions in a number of key recent rise in global food prices and implications for food-producing countries weighing on production inflation. – particularly for crops such as wheat, sugar, corn and soybeans.

  • Agricultural Markets and Prices: Towards 2025
    Agricultural Markets and Prices: Towards 2025 Highlights • Recent years have been marked by price spikes and considerable volatility; currently, some agricultural markets are experiencing sharp falls in prices. • Food and agricultural prices are expected to decline modestly in real terms in the next decade, but should generally remain higher than they were in the early 2000s. • The use of crops for biofuels has been largely policy-driven. A phasing-out of government support would contribute to lower and more stable food prices. What’s the issue? The situation of world agricultural markets is currently Over the next ten years, the biggest market changes very different from when agriculture ministers last met in will occur in developing countries. On the demand side, 2010.

This paper compares and contrasts these dynamic patterns between markets from the perspective of price bubbles. A newly developed right-tailed unit root testing procedure is applied to detect price bubbles in the CBOT and Chinese agricultural futures market during the period 2005-2014. Results show that Chinese markets experienced less prominent speculative bubbles than the international markets for its high self-sufficiency commodities (wheat and corn), but not for low self-sufficiency commodities (soybean). The difference in price behavior is attributed to differences in market intelligence, and to Chinese agricultural policies related to trade as well as domestic government policies. Besides, it discusses challenges to the sustainability of the stable price trajectory in Chinese markets.
