Reconsiderando la metodología FAO sobre el cálculo del número de personas que pasan hambre en el mundo AgEcon
Morales-Opazo, Cristian; Barreiro-Hurlé, Jesús.
FAO measure of undernourishment is calculated based on three main parameters: dietary energy supply (DES), minimum dietary energy requirement (MDER), and the coefficient of variation of dietary energy consumption (CV). In the current implementation of this methodology, the DES and the MDER change over time, as would be expected. The CV, however, remains constant. However, we expect the CV to change over time and be a function of income and prices. This paper discusses why the CV should change in response to changes in these variables, and suggests a practical way to estimate changes in the CV over time in the absence of survey data.

USEFULNESS OF PLACEMENT-WEIGHT DATA IN FORECASTING FED CATTLE MARKETINGS AND PRICES AgEcon
Norwood, F. Bailey; Schroeder, Ted C..
In 1996, the USDA began reporting cattle-on-feed placements in various weight groups, which should provide information regarding expected slaughter timings and improve fed cattle price forecasts and marketing strategies. Private data were collected to obtain the necessary degrees of freedom to test statistical relationships between placement weight distributions, beef supply, and fed cattle prices. Use of placement weights improved beef supply forecasts only at a one-month horizon; it contributed nothing to price forecast accuracy or returns from selectively hedging.

Portfolio Choice with Uncertain Consumption Prices: a mean-variance approch AgEcon
Berck, Peter; Cecchetti, Stephen G..
This paper presents a mean-variance model of portfolio choice and asset pricing when the price of consumption goods as well as the return to assets is uncertain. The correlation of an assets return with purchases at expected prices is shown to reduce both the mean return and the variance of the return of an asset. A numerical approximation is computed to check the accuracy of the mean and variance approximation. Uncertainty of consumption prices is shown to result in long (or speculative) futures holding.

Market Prospects for Pulses in South Asia: International and Domestic Trade Supplementary Report of the Project: Market Prospects for Upland Crops Products and Policy Analysis in Selected Asian Countries (MPUPA) AgEcon
Kyi, Hla; Mruthyunjaya; Khan, Naseer Alam; Liyanapathirana, Rupasena; Bottema, J.W. Taco.
This study contains compilations of price trends, production trends and institutional issues in the international market for food legumes or pulses. In recent years substantial changes have taken place in the Asian pulse market. There are signs that the national markets have opened up for imports with the result by the mid 1990s that Australia and Myanmar have become the major inter-regional suppliers of pulses. Nevertheless, participation of other countries in the Asian pulse market is very wide and includes production centres in Latin America, North America, Western and Eastern Europe and Africa. The study also reveals that within the group of pulses there are substantial price differences between specific varieties and species. This indicates that...

CONSTRUÇÃO DE UM CALENDÁRIO DE COMERCIALIZAÇÃO DE PRODUTOS HORTIFRUTIGRANJEIROS NO ATACADO EM GOIÁS AgEcon
Machado, Andre Grossi; Figueiredo, Reginaldo Santana; Neto, Odilon Jose De Oliveira.
O presente trabalho tem como objetivo analisar o padrão de variação sazonal dos preços de hortifrutigranjeiros comercializados no atacado em Goiás, e com isso, subsidiar o processo de construção de um calendário de comercialização para o CEASA-GO. O conhecimento da variação sazonal de preços de hortifrutigranjeiros, que são produtos caracterizados por uma grande variabilidade no comportamento de preços e quantidade ofertada ao longo do ano, pode contribuir para evitar desperdícios de alimentos e danos financeiros ao produtor e consumidor, na medida em que facilita a programação da produção e do consumo. Para a determinação do padrão de variação sazonal, utilizou-se o método da média geométrica móvel centralizada. Para 44 produtos selecionados a análise...

Dynamic Effects of Grain and Energy Prices on the Catfish Feed and Farm Sectors AgEcon
Muhammad, Andrew; Zheng, Hualu.
This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their determinants was confirmed. Given the effect of corn and soybean meal prices on catfish feed prices, and catfish fish feed prices on farm prices, the long-run responsiveness of feed prices to a percentage increase in U.S. ethanol production is 0.325, and the responsiveness of catfish farm prices is 0.064. Although both feed and farm prices increase with ethanol production, the relatively small responsiveness of farm prices when compared with feed prices suggests that...

What is the structure of the coffee market: Can the real poor benefit from the coffee trade? AgEcon
Pokorna, Irena; Smutka, Lubos.
This article deals with the trade with coffee. The primary aim of the paper is to analyse the international coffee trade. Because coffee belongs to the cash crops we have focus on the production. We have analysed the structure of the trade concerning the green (not roasted) coffee, roasted coffee and coffee extracts, essences or concentrates. The analyses of production show enormous differences between developed and developing countries on the supply side. Dissimilarity appeared in the price system. Our results show that developing countries (especially least developed countries) cannot fully benefit from the international trade because they are placed just on the lowest level of the production vertical line. The results prove that there must exist strong...

CGPRT Crops in the Philippines: a Statistical Profile, 1990-1999 AgEcon
Chowdhury, Mohammad A.T.; Arif, Muhamad.
"CGPRT Crops in the Philippines: A Statistical Profile, 1990-1999" is the eighth in the series of the CGPRT Centre's publications providing specific and wide-ranging agricultural data focusing on coarse grains, pulses, roots and tuber (CGPRT) crops in Asia. An earlier series was published in January 1992 in collaboration with the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD) covering the period 1960-1990. In keeping pace with the previous publication, this updated volume covers eight crops: corn (maize), mungbean, soybean, groundnut, cassava, sweet potato, white potato and rice. Although not a CGPRT crop, rice is the most important crop in the Philippines in terms of area planted and production, hence...

Differences in Prices and Price Risk Across Alternative Marketing Arrangements Used in the Fed Cattle Industry AgEcon
Muth, Mary K.; Liu, Yanyan; Koontz, Stephen R.; Lawrence, John D..
Information on prices and price risk differences across marketing arrangements aids fed cattle producers in making choices about marketing methods. As part of the congressionally mandated Livestock and Meat Marketing Study, we investigated fed cattle price and price risk differences across marketing arrangements. The analysis uses data representing cattle purchased by 29 large beef packing plants from October 2002 through March 2005. Results indicate that marketing agreements offered the best tradeoff between price level and price risk. Forward contracts had the lowest average yet highly volatile prices. Auction barn prices were higher than other methods but also the most volatile.

PRICE PREMIUMS FROM A CERTIFIED FEEDER CALF PRECONDITIONING PROGRAM AgEcon
Ward, Clement E.; Lalman, David L..
Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers while adding value for feeder cattle buyers. However, questions remain regarding the marginal returns from marketing preconditioned calves exceeds the marginal costs for preconditioning. This paper reports estimates from two models to determine the premium paid by feeder cattle buyers for preconditioned calves in the Oklahoma Quality Beef Network (OQBN) program. One model assumes feeder calf characteristics are independent as most previous research. The other assumes interdependency between several characteristics that are affected by preconditioning. Data were from seven feeder calf sales in Oklahoma in 2001 and another seven sales in...

Variation in Staple Food Prices in Eastern and Southern Africa: Causes, Consequences and Policy Options AgEcon
AAMP Policy Briefing 1 January, 2010 This brief summarizes the policy implications of three thematic papers and seven country background papers prepared for the COMESA-ACTESA policy seminar on “Variations in staple food prices: Causes, consequences, and policy implications.” There is little controversy about the need for governments to support staple food markets with infrastructure, market information, agricultural research, and other public goods. However, many of the most costly agricultural programs in eastern and southern Africa involve raising food prices to protect farmers, lowering food prices to protect consumers, and reducing volatility in food prices through a variety of mechanisms including tariffs, export restrictions, public trading in staple...

Food security policy in a stochastic world AgEcon
Adelman, Irma; Berck, Peter.
Food security may be increased by variance-reducing strategies, by food aid, or by development strategies. This paper uses a Korea CGE model, subjected to random fluctuation in world-prices and domestic food productivity, to evaluate these policies. We find that poverty-reducing development strategies are the most effective food-security strategies.

INFRASTRUCTURE, MARKET ACCESS, AND AGRICULTURAL PRICES: EVIDENCE FROM MADAGASCAR AgEcon
Minten, Bart.
The effect of recent agricultural market reforms in many developing countries is often measured through tests for market integration by analyzing co-variation of food prices. However, market integration studies often fail to link the discovery of the lack of integration to causal factors. This analysis documents and relates price variation to structural determinants in the case of Madagascar. The spatial variability between communities is linked to the distance to a paved road, the quality of the road, access to soft infrastructure, and the level of competition between traders. Differences in seasonal variation are mainly related to the differential opportunity costs of capital in rice villages and to hard infrastructure in non-rice villages. Communities...

Eco-Labeling and the Price Premium AgEcon
Sedjo, Roger A.; Swallow, Stephen K..
International environmental and government organizations propose eco-labeling as a market incentive to cause industry to operate in an ecologically sustainable and biodiversity-friendly manner. A microeconomic analysis questions whether eco-labeling will cause producer profits in a competitive industry to decline, even under a voluntary system, and whether eco-labeling will necessarily generate different prices for labeled and unlabeled product. Using wood product as an example, results identify conditions that may exist when firms lose profits, even under a voluntary system, and where existing production constraints may lead to a single price, regardless of labeling.

Are Staple Foods Becoming More Expensive For Urban Consumers In Eastern And Southern Africa? Trends in Food Prices, Marketing Margins, and Wage Rates in Kenya, Malawi, Mozambique, and Zambia AgEcon
Mason, Nicole M.; Jayne, Thomas S.; Donovan, Cynthia; Chapoto, Antony.
The world food and financial crises threaten to undermine the real incomes of urban consumers in eastern and southern Africa. This study investigates patterns in staple food prices, wage rates, and marketing margins for urban consumers in Kenya, Malawi, Mozambique, and Zambia between 1993 and 2009. There is high correlation among wage rate series for various government and private sector categories. We find that average formal sector wages rose at a faster rate than retail maize meal and bread prices in urban Kenya and Zambia between the mid-1990s and 2007. Although the 2007/08 food price crisis partially reversed this trend, the quantities of staple foods affordable per daily wage in urban Kenya and Zambia during the 2008/09 marketing season were still...

Global Food Price Volatility and Spikes: An Overview of Costs, Causes, and Solutions AgEcon
von Braun, Joachim; Tadesse, Getaw.
Since the 2007–08 food crisis, many thoughtful analyses have addressed the causes and impacts of high and volatile international food prices and proposed solutions to the crisis. These studies have covered global as well as local food price dynamics and policy reactions. The food price problem is, however, far-reaching, and its impacts are wide and interrelated. The price formation mechanism has become highly complex and dynamic. Policy actions are politically and economically sensitive. This situation calls for continuous and comprehensive assessments of the problem to provide timely and evidence-based knowledge for policy makers. This paper reviews existing evidence and theories and presents new thoughts and insights from analyses to enlighten the course...
