The impact of biofuels on food prices, lessons from the experiences of Brazil and U.S. (1995-2013)Ncube, Free P January 2015 (has links)
Using crops for fuel generates concerns over competition with food uses. As Rajagopal et al (2009) asserts, “In 2008 the world entered a food crisis amid record-high commodity and energy prices that induced hunger and political unrest in developing countries, by export restrictions in top grain-producing countries”. This took place at the same time when biofuel production, reached its pinnacle in developed countries. This paper examines the effect that biofuel prices and or production has had on food prices in Brazil and U.S. by employing the panel cointegration and Dynamic Ordinary Least Squares (DOLS) method of analysis. In regressing food prices as a function of demand and supply factors, such as oil prices, biofuel prices, interest rates and biofuel production, the study found that the increase in biofuels production over the past eighteen years has had a significant impact on food prices. Over the period January 1995- December 2013, the study estimates that a one hundred percent increase in biofuels production across time and between countries results in the increase of food prices by 21,9%. The study therefore rejects the null hypothesis that states, biofuel production does not have a statistically significant negative impact on food prices in U.S. and Brazil. , and accepts the alternative that biofuel production does have a statistically significant negative impact on food prices in U.S. and Brazil. Other predictors of food prices that the study revealed as significant were oil and interest rates. Policy recommendations for other countries like South Africa are therefore, made based on the results obtained.

Food Prices, Income and the Optimal Control of WeightYan, Guo-hao 12 July 2012 (has links)
The thesis studies determinants and adjustment paths of the people's weight from the view point of rational behavior.It followes the research approach of Becker and Murphy (1988), makes use of the utility function from Levy (2002), and corporates a budget constraint so as to establish an optimal control model for food consumption and weight, and to find out the relationship between them.
Negative correlations are found between the steady-state weight and food prices, basal metabolic rate, and time discount rate.Positive correlations are found between the steady-state weight and income, marginal utility of food, and desirable weight. There is a tendancy to guide the actual steady-state weight to a much higher fluctuation margin than that of the desirable weight.In the dynamic analysis, it is also found that, regardless of an increase or decrease of the steady-state weight, both directions of adjustment show that the process of food consumption is always ``overshooting."In other words, when the steady-state weight becomes heavier (lighter), consumers first increase (decrease) their food consumption substantially. And, as the time goes by, there is a gradual decrease (increase) in food consumption owing to the fact that the food consumption is still higher (lower) than what is required for metabolism of the body that makes the weight getting to increase (decrease) till the new equilibrium is arrived.

UNDERSTANDING THE LINK BETWEEN ETHANOL PRODUCTION AND FOOD PRICESMonteiro, Nathalia Ferreira 01 January 2009 (has links)
Food prices have increased rapidly in recent years, and so has ethanol consumption. Some studies have claimed that there is a connection between those two. Net exporters of food tend to benefit from higher prices, while regions that are net importers of food, tend to be adversely affected. The large amount of poor countries in the second group justifies an investigation of the causes of increasing food prices. This thesis aims to contribute to the discussion, analyzing, theoretically and empirically, the impact that the diversion of feedstock from food to ethanol production has on food prices. The interaction between food prices and ethanol is first examined in a two-good (food and ethanol), one input (land) theoretical model. The outcome of this model is that an increase in ethanol productivity will have a positive impact on food prices, which is confirmed in the empirical test. We also found that increases in area allocated to produce sugarcane based ethanol in Brazil had depressing effects on relative food prices. No significant conclusion could be found on the effect of the area allocated to produce corn based ethanol in the United States.

La sécurisation alimentaire des pays d'Afrique sub-saharienne par la maîtrise de l'instabilité des prix des matières premières agricoles : une perspective économétrique. / The Reinforcement of the state of food security of African Sub-Saharan countries through the management of the instability of agricultural food commodities prices : an econometric prospectDiallo, Abdoul Salam 11 December 2013 (has links)
Nous soutenons la thèse que la sécurité alimentaire des pays d'Afrique sub-saharienne peut être renforcée par une meilleure maitrise de l'instabilité des prix des matières premières agricoles constituant leur panier alimentaire de base. A cet effet, nous évoquons dans un premier temps les mécanismes de fonctionnement des marchés agricoles, le rôle qu'y joue la notion de prix ainsi que le lien existant entre l'évolution instable des prix et l'insécurité alimentaire. Nous nous intéressons ensuite au lien existant entre l'insécurité alimentaire et la régulation du secteur agricole, en particulier dans le cadre des échanges internationaux et régionaux. Nous procédons enfin au traitement formalisé de l'insécurité alimentaire. En ayant recours aux outils économétriques, nous mettons en évidence le caractère instable des prix au niveau individuel des pays ainsi que les interdépendances entre les prix des différentes denrées alimentaires et des différents pays. Des mesures de sécurisation alimentaire sont suggérées tout au long de la thèse pour les pays d'Afrique sub-saharienne étudiés. Nous estimons que ces mesures peuvent servir de pistes de réflexion pour l'établissement de politiques économiques agricoles nationales et régionales. Ces politiques auraient pour but final de garantir la sécurité alimentaire des populations des pays de l'Afrique sub-saharienne par une meilleure maitrise de l'instabilité des prix alimentaires. / In our thesis, we assume that African Sub-saharan countries' food security status can be enhanced through a better management of agricultural commodities prices instability, which constitutes the basic food basket of local populations. To this aim, we initially review the dynamics of agricultural markets and the role played by “prices” in this mechanism as well as the existing linkages between unstable price trends and the notion of food insecurity. Focus is then directed to the relationship between “food insecurity” and the regulation of the agricultural sector, in particular within international trade theory frameworks.Finally, we proceed to the assessment of “food insecurity” through the empirical analysis of the instabilities affecting food prices of the region, and also that of price transmission and linkages within and between countries. We then highlight prices instabilities at individual (country) level, as well as the linkage of these prices (therefore of their unstable components) between the various constituents of the basic food basket of a given country, or that of neighboring countries.All along our thesis, food insecurity resilience measures for these countries are suggested. These measures are believed to potentially serve as initial steps in the establishment of national and regional agricultural policies aiming at attaining/safeguarding food security in African sub-Saharan countries.

Comparative study of purchasing power parities for the food component using the consumer price index data in the South African provincesKgantsi, Eugene Modisa 22 April 2013 (has links)
A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science, 2012. / The purpose of this study is to investigate if the International Comparison Program (ICP) methodology could be used to examine the different buying power (worth) of the currency on the same products or goods amongst South African provinces. The method will be tested on the Consumer Price Index (CPI) food data collected from January 2006 to December 2006 from the main cities in the provinces. The food basket is obtained via the Income and Expenditure Survey (IES), which is generally updated every 5 years.
South Africa (SA) has disparities and differentials in economic indicators such as the CPI, Gross Domestic Product and employment, amongst the provinces which are caused by among other things geographic set-up, urbanisation, inflation rates, and expenditure patterns. We use the monthly data to do an inter-provincial comparison of food prices by deriving annual purchasing power parities (PPPs) for each of the provinces, using the Country Product Dummy (CPD) method recommended as best practice by the World Bank.
The CPI data is validated using the SEMPER software developed by the African Development Bank (AfDB). The validated data is examined for variability over the months and between the provinces using Analysis of Variance. Significant price differences are found for various products over the months and between provinces. The validated data was used to compute PPPs at the group and basic heading level. PPPs were investigated for differences in the provinces on grouped level of food products using Analysis of Variance. The reliability of PPPs between provinces is investigated both at grouped and basic heading level of products using the Cronbach-alpha statistic.
The results show that there are no significant variations in PPPs across provinces. This could be due to the similar business opportunities or developments in the provinces or due to the aggregation of prices from the individual product (basic heading) to the main product group level. This implies that the cost of the food basket is the same across provinces.
