Abstract:

This thesis is based on three papers examining Gulf Cooperation Council (GCC) financial markets. The member countries of the GCC are Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. These countries have transitioned from developing to frontier markets over the past ten years, but there is considerable debate about whether GCC economies are efficient or affected by shocks in oil and other commodity markets. The first paper (chapter 2) considers GCC stock market returns and examines how they are affected by oil price shocks using a bivariate VAR-GARCH(1,1) approach. The c

Abstract:

The upward movement in oil and food prices in the 2000s has triggered interest in the information transmission mechanism between the two markets. This research investigates the volatility spillover between oil, food, and agricultural raw material price indexes for the period January 1980 to April 2008. The results of the Cheung-Ng procedure show that variation in oil prices does not Granger cause the variance in food and agricultural raw material prices. However, there is bi-directional spillover between agricultural raw material and oil markets. Besides, it examines volatility spillover betwe

Abstract:

We use a dynamic specific-factors model in order to analyze how factor incomes, i.e. wages, interest rate and land rent, change when food prices rise. Special attention is given to the effects of food price shocks on wages. In the context of the theory, a food price shock affects factor incomes through labor and capital markets. The magnitude of the effect of a price shock is defined by labor shares of the productive sectors, saving allocation, elasticity of substitution in the agricultural sector and factor intensities. A rise in food prices is likely to have a significant positive effect on

Abstract:

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.

Abstract:

This thesis examines the relationship between food prices, oil prices, carbon emission prices, exchange rates and global risk perception. To obtain the effects of these variables on the food prices, Toda and Yamamoto procedure is employed for 5-day week daily time series covering the period February 27, 2008 and March 21, 2011. The empirical results indicate that only volatility index Granger causes food prices. Furthermore, according to results of generalized impulse response plots food prices respond to all variables in the short run.

Given the global food price spike experienced in 2007/8, the core question of this research is, ‘what was the impact of the rising food prices on household welfare in Zambia'? Taking an empirical approach and using micro-economic methods, four welfare outcomes are assessed: consumption, equality of income distribution, poverty and nutrition. The 2006 and 2010 cross-section household surveys - Living Conditions Monitoring Surveys (LCMS) - are primarily used to answer the question. The thesis first assesses the changes in consumption patterns across time, geographical locations and quintiles. Th

The main reasons for changes in processed food prices are expected to be changes in input costs and demand factors. Input costs consist of material, labour, capital and fuel cost.

Abstract:

The thesis aims to analyze the economic and environmental consequences of the regulation to mandatorily blend bio-components into the fuel and prove its inefficiency. The theoretical part summarizes in detail the reasons of introducing the regulation, including the legislative framework, and generational evolution of biofuels. The analytical part uses statistical analysis of time series and price and efficiency indices to evaluate the effectiveness of biofuels in relation to reducing greenhouse gas emissions. The impact of the introduction of biofuels on the economy is specified through fuel p

Abstract:

ABSTRACT This dissertation explores the associations between recent global crises in staple food prices and finance and the following aspects of life in two communities on the island of Roatàn, Islas de La Bahia (Bay Islands), Honduras: household livelihoods; food commoditization; dietary diversity; food security; and nutritional status. The aims of this study are: ) assess the geographic and economic source(s) of foods consumed by two different communities on Roatàn; b) discover how the most recent economic and food crises have affected foodways and nutrition on Roatàn; c) assess how these c

Abstract:

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

Abstract:

There is a growing body of evidence that Canadian consumers have concerns about the impact of agricultural production on the health of the environment and on society. This study investigates the preferences of rural and urban consumers in Quebec for food attributes that provide environmental, health, and social benefits. The choice modeling technique was employed to estimate the implicit prices of specific food attributes and willingness to pay (WTP) values for alternative food products. Results suggest t

Abstract:

Cette thèse développe un cadre méthodologique innovant destiné à la prévision des prix et des rendements agricoles à l'échelle mondiale, en s'appuyant exclusivement sur l'analyse de données satellitaires et l'utilisation d'algorithmes d'apprentissage automatique avancés. Alors que les modèles prévisionnels conventionnels reposent sur une combinaison de données météorologiques, d'analyses économétriques et de rapports agricoles — sources souvent affectées par des délais et des imprécisions — notre approche propose une alternative robuste et en temps réel.Notre méthodologie s'articule autour de

The aim is to draw attention to an inefficient allocation of resources and capital, which has resulted in rising food prices and the high number of hungry people in developing coutries, which European and U.S. subsidy policy does nt accumulate capital and invest in their production.

Aufbauend auf dem agrarökonomischen, dynamischen Optimierungsmodell MAgPIE, zeigen die hier vorgestellten Forschungsergebnisse, dass die Governance-Leistung einen bedeutenden Einfluss auf den technologischen Fortschritt und das Wachstum der Flächenproduktivität hat, insbesondere für in der Entwicklung begriffene Regionen wie Lateinamerika, Afrika südlich der Sahara, Südasien und Südostasien. Dies wirkt sich wiederum auf die Landnutzungsdynamik aus, einschließlich der Ausdehnung von Ackerflächen und der Entwaldung. Neben Umweltauswirkungen beeinflusst die Governance-Leistung auch Lebensmittelp

Objetivos: Estudar a influência que a renda das famílias e os preços dos alimentos exercem sobre a aquisição de alimentos mais saudáveis (frutas e hortaliças, F&H) e menos saudáveis (bebidas adoçadas, BA). Metodologia: Utilizaram-se dados sobre aquisição de alimentos coletados pela Pesquisa de Orçamentos Familiares (POF), realizada entre julho de 2002 e junho de 2003 pelo IBGE em uma amostra probabilística de 48.470 domicílios do país. A influência da renda familiar e do preço de frutas e hortaliças e de bebidas adoçadas sobre seu consumo foi estudada empregando-se técnicas de análise de regr
