Texto completoSo demand for biomass is increasing, access to these resources is further constrained by socio-economic, (geo-)political or climatic events that destabilize value chains. Bio-economy structure, bio-economy value chains can be vulnerable to supply to supply disruptions. It is therefore supply risks and their impact on environmental, social and economic on the environmental, social and economic performance (i.e. sustainability) of activities. For this purpose, various assessment methodologies assessment methodologies exist: Life Cycle Sustainability Analysis (LCSA) and raw materials criticality assessment. These are very often carried out within companies by different people, with different objectives and objectives and timeframes. What's more, they cannot be used and need to be adapted to assess the challenges of the bio-economy and bio-economy and green chemistry.This work aims to answer the question "How can the sustainability of products from the bio-economy be assessed in a context of variation in the availability and accessibility of renewable biomass resources?". By adopting the point of view of firms, this research studies the potential integration of life-cycle sustainability assessment and criticality assessment of lignocellulosic resources, whose demand is growing rapidly, notably with the emergence of biofuels. in particular with the emergence of biorefineries driven by the green chemistry the production and use of bio-sourced solvents. The latter are based on the transformation of bio-sourced platforms and aim to substitute petro-sourced solvents in order to the transition to a bio-economy. The question of substituting a lignocellulosic resource by another in the case of this thesis, is central to the is at the heart of these questions, since it is a common strategy for supply risks, although this decision may also have environmental, social and economic have negative environmental, social and economic impacts.The thesis proposes a criticality assessment method specific to the resources and commodities of the bio-economy, "LignoCrit". The development of LignoCrit, based in part on ADCV data and results ADCV, requires a common structure to integrate the two methods. Thus, ADCV was applied to the case of a bio-sourced solvent, 2-Methyl Tetrahydrofuran (2-MeTHF), demonstrating the preponderance of chemical transformation processes in the solvent's social and economic impacts of the solvent. However, the choice of lignocellulosic resource and the country of production, for solvent production has a significant effect on the results.Data and results of the different 2-MeTHF production scenarios evaluated in the ADCV are then injected into the criticality method on the basis of the data and results obtained. Thus, a score aggregating the various dimensions of the LignoCrit method is obtained for each triplet resource-process-producing country of the platform molecule purchased for the production of 2-MeTHF. Due to the nature of the indicators selected, this evaluation is generalizable multiple resource-process-producing country for multiple platform molecules.Last but not least these results and their interpretation can be used to implement continuous continuous improvement initiatives within companies, as well as for external external communication in the context of EMS and CSR

Texto completoThis thesis provides an overview on the evolution of commodity markets and focuses on the price behaviour in both the commodity physical and the financial derivatives markets. Instead of directly analysing regulation in the commodity markets, this thesis highlights the market changes and specific market behaviour, which gives potential implications for market regulation.Main results of thesis. This research on regulation of commodity markets has been conducted within two different markets: commodity physical markets and commodity derivatives markets. Results in physical markets confirm the evidence of jump in agricultural commodity prices. Price volatility varies with time and is not constant. Commodity markets’ –at least agricultural markets’- prices oscillated during the period 2007/2008, which coincided with financial crisis. Relatively high frequent and small jumps in commodity prices are probably due to financial market factors instead of market fundamentals.The implication of these results in risk management of agricultural cooperatives is that, although taking into account jump in risk measure, such as VaR does not out-perform traditional VaR with normal distribution. Considering this kind of extreme price variation can be complementary for risk managers when facing a highly volatile commodity market. Findings for financial derivatives markets lead to two conclusions.Firstly, commodity index funds are confirmed again as having a short-term impact on futures prices in most products. Based on the theoretical conclusion about the intermediary role of inventory on the impact of speculation on the commodity market, we have found that commodity index can influence commodity futures prices without necessarily passing through inventory changes, which is probably due to price-inelasticity. Secondly, in relation to the impact of central bank announcements on commodity prices, the study shows that the central bank can be an alternative regulator to influence the commodity market. Additionally, it shows that commodity prices include the information from macroeconomic factors, such as currency rate and inflation rate

Texto completoCommodity prices rise observed during the 2000s being concomitant with the increasing presence of financial agents has sparked the researchers’ interest. This price increase occurred while commodity markets have been transformed by new financial instruments or larger investments in these markets. The first chapter of this thesis are studying the impact on commodities of Exchange-Traded Products (ETPs) whose purpose is to provide investors a passive exposure to commodities. During this study, it is shown that the mechanism (called creation / redemption) used to deliver the performance of the underlying commodity to the investors has an impact on the price of the underlying asset, its volatility and its correlation with the stock market. The second chapter demonstrates that ETPs have become major contributors to the price discovery process whereas traditionally this function was performed by the futures market. The final chapter of this PhD thesis is studying seasonality in both the prices and positions of different types of agents on the futures market for agricultural commodities. The results show that seasonal positions in the futures market have been changed by the increased presence of financial agents. This thesis quantifies and demonstrates that new investment vehicles and an increasing number of positions of financial investors in the futures market have changed the financial and fundamental characteristics of commodity markets

Texto completoThe regulation of agricultural commodity markets is a academic‘s work that evaluates the consequences of the evolution of our society on this essential product. Indeed, its price is subject to many influences. Yet the Law has decided for the moment to turn away from it in the majority. This doctoral work thus tries to determine what are the weak points of the legislations in several fields in order to secure this product whose unconscious value is essential to obtain the social peace that the Law tends to obtain

Texto completoThe situations of international primary commodity markets show phenomena of convergence and divergence in their developments. Price fluctuations which last several years express a succession of phases of overproduction and shortage in almost all of the product markets. These fluctuations are explained by an endogeneous process of adjustment between production and consumption and price as well as phenomena of lagged response. The analysis of the price fluctuations and of endogeneous mechanisms of market lead us to an analysis in medium term and long term. Endogeneous mecanisms are submited to phenomena of overreaction and set a problem of regulation in medium term and long term of the market which leads to different systems of regulation. The major systems of regulation are the producer-price system, the controlled competitive system such as the international product agreement, and finally the overracting competitive system where endogeneous mechanisms are fully acting. The latter is the one which is known currently on most of the market. Common global factors are favouring convergence and divergence of the situations of international primary commodity markets. The pace of general economic activity have repercussions on the decisions of investment in production capacities in the developing countries who produce primary commodities. These global factors concern development strategies of the producing countries in primary commodities and concern also the evolution of the functioning of the economies of industrialised countries as well as the transformation of industrial structures at the national and international level. The cyclical phenomena of primary commodity markets stem from endogeneous mechanisms specific to markets and of the impact of exogenous factors. The factors of convergence can act either as exogenous disturbances which affect simultaneously several markets or by influencing and bringing closer their specific dynamics

Texto completoThe decrease of the part of the lcd's in the world exportations of commodities and the drop in prices justify the place occupied by questions concerning these products in the relations between the north and the south. One of the problems posed by the evolution of the commodity trade is the instability of prices which pain most of the lcd's. This complex phenomenon can be observed and measured. Its the result of multitude factors and can aggravate the instability of the world economy. The financial constraints are not resolved for the lcd's which depend on them. That suppose a recourse to an external financing of the development and require the large modalities of intervention. In order to show the dynamics of mechanisms and their real efficient, an analysis of the results proved the superiority of the compensatory and contingency financing facility on the stabex and the sugar protocal on the buffer stocks regulators. During the 80's the compensatory and contingency financing facility did not have a stabilizing effect ; the european market was not favourable to the acp countries. These systems very original and different each other have the virtue to be simple and cheaper. But owing to the fact that they do not strike at the root of the evil, they can only attenuate it. Does the present institutional frame suffice to adopt measures for a real stabilization ? if the economic analysis does not take into account the market, its is at risk to be exhausted. Our propositions fluctuate between the normalization of the eec schemes and the improvement of the imf systems. The stabilizing action is desirable in all levels at the market level as well as the level of national regional or international institutions. However, the price stabilization in an uncertainty world cant be completed and the success of these programs depends on several elements can we make a good stabilization of prices in the commodity economy? that suppose an evolution in the commodity economy

Texto completoL'analyse théorique de la structure par terme des prix des matières premières étant effectuée, il était intéressant de se pencher sur la façon d'exploiter ses enseignements à des fins de modélisation. C'est l'objet de la deuxième partie du mémoire, qui présente un nouveau modèle de structure par terme – qualifié de modèle asymétrique – justifie les hypothèses qui le sous-tendent, et le positionne par rapport aux autres modélisations.
La troisième partie a pour objectif d'apprécier la qualité de la modélisation effectuée : elle s'intéresse aux résultats des tests empiriques réalisés à partir des modèles de structure par terme. Des simulations me permettent tout d'abord de souligner l'influence des hypothèses concernant le processus stochastique retenu pour les variables d'état et celle du nombre de variables d'état, dans trois modèles différents. Sont ensuite présentés des travaux de nature méthodologique, développés en réponse aux difficultés d'estimation spécifiques que présentent les modèles de structure par terme des prix des matières premières. Enfin, l'exposé des performances des modèles, c'est-à-dire de leur capacité à reproduire la courbe des prix observée, permet de présenter les résultats empiriques obtenus avec le modèle asymétrique.
Deux applications ont été envisagées dans la littérature pour les modèles de structure par terme des prix des matières premières : la couverture dynamique et la valorisation. En ce qui concerne la couverture, la réflexion relative à l'utilisation de modèles de structure par terme est motivée par la volonté de couvrir des engagements à long terme sur le marché physique à l'aide de contrats à terme d'échéance rapprochée. Les travaux portent alors sur la détermination de la stratégie de couverture à mettre en œuvre et sur l'analyse de son efficacité. Dans le domaine de la valorisation, les modèles de structure par terme ont été utilisés en s'appuyant sur la théorie des options réelles. La plupart des recherches entreprises portent sur la décision d'investissement dans le cadre de matières premières minérales, car le caractère irréversible de l'investissement est particulièrement prononcé pour ces dernières. Mes travaux de recherche se sont intéressés à chacune de ces deux applications. Celles-ci ont fait l'objet de plusieurs publications. Elles sont également le sujet de recherches en cours et sont à l'origine de plusieurs projets.

Texto completoThis thesis consists of two independent parts. The first part deals with the dynamic management of physical commodity portfolios, in an illiquid market and under the presence of non traded volume risks. In this framework, we propose a new type of dynamic value measurement for commodity portfolios, which leads to time-consistent decision plannings. A simple numerical experiment illustrates how this new valuation tool can help the portfolio manager assess the synergies between her physical assets and control the risks on final and intermediate wealth. The second part proposes an original model for the joint evolution of two commodity forward curves, capturing at the same time the global and local dependence structures between two economically related commodities. The model is applied here to the US gas and oil markets

Texto completoThe raw materials question has known several sudden changes in the history of international relations and is actually centered around the north-suth relations. Raw materials are at the base of wealth and economical development of any nation. The interest around raw materials is not only limited to supplying problems, it also extends to the supervision of the production and its trading. It explains the importance of the dominion principal concerning natural resources. Raw materials are there for the reason for a aclaim to a new international economic order witch coult permit to restructurize the north-suth trade system. Excessif fluctuations of prices, and deterioration of the exchange relations hip of raw materials exported by all developping countries, are the basic of the north-suth trade. The negociations, led by international suits, between developped and developping countries have not resulted into a transformation of the international economical system, where from the need to work on new rules viable to considere the contrast interest between the two kinds of countries. International law has to fix its duty around that matter
