This thesis paper explores how various actors gathered around bottled water when a ban was put into place in Concord, Massachusetts. The objective has been to answer the following questions: How does an apolitical commodity become a political one? Specifically, how does bottled water move from being an apolitical commodity to become a highly political one? What does this mean for environmental politics? I situate my theoretical approach within Martha Kaplan’s research with fountains and coolers. I use Bruno Latour to show in which ways this ban became a matter of concern, as well as how the ban and the plastic bottle are actors. I conducted fieldwork in Concord and I interviewed participants. My findings reveal that the ban brought meanings to the surface and challenged them or supported them in various ways. The discussions turned from the impact of bottled water on our environment to the political impact of bottled water companies and large corporations on local Concord issues.

A report on social consequences of neoliberal trade policies and the commodification of food, and the international efforts of small farmers to counteract the worst of these consequences. Social justice movements like fair trade and local food have emerged with the aim to expose the direct impacts on food producers. These movements co-exist while achieving their respective and mutual goals. Themes explored are: the fight against neoliberal globalization and mainstream trade, labour practices (workers' rights, fair wages, safe work environments,) sustainability (environmental practices, food security,) community and economic development and consumer awareness of aforementioned issues. Although these are global issues, close attention is paid to recent mobilization efforts in Canada and Manitoba among small food producers, farmers’ unions and related non-government organizations.

Food security is a global topic of discussion and agricultural sectors play a vital role in the provision thereof. In South Africa the agribusinesses are some of the key players in providing financing, risk management and market advisory services to producers. Since the deregulation of the grain industry during 1996, many of these agribusinesses have converted their business form from cooperative to company and therefore adhere to International Financial Reporting Standards (IFRS). These agribusinesses trade commodity derivatives on the South African Futures Exchange (SAFEX) to hedge themselves and their producers against commodity price risk. Globally there has been a tremendous increase in the use of derivatives and other financial instruments and with the emergence of these new and more complex financial instruments, accounting regulations had to follow these developments. The applicable accounting practices at the time were considered as being insufficient and being applied inconsistently. The major global standard setters namely IASB and FASB separately tried to develop adequate standards to address the accounting treatment of these products. The IASB developed International Accounting Standard (IAS) 39 dealing with the recognition and measurement of financial instruments, while the FASB issued Financial Accounting Standard (FAS) 133. These two standard setters have signed the Norwalk Agreement committing to plans to converge the IFRS and US accounting standards. This study focused on the application of IAS 39, with reference to commodity derivatives, with the main research objective being to investigate the accountancy implications of commodity derivatives in the South African agricultural sector. Furthermore it also serves to establish a standard methodology for the interpretation of IAS 39 and to serve as a benchmark and best practise for South African agribusinesses and commodity processors. For this purpose seven case studies were investigated by utilising a developed questionnaire, an illustrative flow diagram of IAS 39 and recorded structured interviews with the respondents. The accounting treatment of commodity derivatives was investigated by utilising nine transaction types which are typically found when producers sell grain to an agribusiness or a processor purchases grain from an agribusiness. The seven case studies were identified by utilising convenience sampling (unrestricted non–probability sampling). A literature review and empirical study were conducted. The findings on the accounting treatment of commodity derivatives were communicated thematically. The main findings were discussed during interviews with representatives of the technical departments of three of the Big Four audit firms in South Africa. A discussion of similar studies performed globally was performed. The recommendations following from this research study include that entities carrying “own use” inventory and applying hedge accounting can elect to apply the base adjustment consistently as part of their accounting policy on the valuation of inventory. Entities holding grain inventory for trading purposes should, based on industry practice, fair value such inventory. Various recommendations regarding the classification of a supply contract with a producer (as defined in a pre–season fixed price contract) depending on whether an entity applies hedge accounting or not, were made. Recommendations regarding the determination of fair value include that, based on industry practice and guidance by IAS 39, the SAFEX–based price should be utilised to fair value derivatives and to fair value inventory held by commodity–broker traders. The fair value movement on the option contracts taken out on behalf of the producer by an agribusiness should be transferred to the relevant producer's loan account. The recommendations concluded with a recommendation that entities should proactively consider and plan the impact of the replacement of IAS 39 on current business practices. Areas for further research could include investigating the accounting treatment of commodity derivatives of the newly issued accounting standards on financial instruments by IASB and the impact of these new standards on the business practices of entities. / Thesis (Ph.D. (Management Accountancy))--North-West University, Potchefstroom Campus, 2011.

Various models driven by a hidden Markov chain in discrete or continuous time are developed to capture the stylised features of market variables whose levels or values constitute as the underliers of financial derivative contracts or investment portfolios. Since the parameters are switching regimes, the changes and developments in the economy as soon as they arise are readily reflected in these models. The change of probability measure technique and the EM algorithm are fundamental techniques utilised in the optimal parameter estimation. Recursive adaptive filters for the state of the Markov chain and other auxiliary processes related to the Markov chain are derived which in turn yield self-tuning dynamic financial models. A hidden Markov model (HMM)-based modelling set-up for commodity prices is developed and the predictability of the gold market under this setting is examined. An Ornstein-Uhlenbeck (OU) model with HMM parameters is proposed and under this set-up, we address two statistical inference issues: the sensitivity of the model to small changes in parameter estimates and the selection of the optimal number of states. The extended OU model is implemented on a data set of 30-day Canadian T-bill yields. An exponential of a Markov-switching OU process plus a compound Poisson process is put forward as a model for the evolution of electricity spot prices. Using a data set compiled by Nord Pool, we illustrate the vast improvements gained in incorporating regimes in the model. A multivariate HMM is employed as a framework in providing the solutions of two asset allocation problems; one involves the mean-variance utility function and the other entails the CVaR constraint. Finally, the valuation of credit default swaps highlights the important considerations necessitated by pricing in a regime-switching environment. Certain numerical schemes are applied to obtain approximations for the default probabilities and swap rates.

Historical evidence has shown that increases in coffee prices, though generating a short term gain in export earnings for producers, also lead to increased plantings of the coffee crop. This in turn leads to overproduction and a subsequent drop in coffee prices. The establishment of the International Coffee Agreements was meant to stabilize this fluctuating behaviour in coffee prices. / The purpose of this paper is to present an overall analysis of coffee prices in order to predict the future course of prices under two circumstances. First, when the international coffee market is governed by the mandates of the International Coffee Agreements and secondly, when the market operates under free market conditions. The paper also attempts to draw parallels between the structure and mechanisms of the markets of coffee and tea. The first part of this paper provides a background study of the markets of coffee and tea including a discussion of the commodity cartels which have been signed to date in both markets. Part two provides a historical analysis of prices in both markets, followed by an econometric analysis of the demand for coffee in the largest consuming country in the world, the United States.

This thesis proposes a critical study of the techniques and motives behind modern commodity feminist advertising, focusing on the appropriation of the “young girl” as a symbol of the feminist cause. This evolving trend in advertising, building upon new movements of empowerment and the recent proliferation of the online feminist space, is shifting the logics of consumption by marketing feminist ideology and activism through consumer purchasing power. By prompting consumers to believe that their purchases can make a significant change, companies are developing brand loyalty in their key marketing demographics by using the image and rhetoric of the “young girl” to tap into a term I call “anti-nostalgia,” a nostalgia whereby women leverage the inherent sentimentality of childhood with a constructive understanding and rejection of the destructively sexist climate they experienced to combat these sociocultural conditions for future generations. Joining theoretical research on branding, user-generated content, and the neoliberal ideology of the consumer-citizen, I argue that these advertising campaigns, coupled with online spaces for public interaction and participation, effectively create channels for their target consumers to contribute to this commodified form of activism. In reality, however, these “feminist” purchases are simply forms of consumer self-therapy in a modern political climate of systemic gender discrimination.
