This Diploma thesis focuses on a set of commodities dealt on world-wide trades. It mainly discuss the business environment of commodities with physical delivery, not so much the speculative deals. The goal of the Diploma thesis is to select a set of appropriate commodities for Internet (web-based) business. The first part contains the overview of the actual level of knowledge in the area of Internet-based business with commodities. The second one focuses on the analysis of the commodity exchange and non-commodity exchange environment in Czech Republic and the world. Result of each analysis is a list of commodities dealt on the specific market. It also contains the comparison the commodity exchange and non-commodity exchange environment. The goal of before mentioned steps was to define the set of commodities for trading on an Internet portal -- opentrade.cz. Third part describes the functionality of the opentrade.cz and its' specifics -- barter trades. It also contains the list of commodities.

The study focuses on tariff-linked (or commodity-linked) agreements entered into between a power utility and commodity producers. The main purpose of these types of agreements is to link electricity tariff payable by commodity producers to the price of the commodity produced thereby transferring a certain level of commodity price risk to the power utility. The study looks at risk management practices of a power utility company with a particular reference to tariff-linked agreements. Also, the study critically analyses risk hedging mechanisms put in place by the power utility. The report makes practical recommendations, where applicable, in dealing with these risks. Risk management continuously evolve to meet the challenges of complex financial world. Despite the latest sophisticated risk management tools available commodity producers still encounter difficulties to hedge the price risk. The challenge for the power utility is the application of new risk management tools to effectively manage price risk. / Business Management / M.Com. (Business Economics)

This study defines the need and practicality of measuring and determining the metrics and success indicators for an international commodity marketing office for a bulk material resource mining corporation and more particularly for the recently established international marketing office of the specific corporate. The methodology of the study offers the industry a comprehensive investigative process to prove the viability of various quantifiable and qualifiable metrics and success indicators as well as value proposition potentials for an international commodity marketing office were found. The expected and high priority functions of the international marketing office were Customer relationship management and Competitive & Market intelligence The measurement criteria are collated within 4 main groupings namely General, Products, Markets and Financial. The specificity of the monitoring points and the fact that they are derived from non-financial and non marketing bases proves that their determination and measurement is viable and will further increase the potential value added by a coal commodity marketing office. Based on similarities between coal commodity market drivers and drawing this relation back through the generality of the bulk commodity marketing concepts and processes, the same benefits and or metrics may also be true for all commodities and their relevant marketing offices.

4 pp. / Wheat Production on Lettuce Beds / In 2009, over 56,000 acres were planted to wheat in Arizona, all of which following either a lettuce or cotton crop. For wheat grown in the region, the conventional tillage sequence prior to planting can be tied to as many as seven field operations that consume valuable time, labor, and resources. In this study, our aim was to determine the effectiveness of reducing the number tillage (minimum till) operations in fields immediately following lettuce harvest. And demonstrate to Southwest wheat producers a means for conserving time, fuel, and resources. Growing wheat on lettuce beds immediately following lettuce harvest did not significantly reduce grain yield or quality. Although the regrowth of the previous crop can have significant implications for Durum grown with minimum tillage if not managed effectively, lodging was not a significant factor in this study as the degree of lodging was similar in both growing systems. The significant savings in fuel, labor and time, with no apparent reduction in Durum yield or quality, may be a significant benefit to wheat producers who incorporate minimum tillage practices following a lettuce crop.

Using farmer surveys the smallholder commodity systems of Brassica rapa L. subsp. chinensis and Solanum retroflexum Dun. in Vhembe District, Limpopo Province, South Africa were described and analysed. Production, transaction and consumption of the two vegetables were deeply embedded in the food, trade and farming systems of local people. The cultivation systems, which appeared effective, were developed by borrowing elements from the systems of other crops to which new knowledge specific to B. chinensis and S. retroflexum were added. Several elements of the production systems that could benefit from scientific enquiry were identified. These included genetic improvement and the optimisation of planting density and nutrient supply.

The thesis examines the effects of geopolitical events on global crude oil, wheat and aluminum prices. Geopolitical events have the potential to disrupt the production and supply of commodities to markets, affecting prices. Path analysis models that mirror crude oil, wheat and aluminum markets are constructed using theories specific to each commodity to measure how substantial the impacts of different variables are upon prices. Vector error correction models are then employed to test if individual geopolitical events have long-term effects on prices. An analysis of production and exports of commodities in regions and countries affected by geopolitical events is conducted to determine how severely production is disrupted. A basic examination of prices before, during and after geopolitical events is conducted to understand how quickly drivers of commodity prices can shift between geopolitical events and supply and demand fundamentals. It also serves to show how quickly prices revert to pre-event levels following a geopolitical event.

This Thesis is dedicated to the variance decompositions from the VAR model un- der the Diebold, Yilmaz (2012) methodology combined with the Baruník, Křehlík (2017) method of frequencies that was used to create traditional and directional spillover tables to be compared under different frequencies. Diverse markets vari- ables were used for the analysis during the period 1/6/1999 to 29/6/2018. The S&P 500 Index represented the financial markets, EUR/USD and YEN/USD rep- resented the Forex markets, and eight types of commodities: Crude Oil, Natural Gas, Gasoline, and Propane represented energy commodities and Corn, Coffee, Wheat, and Soybeans represented food commodities. This analysis contribute to understanding of the dynamic frequency connectedness in case of a differentiated system of markets. The main finding was the strongest short-frequency reaction to shocks in case of all variables, which is opposite behavior than usually observed in banking sector frequency dynamics analyses.
