In addition, several guest lectures will contribute to specific topics of the course.
Many decisions in agriculture and related industries have to be made under uncertainty. Risk, however, adds a considerable degree of complexity to the decision making process. This course presents the theoretical concepts of rational choice under uncertainty and develops the building blocks for risk management in agribusiness. Once the necessary statistical tools are reviewed, various indicators of the firm's risk exposition are discussed, including Value at Risk (VaR) and Expected Tail Loss (ETL). Moreover, the foundations of stochastic optimization are presented. The theoretical part enables the participants to understand the most important risk management tools, as insurance, futures, financial options, real options or weather derivatives. Much emphasis is put on the numerical aspects of risk management. For example, participants will be practically advised to use stochastic simulation and genetic algorithms.
