This dissertation aims at better understanding how the variable behaves, as well as at establishing which factors influence its price. This dissertation is organised in different chapters. The first chapter covers the relevant literature review and was extended to provide some framework on the history of gold and its major events. The second chapter briefly explains the concepts used to study the time series and building the econometric models. In the third chapter, the econometric model was built with the relevant variables, and an attempt was made to explain at each step of the way the underlying reasons for the relevance of every variable included. Lastly, the findings were interpreted, and conclusions drawn, elaborating as much as possible on the resulting data.
O objetivo desta dissertação é compreender melhor o comportamento da variável, e conseguir perceber os fatores que influenciam o seu preço. A presente dissertação está estruturada por capítulos. Durante o primeiro capítulo realizou-se a revisão de literatura, que se estende sobre a história do ouro e os seus grandes acontecimentos. No segundo, explicou-se sucintamente os conceitos utilizados para estar as séries temporais e contruir os modelos econométricos. Terceiramente, construiu-se o modelo econométrico com as variáveis que assim faziam sentido, sempre tentando explicar em cada passo as devidas razões. Por fim, interpretaram-se os resultados obtidos, tentando desenvolver ao máximo o pensamento de acordo com os dados.
