Růst cen drahých kovů
Krčmař, Jan ; Kollár, Miroslav (advisor) ; Fiala, Martin (referee)
Tato práce se zabývá růstem cen drahých kovů a zaměřuje se na zlato, stříbro a platinu. Nejprve popisuje rozdělení komodit, mezi které tyto vzácné kovy patří. Ceny sledovaných kovů za posledních 10 let rostou a tato práce hledá důvody tohoto růstu. Cena se na trhu tvoří vztahem mezi nabídkou a poptávkou. Proto u každého kovu sleduji jak jeho těžbu (nabídku), tak i jeho využití (poptávku). Čína a Indie patří mezi největší poptávající země zlata a stříbra, a proto se jim věnuji podrobně. Na konci každé kapitoly uvádím důvody růstu cen jednotlivých kovů a zkoumám vztahy mezi nimi.
