Sýkorová, Lucie ; Lahvička, Jiří (advisor) ; Svoboda, Miroslav (referee)
This thesis investigates how the purchase price of aluminium, copper, iron, advertising campaign, weather and other factors influence the offered quantity of metals by private persons (in general and by sex). These daily data are from period January 2009 -- December 2011 and obtained from a scrap yard. I proved that increase in price of aluminium about 1 % causes the growth of its supply about 1,49 %. The same increase in price of iron causes the growth of its supply about 0,64 %. I prove that the best way of promotion is radio spot. My work shows that supply of iron reaches its maximum at daily temperature 9,3°C and it is negatively influenced by rainy weather. Easy substitution of offered metal of copper and iron - in case of men - indicates the presence of illegal supply, as shown by value of cross price elasticity of supply of copper -0,7. Next indicator of illegal supply is a strong increase of supply of copper by both sexes on Saturday. (It is based on research Panáček (2012)). It is 60 % for men and 100 % for women. There is a fall of supplies of aluminium and iron from both sexes on the same day.
