Abstract

In years 2007-2008, prices of food and agricultural products surged dramatically all round the world. The time series analysis of monthly global prices from 1990 through April 2010 shows that prices for several commodity groups in 2007-2008 outpaced long-run price increases, suggesting many factors attributed to this phenomenon. This study tries to answer the question whether and how financial investments have affected those increases. The data for the study were obtained from FAO, US Commodity Futures Trading Commission and other public financial information. / Synopsis. W latach 2007-2008 zaobserwowano w skali światowej drastyczny wzrost cen żywności oraz surowców rolnych. Analiza szeregu czasowego globalnych cen od stycznia 1990 do kwietnia 2010 wskazuje, że tempo ich zmian w latach 2007-2008 w przypadku wielu grup towarowych wyraźnie przewyższało średnią miesięczną stopę wzrostu dla całego okresu. Za wyjątkowym krótkookresowym wzrostem stało przypuszczalnie wiele przyczyn. W opracowaniu podjęto próbę odpowiedzi na pytanie, czy i w jaki sposób inwestycje finansowe przyczyniły się do tego zjawiska. Dane zaczerpnięto z bazy FAO oraz raportów Komisji ds. Obrotu Kontraktami Futures na Surowce w USA.
