Merjenje inflacije v Sloveniji s ceniki spletnih trgovin

REMEC, SAMO (author), Vavpotič, Damjan (mentor)

V tej diplomski nalogi smo merili inflacijo preko cenikov spletnih trgovin. Najprej razložimo, kaj je inflacija in kako se jo meri v praksi. Nato povzamemo delo trenutnih projektov, ki jo merijo na omenjen način. V drugem delu razložimo naš pristop k zbiranju podatkov. Opišemo vse tehnologije, ki smo jih uporabil in na težave, na katere smo naleteli. V zadnjem delu primerjamo pridobljene podatke z uradnimi merami inflacije. Približno polovica kategorij se dobro ujema z uradnim indeksom, druga polovica pa ne. Skupni indeks inflacije se v opazovanem obdobju lepo ujema. Ugotovili smo tudi, da trgovci na drobno spremenijo med 0,8 % in 1,1 % cen vsak dan. Implicitno trajanje cene je tako med 91 in 125 dni, kar je bistveno daljše, kot rezultati obstoječih raziskav iz Evrope, ZDA in držav Južne Amerike. Povprečna sprememba cene v istih trgovinah je bila velika (-21,2 % in 26,5 %) in približno enaka, kot v ZDA.

• Title: Measuring inflation in Slovenia using online prices

Abstract

In this thesis we measure price inflation with prices from online retailers. First, we explain what inflation is and how it is measured in practice. Then we summarise the work of current projects which use this technique. In the second part we explain our approach to collecting data. We describe all the technology used and all the problems we encountered. In the last part we compare our results with official inflation measures. About half of the individual categories match nicely with the official price index, the other half not so much. In the observed period the total price index seems to match nicely. We also found that retailers change between 0.8 % and 1.1 % prices every day. Implicit price spell duration is therefore between 91 and 125 days, which is considerably longer than results from existing studies in Europe, USA and South America. Average price change from the same retailers was large (-21.2 % and 26.5 %) and about the same as in the USA.
