Dankzij uitvindingen op het gebied van getallen begrijpen we steeds beter hoe de natuur in elkaar zit. Zo konden de Babyloniërs met hun zestigtallige stelsel duizenden jaren geleden al de beweging van planeten uitrekenen. Nog maar enkele eeuwen terug leidde de invoering van de nul tot een wetenschappelijke revolutie. En hoe zouden we nu virusverspreiding moeten beschrijven zonder het exponentiële getal e?Dit boekje bespreekt op een leuke en toegankelijke manier de belangrijkste getalsuitvindingen uit de geschiedenis. Het gaat van één via nul naar oneindig en daar voorbij – met speciale aandacht voor buitenbeentjes zoals het bespotte verzinsel i, de gehate wortel van twee en de gehypete gulden snede. Ondertussen kom je erachter wat getallen nou eigenlijk zijn, en waarom ze zo ontzettend handig zijn bij het beschrijven van de wereld om ons heen.(bron: covertekst)

This book deals with the currently most relevant topics in price index numbers theory and practice. The problem of the harmonization of Consumer Price Indexes (CPIs) and the time-space integration of baskets is analyzed at the EU-zone level, with methodological and practical proposals on how to proceed for an overall treatment of the matter. Another issue is comparisons between Purchasing Power Parities (PPPs) and CPIs. Likewise, the construction of sub-indexes for households, economic and social groups is investigated, in order to obtain specific inflation measurement instruments. The book provides evidence from the most updated databases. Among the other issues treated in this book are spatial comparisons of price levels through PPPs and the international comparisons of macroeconomic aggregates, a re-consideration of index numbers theory, the measurement of production in non-market services, deflation problems, and price indexes in financial markets.
