This book deals with many of the most relevant topics in price index numbers theory and practice. The problem of the harmonization of CPIs and the time-space integration of baskets is analyzed at the Eu-zone level, with methodological and actual proposals on how to proceed for an overall treatment of the matte. Likewise, the construction of sub-indexes for households economic and social groups is investigated, in order to obtain specific inflation measurement instruments. Evidence from most updated databases is given. The questions of the spatial comparisons of price levels through PPPs and th.

In 150 years Italy transformed itself from a poor and backward country into one where living standards are among the highest in the world. In Measuring Wellbeing, Giovanni Vecchi provides an innovative analysis of this change by drawing on family accounts that provide engaging insights into life and are the "micro" data that create the foundations for the "macro" picture of variations and fluctuations in the development of Italy. Vecchi provides a nuanced account of the changes. He emphasizes that the concept of wellbeing is multidimensional and must include non-monetary aspects of life: nutrition, health and education, as well as less tangible elements such as freedom or the possibility to exercise one's political rights. The book deals with this polyhedral nature of wellbeing. Among the insights are that Italians succeeded in combining growth with equity, but that the gap between the North and South did not narrow; the while longevity has increased, education has not improved as much as it could have; and that for close to three decades, Italy's virtuous path has come to a halt: the wellbeing of the Italian people is at the crossroads between progress and decline. Measuring Wellbeing engagingly combines a unique dataset and an innovative statistical method that can be adapted to other countries.

The theory of relativity describes the laws of physics in a given space-time. However, a physical theory must provide observational predictions expressed in terms of measurements, which are the outcome of practical experiments and observations. Ideal for readers with a mathematical background and a basic knowledge of relativity, this book will help readers understand the physics behind the mathematical formalism of the theory of relativity. It explores the informative power of the theory of relativity, and highlights its uses in space physics, astrophysics and cosmology. Readers are given the tools to pick out from the mathematical formalism those quantities that have physical meaning and which can therefore be the result of a measurement. The book considers the complications that arise through the interpretation of a measurement, which is dependent on the observer who performs it. Specific examples of this are given to highlight the awkwardness of the problem.

This publication provides a summary of the key methodological issues surrounding indicators and statistics on the space sector and the larger space economy.
