Quality adjustment of price indexes affects the analysis of many sensitive economic issues, such as real growth, productivity, international competitiveness, real wages, per-capita consumption and poverty, other than inflation. Hedonic methods are often recommended and increasingly used in the...

Inflation is currently low and falling in the OECD area. A side effect of these facts is that they made harder the task of price index compilers. First of all, researchers and analysts are moving their attention from aggregate price dynamics to price differentials (among products, markets,...

Estimation of spatial housing price indices requires a housing market segmentation into local sub-markets. In this paper, we use geographically weighted regression model (GWR) to take account for spatial heterogeneity of housing attribute marginal prices. Estimated marginal prices are then used...

This paper proposes a methodology for a spatial cost index of housing that considers spatial heterogeneity in properties across regions. The index is built by combining three different techniques to reduce the spatial heterogeneity in housing: Quasi-experimental methods, hedonic prices and...

Given the highly kurtotic and positively skewed characteristics of cross-sectional distribution of price, asymmetric trimmed-mean is the best approach in extracting the statistical medium-term trend of inflation. This paper uses asymmetric trimmed-mean approach to measure core inflation in...

This paper explores the extent to which goods follow systematic pricing patterns over their life cycle. The theoretical literature, and anecdotal evidence, often suggests that new products are often introduced at high prices which decline as the good ages while, older goods exit the market at a...

Stochastic approach to index number (and its change) has recently attracted renewed attention of researchers as it provides the standard error of index number (and its change). One of the most important uses of index number is in the case of measurement of the general price level in an economy...

The fact that the famous price index of Laspeyres is unable to pass the so called inversion test (IT) gave rise to the idea that this formula tends to measure "spurious inflation" which renders it useless and fallacious. In the IT prices and quantities of n goods, relating to two periods, the...

In the U.S., the objective of consumer price index (CPI) measurement is to measure the cost of living. However, the current CPI or, in other words, cost of living index (COLI) measures the cost of living in a static optimization problem. This paper proposes a new method to construct a dynamic...

Economist have noted for decades that Consumer Price Index (CPI) in the developed countries is overstating inflation by 0,5-2,0% per year. A significant part of such a bias is found to be caused by the presence of technology products and differentiated products in CPI. An increasing weight of...
