In some countries a Paasche price index based on unit values is compiled as a proxy for a true Paasche (or Laspeyres) price index on the basis of prices. This is for example the case in German foreign trade statistics. Unit values are average prices referring to a 'commodity number' (CN), that...

This paper derives formulas for additive "chained volume measures" (CVMs) of GDP subaggregates depending on the underlying GDP quantity index. In turn, this paper explains why the formulas used in current practice yield nonadditive CVMs. This paper's additive formulas have significant practical...

Despite the intensive efforts made by economists to examine regional income inequality in China, limited attention has been paid to disentangle the contribution of regional price differentials. This paper examines regional price differential in urban China over the period 1986 to 2001. Spatial...

The goal of this paper is to theoretically and empirically demonstrate the consequences of different imputation methods, using recent data from the International Price Program. We suppose that prices are missing due to random or erratic reporting. We consider three different imputation methods:...

Price indices for heterogenous goods such as real estate or fine art constitute crucial information for institutional or private investors considering alternative investments in times of financial markets turmoil. Classical mean-variance analysis of alternative investments has been hampered by...

It is often argued that price indexes do not fully capture the quality improvements of new goods in the market. Because of this shortcoming, price indexes are perceived to overestimate the actual price increases that occur. In this paper, I argue that the quality bias in price indexes is just as...

This paper’s framework for GDP in chained prices yields GDP in constant prices as a special case of constant relative prices, i.e., these GDP measures differ only when relative prices change. The framework has a novel additive procedure, counter to the prevailing view that GDP in chained...

This paper applies the Johansen Cointegration procedure to test the law of one price (LOOP) for twelve international markets of paintings using semi-annual data for the period 1985-2007. Cointegration test is performed in a pairwise arrangement. Price index for each market is estimated using the...
