The author considers the history of international comparisons of macroeconomic indicators carried out periodically from 1960th up to the end of the 1980th within the framework of the Council for Mutual Economic Assistance (CMEA). As a result of these comparisons extensive information on economies of the countries of this organisation was collected and processed; it was used to establish economic cooperation between the CMEA members. It is noted that the CMEA program is in many respects similar to the ongoing Program of international comparisons of the GDP (ICP) that is carried out following a decision by the UN Statistical Commission. This mainly concerns the computation methods of purchasing power parities. At the same time, the article considers some peculiarities of the CMEA methodology.

In a report published in June 2012 the Business Council of Australia (BCA) reported that it costs considerably more to build a variety of types of infrastructure in Australia than it does in the US. Airports (90% more costly) and hospitals (62%) were quoted as the worst cases with other projects ranging from 26% to 43% more. They used these figures to conclude that Australia is a high cost, low productivity environment for building infrastructure projects. These claims were based on cost/m2 figures published by a major international construction consultancy. The method used by the BCA is flawed in two ways: one is the in the use of costs that are recognised as giving only the broadest of indications of probable costs and the second is the use of exchange rates to convert Australian construction costs to US dollars. Careful analysis of the methodology used, supported by a series of other comparisons based on other data sources and other conversion factors (purchasing power parities or PPPs), suggests that in real terms it probably costs no more to build in Australia than it does in the US and that it may well be cheaper to build in Australia than it is in the US.

We show that online prices can be used to construct quarterly purchasing power parities (PPPs) with a closely matched set of goods and identical methodologies in a variety of developed and developing countries. Our results are close to those reported by the International Comparisons Program (ICP) in 2011 and the OECD in 2014, and can be used to obtain more up-to-date estimates of real consumption across countries without the need for consumer price index extrapolations. We discuss advantages and limitations associated with the use of online prices for PPs, including issues of representativeness and limited coverage of product categories and countries.
