Overview

In 2021, the highest price levels for investment among the EU Member States were observed in Sweden at 25 % above the EU average, while in the least expensive EU Member State, Croatia, the price level was 36 % below the EU average. These are the main conclusions drawn from the results of two price surveys carried out in 2021 within the Eurostat-OECD Purchasing Power Parities (PPP) Programme. The two surveys cover construction (residential buildings, non-residential buildings and civil engineering works) and machinery, equipment and other products.

The results of the surveys are expressed in price level indices (PLIs), which provide a comparison of countries' price levels with respect to the EU average.

Figure 1 shows the 2021 PLIs for total investment. Norway, Switzerland and Sweden record the highest price levels for investments, with PLIs of 133, 131 and 125, respectively. At the other end of the spectrum, the least expensive countries for investment are Turkey and Albania, with PLIs of 57 and 58.

Machinery, equipment and other products

Figure 2 shows the PLIs for machinery and equipment, including metal products and equipment, electrical and optical equipment and transport equipment (see classification of investment products used). The most expensive countries for machinery, equipment and other products are Iceland, Denmark, Norway, Malta and Switzerland with respective PLIs of 122, 117, 116, 114 and 112, while Poland is the least expensive country, with PLI of 88. The main characteristic shown by this chart is that the price levels for this type of product are relatively homogeneous across countries.

Table 1 shows the countries’ PLIs for the aggregate machinery and equipment as well as for its three main sub-categories: metal products and equipment, electrical and optical equipment and transport equipment. In addition, the PLIs for software are shown. Countries are sorted according to their overall price level for investment shown in the first column. The shaded fields indicate the highest and lowest PLIs per category among all 36 participating countries. The highest and lowest PLIs among the 27 EU Member States are marked in bold.

The results show that Denmark is the most expensive among EU Member States for total machinery and equipment. The Netherlands shows the highest price for transport equipment. As for the other two sub-categories (metal products and equipment, and electrical and optical equipment), the most expensive EU Member State is Malta. Finally, Lithuania is the most expensive EU Member State for software.

By contrast, Poland is the least expensive EU Member State for total machinery and equipment, as well as for two sub-categories: metal products and equipment, and electrical and optical equipment. For transport equipment, Lithuania shows the lowest PLI among EU Member States, while for software, Belgium is the least expensive.

Among all 36 countries, Iceland is the most expensive country for total machinery and equipment, as well as for metal products and equipment, and electrical and optical equipment. The Netherlands has the highest price level for transport equipment, while Lithuania registers the highest PLI for software.

Again taking into account all 36 countries, Poland is the least expensive country for total machinery and equipment. When considering the sub-categories, the lowest PLIs are registered by North Macedonia for metal products and equipment, Lithuania for transport equipment and Turkey for electrical and optical equipment and for software.

At the bottom of the table, coefficients of variation are provided for the euro area (EA-19), the European Union (EU) and the group of all countries participating in the program (All 36). The coefficient of variation is defined as the standard deviation of the PLIs of the respective group of countries as percentage of their average PLI. The higher the coefficient of variation, the higher is the price dispersion in the respective category.

The coefficients of variation at the bottom of Table 1 confirm the relatively low price dispersion across countries for these investment products. The highest homogeneity is visible within the euro area.

Among all 36 countries, software shows the lowest price variation and transport equipment the highest price variation across countries.

Construction

Figure 3 presents the PLIs for construction. The most expensive countries for construction investment are Switzerland, Sweden, Germany and Norway with PLIs of 160, 148, 142 and 141 respectively. On the other hand Turkey, Albania, Bosnia and Herzegovina, North Macedonia, Croatia and Serbia are the least expensive countries for investment in construction, showing price levels below 50 % of the EU average. The lowest construction price levels were observed in Turkey with a PLI of 38.

Table 2 shows the PLIs for the main categories of construction expenditure (residential buildings, non-residential buildings and civil engineering works). Countries are sorted according to their overall price level for investment shown in the first column. As in Table 1, the shaded fields indicate the highest and lowest PLIs per category among all 36 participating countries. The highest and lowest PLIs among the 27 EU Member States are marked in bold.

Table 2: Price level indices for construction and its components, 2021, (EU=100) - Source: Eurostat (prc_ppp_ind)

Sweden is the most expensive EU Member State for two construction sub-categories (residential and non-residential buildings), while Finland has the highest price level for civil engineering works. At the other end of the spectrum, the least expensive EU Member State for construction investments is Croatia, which is also the least expensive country for non-residential buildings. For the sub-categories residential buildings and civil engineering works, the lowest PLIs are shown by Romania.

Among all 36 countries, Switzerland has the highest price levels for all sub-categories: residential buildings, non-residential buildings and civil engineering works. Turkey was the least expensive country for residential and non-residential buildings sub-categories, while Bosnia and Herzegovina was the least expensive for civil engineering works.

Price dispersion is higher within the 36-country group. It is less significant in the euro area (EA-19) than in the EU as a whole. Price dispersion for all categories of construction is higher than that for total investment, due to the higher share of labour input into construction and the high dispersion of wages across countries. Price dispersion is the highest for residential buildings, followed by non-residential buildings.

Data sources

The data in this article are produced by the Eurostat-OECD Purchasing Power Parities (PPP) Programme. The full methodology used in the programme is described in the Eurostat-OECD Methodological manual on purchasing power parities available free of charge from the Eurostat website.

The PPP concept

In their simplest form PPPs are nothing more than price relatives that show the ratio of the prices in national currencies for the same good or service in different countries. For example, if the price of a hamburger in Sweden is 28.60 Swedish krona and in Italy it is 2.76 euro, the PPP for hamburgers between Sweden and Italy is 28.60 krona to 2.76 euro or 10.36 krona to the euro. In other words, for every euro spent on hamburgers in Italy, 10.36 krona would have to be spent in Sweden in order to obtain the same quantity and quality – or volume – of hamburgers.

Published PPPs usually refer to product groups or broad aggregates like gross domestic product (GDP) rather than to individual products. However, these aggregate PPPs are based on data for individual goods and services.

Price level indices

Price levels as presented in this publication are the ratios of PPPs to exchange rates. They provide a measure of the differences in price levels between countries by indicating for a given product group the number of units of common currency needed to buy the same volume of the product group or aggregate in each country.

Price level indices (PLIs) provide a comparison of the countries’ price levels relative to the European Union average: if the price level index is higher than 100, the country concerned is relatively expensive compared to the EU average, while if the price level index is lower than 100, then the country is relatively inexpensive compared to the EU average. The EU average is calculated as the weighted average of the national PLIs, weighted with expenditures from national accounts, corrected for price level differences.

Price level indices are not intended to rank countries strictly. In fact, they only provide an indication of the order of magnitude of the price level in one country in relation to others, particularly when countries are clustered around a very narrow range of outcomes. The degree of uncertainty associated with the basic price data and the methods used for compiling PPPs may cause minor differences between the PLIs and result in differences in ranking which are not statistically or economically significant.

The impact of exchange rate changes on PLIs

As explained above, the PLI for a given country is calculated as its PPP divided by its annual average exchange rate to the euro. This implies that exchange rate movements have an impact on the PLIs. The depreciation of a country’s currency against the euro will make the country less expensive in comparison to euro area countries and this will be shown as decrease of the relative price level expressed in the PLI.

Main characteristics of the survey on prices for machinery, equipment and other products

The survey on prices for machinery, equipment and other products is carried out every 2 years. The last survey was carried out in April, May and June 2021. Countries collected prices for around 500 items, divided over nine sub-groups. The survey covers the three main sub-categories of machinery and equipment (metal products and equipment; electrical and optical equipment; and transport equipment) as well as the software category.

From the sub-groups listed as investment categories, no prices are collected for other transport equipment, boats, steamers, tugs, floating platforms and rigs, locomotives, rail-cars, vans, wagons and other rail equipment, aircrafts, helicopters, hovercrafts and other aeronautical equipment, and products of agriculture, forestry and other products. PLIs for these sub-groups are estimated taking PPPs of other sub-groups as proxy.

Prices refer to purchasers’ prices including non-deductible VAT.

Main characteristics of the survey on construction prices

The 2021 survey on construction prices, whose results are published in this article, was carried out in May, June and July 2021.

Countries collected prices for a list of "bills of quantities", which are comparable construction projects such as a detached house, an office building or an asphalt road. Each bill of quantities consists of a number of chapters or major components (like earthworks, concrete, masonry, etc.) which are made up of items or elementary components (like excavation of the terrain, dumping and compacting of soil, etc.).

The construction projects are divided into 3 sub-categories: residential buildings (comprising 5 bills of quantities: a detached house, a house representative for Portugal, a house representative for Nordic countries, an apartment building and a renovation of a detached house), non-residential buildings (comprising 2 bills of quantities: a light industrial building and an office building) and civil engineering works (also 2 bills of quantities: an asphalt road and a bridge).

Countries are asked to collect purchasers’ prices for the bills of quantities, i.e. prices actually paid in markets for the elementary components that make up those bills of quantities and the additional expenses incurred that build up to the project total cost paid by the client. Non-deductible VAT is added to these purchasers’ prices.

Context

Purchasing power parities (PPPs) are indicators of price level differences across countries. PPPs tell us how many currency units a given quantity of goods and services costs in different countries. PPPs can thus be used as currency conversion rates to convert expenditures expressed in national currencies into an artificial common currency, the purchasing power standard, eliminating the effect of price level differences across countries.

The main use of PPPs is to convert national accounts aggregates, like the gross domestic product (GDP) of different countries, into comparable volume aggregates. Applying nominal exchange rates in this process would overestimate the GDP of countries with high price levels relative to countries with low price levels. The use of PPPs ensures that the GDP of all countries is valued at a uniform price level and thus reflects only differences in the actual volume of the economy.

PPPs are also applied in analyses of relative price levels across countries. For this purpose, the PPPs are divided by the current nominal exchange rate to obtain a price level index (PLI) which expresses the price level of a given country relative to another, or relative to a group of countries like the EU.

The common rules for the provision of input data, and for the calculation and dissemination of PPPs, are laid down in Regulation (EC) No 1445/2007 of the European Parliament and of the Council of 11 December 2007.
