This Compendium describes the contribution of CompNet to the improvement of the analytical framework and indicators of competitiveness. It does this by presenting a comprehensive database of novel competitiveness indicators. These are more than 80 novel indicators designed by CompNet members that capture macro, micro and cross-country dimensions, thus providing a comprehensive view of the competitive position of EU countries and their peers. A short description of each innovative indicator – consisting of the motivation for use, an intuitive explanation of the methodology and a list of advantages and drawbacks – helps the reader to better understand the use of the novel variables. On the analytical side, issues related to the definition of competitiveness are discussed and the empirical evidence on the link between competitiveness indicators and policy objective variables such as real GDP per capita and external trade performance is presented.

This study examines the marginal effects of traditional determinants of exports and imports with a focus on the role of price competitiveness in restoring external balances. It is a first attempt to compare marginal effects of various harmonised competitiveness indicators (HCIs) on both exports and imports of both goods and services across individual euro area countries. We find evidence that HCIs based on broader cost and price measures have a larger marginal effect (with some exceptions) on exports of goods. Exports of services are sensitive to HCIs in big euro area countries and Slovakia, where exports of services are also found more sensitive to competitiveness indicators based on broader price measures. Imports of goods and imports of services are quite insensitive to changes in relative prices. Finally, in some cases measures of fit indicate that a large unexplained residual part is present, implying that other non-price related factors might play an important role in driving foreign trade.

In recent years, government revenues in many EU countries experienced significant and erratic changes, which, a priori, could not be fully explained by macroeconomic developments or by discretionary fiscal policy measures. We investigate this issue by estimating “unexplained” changes in tax and social contribution revenues, based on proxies for tax revenue bases and elasticities commonly used for forecasting or cyclically adjusting government revenues and taking into account estimates of the impact of legislation changes. This is done for a selection of EU countries, including the “big five” euro area countries (Germany, Spain, France, Italy and the Netherlands) together with Ireland, Latvia and Portugal. We also undertake the same exercise using alternative tax base proxies, either taken from forecasting models or on the basis of our knowledge of the tax system in each country. The results show that, in the aggregate, revenue windfalls and shortfalls have exhibited a broadly cyclical pattern, driven mainly by developments in profit-related taxes and, to a somewhat lesser extent, VAT. Other, more structural factors also play a role, such as declining consumption of fuel and tobacco, as well as factors specific to individual countries, such as developments in property markets. The estimated revenue windfalls and shortfalls can explain a substantial proportion of changes in the euro area cyclically adjusted budget balance over the period 1999-2007. Since these unexplained revenue changes have exhibited a largely cyclical character and might therefore be viewed as partly temporary, this highlights the importance of a careful interpretation of fiscal indicators adjusted for the economic cycle. Except in a small number of cases, the results do not change significantly when alternative tax base proxies are used, suggesting that the potential for improving existing indicators by a better matching of taxes to their bases is likely to be limited.
