I assume that you are seeking data which is available without charge. That is the snag. Also I assume that you want more than just coverage of EU countries, since Eurostat has a lot of macroeconomic data for EU countries. Both the World Bank (worldbank.org) and the IMF (imf.org) maintain quite large databases that cover macroeconomic data for 150+ countries going back to 1960 or thereabouts. Probably, the primary one for macroeconomic and monetary data is International Financial Statistics from the IMF. However, they ask for payment for full access to their databases, though the charges are discounted for academic users and for developing countries. In the recent past Poland would have qualified as a developing country, but I don't know the current situation. You could contact the local offices in Warsaw of the two organisations to see whether they have some local arrangement. On a more restricted basis the IMF publishes a dataset linked to its World Economic Outlook which appears in Spring and Autumn. This goes back to 1980 for a large collection of countries and contains basic macro data but not monetary statistics. Other organisations - e.g. the Asian Development Bank for Asia, etc - publish compilations of statistics on a regional basis. Similarly, the OECD (oecd.org) has a large database on OECD and some other countries, but again it asks for payment for anything beyond restricted access. Finally, you can look at what is available from the UN's Statistical Office (unstats.un.org). It has reasonable national accounts data - albeit somewhat out of date - but it does not compile monetary statistics. Regards Gordon Hughes
