This study estimates comparable series of capital stocks for 121 NUTS2 regions in nine European countries for the period 1995-2007 using the Perpetual Inventory Method (PIM). The capital stock data for each region is disaggregated into six major sectors: agriculture and fisheries, industry, construction, productive market services, real estate, financial and other services and non market services. The estimation is mainly based on the regional Gross Fixed Capital Formation (GFCF) data series from EUROSTAT and the level and time span of depreciation rates are assumed to be different across sectors, but the same for all the regions and countries in each sector or industry. We also discuss the robustness of the estimates and analyse their sensitivity to pre-established assumptions. In order to do so, the BD.MORES database is used as a reference, together with information from the AMECO, National Statistical Offices and EU-KLEMS databases for countries.

Key words: capital stock, NUTS2, estimation.
