The sluggish convergence between East and West Germany and the persistent productivity deficit of the East Germany economy are the motivation of a large number of studies and analyses. Public physical capital and human capital play a major role therein. However, there are no appropriate time series to verify the hypotheses which are discussed in the literature in empirical studies. Therefore, in this thesis public and private physical capital as well as human capital will be estimated for East and West Germany. The newly constructed data are then used to derive more exact estimates of total factor productivity in both regions.
