Is East Germany Catching Up? A Time Series Perspective
IWH Discussion Papers,
This paper assesses whether the economy of East Germany is catching up with the
West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as unemployment rates, wage rates, and production levels in the manufacturingsector. In contrast to existing studies of convergence between regions of reunified Germany, our approach is purely based upon the time series dimension and is thus directly focused on the catching up process in East Germany as a region. Our testing setup includes standard ADF unit root tests as well as unit root tests that endogenously allow for a break in the deterministic component of the process. In our analysis, we find evidence of catching up for East Germany for most of the indicators. However, convergence speed is slow, and thus it can be expected that the catching up process will take further decades until the regional gap is closed.
Regional Growth and Finance in Europe: Is there a Quality Effect of Bank Efficiency?
Journal of Banking & Finance,
In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures of financial institutions. Contrary to the usual quantitative proxies of financial development, the quality of financial institutions is measured in this study as the relative ability of banks to intermediate funds. An improvement in bank efficiency spurs five times more regional growth then an identical increase in credit does. More credit provided by efficient banks exerts an independent growth effect in addition to direct quantity and quality channel effects.
Effects of the promotion of investment in East Germany
IWH Discussion Papers,
Investment in East Germany is heavily subsidized. Econometric estimates based on a treatment approach show that the level of investment is significantly higher in firms being supported by state aid. Nevertheless, capital productivity is lower in East Germany, indicating a misallocation of capital. Additionally, there are negative effects in West Germany due to negative crowding-out effects. Therefore state aid in East Germany should be reduced in the medium run.
