Regionale Wachstumseffekte der GRW-Förderung?: Eine räumlich-ökonometrische Analyse auf Basis deutscher Arbeitsmarktregionen

This paper provides an analysis of the impact of the German “Joint Task for the Improve-ment of Regional Economic Structures” (GRW) on labour productivity growth of 225 German labour market regions for the period 1994 to 2006. The empirical regression approach builds on a “Barro-type” growth equation, where a special focus is given to the policy instrument as additional right hand side regressor. The results show that for different model specifications the direct effect of the regional policy instrument on labour productivity growth remains statistically significant and positive for almost two thirds of the supported labour markets. In order to check for the robustness of the results we also augment the standard regression approach to the field of spatial econometrics. Here the results for the Spatial Lag model show that we observe a strong positive spatial spillover effect for productivity growth among neighbouring regions. If we additionally include further spatial lags of the right hand side regressors in the growth equation, the estimated coefficients for the resulting Spatial Durbin and Spatial Durbin Error model indicate that there is a negative spillover effect from the GRW policy on neighbouring regions. This effect remains stable, if we add further spatial lags of other explanatory variables. The indirect distorting effect of the GRW programme yields to the result that only for about 45% of supported regions a positive overall effect was found (with an initial income level up to 73% of the non-funded West German labour markets)

Measurement of the Charged Multiplicities in b, c and Light Quark Events from Z0 Decays

Average charged multiplicities have been measured separately in $b$, $c$ and light quark ($u,d,s$) events from $Z^0$ decays measured in the SLD experiment. Impact parameters of charged tracks were used to select enriched samples of $b$ and light quark events, and reconstructed charmed mesons were used to select $c$ quark events. We measured the charged multiplicities: $\bar{n}_{uds} = 20.21 \pm 0.10 (\rm{stat.})\pm 0.22(\rm{syst.})$, $\bar{n}_{c} = 21.28 \pm 0.46(\rm{stat.}) ^{+0.41}_{-0.36}(\rm{syst.})$ $\bar{n}_{b} = 23.14 \pm 0.10(\rm{stat.}) ^{+0.38}_{-0.37}(\rm{syst.})$, from which we derived the differences between the total average charged multiplicities of $c$ or $b$ quark events and light quark events: $\Delta \bar{n}_c = 1.07 \pm 0.47(\rm{stat.})^{+0.36}_{-0.30}(\rm{syst.})$ and $\Delta \bar{n}_b = 2.93 \pm 0.14(\rm{stat.})^{+0.30}_{-0.29}(\rm{syst.})$. We compared these measurements with those at lower center-of-mass energies and with perturbative QCD predictions. These combined results are in agreement with the QCD expectations and disfavor the hypothesis of flavor-independent fragmentation.Comment: 19 pages LaTex, 4 EPS figures, to appear in Physics Letters
