Figure 7.9 [zie afbeelding bij deze post] groups annual observations in four categories according to the share of government spending in GDP during that year. Both samples show a negative relationship between government size and growth, though the reduction in growth as government becomes bigger is far more pronounced in Europe, particularly when government size exceeds 40 percent of GDP. we provide new econometric evidence on the impact of government size on growth using a panel of advanced and emerging economies since 1995. As estimates can be biased due to problems of omitted variables, endogeneity, or measurement errors, it is necessary to rely on a broad range of estimators. They suggest that a 10 percentage point increase in initial government spending as a share of GDP in Europe is associated with a reduction in annual real per capita GDP growth of around 0.60.9 percentage points a year (table A7.2). The estimates are roughly in line with those from panel regressions on advanced economies in the EU15 and OECD countries for periods from 1960 or 1970 to 1995 or 2005 (Bergh and Henrekson 2010 and 2011).
Governments are big in Europe mainly due to high social transfers, and big governments are a drag on growth. The question is whether this is because of high social transfers? The answer seems to be that it is. The regression results for Europe, using the same approach as outlined earlier, show a consistently negative effect of social transfers on growth, even though the coefficients vary in size and significance (table A7.4). The result is confirmed through BACE regressions. High social transfers might well be the negative link from government size to growth in Europe.
