2.2 The nature of sub-central fiscal autonomy
From Figure 1 we can immediately see that, despite a fair degree of cross-country
heterogeneity, sub-central governments tend to play an important role in the conduct of fiscal
policy. On average across the 15 countries, over a third of total fiscal expenditure (35.1%) and
a quarter of revenues (25.6%) are assigned (i.e. under the control of) sub-central governments.
The figure also allows us to see the relative size of fiscal imbalances. The vertical distance
between each point and the 45o line shows how dependent the country’s sub-central tier of
government is on grants from the central tier.

Figure 2 breaks down expenditure into a number of its key components and shows that sub-
central authorities undertake a sizeable proportion of most categories of general government
expenditure. The existing literature has focused on general government data and has
emphasised the importance of control over the government wage bill. It is therefore of
particular interest to note that, on average, some 61% of the general government wage bill is
accounted for by expenditure at the sub-central level.
