drawbacks in the political <strong>and</strong> legislative processes of centralised systems that may<br />

induce inequity, uncertainty, or excessive public spending.<br />

In Tommasi <strong>and</strong> Weinschelbaum (1999), the advantages of centralised decision<br />

making (internalisation of externalities) are compared to those of decentralised decision<br />

making (increased control of agents by the citizens through lower information<br />

asymmetries, less free-riding <strong>and</strong> easier coordination). In addition, decentralisation may<br />

have the advantage of encouraging competition if citizens “vote with their feet” (Tiebout<br />

1956).<br />

Oates in his Fiscal Federalism (1972, p.13) summarises the economic desirable<br />

characteristics a decentralised public sector possesses.<br />

First, it provides a means by which the levels of consumption of some public goods can<br />

be tailored to the preferences of subsets of the society. In this way, economic efficiency<br />

is enhanced by providing an allocation of resources that is more responsive to the tastes<br />

of consumers. Second, by promoting increased innovations over time <strong>and</strong> by providing<br />

competitive pressures to induce local governments to adopt the most efficient<br />

techniques of production, decentralization may increase both static <strong>and</strong> dynamic<br />

efficiency in the production of public goods. Third, a system of local government may<br />

provide an institutional setting that promotes better public decision-making by<br />

compelling a more explicit recognition of the costs of public programs.<br />

Oates concludes (1972, p.19) that mix of centralised <strong>and</strong> decentralised forms of the<br />

government is the central theoretical problem of the subject of fiscal federalism, or in his<br />

own words “This [...] is the central theoretical problem of the subject of fiscal federalism:<br />

the determination of the optimal structure of the public sector in terms of the assignment<br />

of decision-making responsibility for specified functions to representatives of the<br />

interests of the proper geographical subsets of the society.” In the final analysis of this<br />

issue the selection of the proper level of government to provide a particular good or<br />

service is not an easy problem; there are typically a number of variables that figure in this<br />

decision, <strong>and</strong> in most instances, some form of trade off between welfare gains <strong>and</strong> losses<br />

is involved.<br />

<strong>The</strong> principle of subsidiarity suggests that economic performances of the<br />

governments will be more responsive to consumer dem<strong>and</strong>s <strong>and</strong> to cost cutting<br />

pressures (i.e. more efficient) if services are provided by the lowest level of government<br />

possible. While foreign policy, defence, immigration, <strong>and</strong> international trade can be
