Examples are many, in both rich and poor countries, of devolution leading to better decisions, from the point of view of efficiency as well as equity. Technological changes have now made it administratively somewhat easier for lower levels of government to handle certain tasks. Politically, the arena of local democratic contestation and governance is also a good training ground for future democratic leaders at the national level. And, in a world of rampant ethnic conflicts and separatist movements, devolution of power can diffuse social and political tensions and ensure local cultural and political autonomy.
But liberals should also beware of communitarian romanticism. Compared to central entities where many rival groups contend, small local community institutions may be more susceptible to capture by local overlords, oligarchs and majoritarian tyrants — think of white supremacists in the localities of US South, the tyranny of dominant castes in Indian villages, or mafia capture of local institutions in Sicily. In all these cases outside intervention has been necessary to relieve institutionalised systems of local oppression. In India, during the freedom struggle, important social thinkers like Gandhi and Tagore had emphasised the centrality of the village community, but Ambedkar, the leader of a marginalised oppressed group (who later as one of the founding fathers of the Indian Constitution tried to do something about that oppression through liberal-constitutional means), used to call the Indian village community a ‘cesspool, …a den of ignorance, narrow-mindedness and communalism’. When there is such ‘community failure’ for the socially marginalised groups, the anonymity of the market or an intervention by the distant state with its impersonal legal procedures may be welcome.
At a somewhat less oppressive level of associational life, all of us are familiar with too much insider control in local bodies for zonal restrictions or professional licensing, not-in-my-backyard-type resistance to new projects (even liberal but expensive cities like San Francisco are, for example, divided on the issue of public housing projects), and local property tax based school financing, that work against the interests of the poor and disadvantaged. Decentralisation can thus exacerbate inter-community inequality; under devolution of power and more autonomy communities with initial advantages build on them and advance faster. Then there are related issues like externalities and spillovers where local control mechanisms are inadequate, as in the case of upstream deforestation causing flooding and soil erosion in downstream communities. Intra-community economic inequality can also have an adverse impact on trust and cooperation. For instance, in my empirical work on south Indian irrigation communities, I have found statistical evidence that across villages when land is more unequally distributed, farmers’ cooperation on resolution of water conflicts breaks down more easily.
