On belief systems, institutional change and (non)revolution....
Don't forget that institutional change is typically incremental rather than a major reversal of direction overnight. So small changes at the margin can lead to dramatic and unpredicted changes further down the line.
From North et al - 'Order, disorder and economic change' in
Governing for Prosperity:
The place to begin is the beliefs held by the members of society, because it is the beliefs which translate into the institutions which shape performance. Shared mental models reflecting a common belief system will translate into a set of institutions broadly conceived to be legitimate. Diverse and conflicting beliefs usually are derived from wide disparities in the experiences of members of a society (resulting from differences in wealth, social structure, race, ethnic backgrounds) and are exacerbated by the failure to define and enforce universalistic political and economic rules that aplly to all members of that society.
Whether the change is incremental or revolutionary, the result is typically to produce some consequences that are unanticipated. This is so because people's perceptions of reality are faulty; the belief system produces an "incorrect" model of the issues; and the policy instruments available to the players are very blunt instruments to achieve the desried objectives. Let us explore each of these in turn.
A complete understanding of reality would entail not only information about all the relevant aspects of the society but an understanding of how it all is put together. As Hayek pointed out many times, such knowledge is beyond human capacity.
The belief systems that society develops can and sometimes do capture sufficient portions of that "reality" to provide useful and predictable results. But frequently they fail to incorporate fundamental aspects of reality, particularly involving circumstances people rarely face. The rise and demise of communism provides only the most recent illustration.
The policy instruments available to the players are changes in the formal rules (constitutions, laws, regulations), but it is the combination of formal rules, informal norms, and their enforcement that constitute the institutional matrix that shapes performance. Policy makers have no control, at least in the short run, over informal norms and only very imperfect control over enforcement of both formal rules and the informal norms. In consequence, policies - such as privatization in Russia - often produce results different from those anticipated.
Finally, we come back to path dependence. It is a powerful phenomenon, resulting from a range of constraints imposed on the players. Because existing organizations (and their entrepeneurs) owe thier survival to the existing institutional matrix, they tend to oppose fundamental institutional change. Equally important is the existing belief system that defines the perceptions of the actors with respect to avenues of legitimate change. Attempts at revolutionary action, for example, alter only the formal rules, not the informal norms, and therefore usually make such change less revolutionary than its supporters envision.
Creating consensual order (as opposed to authoritarian order) requires building shared belief systems which underpin certain institutions - e.g. a constitution of citizens rights, a stable democracy, a thriving economy etc. These institutions must be seen by the masses as both legitimate and appropriate. And the masses must be willing to react against the government is it threatens to take them away.
But, North et al. argue that, in most societies, different belief systems and therefore different conceptions of what comprise fundamental rights and legitimate ends of the state coexist. Authoritarian rulers can exploit these assymetries rewarding their constituents while exploiting other citizens. Thus,
Because of the difficulties in creating the basis for consensual rights, the authoritarian basis of political order is more natural than the consensual basis.
Pretty cynical and depressing stuff...
