Continuing with excerpts from great books on environmental and energy issues (see last week’s posts here), below is an excerpt from Mark Pennington’s brilliant new book Robust Political Economy. “Robust” political institutions are, according to Pennington, those “institutions that perform best given that people 1) have limited knowledge and 2) are prone to self-interested behavior.” He argues the case that market institutions are better suited to deal with these realities than governments. In this passage, he applies these two criteria to environmental protection.

Robust Political Economy was released in 2011
Classical liberalism does not question the view that environmental problems arise when private actors are unaccountable for their actions. What it does question is the supposition that political intervention, whether of the ‘command and control’ or ‘price-based’ variety, is the best way of ‘internalising’ the relevant externalities. There are two dimensions to this account which reflect the focus on the conditions required for a robust political economy of institutions and decisions.
The first line of analysis draws on the Hayekian understanding of the knowledge problem. Seen from this perspective, neo-classical approaches to environmental policy repeat the socialist calculation error by assuming that the knowledge necessary to correct for ‘market failures’ is somehow ‘given’ to policy-makers. In an environmental context the assumption is that trade-offs between environmental and other objectives are known and fixed.
Viewed through the Hayekian lens both command and control and price-based policy mechanisms are variations of central planning and may be inappropriate because the primary environmental problem is typically not one of giving people the right incentives to act on the basis of known environmental values, but of discovering what the relevant values are. Knowledge of these values is fundamentally dispersed throughout society and evolves in light of the changing ideas of individuals and organisations as they interact with each other and the natural world.

When I began to work on population studies, I aimed to help the world contain its “exploding” population, which I believed to be one of the two main threats to humankind (war being the other)….
