Can capitalism be ‘green’?
The beneficial aspects of property rights
Private property refers to the right to use, control, and obtain benefits from a resource, good, or service. This includes the right to exclusive use, the right to transfer property to others, and legal enforcement against invaders. Property in this context can refer to buildings, land in agricultural use, forestry and fishing grounds. Property rights yield three key benefits.
Property rights incentivise private owners to use resources in ways that benefit others. In markets, a profit indicates that property owners have used their resources in a manner which is pleasing to consumers.
Secondly, private owners have an incentive to care for and manage their property. This is because property rights internalise the benefits and costs of the behaviour of owners. If property owners exercise care in the upkeep of their property, they benefit in terms of the increased value of the resource. Likewise, if owners choose to allow their property to fall into disrepair, they incur the cost through the decreased value of the property.
Finally, property owners have an incentive to consider the long-term consequences of their actions. Owners have the right to future cash-flows associated with their property. This incentivises owners to ensure that their resources are used sustainably. For example, the owner of a fishing ground will wish to keep stocks buoyant because that will ensure that the profitability of the resource in the long term is maximised. This, in turn, is reflected in the value of the resource at any given time. If nobody owns the fishing ground, trawler owners will tend to over-fish.
Property rights and the environment
Once the benefits of property rights are appreciated, it becomes clear that well-defined property rights are crucial to maintaining and improving the environment.
Consider the incentives for property owners to care for what they own and to consider the long-term consequences of their actions. This reality is at odds with how many people view capitalism which is often characterised as the drive for immediate profits with no regard for the long-term consequences. The example of fishing grounds has already been mentioned about which there is ample evidence. There are other examples of natural experiments which allow for a test of the two competing views of property rights and the environment. There has long been a concern about the declining elephant population in Africa due to the poaching for ivory. In Africa, there is variation in ownership rights over the elephant population. In some areas elephants can be privately owned while in others they are communal property. An empirical study looking at the factors influencing the elephant population in Africa found that “countries with property rights systems or community wildlife programs [which create residual claimants over the well-being of the elephants] have more rapid elephant population growth rates than do those countries that do not.”
These findings make perfect sense when considered in light of the incentives created by property rights. Clearly defined property rights incentivise owners to care for their property, which is reflected in faster growth of the elephant population in areas which allow for private ownership. The lack of private ownership, in contrast, leads to the tragedy of the commons whereby a communal-resource system leads to overuse, as each individual considers their own costs and benefits while neglecting the broader implications of their actions. Indeed, where there are no ownership rights in elephants, they are just regarded as a pest (they only bring costs to farmers) and therefore they are shot.
Property rights also allow non-profit organisations to engage in environmental conservation. For example, among other programmes, the Sierra Club often raises funds to purchase tracts of land which it then maintains or turns over to other entities that conserve the land. This illustrates the range of opportunities that private ownership offers for environmental conservation and improvement.
More generally, the innovation that arises in a free economy yields numerous benefits. It leads to less waste because there is an incentive to economise on resource use to cut the cost of production. Consider, for example, the traditional drinks can which is made from aluminum. The first generation of cans, introduced over a half-century ago, weighed three ounces each; current cans weigh approximately one ounce. This change was due to innovations in the production techniques which allowed producers to use less aluminum while producing a stronger can.
There are also significant long-term benefits to innovation. Over time, there have been advances in sanitation and medicine which have reduced, and often outright eliminated, many of the pollutants which plagued people in the past. These long-term benefits are typically neglected in discussions of the environment even though the improvements in standards of living due to innovation and increases in wealth are truly staggering.
The implications for the environment
Appreciating the benefits of property rights is crucial for understanding the relationship between capitalism and the environment. Contrary to popular opinion, markets and the environment are not at odds with one another. In stark contrast, well-defined property rights are important not just for maintaining the environment, but also for improving it.
One key implication is that, when discussing environmental issues, it is crucial to start by thinking about the current property rights arrangements, or lack thereof. The absence of property rights leads to environmental harms, since private actors lack the incentive to take into account the full cost of their behaviours. Many environmental problems can be addressed by defining or clarifying property rights.
It is also important to remember that improvements in the environment do not occur in a vacuum. General economic progress and growth are positively correlated with better environmental quality. As the environmental economist Terry Anderson writes, “[t]he correlation between environmental quality and economic growth is incontrovertible. Comparing the World Bank’s environmental sustainability index with gross domestic product per capita in 117 nations shows that richer countries sustain environmental quality better than poorer countries do. Indeed, every systematic study of environmental indicators shows that the environment improves as incomes rise.” There are theoretical reasons to believe that the direction of causation runs from economic growth to improved environmental quality.
Moreover, greater wealth affords citizens the opportunity to care more about the environment. It is precisely because citizens in wealthy countries do not have to worry about the diseases and other pollutants that existed not long ago that they can, instead, worry about current environmental concerns. People who are worried about where their next meal is coming from, or who must be worried about dying from malaria, are not in a position to be concerned about endangered species or potentially rising water levels.
Contrary to popular beliefs, the best environmental outcomes can only be secured through well-defined and well-enforced private property rights. Just as individuals have much to gain from capitalism, so too does the environment.
