Efficient AllocationChapter 23, Ecological Economics, Daly & Farley

Economists suggest we find monetary values for these goods and then use the market to efficiently allocate them.

Controversy over whether establishing monetary values is appropriate or meaningful.

Pricing & Valuing Nonmarket Goods & Services

Diamonds-water paradox In the past ecosystem goods/services were

so abundant that an extra unit had no appreciable value.

As we approach ecological thresholds the values will increase rapidly.

Unlike normal market good ecosystem values would have to be continuously recalculated and fed back into the market system at a great expense of time and money.

Recalculating Marginal Values

Lack of knowledge of ecosystem function Lack of familiarity with valuing nonmarket

goods Example, the contingent valuation method

creates a hypothetical market by asking people what they would be willing to pay for a given nonmarket good/service.

Problems, Ignorance of all the goods and services provided by healthy ecosystems and people may not respond truthfully.

Uncertainty, Ignorance, & Unfamiliarity

Market Price Method Productivity Method Hedonic Pricing Method Travel Cost Method Damage Cost Avoided , Replacement Cost,

and Substitute Cost Methods Contingent Valuation Method Contingent Choice Method Benefit Transfer Method

Methodologies for Monetary Valuations

Most ecosystem goods & services can provide benefits in the future

Economists generally look to discounting Ignore the ethical decisions of

intergenerational distribution Economists argue it is a question of efficient

allocation, not distribution. Should the future have a right to resources

and if so how do we determine/enforce this?

Time, Distribution, & Valuation

We are constantly forced to make decisions between market and nonmarket goods◦ More forests or more strip malls?◦ The differences often make comparisons not only impossible

but also undesirable◦ Putting dollar values on everything does not make decision

more objective, but obscures the ethical decisions required to make “objective” valuations.

Ecological Economics, rather than trying to find the correct price for everything, espouses that we should act on the knowledge that zero is the wrong price and try to better understand that there is significant (often infinite) value even if we cannot precisely quantify it.

Market vs. Nonmarket Values

Buyer or seller has more information Car sale – Owner knows the state of the car,

the buyer does not Buyer will have a lower price to adjust for risk

than the seller is willing to accept Daly & Farley provide a few ideas, but

“welcome new and better ideas for addressing the market failures associated with advertising”.◦ Tax Advertising◦ Full disclosure advertising

Asymmetric Information Flows

Direct Subsidy◦ Compensate the private sector for its provision of

positive externalities Tax Relief

◦ Decrease in land taxes for erosion reduction◦ Tax breaks for businesses investing in personnel

training Subsidized Credit

◦ If people under-invest in activities with positive externalities, lower interest payments would stimulate greater investment.

Subsidies for Nonmarket Goods

Governments could make interest free loans or grants to activities that best promote the public good, including the provision of nonmarket goods

This could help in the macro-allocation of resource towards nonmarket goods

It could also lead to a financial system whose viability is not based on unending growth.

Using Seigniorage

Ecosystems provide services at local, regional, & global levels

Causes of degradation are often local while impacts are local, regional, & global

Policy making is primarily local and national Scale causes serious problems with

regulating and monitoring Individuals get the benefits, we all share the

negative impacts. Brazil is making progress on this matter.

Spatial Aspects of Nonmarket Goods

Spatial Aspects of Nonmarket Goods

Individual nations are unlikely to pay for the degradation to ecosystems they cause.

We all benefit, so probably we should all pay, but how?

Presently, most countries are free riders Beneficiary pays principle

Find a way for more developed countries who benefit from ecosystem services to reimburse lesser developed countries for keeping those services viable.

This is easier said then done…

International Policies

International Subsidies for Ecosystem Preservation◦ International Pigouvian subsidy◦ ICMS ecologico◦ National Pigouvian tax paired with an

international subsidy Must deal with issues of who to pay and the

possibility of people taking up a behavior just to get in on the subsidy

International Policies

Typically, allocative efficiency is achieved when we put scarce resources to the use the yields the most monetary values

Ignore diminishing marginal utility of wealth and the potential gains of redistribution.

Goal of economics is not to maximize production, but to provide service.

Production of services from manmade capital requires sacrifice of services from natural capital.

Redefining Efficiency

An appropriate measure of efficiency is the ratio of services gained from manmade capital stock (MMK) to the services sacrificed from the natural capital stock (NK)

Efficiency/ Durability3. Growth Efficiency4. Increased by creating

more natural capital stock or sacrificing fewer ecosystem services

Captures the tradeoffs between services gained and services lost (left hand side)

Uneconomic growth invariably reduces efficiency
