Economics and Conservation Tradeoffs

A streamside decision

A watershed partnership wants landowners to restore riparian buffers: vegetated strips beside streams.

Buffers may improve water quality and wildlife habitat. Landowners bear installation, maintenance, and foregone agricultural income.

Who should pay for benefits that extend beyond the property?

What you should be able to explain

• Connect earlier social values to economic value without treating them as identical.
• Explain how rights, costs, and incentives affect conservation.
• Distinguish price, nonmarket value, and who gains or pays.
• Compare alternatives and identify evidence that could change a recommendation.

The questions carry forward

Module 01: Which outcomes and actions do people consider desirable?

Module 02: Who benefits from public trust resources, now and in the future?

Module 04: How do values and evidence inform a decision?

Module 09: What benefits, costs, and tradeoffs follow from each choice?

Social values and economic value

Values help explain why an outcome matters. Economic valuation examines benefits and tradeoffs for a particular change.

From broad values to a specific choice

The same concern can produce different choices

Two landowners may both care about the stream.

One can afford to remove a strip from production. The other depends on that income and cannot cover installation.

Willingness to pay reflects preferences and ability to pay. A smaller dollar amount does not establish less concern.

An interview about stewardship and a valuation survey answer different questions.

Scarcity makes every choice a tradeoff

Economics examines how people allocate limited resources.

A buffer uses land, labor, time, and money that could serve another purpose.

Opportunity cost: the value of the next-best alternative given up. For a landowner, that may include foregone agricultural income.

A payment changes who pays; it does not remove the tradeoff.

How markets coordinate choices

Price and benefit are different quantities

Consumer surplus is willingness to pay minus the price actually paid.

Illustration: someone would pay $30 for a visit and pays a $10 fee. The surplus is $20, holding other costs aside.

The fee records a payment. It does not record the entire benefit of the visit.

Likewise, recreation spending alone misses benefits to users and nonusers.

Economic value includes nonmarket benefits

Market transactions: crops, equipment, labor, or a paid recreation service.

Nonmarket benefits: an enjoyable wildlife encounter, cleaner water, or knowing habitat persists without a direct sale of that benefit.

One resource can provide both. Market/nonmarket describes exchange; use/non-use describes how the benefit arises.

Use values: experience and ecological support

Direct use: fishing, hunting, wildlife viewing, or hiking.

Indirect use: ecological functions that support other benefits, such as nursery habitat supporting a fishery or wetlands reducing flood damage.

For our case, identify the ecological change, the benefit, and the people receiving it. Their magnitude still needs evidence.

Value can extend beyond current use

• Option: keeping the possibility of using the resource yourself later.
• Bequest: conserving it for future generations.
• Existence: valuing its continued existence even if you never use it.

A concern for future generations can motivate bequest value. A visitor count will not reveal that full benefit.

Value the change the decision would cause

Total economic value includes direct, indirect, option, bequest, and existence benefits.

Marginal value concerns an additional unit or increment.

The board needs the value of additional restoration compared with no new program, not the value of the entire watershed.

The next restored parcel need not provide the same benefit as the first.

Property rights shape the available choices

Rights may include access, use, management, exclusion, and transfer.

A landowner’s ability to manage a buffer is different from an angler’s right to enter that property.

A partnership’s ability to fund restoration is different from authority to require it.

Rights affect incentives, investment, and whose opportunities are protected.

Two questions distinguish four kinds of goods

Excludability: can access be restricted? Rivalry: does one person’s use leave less for others?

Private incentives can miss public consequences

Negative externality: a decision imposes an uncompensated cost on others, such as downstream damage from runoff.

Positive externality: a decision benefits others without fully rewarding the provider, such as habitat benefits from a buffer.

Social costs and benefits include effects beyond the decision-maker. Here “social” means society-wide accounting.

A policy can change incentives in either direction

Market failure: unpriced harm encourages too much damaging activity, or unrewarded public benefits discourage conservation.

Policy failure: rules or subsidies create unintended harm.

A subsidy that lowers production costs may encourage expansion into habitat. A conservation payment may encourage restoration.

Ask what behavior the rule actually rewards.

Why a cost-share offer might help

The landowner pays restoration costs while some benefits reach other people.

Cost-share reimburses part of eligible practice costs. Payments for ecosystem services pay for defined environmental services.

Both can change the incentive. Results still depend on participation, placement, maintenance, and whether the expected service occurs.

Pair check: values, benefits, and incentives

Consider this illustrative statement:

“I want my grandchildren to have a healthy stream, but I cannot afford to take productive land out of use.”

1. Name the social value and a related economic value.
2. Identify the constraint and a cost-share incentive.
3. Explain why declining to enroll would not prove a lack of concern.

Revealed preference: learn from actual choices

Travel cost: relate visits to travel expenses, fees, and time to infer recreation demand and benefits.

Hedonic pricing: isolate how environmental conditions relate to property prices while accounting for other features.

Observed choices help estimate use benefits. They miss people who value conservation but never visit or buy property there.

Stated preference: ask about a defined change

Contingent valuation: ask whether people would pay a specified amount for a specified outcome.

Choice experiment: compare alternatives that vary in outcomes and cost.

These can include nonusers and future-oriented benefits. Credible scenarios, payment terms, and who is asked affect the result.

Benefit transfer: use evidence from another setting

Apply a previous valuation study to the policy setting.

Value transfer: adapt an existing estimate. Function transfer: use a model that accounts for relevant differences.

Check the environmental change, affected population, substitutes, units, and time period. A convenient number is not automatically a suitable one.

Choose the method for the missing benefit

Recreation benefit: travel-cost evidence may help.

Existence or bequest benefit among nonvisitors: a carefully designed stated-preference study may help.

Landowner enrollment: ask about costs and participation conditions.

The best next evidence may concern feasibility rather than valuation.

Benefit-cost analysis compares changes

1. Define the baseline, affected population, and time period.
2. Identify additional costs and benefits, including nonmarket effects.
3. Estimate those effects and put different years on a common basis.
4. Compare net benefits and report uncertainty and omitted effects.

Net benefit = benefits − costs. A financial budget alone does not provide the full comparison.

Timing and uncertainty can change the result

Installation costs may occur now; habitat benefits may arrive later.

Discounting expresses effects in different years as present values. A higher discount rate gives less weight to later benefits and costs.

Compare plausible assumptions about costs, outcomes, timing, and durability. Report when the preferred alternative changes.

A positive total does not settle fairness

Efficiency: do the added benefits justify the resource costs?

Distribution: who gains, who pays, and who is missing?

An alternative can have positive net benefits while imposing serious burdens on a particular group.

Recall public trust, inclusion, and governance: the decision also needs legitimate authority and a fair process.

Changing the payer does not erase the cost

Under A, the partnership and enrolled landowner share installation costs.

Under B, the landowner pays installation costs; implementation still requires administration and enforcement.

For a society-wide account, record installation resources once and track how payment responsibilities shift.

Also identify maintenance, foregone income, and unequal ability to pay.

Compare the two restoration alternatives

A: voluntary cost-share

Participation depends on whether the offer works for landowners and whether needed parcels enroll.

B: a buffer requirement

Coverage depends on confirmed authority, implementation, and compliance.

With a partner: identify one likely tradeoff, one affected public, and the missing evidence that matters most to your choice.

Turn an information gap into a decision rule

Name what to learn, how to learn it, and whose information is needed.

Then state:

If we found ___, we would revise ___ because ___.

For example, poor enrollment on priority parcels would be a reason to reconsider an offer or the preferred alternative.

Bring the value connection back to the decision

Social values help define desirable outcomes and responsibilities.

Economic values describe benefits and tradeoffs for particular changes, including benefits without a market price.

A management decision combines that evidence with distribution, authority, and what affected publics consider acceptable.

Prepare for Friday, October 23

Read the Case Brief and find your preassigned group and role.

Submit the role record and four sections: diagnosis; value and distribution; recommendation; evidence and revision.

Due before 10:50 a.m. Shared response: 80 points. Every present member completes the private Group Check: 20 points.

Identify the case evidence and chapter concept. Exact box or section numbers are not required.

Reference: a race to harvest

A shared catch limit may encourage people to harvest before others do.

Secure harvest shares can reduce that race and encourage longer-term planning.

But transfers can concentrate fishing rights. Ownership caps, community provisions, and entry protections address different distribution concerns.

Changing incentives and protecting communities require attention to design.

Reference: accounting for an external cost

The unpriced harm creates a gap between private cost and social cost.
