Environmental economics • What is it? • What does it include?
Environmental economics • What is it? • Expansion of traditional economics to include non-market values • Risk assessment and cost-benefit analyses • What does it include? • Includes non-market values (esthetic, cultural, emotional), ecosystem services, environmental health and safety concerns, sustainable development, carbon accounting etc.
“Free Market” economics • Market provides mechanism to allocate resources to best (highest valued) uses • Prices provide information about values • Ideally, resources are allocated in a way that optimizes efficiency • However, does not always optomize for environmental resources: • Information is incomplete, some resources have no market, future discounting devalues conservation, “tragedy of the commons”
Valuing environmental resources • What are environmental (non-market) values?
Valuing environmental resources • What are some environmental values? • Health, wellbeing • Intrinsic values of wilderness and wildlife • “Ecosystem services” • “natural capital” • Future potential values (e.g. new discoveries)
How to place values on resources? • $ value on non-direct costs and benefits • Estimate cost to use technology to perform actions conducted by ecosystems (e.g. water or air filtration) • Estimate costs of amelioration (e.g. healthcare costs VS prevention of environmental pollution) • Surveys: ask people what things are worth (“what would you pay to maintain ecosystem X”)

Non-market values in range and forest ecosystems • What are some values that might apply? How would you account for them?
“Market Failure” caused by non-market resources • Market failure= non-optimal allocation of resources. • How can it be remedied? Account for non-monetary values, or bypass market mechanism and impose policy.
Can non-monetary values be accounted for by traditional economics?
Can non-monetary values be accounted for by traditional economics? • Yes: we can translate all values into common metric ($) and can assess using free-market economics
Can non-monetary values be accounted for by traditional economics? • No: some things have no $ value. Some decisions (environmental and social policy) must be made outside the realm of the market • Yes: we can translate all values into common metric ($) and can assess using free-market economics
Case study: modeling costs, management, and vegetation • Simulation model predicting outcomes of various management strategies • non-market values (e.g. environment values) must be considered external to the model to make management decisions
