2. The Ecological Economics Approach Rather than applying economic concepts to the environment, ecological economics seeks to place economic activity in the context of the biological and physical systems that support life, including all human activities.

Microeconomic and Valuation Techniques 1. Measuring external costs and benefits An external cost is a cost that a producer or a consumer imposes on another producer or consumer, outside of any market transaction between them. "External" means "outside. " Here, "outside" means outside of any buying and selling among people or firms. If there is an external cost on you, you are giving something up without receiving any agreed-upon payment. Pollution of air or water is the prime example of an external cost.

Microeconomic and Valuation Techniques 1. Measuring external costs and benefits An external benefit is a benefit that someone gains because of someone else's action, outside of any market transaction between them. Immunizations give external benefits. When you get a vaccine for a certain disease, you make it less likely that you will contract the disease. That is the internal benefit. What you also do ? is make is less likely that other people will get the disease, because they probably will not catch it from you.

Microeconomic and Valuation Techniques 1. Measuring external costs and benefits for example, estimating a money value for damage caused (Cost) by acid rain pollution. This value can then be compared to the costs of correcting the problem through pollution control technology or reduced output of polluting activities. We can internalize externalities through … Tax on the polluting activity.

Microeconomic and Valuation Techniques 2. Valuing resources and the environment as assets This involves considering inter temporal resource allocation, the choice between using a resource now or conserving it for future use. The standard economic technique to balance present and future benefits and costs is to use a discount rate. In this technique, a present benefit or cost receives a somewhat higher value than a future benefit or cost—how much higher depends on the discount rate employed and on how far into the future the comparison extends.
![Thus the discounted present value for one cash flow in one future period is Thus the discounted present value (for one cash flow in one future period) is](https://slidetodoc.com/presentation_image/5af5d8a66f76070ca8ec6030024ff0ee/image-18.jpg)
Thus the discounted present value (for one cash flow in one future period) is expressed as:
![Net Present Value NPV compares the value of a dollar today to the Net Present Value - NPV compares the value of a dollar today to the](https://slidetodoc.com/presentation_image/5af5d8a66f76070ca8ec6030024ff0ee/image-19.jpg)
Net Present Value - NPV compares the value of a dollar today to the value of that same dollar in the future, taking inflation and returns into account. If the NPV of a prospective project is positive, it should be accepted. if NPV is negative, the project should probably be rejected because cash flows will also be negative.

Microeconomic and Valuation Techniques 3. Devising appropriate property rights rules for environmental resources and establishing rules for use of common property resources and for provision of public goods. For example, a fishery may be privately owned, or it may be public with access limited by government sale of fishing licenses. Similarly, a wildlife preserve may be privately owned and managed or may be maintained as a public park.

Microeconomic and Valuation Techniques 4. Balancing economic costs and benefits through some form of cost-benefit analysis. This often involves a combination of values observable in the market, such as values of land or goods, and estimates of nonmarket values, such as natural beauty and maintenance of species diversity.
