Economics and the Environment Environmental And Resource Economics Applies The Tools Of Economics To The Subject Matter Of Environmental And Resource Issues Lecture in Movie OVERVIEW 3 The Power of Markets 02 Markets are very powerful ways of allocating goods. Market signals, usually prices, affect what people produce and buy, as well as how those goods are produced; they can have strong effects on the environment, both for good and for ill. Env. and Resource Economics Problems with Markets Conflicts arise over the use of environmental goods because there is not enough available for people to have them in their pristine state and also to use them for production or waste disposal.. Markets often fail for environmental goods, as well as other goods. Understanding that markets fail contributes greatly to understanding the role of economic analysis in public policy; understanding how they fail gives further insight into environmental problems. Approaches to Env. Policy The advantage these approaches are that, because of their incentives and flexibility, they can achieve any desired reduction in pollution at a lower cost to society. Scope of Env. Economics 05 Natural Resources Natural resources are materials and substances that occur naturally and can be used for economic gain. They include minerals, forests, fertile land, and water. Some natural resources, such as soil and water, are essential for the existence of life. The scope of environmental studies is very wide and it deals with many areas like i) Conservation of natural resources, ii) ecological aspects, iii) pollution of the surrounding natural resources, iv) controlling the pollution, v) social issues connected to it, and vi) impacts of human population on the environment. What is Environmental Economics? Economics is the study of the allocation of scarce goods– Including Environmental The Environment and Economy Are Linked Economies Receive Inputs From the Environment – Process them for use – Discharge the wastes back into the environment Traditional Economists Ignore the Environment – Environmental economists accept that human economies exist within, and depend on, the environment Environmental and Resource Economics 01 02 03 Economics Studies the allocation of scarce resources, specially but not only through market processes Env. And resource issues arise from human interaction with natural world Env. And resource economics uses the tools of economics to analyze env. And resource issues Slide 6/ The Power of Markets 7 02 Market choices influence the natural environment, in both positive and negative ways which lead to change people behavior toward the environment 01 Markets provide people with the opportunity to make choices in response to prices. Changes in prices lead to changes in those choices Problems with Market Markets often do not exist for env. goods. This failure of markets may be the basis of conflicts over env. Goods. Markets may not work effectively for other goods and situations. A problem with one market is likely to cause difficulties in other markets connected to it. The markets are highly interconnected including the associated env. Problems.

Till MB=MC 17 “Free” markets will generate excessive pollution and overuse environmental services, hence, collective or public intervention is necessary 02 03 Valuation of nonmarket goods 04 Design of policy instruments to achieve environmental goals Approaches to Environmental Policy 18 tells consumers which brands use environmentally benign processes. . The government can issue permits to individual polluters. They may buy, sell, and trade these marketable emissions permits this provides financial incentives to reduce pollution. - Discourages undesirable activities by taxing activities and products that cause undesirable environmental impacts. - It’s a tool for policy as well as a way to fund government. Commandand-control - An approach that sets strict legal limits, and punishments . as opposed to financial incentives. - Ex. Regulate pollutants such as SO2 and NOx A government giveaway of cash or publicly owned resources used to promote a particular activity.
