INTRODUCTION AUG 26th · Human Development Index · IPCC (intergovernmental Panel on climate change · Wildfires in California How can economics solve environmental problems ? - economic incentives - transfer resources money from one area to another ENVIRO ECON INTRODUCTION.. WED AUG 28th , Major environmental issues ? What is economy ? How can economics help us solve these issues ? c study of allocation of scare resources Economics + Enviro · restraint ; immediate gain vs. long-term benefit · how do we encourage markets to make beneficial decisions Macroeconomics : inflation , enconomic growth enviro. Macroeconomics : water cycle , carbon system · most severe risks globally in next 10yrs > - 50 % environmental Microeconomics : resources , optimize individual action for best return enviro. Microeconomics : economic valuation , property rights rules to determine efficient allocation of natural resources + enviro. Services should enviro issues transcend economics ? ·. - can use other incentives like morals , ease of access , fashion trends ex · Preserve open land w/ high commercial development value ? enviro. Protection Policies often measured rejected for economic cost - + · What do we do for economic advantage ? - cars => gas , taxes - Al lenergy + water use) - fast Fashion Fracking - + fossil fuels -> more Stable Politically + - mining + deforestation lower $ but enviro. - justice problems · environmentally-friendly development is possible yet any kind of development will have impacts ex. Waste water treatment , thrifting , long-term sustainable energy like solar, ecotourism 1. health benefits + enviro. Protection ex reducing greenhouse gas reduces death from air pollution TWO APPROACHES TO ENVIRO. ECON FRI , AUG 30th environmental economics : mainstream ecological thought to apply economics to environment (traditional , conservative , similar to how we think of econ · diff rules for private vs. Public goods · logic on nonrenewable resources based on supply demand + traditional econ. thought · externality : a 3rd party not part of the transaction is affected from consumption of that good ecological economics : places economic activity in context of biological + ↑ hysical systems · uses concepts from natural sciences : broader · carrying capacity : size of the pop , that can be supported by the resources avaliable · human activity must be limited by enviro Carrying capacity · scale effect : something on one scale doesn't necisarily work on another INFRASTRUCTURE · buildings highways , , any alteration of enviro.

BALACE not MAXIMIZING PROFIT · technology development · cost is 2nd priority · subsidies ECONOMIC CONCEPTS EXTERNALITIES WED SEP4th , demand : percieved marginal benefit consumers obtain from consuming 1 additional Unit ex. the joy of eating burgers decreases we each burger SUPPly : Marginal cost of production ; cost of producing I more unit of a good or service benefit for max min Cost economic efficiency equilibrium. : , no externalities , max benefit to buyers and sellers EXTERNALITIES + 3NAPARTY EFFECTS · side effects of car use + production... air pollution energy production mining of materials · , , contamination , , acid rain , urban smog , freeway land use · market overestimates social benefit b/c cost of externalities not considered · assign 1 Monetary value to enviro. damages $ · value on negative externality but does not cover all side effects least · at some value => If we do not assign a value , the market will automatically assign a 0 value SOCIAL MARGINAL COST CURVE · normal private production cost + enviro. Cost = total social cost · above original market supply curve b /c now includes externality costs ↑ · use additional cost for social Marginal cost to impose taxes same thing · Pigovian tax : Polluter pays principle · portion of tax passed to consumer ↑ Price (P) and ↓ quantity (a) · L · replace negative externalities wI tax price, a need to estimate social marginal · cost soldnice & well to tax correctly for max efficiency originaland Should the government always impose a tax to counter externality ? · if you don't , there will be a loss · taxes don't effect everyone equally · not reducing negative externalities , rely on community to distribute $ ex. does not reduce car emissions if people proritize driving over cost expensive to estimate right complicated tax collection · tax + upstream tax : tax on raw materials that cost most enviro. damage ex. Fossil fuels , chemicals , etc. tax can fall disproportionaly certain income groups (ex lower income · on. households spend more $ on Fossil fuels · other regulation = fuel efficiency standards or catalytic converters POSITIVE EXTERNALITIES FRI , SEP Coth ex. Vaccines (return on investment is very high) , you planting a tree requires an investment of time money that provides air fillering benefit to everyone · something we are paying for but all of society is benefitting · should positive externalities be included in our assesment of social benefit ? · yes , to optimize + encourage a certain behavior ex. every $1 invested in proposed smog standard = $3 health benefit ex - solar Panels = reduce emissions for everyone subsidy : Payment to producer benefit = cost to incentivize production of good v -$ goes down ; produce more at lower Price c lowers When cost = benefit CONSUMER + PRODUCER SURPLUS consumer surplus : diff btw max $ bigger area benefit stability * more $ : + a consumer will pay vs. actual of product producer surplus diff btw $ firm : receives vs. Price willing to sell at · consumer + producer surplus = total market benefit for QM... market equilibrium now social equilibrium now C S.. = A P S. = B + E negative externality of QX H F G. = , , dedUCt I from A , B E , to get true market benefit CLASS ACTIVITY MON , SEP 9th SOCIAL COST - PRICE - a SUPPLY Pi P · - SUBSIDY & DEMAND Q, QUANTITY PRIVATE PROPERTY RIGHTS What type of property ownership do we have ? · public , private (owned by individual) , open access (ex. air we breath · decisions made by 1 property owner affects others in that area · Ronald Harry Coase (1960s) => Social Cost · how do we minimize social cost (no need for gov. regulation · coase theorem : if property rights are well defined + there are no transaction costs , an efficient allocation of resources will result even if externalities A wants to drain B doesn't bic will increase Wetland for $5000 earning flood risk ; lose $8000 A < B will accept will pay up anything over $5000 to $8000 · farmer B is taking on rights to As land by paying money A 9 B new crop gets A will now Pay B $10 , 000 them $20 000 , to cover cost free market environmentalism : allow the free market to handle issues of resource use+ pollution regulation 1) well defined property rights + transferable 2) efficient + competitive system for parties to exchange 3) complete set of markets so owners capture social values of use of enviro asset CONCERNS W/ PROPERTY RIGHTS 1) Food processing plant uses lake waler for operation 2) Industrial operation uses lake for waste disposal Which is causing damage vs. Suffering damage ? damages # 12 - #2 on both · lake/community only considered when public property · depends on who acquired property 1st (Senior vs. junior right Would it lead to zero uncontrolled emissions if controlled by 1 firm ? - cost of damaging or reducing emmisions eX. Firm B has initial right = damages of dumping waste into lake = cost of reducing emissions ~ cost of trapping pollution from waste stream · is it worth eliminating ALL pollutants when the cost is high & cost of industrial operation to reduce e1 to ex & equilibrium => optimal most efficient level of pollution (damages = cost) Farm B should poliule at equilibrium ; Farm A will be willing to Pay anything in C area to reduce emissions ex.

Costs c might accept any compensation they can get rather than what they deserve 5) time limits : Property rights typically limited to current generation - continuous renegotiation 6) non-human perspective not considered included PUBLIC GOODS FRI SEP 13th , · a natural area can be part of someone's private property ex. MPA , Stream in someone's land so have rights over fish , trees , etc. · yet some things remain public good - air , Scenic resource · in general , nature is public good a THE LORAX TRAGEDY OF THE COMMONS · how we our destroying our COMMON enviro. => no incentive · PPI invest in health of Public property (ex. lawns · no one owns the trees Common property resource : accesible to a group of ppl + not subject to private ownership (belongs to several communities all Monitoring + under certain set of rules) (Membership rules regulation , , public goods : goods avaliable to all (nonexclusive) + whose use by 1 Person doesn't reduce avaliability to others (nonrival - owned by no one , managed by communion ex. National Park open-access resource : a resource that offers unrestricted access is a common property resource that lacks any system of rules governing its use ex. air , open seas - most vunreable to tragedy of the commons · public resources include police , radio signal , etc. example : small lake What is marginal · willingness to pay ur to reduce contaminant · shows individual demand curve (downwards & · as willingness d , cost to Pay ↑ ~ We don't · want to take on the costfor public properties bloc concern for free-riders > - need collective decision making example : economic Sector most efficient from market Perspective time scale 3 4 YrS - · = to < 80 % Yield not max capacity , Up to Yo boats · allocation/regulation of property benefits natural resources · tragedy of the commons game MON , SEP 16th Competition - , time constraints resources , , and division of property drive depletion of a common resource PUBLIC GOODS CONT ~ 3 diff btw cost + revenue = & profit (blue line > similar to product curve should stop boats here but will not Stop Until Company collapse · max profit = 3 million · if we try to extract more> collapse · profit max = 700 boats · but in absence of regulation , , what will happen ? > - on individual scale , everyone will try to maximize their own concerns (don't have big scale Picture (where probably will Stop substantial decrease in profit · boats continue to go into fishery as long as SOME Profit on short-term. individual sccale diminishing returns (where should have stopped) < defines licence fee open access equilibrium 3. · maximize own returns on individual scale · tragedy of the commons Lideally should start from boat 1) (reduces profit substantially) (penalizes ppl late to process) licence fee should be cheaper w/ less boats > - increase wit boats ↳ or set fee of $4 , 000 during Peak season What if the fishery was privatized ? social benefit (access to water in case of drought) 3 human + nonhuman - - ecological benefit (biodiversity water resource Stakeholders , FISHERY MANAGMENT MECHANISMS 1) licence fee to access fishing 2) quota system limit access to resource thru restriction on species , time , etc. 3) quotas (ITQs) on tradeable rights to harvest resource ex. Permit to harvest particular quantity - rights can be sold to market - opens sector to broader group while keeping resources in check quota vs. tradeable quota · tragedy of commons both an economic + ecological problem ~ investment down the drain BENEFIT-COST ANALYSIS WED , SEP 18th · weighing cost+ benefit of doing something - limited resources (time , money - how can we increase our benefit to max possible eX how can you use cost-benefit analysis to determine optimal study ? · compare to benefits of doing something else EFFICIENCY- OPTIMALITY golden rule of econ : every action should continue until the additional benefit of doing the action falls below additional cost 1) Pare to efficiency : if no additional change could make at least one of you better without making the other worse off ex. giving 1 student $10 = improvement of 1 situation who making everyone's situation worse-off ex · eating entire Pizza by yourself at sleepover = other ppI didn't get more hungry b/c I ate the whole Pizza Pareto · improvement : if I had 3 leftover slices and gave those out · decisions aimed at 1 group 2) Utilitarian efficiency : Maximize the Sum of everyone's utility · overall society benefit 3) egalitarian efficiency : divide benefits equally among all Members 4) Rawlsian efficiency : Maximize Utility of the least well-off Person environmental impact assesment : identification + study of all significant enviro. repercussions stemming from a course of action · NEPA (1970) - National Enviro. Policy Act - any development that disrupts enviro. has to fill this report · might not factor all disruptions like culture , human behavior , risk analysis increase cost if included 1) regulatory impact analysis : once regulations are implemented how effective (is it really working efficiently ?) ex continue to sample water after regulation implementation 2) cost-effectiveness analysis : estimates cost of diff alternatives to show how they compare in terms of cost + outcome · what is the most cost-effective way 3) damage assesment : value of damages + who's responsible + compensations for those hurt BENEFIT COST ANALYSIS · helps we making public decisions from Society's standpoint - societal level · usually for policies/programs that have unmarketed outputs ex improvements in enviro. quality is the best outcome for society highest production or zero pollution? Marginal analysis depends on group · international whaling comission... # of whales that b enefit : Science culture , meat be harvested , should cost : genetic variation , future generations , imbalance to ecosystem lost · What is a cost or benefit depends on who is making the decision and what the commodity is measurement of benefits : stems from reducing damage · measure current + future emissions · determine values of physical impacts ex. Estimation of Clean Air btw 1990-2020 Study (EPA) · cost = $65 billion · benefit = $2 trillion (avoidance of cost) COST BENEFIT ANALYSIS CONT. - Fri , Sep 20th cost of illness (CO) approach : increased medical + other costs associated w/ particular pollution-related illness · avoided costs = benefits of Pollution control EFFECTS OF POLLUTION ON PRODUCTION COST & supply curve for degraded enviro. · more pollution increases production costs · fixed price given by market supplycove a producers do not influence for price of strawberries profit from Scenario #1 men & profit from Scenario 2 - cost from Scenario #1 a revenue from Scenario #1 problems with direct damage approach ? What's not included ? · ecosystem health + long-term implications not included · direct cost of headache = $20 for Tyleno but actually a lot more pain and suffering than that · incomplete · nonmarket contributions not included · medical cost# Paint suffering of illness · PPI + Markets normally change + adjust to enviro. Pollution = cost of changing behavior ex. loss from not having strawberries MEASURING OUTCOMES · depending on where a country is in its economic journey development will effect growth rate cost + benefit · cost of benefitting enviro. diff for diff countries Social cost : all the costs stemming from an action , and are equal to private costs + external costs produces electricity > reducing air ex Power Plant air pollution pollution -. + reduces social costs + increases production cost · agricultural subsidies incentivise chemical production methods that increase agricultural output + water air Pollution c reducing subsidies would increase national income+ reduce enviro. impacts BUT some farmers will be less off 1) opportunity cost : forgone values of alternative uses of resources eX. if you buy the jacket , you can't buy the shoes 2) transfer payments : Monetary amount that flow from 1 person to the other wo affecting resource commitments or true opportunity cost ex · taxes - just $ transfered to do other things 3) enforcement costs : resources used to monitor the behavior of firms , agencies , individuals subject to regulations + sanctioning violators 4) environmental costs : When emissions in 1 medium may cause increase into another example : wind energy power Plant * missed lecture on 9/23 - iPad died Loops horizontal equitym Vertical equity : Policy affects PPI in diff circumstances (diff income levels & ~ each group has similar/proportional benefits > - highest income benefits most - lowest income benefit most 7 MIDTERM Wed , Sep 25th 3 · MC + True/False · short answer questions from lectures · 1 or 2 application · extbook : supplement for complicated topics · lecture holes class activities , , supplementals to lecture Final * Lecture on MIDTERM VALUING THE ENVIRONMENT · still cost-benefit analysis · Value (broader) vs. Price (monetary value on certain component > cannot be marketed + diff. btw people , cultures , values , etc. · how to compare market benefits of goods/service to nonmarket benefits of ecological service + enviro. amenities ? · economics doesn't believe everyone has right to clean air - instead compares cost of degraded air and how it reduces our outcomes < benefit of clean air vs. Value of Market goods produced along w/ Pollution anthropocentric + biocentric · · econ. tries to find a way to convert nonmarket value into $ price in order to make econ. decisions total = sum of diff use + nonuse economic value values use value honuse value direct indirect option bequest existence use value use value Value value Valve · timber soil erosion control · · Welfare from · hiking/ hunting flood protection - - · polential keeping for just knowing · nontimber (fruit Carbon storage forest exists , · future future gens. mushrooms etc. ) resource openguins forest for , · future recreation - · future gens.

Price of home as function of # of rooms ex. close to landfill + how full it is defensive expenditure approach : Pollution valuation based on expenditures households take to avoid mitigate exposure to a Pollutant ex. Pay $20/mo for bottled water then their wip for improvement in drinking water quality is at least $20/mo Stated Preference : elicit respondents willingness to pay when Valve is not directly observable contingent Valuation (CV) : uses surveys to question PPI regarding their willingness to pay for a good endowment effect : concept that ppl lend to place higher loss on things they already have + value gain less WTP < WTA contingent ranking (CR) : survey method where respondents rank a list of alternatives Protest bids : responses to contingent valuation questions based respondents opposition to question on payment vehicle , not valuation of resource strategic bias behavior : tendency for PPI to state preferences or values inaccurately to influence policy decision value of Statistical live (VSL) : willingness to pay society to avoid 1 death based on valuations of changes in risk of death $100 million· $10/yr = $1 billion (households (pay) ($ to save 50pp) $1 billion/50 = $20 million (total $/PPI save) = (value of 1 life) Wage risk analysis : estimates value of a statistical life based on required compensation needed to entice ↑ risk jobs ppI to value of human life · MIDTERM REVIEW Mon Sep , 30th · worksheets , lectures , activities · pen/pencil + calculator · something must have a dollar value to be included in cost - benefit analysis
