The travel-cost method is of limited value if congestion is a problem. Small changes affecting recreational quality may be difficult to evaluate using this method. The basic assumption of travel-cost method is that consumers treat increase in admission fees as equivalent to increase in travel cost. This is subject to question. Another problem associated with this method is that it assumes recreational quality remains constant over the range from zero use to full present use at the going admission fee.
This is highly hypothetical. Bateman is of the view that the travel-cost method measures only the use value of recreation sites. Underestimation of site value due to the truncation of non-visitors would be made worse if the non-use value of both visitors and non-visitors were relevant. This method is not capable of producing any total economic value estimate in that it cannot estimate non-use items such as existence value.
The underlying assumption of the hedonic price method is that the price of a property is related to the stream of benefits to be derived from it. The method relies on the hypothesis that the prices which individuals pay for commodities reflect both environmental and non-environmental characteristics.
The implicit prices are sometimes referred to as hedonic prices, which relate the environmental attributes of the property. Therefore, the hedonic price approach attempts to identify how much of a property differential is due to a particular environmental difference between properties, and how much people are willing to pay for an improvement in the environmental quality that they face and what the social value of improvement is.
The hedonic price method is based on consumers which postulates that every good provides a bundle of characteristics or attributes. Again, market goods can be regarded as intermediate inputs into the production of the more basic attributes that individuals really demand. The demand for goods, say housing can, therefore, be considered as a derived demand. For example, a house yields shelter, but through its location it also yields access to different quantities and qualities of public services, such as schools, centres of employment and cultural activities etc.
Further it accesses different quantities and qualities of environmental goods, such as open space parks, lakes etc. The price of a house is determined by a number of factors like structural characteristics, e. Controlling the non-governmental characteristics which affect the demand for housing, permits the implicit price that individuals are willing to pay to consume the environmental characteristics associated with the house to be estimated.
The hedonic price function describing the house price Pi of any housing unit is given below:. Where, S represents structural characteristics of the house i i. It is assumed that only one environment variable affects the property value i. There is a positive relation between air quality and property price as shown in Figure The figure indicates that house price increases with air quality improvement. Figure The hedonic price method has become a well-established technique for estimating the disaggregated benefits of various goods attributes.
In the case of housing, these attributes include not only basic structural and amenity characteristics but also environmental characteristics such as clean air, landscape and local ecological diversity. Thus, when a particular policy is implemented which will have a very great effect on the local environment, the hedonic method offers a useful way of estimating the change in amenity benefits.
This method is of no relevance when dealing with many types of public goods i. The hedonic price method may be used to estimate the environmental benefits provided to local residents by an area as it exists today. But in fact, it cannot reliably predict the benefits which will be generated by future improvements because those improvements will have the effect of shifting the existing function.
If expectations are not the same as measured by present pollution estimate, then there are clearly problems relating to values derived from purchases. Moreover, expectations regarding future environmental quality may bias present purchases away from that level dictated by present characteristic levels.
This method has been criticised for making the implicit assumption that households continually re-evaluate their choice of location. Further, there is considerable doubt that such an assumption can hold in the context of spatially large study areas. If people cluster for social or transportation reasons, the results of this method will be biased.
The preventive expenditure method is a cost based valuation method that uses data on actual expenditures made to alleviate all environmental problems. Often, costs may be incurred to mitigate the damage caused by an adverse environmental impact. For example, if drinking water is polluted, extra purification may be needed.
Then, such additional defensive or preventive expenditure could be taken as a minimum estimate of the mitigation of benefits beforehand. In the preventive expenditure method, the value of the environment is inferred from what people are prepared to spend to prevent its degradation. The averting or mitigating behaviour method infers a monetary value for an environmental externality by observing the costs people are prepared to incur in order to avoid any negative effects.
For example, by moving to an area with less air pollution at a greater distance from their place of work thus incurring additional transportation costs in terms of time and money. Both of these methods are again, conceptually closely linked. These methods assess the value of non-marketed commodities such as cleaner air and water, through the amount individuals are willing to pay for market goods and services to mitigate an environmental externality, or to prevent a utility loss from environmental degradation, or to change their behaviour to acquire greater environmental quality.
When no market exists for a good or service and therefore, no market price is observed, then surrogate or substitute markets can be used to derive information on values. For example, travel-cost information can be used to estimate value for visits to a recreational area; property value data are used to estimate values for non-marketed environmental attributes such as view, location or noise levels.
The effects of environmental damages on other markets like property values and wages of workers are also evaluated. Valuation in the case of property is based on risks involved in evaluating the value of property due to environmental damage. Similarly, jobs with high environmental risks will have high wages which will include large risk premiums.
In the property-value method, a surrogate market approach is used to place monetary values on different levels of environmental quality. In areas where relatively competitive markets exist for land, it is possible to decompose real estate prices into components attributable to different characteristics like house, lot size and water quality.
The marginal willingness to pay for improved local environmental quality is reflected in the increased price of housing in cleaner neighborhoods. The wage-differential approach is a surrogate market approach that uses information on differences in wage rate for similar jobs in different areas to estimate monetary values for different levels of environmental quality.
This approach has been used to estimate values for such environmental variables as different levels of congestion, air pollution and aesthetics. Wages also vary in response to various factors such as education and training, natural dexterity, experience, demand and supply in each labour market area, occupational risks to health, probability of death, and associated living conditions including environmental ambience etc.
The hedonic wage approach has also been used in the wage-risk analysis to determine the value of life and limb in relation to the hazards faced at work. The general hedonic wage equation can be expressed as. The hedonic wage approach has traditionally been used to measure employment attributes, principally risk of death or injury in particular labour markets. However, by observing variations in wage levels over space, and netting out the influence of other attributes, they have also been used to value the quality of life over large areas such as countries or continents.
This method values the benefits of environmental protection in terms of what is being foregone to achieve it. This forms the basis of compensation payments for the compulsory purchase by the government of land and property under eminent domain laws. Further, it assumes that the land owner or user has property rights over the use of the land or the natural resource, and that to restrict these rights the government, on behalf of the society, must compensate the owner.
The opportunity cost method is useful in cases where it is difficult to enumerate the benefits of an environmental change. For example, rather than comparing the benefits of various alternative conservation schemes in order to choose between them, the method can be used to enumerate the opportunity costs of foregone development associated with each scheme with the preferred option, being the one with the lowest opportunity cost.
The opportunity cost method does not include non-marketed public good values of land. The fact that land and its attributes produce externalities is explicitly recognised in regulatory land-use planning controls, which seek to minimize external bads through development control and land-use class orders, by separating externality producing land uses spatially. Thus planning controls seek to preserve amenity benefits by restricting the development of land.
However, by imposing such restrictions, the price of land, such as green belt land, has a lower financial value than its opportunity cost value. This is a cost-based technique used to estimate the monetary value of environmental damages based on the potential costs of relocating a physical facility that would be damaged by a change in environmental quality. This method relies on data on potential expenditures. This is a Cost-based technique that measures the potential expenditures that would be required to replace or restore a productive asset that would be damaged by some project or development.
These costs are then compared to the costs of preventing the damage from occurring to determine which is more efficient. Despite the rhetoric, economists have not found clear evidence of the net effect of environmental regulations on employment. The impact often depends on the type of industry and the health of the economy. But there is little indication that environmental regulations substantially impact overall employment figures.
The trouble is, these jobs may be in a different location — at a solar-powered plant in another state, perhaps — requiring a costly move. Costs: A paper in the Journal of Environmental Economics and Management describes how pollution-abatement regulations appear to affect larger businesses more than smaller ones. That efficiency can help competitiveness or even offer a firm a first-mover advantage, both of which would lead the firm to hire more workers.
Taxes vs. The tax would substantially reduce employment in the polluting sector, the paper argues, while employment would increase in sectors not impacted by the tax. The net job impact is small, even in the short-term. Health benefits and the greater good: An award-winning paper by Berkeley economist W.
Wage disparities: European Union-funded research observes that in the U. These jobs are driven less by regulation and more by local green activism and federally funded research labs — in short, these often are in highly educated areas with universities.
Designing compassionate policy: New environmental policies can be designed to minimize harm. Though most policies will result in no net change to employment, policies that could result in large job losses in regions with high unemployment especially at times of high nationwide unemployment could be offset by targeted assistance and job-creation programs such as targeted tax credits, argues a paper in the Review of Environmental Economics and Policy.
The paper holds that the social costs like unemployment are still outweighed by the net benefits like healthier children of scrapping dirty energy in favor of green alternatives. Different unions, though, have often come out on different sides of arguments about regulatory change, such as the Kyoto Protocol on global warming.
