In this context, the use of evaluation methods based on hypothetical markets, most widely used in the field of the evaluation of environmental goods or cultural heritage, could solve that problem.

It has been found Mattia et al. According to these general assumptions, the paper suggests the use of stated preference methods with the aim of replace in the appraisal models the market prices historical data of a sample of properties with the willing to pay for the same goods.

More in deep, of the various valuation stated preference SP techniques available, Contingent Valuation Method Dichotomous Choice Model has been used in order to estimate the market value of a sample of residential properties in the city of Milano. Even if the two main features of this method — the hypothetical character of the questions and the fact that actual behaviour is not observed but only predicted — has been broadly criticized Adamowicz et al.

Strategic bias has been reduced by pre-testing the valuation questionnaire and using different bidding mechanism according to two different groups of buyers selected, the one who answer that the property meets its needs and the second who is not really interested in it.

Starting from the critical analysis of the outcomes of this first case study, the paper suggests an evaluation procedure for the systematic production of economics data — median WTP — to use in statistical pluriparametric appraisal models in order to build up a databank of normal willing to pay for properties according to the principle of transparency.

Introduction In the field of real estate appraisal, the goal of the valuation process is to forecast the most probable value for specified properties. There are three commonly used approaches for determining value: the sales comparison approach, the cost approach and the income capitalization approach1. Generally the appraiser decides to apply one or more of these methodologies according to the scope of the appraisal2.

One of the most criticism in Real Estate appraisal processes based on sales comparison approach is the reliability of data about market prices of comparable properties. Furthermore, markets solve only a tiny corner of the overall problem of valuation, even for goods that are regularly and efficiently brought and sold Epstein The price is the result of actions by different market participants who may be affected significantly by a wide range of intrinsic and external factors3, that have become so difficult to predict that they cannot be considered reliable over time De Lisle As Random variable, the price explains the heterogeneity, uncertainty and limited information of buyers and sellers Kummerow Ratcliff called for valuers to reduce the uncertainty around the most probable price4, pointing out that valuation lies on the prediction of human behaviour5.

It is used to estimate buildings in their current use, when are not available meaningful market data. Cost does not equal market price very often. Sales transactions are necessary to reveal the current relationship of costs to prices.

The tendency will be for markets to adjust towards equilibrium, but because adjustments are slow, at any given time, the market is likely to be out of equilibrium. The sales comparison approach estimates value by comparing the subject property to similar ones being sold recently. Given the heterogeneity of properties, adjustments concerning physical characters, location, lease contracts, quality of tenants and market conditions are introduced in order to consider the differences between the subject property and the comparables.

More adequate are prices of comparable properties, more reliable can be considered the outcome of the valuation process. Sales comparison approach can lead to mis-pricing as price of a specific property at a point in time is a random variable reflecting the heterogeneity, uncertainty and limited information of buyers and sellers.

The income approach is used to value properties on the basis of the stream of income that is expected from them. Despite the approach requires to estimate the cash flows for the economic life a property and an appropriate rate to discount them, simplified methods, based on net operating income NOI of the first year and capitalization rate, are generally used.

The appraiser has the task of reconciling the values according to his experience, to the accuracy of data and procedures and to the market conditions.

The reconciliation methods vary from country to country. In the United States all three methods are used in most cases. In France only the sales comparison and the income approach are used. In UK appraisers apply a hybrid method. For a deeper treatment of these issues see Hoesli See also the concept of utility given by Lancaster: the price people pay for complex goods is a sum of the utility of various characteristics Lancaster, , Rosen, Some behavioral inputs are essentials: 1.

The paper is structured into seven sections. The introduction points out the key concepts about real estate appraisal. Follows a literature review on the use of Stated Preference valuation methods Contingent Valuation Method for the appraisal of real estate market value section 2.

Section 3 focuses on the theoretical assumptions. Section four describes the use of contingent valuation method CVM for estimating the market value of a sample of residential properties in the city of Milano section 4.

Section five concludes the paper and puts forward further research issues. Apart from the different fields of application, all SP techniques create a hypothetical market for the good being valued by a survey that describes the good, the reasons of payment and the payment vehicle7. Contingent valuation method CVM ask respondents the amount they are willing to pay for the good being valued. The most important difference between CVM and Choice Modelling approach is that the former is more suitable to evaluate a good as whole, while the latter is more likely to be required when the interest is on preferences for the individual characters of good being valued8.

CVM is based on the direct elicitation of individuals preferences about hypothetical choices through the use of carefully designed and administered sample surveys Arrow et al. After its theoretical settlement by Ciriacy-Wantrup in , CVM has obtained several attentions because of the increasing importance of non-use values estimate.

Thus, it has been applied to a wide range of problems including water quality, wilderness and wildlife protection, air quality, health care, food safety, cultural heritage preservation by federal and state agencies, governments and international organizations like the World Bank.

The goals of the first stage are: defining the initial items of the research as what is the object being valued; settling the hypothetical market10; the market; 4. In order to understand the determinants of WTP bids, in stage 4 a bid curve can be estimated. For a continuous question format linear least squares estimation techniques are typically used.

With a dichotomous payment format a logit or a probit18 approach is required, which relates the probability of a yes answer to each suggested sum to the explanatory variables.

In stage 5 the total value is obtained from mean WTP according to the targeted population. CVM is the subject of great controversy from both economic and psychological point of view, causing users of this technique to pay great attention to preference elicitation and to reliability of the method.

The choice of sample size concern cost and precision of estimate. It depends on: the variance in the underlying population; the precision required in the estimates; the likely response rate; the need for any disaggregated information, i.

The Iterative bidding game submit to respondents different rounds of discrete choice questions or bids, with a final open-ended WTP question. Thus, the result is a continuous bid variable that may therefore be analyzed using ordinary least squares approaches OLS. The result is a discrete bid variable, that requires logit-type analysis. Face to face interviews are highly flexible, allow the greatest control on answers and clarification if complex questions are included, but they are very expensive.

See Pearce et al. They are used to model a relationship between a dependent variable Y and one or more independent variables X. Nevertheless these criticisms are widely acknowledged also by the proponents of CVM, they believe that future CV studies will solve all the objections.

At this purpose, each of them has been widely discussed by the Contingent Valuation Panel, suggesting recommendations for CV studies in order to minimize the controversies emerged ibidem. Applying Stated preference methods in Real Estate Appraisal: a targeted literature review Despite CVM is a method traditionally applied in order to estimate the value of non-market goods in several planning and policy contexts20, in the late s its use in the valuation of real estate has been suggested.

Thus, the disparity between stated and actual WTP remains a problem still open. Cummings et al. Unlike the past experiments in this field, the results of the experiments carried out by Loomis and other researchers of the USDA Forest Service show a reduction of this divergence of WTP23, due to some important reminders to respondents: not to state what they thought to be the fair price; to act as they were in a real market and to consider their household budget.

In more recent years few published studies concern the use of CVM for predicting specific real estate impacts in the context of litigation to determine the impact of contamination on property values Despite the effort expended to make the hypothetical choice as real as possible in order to get the maximum reliability of responses25, relevant researches have been carried out concerning that criticism.

Starting from this research experience, Ridker used the CVM many times in order to estimate air pollution effects. In the next years other economists used the CVM to value several recreational amenities Randall et al.

Most of the latter concern common market goods, such as a chocolate bar Kealy et al. It is also a good simply observable and not too expensive.

The WTP has been estimated by an Open ended format. Besides the previous flaws, he shows that applying CVM to real estate market means so many violations of the NOAA guidelines as to make it unreliable Mathews , on the basis of a close inspection of specific CV questions and analysis techniques for better understanding why CVM fail to generate reliable estimates of property value losses associated with environmental disamenities, recognizes the practical impossibility for a property value CV survey to involve dynamic market conditions and all the information that real buyers and sellers generally consider.

The following paragraph suggests the use of CVM in order to estimate the willingness to pay for a sample of residential properties in the city of Milano, then compared to market prices27, answering to the call of Contingent Valuation Panel for external validation of CVM — that is still considered the most important weakness of CVM — in context where values estimated by this technique can be compared with real values of goods that can actually be bought and sold Arrow et al.

Case study28 As afterwards described Contingent Valuation Method has been used in order to estimate the market value of a sample of residential properties in the city of Milano.

More in depth has been considered four apartments, whose size is 55 sqm Maroncelli , 67 sqm Gobetti , 65 sqm Bassi , 35 sqm Cambiasi. As the first two has been sold, their market price is well known.

Each individual of the sample knows the apartments by a direct visit or by a card including both a detailed description of the dwellings, of the building and of the urban context and pictures of outside and inside of the apartments.

The questionnaire As a careful questionnaire design is essential for the validity of the outcomes, its comprehensibility has been tested before administration. The questionnaire used in this case study involves four questions. The first ask respondents if the apartment meet their needs. According to these answers, the sample has been divided in two sub-samples: the sub-sample A, including those are really interested in the apartment; the sub-sample B, including instead those not considering the good suitable to their needs see table 1.

This division of the sample in two sub-sample is required by the different meaning of WTP information in each of them. Furthermore, it makes possible to verify potential strategic behaviors in WTP eliciting by those are going to start a real transaction aimed to the purchase.

Size of two sub-sample 26 Wilson also stresses that the valuation community widely recognizes that there is no substitute for an in-depth analysis of real sales information, since there is a big difference between an opinion expressed under hypothetical conditions and real transactions ibidem.

For the sub-sample A the elicitation question has been formulated according to the Close Ended- Dichotomous Choice approach, because it avoids bias more than the other formats.

A slim majority of the participants would accept paying more in taxes for CERN. The estimated willingness to pay is higher than the current implicit per capita tax burden of French citizens. The experimental setting is novel and replicable for empirically assessing social attitudes towards science for other research infrastructures and countries.

Review of valuation from a non‐market perspective: travel cost method for rural tourism

The growing deterioration of natural resources creates the need to value ecosystem services, including biodiversity. The economic value has focused on non-market goods and services, which is complicated. Techniques have been developed to measure these values whose acceptance has increased lately. A search of economic valuation made in Mexico was conducted. Almost all valuation studies undertaken in the country are restricted to travel cost TCM and contingent valuation CVM methods.

Banzhaf, H. Spencer : Constructing markets: environmental economics and the contingent valuation controversy. Forthcoming in: History of Political Economy. As economists took up the task of measuring the "demand" for environmental services not traded in markets, some chose to substituted survey-based methods known as contingent valuation CV. Doing so, they could not help but find themselves in the uncomfortable position of self-evidently constructing their observations rather than merely observing them.

Economic valuation methods for non-market goods and services comprise a range of empirical approaches to estimate a monetary value for the trade-off a person would be willing to make to increase the amount or the quality of a good or service for which there exists no market. After a period of more than fifty years of improvement, the approaches have reached a certain degree of maturity and professional acceptance; for example, they are routinely used in US court cases as a starting point for oil-spill damage assessments which can run into several billions of US dollars. There are probably more than 10, papers published, covering a range of issues about economic valuation methods. While environmental and health studies dominate, an increasing number of applications appear in, inter alia, cultural economics. Since the number of things people care about is virtually without limits, the set of applications for measuring these types of trade-offs is very large; e.

The paper reviews existing valuation methods to better understand how estimates of rural tourism products and services are conducted. The paper also critically evaluates the applicability of these methods. The study concludes that the selection of a method is mainly based on applicability of the approach. A review of previous studies suggests the evaluation of the practicality of each method according to the topic studied. Herman bin Mohammad Afandi, S. Emerald Group Publishing Limited.

Real estate and trails professionals take a different view than economists, who see increases in property values as a redistribution of wealth offset by decreases elsewhere. There is also a subjective component to consider, as not all homeowners consider a trail to be an asset. Willingness-to-pay refers to the amount that an individual is willing to pay to use a non-market good such as a trail or greenway.
