SANDOVAL CHAVEZ, Diego Adiel et al. Economic valuation of the multifunctionality of urban parks: an explanatory análisis. Rev. econ. [online]. 2021, vol.38, n.96, pp.89-119.  Epub May 07, 2021. ISSN 2395-8715.  https://doi.org/10.33937/reveco.2021.176.

Urban parks provide a great variety of environmental, social and economic benefits. The value of these benefits is elusive and oftentimes studies overlook it. In a search for urban park economic valuation-related papers in databases and search engines, an explanatory analysis of the overall characteristics of the economic valuation models applicable to urban parks could not be found. The objective of this work is to perform such an endeavor. By conducting an explanatory-descriptive research, through a longitudinal study, 120 publications in the English and Spanish languages, corresponding to a period of 57 years (1963-2020) were analyzed. Publications were categorized in hedonic price model, travel cost model, and contingent value. For each of these three schemes the subcategories primary theory, secondary theory, opinion, review and case study were also considered. The aim was to analyze and understand the context and circumstances in which they were conducted, and to evaluate their relevance, strengths, and weaknesses. This approach led to realize what models are still in use and how they are adopted. The hedonic pricing model using the semi-logarithmic regression format is the most widely used for valuation, mainly in the United States and Europe. In can be concluded that the economic valuation of urban parks is a subject of global interest due to its contribution to attain sustainability in the urban realm.
