Podsumowanie	Benefit transfer is the practice of estimating the economic value of a nonmarket good — clean water, a recreation site, an endangered species, an avoided health risk — at a new 'policy site' by adapting value estimates from one or more existing 'study sites' where primary valuation research was already conducted. Because original contingent-valuation, choice-experiment, or hedonic studies are expensive and slow, analysts facing limited time and budgets transfer existing results, ranging from simply borrowing a single dollar value (unit value transfer) to transplanting an entire estimated valuation function (function transfer) or predicting from a meta-regression of many prior studies.	Ecosystem Services Valuation (ESV) is a framework pioneered by Costanza and colleagues (1997) that assigns economic value to the benefits nature provides to humanity—from pollination and water purification to climate regulation and cultural enjoyment. Formalized in the Millennium Ecosystem Assessment (2005) and The Economics of Ecosystems and Biodiversity (TEEB 2010), ESV bridges ecology and economics to make the invisible value of ecosystems visible to policymakers and markets.
