 Virtual valuation

For an absolutely continuous valuation distribution with density $f(v)>0$, its virtual valuation is $v-(1-F(v))/f(v)$. The virtual-surplus revenue identity converts expected incentive-compatible payments into expected allocations weighted by virtual valuations. A regular prior makes this quantity nondecreasing.

Virtual valuation refers to the process of assessing the worth or value of an asset, property, company, or investment using digital tools and methodologies, often without the need for a physical inspection or in-person evaluation. This approach has gained popularity due to advancements in technology, including the use of algorithms, data analytics, and online platforms.
