Abstract: Harberger taxes have been a hot topic since E. Glen Weyl's new book Radical Markets and his paper published with Vitalik Buterin and Zoë Hitzig. It's been described by Simon de la Rouvier as "an economic policy that aims to strike a balance between pure private ownership & total commons ownership in order to increase general welfare of society." Blockchains provide great testing grounds for economic experiments like Harberger Taxes, so we've done just that using online advertisements to apply the concept.
Harberger Ads is an ad serving utility that prices ad space using Harberger Taxes. Ad space can be purchased and tax is paid at a self assigned "property value". Reasonable pricing is encouraged as each property is for sale at the set value. If priced too low (with the goal of avoiding taxes), the property could be bought unexpectedly. If priced too high, respectively high tax payments will follow.
The model also allows a property lister to easily monetize a space without the complications of preset complex advertising pricing models and contracts, and without the need to work with a centralized high-commission marketing platform.
