This paper aims at providing a concise description of the current state of the discussion around the mechanism of Harberger taxation, and Posner & Weyl’s proposal to universally implement it. In a second part, some thoughts on the consequences of a particularly relevant concern are explored: the failure of agents to assess the value of their property. This might lead to the Harberger tax placing potentially rather different effective tax rates on asset owners, depending on their personal characteristics.
In their book "Radical markets: Uprooting capitalism and democracy for a just society", based on a series of papers by the authors and affiliates, Eric Posner and Glen Weyl introduce the idea of partial common ownership: every asset in the economy is constantly auctioned through a mechanism that has been existent in a small strand of literature for quite some time—Harberger taxation. The mechanism has been endorsed by some scholars for its combination of simplicity and incentive compatibility (regarding truthful revelation of valuations), enabling the economy to move to a state of higher allocative efficiency. Other scholars have pointed to some practical, but fundamental issues that might cripple a system of universal Harberger taxation (such as failure to assess value).

Objectives and Themes
This paper examines the mechanisms and economic implications of the Common-Ownership Self-Assessed Tax (COST) as proposed by Posner and Weyl. It specifically investigates whether the introduction of a universal Harberger tax could lead to unintended, attribute-dependent distortions for agents with uncertain property valuations.
- The theoretical foundations and mechanics of Harberger taxation.
- The academic discourse regarding allocative efficiency and market incentives.
- The impact of heterogeneous evaluation costs on asset owners.
- The role of loss aversion in property valuation and tax burden distribution.
- Normative implications of universal Harberger tax implementation.
Excerpt from the Book
IV ATTRIBUTE-DEPENDENT TAXATION
In this section, we want to consider an issue that might arise from the fact that agents typically are uncertain about their own valuations: attribute-dependent taxation. The essence here is that through heterogeneities across owners of similar assets (different cost of finding out a valuation in one instance, different degree of loss aversion in the other), owners will be taxed based on their personal attributes, in addition to the value of their asset.
This (unintended) differentiation in effective tax rates, which we will call “attribute-dependent taxation”, is of course also prevalent under a full-private-property scheme—however in the instances considered below, a Harberger tax arguably makes things worse. Since one can think of many other ways in which different agents might influence their effective tax rates (e.g. by trying to depress the sale probability through making the asset look bad), it is important to be aware of the different possibilites for differing effective tax burdens when doing normative analysis on the Harberger and conventional taxation.
Summary of Chapters
I Introduction: This chapter contextualizes the COST within the history of self-assessment-based property taxation and outlines the paper's focus on attribute-dependent taxation.
II Basic notions of Harberger taxation: This section formally models the Harberger tax mechanism and demonstrates how owners determine their optimal announced reservation price.
III The academic discussion around Harberger taxation and the COST: This chapter reviews the literature on mechanism design, emphasizing the trade-offs between universality, self-enforcement, and potential inefficiencies in real-world applications.
IV Attribute-dependent taxation: This chapter analyzes how individual uncertainties and personal attributes, such as evaluation costs and loss aversion, can lead to disproportionate tax burdens under a Harberger system.
V Conclusion: This chapter synthesizes the findings, suggesting that while the Harberger tax offers significant benefits, its impact on poorly informed agents warrants further investigation.
A Appendix: This section provides the formal mathematical proofs for the propositions and second-order conditions discussed in the main text.

Frequently Asked Questions
What is the primary subject of this academic paper?
The paper evaluates the Common-Ownership Self-Assessed Tax (COST) system, focusing on its theoretical functioning and potential societal impacts.
What are the core thematic areas discussed?
The core themes include mechanism design, property rights theory, the impacts of valuation uncertainty, and the normative implications of tax reform on different types of asset owners.
What is the central research question?
The research explores whether the implementation of a universal Harberger tax creates unintended, attribute-dependent effective tax rates that vary based on idiosyncratic personal traits.
Which scientific methodology is employed?
The author uses mathematical modeling, comparative statics, and literature synthesis to analyze the behavior of agents under a Harberger tax system.
What does the main body of the work cover?
It covers the formal modeling of the tax mechanism, a survey of existing academic debates, and an original analysis of how evaluation costs and loss aversion affect tax outcomes.
Which keywords best characterize this work?
Key terms include Harberger taxation, COST, allocative efficiency, property rights, loss aversion, and attribute-dependent taxation.
How do evaluation costs affect the viability of a Harberger tax?
The paper argues that individuals with higher costs to evaluate their assets face higher effective tax burdens, which may lead to welfare losses and disproportionate negative impacts on these owners.
What role does loss aversion play in the author's analysis?
The author demonstrates that loss-averse agents tend to announce higher reservation prices, effectively increasing their tax burden compared to less loss-averse counterparts in similar market positions.
Does the author suggest that the current property system is perfect?
No, the author acknowledges that current tax systems also contain distortions, but emphasizes that a Harberger tax might magnify certain issues related to personal attributes.
What is the final recommendation regarding the implementation of the COST?
The author concludes that while the system offers theoretical benefits, the unpredictable consequences for poorly informed owners require further research before implementation.
