We find that a player who is a member of multiple groups aggregates information and serves as a conduit through which information from one group spills over to another. We also find that such players are more influential than similarly situated players who are members of only a single group. We introduce a novel measure of the magnitude of information spillovers, and we identify the behavioral characteristics of the players that determine these magnitudes. While between-group spillovers occur, we find that their magnitudes are smaller than social learning theory predicts.</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"28 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The government announces a per unit (or excise) tax rate and auctions-off a number of tax exemptions. Namely, it invites the firms in the market to acquire the right to be exempted from the per unit tax. The highest bidders are exempted by paying their bids; and all other firms remain subject to it. The mechanism has a number of desirable features. First, it allows the government to collect more revenues than the standard tax policies. Further it reduces distortions as fewer firms pay the per unit tax. The mechanism reduces also the excess entry of firms that often occurs in oligopolistic markets. It creates no discrimination as <i>all</i> firms end up having the same net payoff, and it is voluntary as the firms choose whether to participate in the auction or not (and hence choose how to be taxed). Our mechanism can be seen as the product-market analog of the income tax buyout fiscal mechanism (Del Negro et al. 2010).</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"28 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the standard formulation of competitive equilibrium neglects the mechanism of price formation, treating prices as exogenous. Here, we study explicit price formation mechanisms: trade intermediated by market-makers and trade via search and bargaining. We find that as the number of types in the economy grows, the informational complexity of random search diverges to infinity relative to the competitive market. This divergence can be avoided if market makers intermediate trade. Thus, this analysis provides a novel rationale for organized markets if agents' capacity to manage informational complexity is bounded.</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"28 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148068166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We characterize how the interaction between asset characteristics and ownership structure determines the possibility of efficiency. Our main finding reveals a fundamental misalignment principle when goods are heterogeneous: efficiency is possible precisely when complementarity and ownership structure are <i>misaligned</i>. Under concentrated ownership (one agent owns both assets), efficiency is possible when assets are substitutes but impossible when they are complements. Under dispersed ownership (each agent owns one asset), the opposite holds: efficiency is possible when assets are complements but impossible when they are substitutes. This misalignment creates asymmetric valuations that overcome the participation constraints binding efficiency. Our results shed new light on the classic Myerson-Satterthwaite impossibility and Cramton–Gibbons–Klemperer possibility theorems to multi-asset environments, showing that the structure of asset bundles fundamentally alters the rents that we need to provide to ensure truthfulness and voluntary participation.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"28 2","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpet.70109","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utility of the bureaucracy depends on habit formation. The bureaucrat derives utility from consumption of current and past regional public good levels. The central government's objective function is the sum of regional utilities. Regional and central governments play an infinite-horizon sequential game in which regional governments are policy leaders with respect to their choices of public-good levels. These choices produce regional deficits. The central government observes regional deficits and then choose deficit-relief federal transfers to reduce regional costs of fiscal insecurity faced by regional residents. There is a common-pool property associated with federal funds. The federal transfers do not eliminate regional deficits. Observing this, regional governments raise additional funds to eliminate deficits. We derive the steady-state equilibrium, examine its properties and compare it with alternative equilibria, which provide useful benchmarks.

Alliances enhance the probability of winning at the cost of sharing the prize if won, while technological partnerships reduce the marginal cost of the effort invested in the contest by the members. When agents exhibit extreme free-riding behaviors at equilibrium, the stabilization of the grand alliance by technological cooperation requires players to be able to block any deviation in the alliance structure involving their technological partners. Nevertheless, when the agents manifest fewer free-riding intentions, the threat of being excluded from a global technological partnership is sufficient to ensure the stability of the grand alliance in the long run. When exclusions are possible, global cooperation in technology between agents in a situation with limited free-riding behaviors between partners can completely annihilate competition in the contest. This indicates that free-riding behaviors hinder the stabilization of the grand alliances in contests. As no alliance structure is stable when the agents cannot form any technological partnership, these findings highlight that the existence of technological coalitions is a facilitating factor for the formation of alliances in contests.</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"28 2","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147614919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the stochastic two-type setting with exogenously-given factor input prices, our calibrated numerical experiments find that the marginal capital wedges for both types on their period-1 savings are positive, indicating the government's motive to relax individuals' incentive-compatibility constraints.
