This paper introduces information aggregation into the standard spatial committee game. We assume that committee members must agree on a decision rule to aggregate their private information on a policy-relevant state of the world. We derive sucient conditions for the ex ante incentive compatible...

We analyse committees of voters who take a decision between two options as a two- stage process. In a discussion stage, voters share non-verifiable information about a private signal concerning what is the best option. In a voting stage, votes are cast and one of the options is implemented. We...

What is the optimal size of expert committees? To address this question, I present a model of a committee of experts with career concerns. Each expert may observe an argument about the state of the world but be unsure about the argument's soundness. Experts may remain silent or compete for the...

We introduce the notion of verifiable information into a model of sequential debate among experts who are motivated by career concerns. We show that self-censorship may hamper the efficiency of information aggregation, as experts withhold evidence contradicting the conventional wisdom. In this...

We consider a general economy, where agents have private information about their types. Types can be multi-dimensional and potentially interdependent. We show that, if the interim distribution of types is common knowledge (the exact number of agents for each type is known), then a mechanism...

Specialized theoretical and empirical research should in principle be embedded in a unified framework that identifies the relevant interactions among different phenomena, enables an appropriate matching of policy instruments to objectives, and grounds normative analysis in individuals' utilities...

This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation—notably, raising revenue, redistributing income, and correcting externalities—and the mapping between these functions and various...

This work intends to specify a formula for the optimal taxation in Probabilistic Voting Models with Single Mindedness Theory. The goal is to find an equivalent expression to the Ramsey’s rule for a political economy environment where Governments are assumed to be Leviathans rather than...

This paper is motivated by a practical income (or wealth) taxation problem: For a public good economy where the provision of public goods is to be financed by income taxes collected from individuals, what is the optimal feasible tax mechanism when a social planner is relatively uninformed of the...
