I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements...

We propose a flexible majority rule for central bank councils where the size of the majority depends monotonically on the change in interest rate within a particular time frame. Small changes in interest rate require a small share of supporting votes, even less than 50%. We show that flexible...

Majority rules are frequently used to decide whether or not a public good should be provided, but will typically fail to achieve an efficient provision. We provide a worst-case analysis of the majority rule with an optimally chosen majority threshold, assuming that voters have independent...

We examine optimal procedures for public project provision, financing, and redistribution in democracy. We consider a large and heterogeneous decision body and show that first-best outcomes are obtained by a procedure that involves two proposal-making rounds, the right of the minority to move...

I develop a model of ideologies as collectively sustained (yet individually rational) distortions in beliefs concerning the proper scope of governments versus markets. In processing and interpreting signals of the efficacy of public and market provision of education, health insurance, pensions,...

The determinants of government responsiveness to its citizens is a key issue in political economy. Here we develop a model based on the solution of political agency problems. Having a more informed and politically active electorate strengthens incentives for governments to be responsive. This...

Do foreign educated individuals play a role in promoting democracy in their home country? Despite the large amount of private and public resources spent on foreign education, there is no systematic evidence that foreign educated individuals foster democracy in their home countries. Using a...

One of the most cherished propositions in economics is that market competition by and large raises consumer welfare. But whether political competition has similarly virtuous consequences is far less discussed. This paper formulates a model to explain why political competition may enhance...

We study the dynamic support for fiscal decentralization in a political agency model from the perspective of a region. We show that corruption opportunities are lower under centralization at each period of time. However, centralization makes more difficult for citizens to detect corrupt...

A political constitution is like an incomplete contract: it spells out a procedure for making decisions and for delegating power, without specifying the contents of those decisions. This creates a problem: the appointed policymaker could use this power for his own benefit against the interests...
