Any country in the aftermath of transition to democracy confronts the challenge of transitional justice, that is, the task of designing a system of procedures for holding perpetrators and collaborators of the ancien regime responsible for their past activity. Two important normative goals that transitional justice shares with any system of justice are avoiding false convictions (punishing the i…
This article presents a model of collective choice when group decisions must be justified by arguments from first principles. Individuals may have preferences over both the actions chosen and the arguments used to justify them. Defining a notion of stability in the arguments made and actions supported within a group, I characterize the set of actions that can be justified as well as the argumen…
Levine and Palfrey's QRE account of turnout in large elections raises the broader question of how much of a departure from standard rational choice theory is justified by the considerable repertoire of rational choice anomalies that has accumulated since Downs and Olson half a century ago. An alternative but more controversial unconventional view turns on what I call NSNX motivation to account …
This article compares convergence of political parties when voters are voting strategically and when they are voting sincerely under low-information conditions. In order to examine this problem, I create a computational model of a party system, where parties are uncertain about the distribution of the electorate. In one condition of the model, voters vote sincerely; in another, voters vote stra…
In collective decision making bilateral deals can increase or decrease the likelihood of finding compromises, depending on whether such deals have externalities. Positive externalities mean third actors profit from bilateral deals, whereas negative externalities mean bilateral deals hurt third actors. We develop the first model of collective decision making that takes externalities into account…
Had the destruction and suffering visited upon New Orleans by Hurricane Katrina been the result of a terrorist attack, it would have been very successful — not because of the number of innocent lives lost or amount of property destroyed, but rather because of the breakdown of the social order. What better possible outcome could a terrorist envision than planting seeds of doubt regarding the wil…
This article examines the effect of a strategic news media on legislators' interactions with their constituencies. Specifically, legislators can only be constrained by constituency preferences over policies when voters have the information to hold legislators accountable for their actions. A strategic news media can provide such information in a constant and continuous manner unlike, say, chall…
This essay constructs a theoretically rigorous explanation of the 1914 European war that involved Austria—Hungary, Germany, Russia, and France. It also serves to confirm Trachtenberg's contention that `one does not have to take a particularly dark view of German intentions' to explain the onset of war in 1914 and `question the ``inadvertent war'' theory'. A number of related questions about the…
This article pursues two line of inquiry in response to Bent Flyvbjerg's advocacy of a phronetic social science in Making Social Science Matter (2001). First, I explore how Flyvbjerg's manifesto relates to the approach employed in his earlier empirical work, Rationality & Power (1998). There are, I argue, notable disjunctions between the practice of Rationality & Power and the preaching of Maki…
Voters in democracies can learn from the experience of neighbouring states: about policy in a direct democracy (`policy experimentation'), about the quality of their politicians in a representative democracy (`yardstick competition'). Learning between states creates spillovers from policy choice, and also from constitutional choice. I model these spillovers in a simple principal-agent framework…
The article considers Approval Voting for a large population of voters. It is supposed that voters evaluate the relative likelihood of pairwise ties among candidates based on statistical information about candidate scores. This leads them to vote sincerely and according to a simple behavioral rule we call the `Leader Rule'. At equilibrium, if a Condorcet-winner exists, this candidate is elected.
Literature on international organizations points to several potential sources of bargaining power: voice, exit, and exclusion. In some circumstances, a member state may be able to effectively voice objections to a change to an organization's institutions. In others, it may threaten to leave the organization if its demands are not met. Finally, member states may be able to force a laggard member…
In 2005, the Democratic National Committee adopted the 50-state strategy in lieu of the strategy of focusing solely on battleground states. The rationale given for this move is that campaign expenditures are durable outlays that impact both current and future campaigns. This article investigates the optimality of the 50-state strategy in a simple dynamic game of campaign resource allocation in …
I examine a model in which multiple legislative principals monitor a bureaucratic agent's implementation of a project. The principals can each perform oversight of the implementation to limit information asymmetries exploited by the agent. Oversight is costly to perform and due to information leakages between principals, oversight by one principal reveals information to all principals. Thus for…
The amount of political information that voters decide to acquire during an electoral campaign depends, among other things, on prior ideological beliefs about parties and/or candidates. Voters that are ex ante indifferent about the candidates attach little value to information because they perceive that voting itself will have little value. Voters that are ex ante very ideological also attach l…
This article considers manipulation of collective choice — in such environments, a potential alternative is powerful only to the degree that its introduction can affect the collective decision. Using the Banks set (Banks, 1985), we present and characterize alternatives that can, and those that can not, affect sophisticated collective decision-making. Along with offering two substantive findings…
This article develops a model of random matching with costly monitoring to demonstrate that the threat of ethnic conflict can function to create an in-group policing mechanism which helps enforce inter-ethnic social order. Instead of regarding ethnic conflict as a form of collective penalty on an unidentified wrongdoer and his ethnic brethren (Fearon and Laitin, 1996), we argue that ethnic conf…
The topic of nonprofit reform has sparked a debate on the battle between efficiency and effectiveness. Why do ineffective nonprofits survive? Prospective donors favor applicants likely to fulfill donor priorities. Donors with limited time and energy look for signals that reveal recipients' true capabilities. Knowing this, recipients attempt to send the right signals to prospective donors. If th…
I present a formal model of the effect of political representation on the formation of group identities using the drafting of the United States Constitution as a case study. I first show the presence of `factions', or groups with competing interests, to be beneficial in forging a national identity. Next, I use this model to argue that the Great Compromise succeeded as more than a political mane…
Intuition suggests that a fair lottery is the appropriate way to allocate a scarce good when two or more people have equally strong claims to it. This article lays out three conditions that any conception of justice compatible with this intuition must satisfy — efficiency of outcomes, fairness of outcomes, and fairness of treatment. The third, unlike the first two, manifests itself only in the …
