This issue contains several papers covering broad areas within political economy, ranging from the effects of private information in lobbying and international conflict to the role of uncertainty and political turnover on policy stability; from the origins and source of partisan cohesion and delegation in legislatures to the political economy of military conscription and inequality. These six articles jointly represent the type of substantively engaged, applied theoretical work that we seek to publish in JTP.In 'Subpoena power and informational lobbying,' Dellis and Oak develop a model in which interest groups seek access to attention-constrained policymakers in order to provide verifiable evidence. They show that if the policymaker is unable to implement policy change on all issues, then he or she is made better off by having subpoena power. However, if the policymaker has unconstrained power to implement policy change, then he or she can be made worse off by having subpoena power, because possession of subpoena power alters the amount of information voluntarily provided by interest groups through lobbying.In 'War and diplomacy on the world stage: Crisis bargaining before third parties,' Scott Wolford analyzes a three-actor model of crisis bargaining in which diplomatic opposition by the third party can raise the costs of war and, while an 'informed' state can avoid such increased costs by conveying restraint during the crisis, the means of conveying restraint may lead the other disputant to doubt the 'restrained' state's willingness to fight and thereby lead to conflict. In this setting, Wolford demonstrates that the probability of conflict is higher when the third party believes the informed state to be generally restrained. In addition, when diplomatic opposition modestly affects the cost of war, bluffing is made less attractive. Finally, when diplomatic opposition greatly increases the cost of war, disputants
