The shifting emphasis on performance evaluation and accountability in the context of financial lending or foreign-aid arrangements sponsored by international organizations (IOs) has brought to the fore the question of government ownership of reforms. While the concept of ownership has featured highly in academic and policy debates over the effects...

Recent literature argues that with ever‐increasing levels of supranational constraints governments have less “room to maneuver;” therefore, voters will place less weight on policy outcomes in their voting decisions. The question that remains less explored is how voters fill this accountability gap. We argue that, in this context, voters may move aw...

Despite years of crisis, the euro has enjoyed strong popular support across the Eurozone periphery. In light of the high costs of internal devaluation strategies, this begs the question why the public has remained in favor of the common currency. In this paper, we propose a theoretical mechanism that accounts for both voters’ pocketbook preferences...

How does the prospect of accession to an international union affect a non-member-state government’s incentives to implement political and economic liberalization reforms? To answer this question, we propose an informational mechanism of international union accession conditionality drawing on Bénabou and Tirole’s (The Review of Economic Studies, 70,...

Despite years of crisis, the euro has enjoyed strong popular support across the Eurozone periphery. In light of the high costs of internal devaluation strategies, this begs the question why the public has remained in favor of the common currency.

This article seeks to analyze the political economy of military conscription policy and its relationship with a country’s external security environment. National security is modeled as a non-rivalrous and non-excludable public good, whose production technology consists of either centrally conscripted or competitively recruited military labor. Consc...

In this paper, we examine the relationship between supranational integration and domestic party-system polarization (extremism). We first construct a theoretical argument that uncovers the key trade-off between the “output legitimacy” of a supranationally integrated party system and the inevitable loss of “input legitimacy” caused by externally imp...

When popular referendums fail to ratify new international agreements or succeed in reversing existing ones, it not only affects domestic voters but also creates negative spillovers for the other parties to such agreements. We explore how voters respond to this strategic environment. We use original survey data from a poll fielded just one day befor...

Referenda in Greece and the UK have recently sent shockwaves across Europe. This paper examines this popular challenge to international cooperation in a systematic fashion by focusing on foreign policy referenda in which a non-cooperative vote is associated with large negative externalities. Such high-stakes referenda are unusual because the conseq...

Despite years of crisis, the euro is still enjoying strong popular support in many of the Eurozone crisis countries. Given the high costs that the crisis has imposed on these countries, this raises the question why the public thinks so favorable of the union, and under which circumstances these high support levels may decrease. Using original surve...

This paper examines the endogenous strategic considerations in simultaneously creat-ing, enlarging, and deepening an international union of countries within a framework of variable geometry. We introduce a coalition-theoretic model to examine the equilibrium relationship between union size and scope. What is the equilibrium (stable) size and scope...

Does conditionality always work? If, as it appears, the answer is negative, why do certain externally incentivized countries comply while others do not? To answer these questions we rely on cognitive psychology and dynamic Bayesian principal-agent games to develop a theory of downwards-sloping long-run supply curves. More specifically, we explain h...

What explains a party's dual decision about whether to endorse a referendum on an international treaty and whether to support that treaty in a referendum campaign? Relying on an original game of second-order electoral competition, this article argues that the relative likelihood of a party endorsing a referendum is highest at the beginning and end...

What explains a political party's decision to call for or speak out against a referen-dum on an international treaty? Treating referendums as second-order elections with an uncertain outcome, we propose a probabilistic game of electoral competition between government and opposition. Among the expectations derived from our model are that a party is...

Building on a Condorcetian common-values framework, this paper tackles the question of optimal committee formation within a community of finite size. Solving for the Bayesian information aggregation game yields some interesting normative results that emphasize the presence of informational externalities as root causes of suboptimally low voluntary...

I model the link between political regime and level of diversification following a windfall of natural resource revenues. The explanatory variables I make use of are the political support functions embedded within each type of regime and the disparate levels of discretion, openness, transparency, and accountability of government. I show that a demo...

This paper introduces a new theoretical framework of international unions qua coalitions of countries adopting a common policy and common supranational institutions. I make use of a three-country spatial bargaining game of coalition formation, in order to examine the endogenous strategic considerations in the creation and enlargement of internation...

This paper introduces a new theoretical framework of international unions qua coalitions of countries adopting a common policy and common supranational institutions. We introduce a general class of non-cooperative spatial bargaining games of coalition formation among three countries in order to examine the endogenous strategic considerations in the...

This paper seeks to analyze the political economy of military conscription policy and its relationship with a country's foreign policy outlook (hawkish or dovish). National security is modeled as a non-rivalrous and non-excludable public good, whose production technology consists of either centrally conscripted or competitively recruited labor. Con...
