In this paper, the introduction of direct-democratic decision-making in all EU decisions is considered when it is feasible without prohibitively increasing decision-making costs. We start with the contractarian argument that each constitution is a contract joining the citizens of a state and...

Using estimates of support for Leave across UK local authority areas constructed from a comprehensive 20,000 strong survey, we show that both the level and the geographic variation capturing differential degrees of support for Leave have changed significantly since the 2016 EU referendum. A lot...

The additionality principle says that the funds of the European Union should not replace, but be an addition to national regional policy funds. The benchmark for the co-funding is that the EU bears 50% of total costs associated with regional projects eligible for EU support. In some regions,...

We quantify general equilibrium effects of place-based policies in a multi-region framework with mobility, trade and agglomeration economies. Using detailed data on EU transfers, we infer the local effects of different transfer types on productivity, income and transportation cost. Based on...

The paper provides an equilibrium analysis of how countries compete for migrants. The type of competition (tax or transfer competition) depends on whether the competing countries have similar policy preferences. With symmetric preferences, countries compete in taxes for migrants. With asymmetric...

We study fiscal spending by supranational unions, where participation is voluntary and countries bargain over contributions to and the allocation of a central budget. We explore the link between the allocation and nations ́contributions that occurs since bargaining power is endogenous, and...

The vast majority of federations lack exit clauses. Existing theoretical explanations of this stylized fact focus on issues of credible commitment, signaling, and the risk of strategic exploitation. However, such accounts are unable to explain the adoption by the European Union (EU) of Article...

Preferences about the vertical distribution of power in federal systems are not well understood. I argue that negative historical experiences with higher-level governments can plausibly raise demands for exit strategies and a devolution of power. But integration, for instance delegating power...
