In this paper, we ask how antitrust immunity subject to a carve-out affects collusion incentives in international airline alliances. We show that the gains from economies of density due to higher interline traffic under the alliance strengthen the incentive to collude on the interhub segment,...

This paper shows that the inefficiency of fiscal decentralization in the presence of spillovers, a main tenet of the decentralization literature, is overturned in a particular transportation context. In a monocentric city where road (bridge) capacity is financed by budget-balancing user fees,...

This paper extends the small existing theoretical literature on negative campaigning, building on work by Harrington and Hess (1996). While their analysis explores the determinants of negative campaign spending using a classic spatial voting model, this paper relies instead on a probabilistic...

This paper extends a new line of research on urban squatting that focuses on the role of the squatter organizer. The model replaces the benevolent organizer from previous studies with a collection of competing, rent-seeking squatter organizers, a structure that may offer a realistic picture of...

Much of the literature on the economics of mortgage markets has studied the FRM-ARM choice made by individual borrowers. However, to decide if the outcome of such a choice is efficient or approximately so, it is necessary to explore the question of optimal risk-sharing in mortgage contracts. But...

This paper provides an empirical test of a principal tenet of fiscal federalism: that spending discretion, when granted to localities, leads to public-sector heterogeneity, with public-good levels adjusting to suit local demands. The test is based on a simple model of partial fiscal...

This paper provides theory and evidence on airline bag fees, offering insights into a real-world case of product unbundling. The theory predicts that an airline’s fares should fall when it introduces a bag fee, but that the full trip price (the bag fee plus the new fare) could either rise or...

This paper analyzes cordon tolling using a simple model where space is discrete rather than continuous, with commuting costs incurred only on two congested bridges. The first-best regime requires tolls on both bridges, whereas only the inner bridge is tolled under the cordon-toll regime. While...
