Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

In a relatively recent paper, Gehrig and Stenbacka (Eur Econ Rev 51, 77-99, 2007) show that information sharing increases banks' profits to the detriment of creditworthy entrepreneurs in a model of a banking duopoly with switching costs and poaching. They restrict their analysis to the case in...

The division problem consists of allocating a given amount of an homogeneous and perfectly divisible good among a group of agents with singlepeaked preferences on the set of their potential shares. A rule proposes a vector of shares for each division problem. Most of the literature has...

The article proposes an enabling mechanism for the creation, adjustment and dissolution of governmental units, giving autonomy to each individual as in a direct democracy. The mechanism is designed such that Pareto optimality is possible, in contrast to earlier models which make various...

Putting the high public debt ratios on a downward path after the surge during the pandemic and allocating sufficient resources to deliver on the green and digital transition will be among the priorities confronting the EU institutions emerging from the June 2024 European elections. After a long...

The procurement of transportation services via large-scale combinatorial auctions involves a couple of complex decisions whose outcome highly influences the performance of the tender process. This paper examines the shipper's task of selecting a subset of the submitted bids which efficiently...

The introduction of genetically modified (GM) crops in the mid 1990s appeared to be the latest in a string of technological innovations in agriculture. However, consumer resistance, particularly in Europe has limited the sector's enthusiasm. One response to the limited enthusiasm has been the...

We develop a new approach for the identification of Pareto‐improving tax reforms. This approach yields necessary and sufficient conditions for the existence of Pareto‐improving reform directions. A main insight is that “Two brackets are enough”: When the system cannot be improved by...
