T he measurement of family budgets and budget standards dates back to the late 19th c...

We study online auction settings in which agents arrive and depart dynamically in a random (secretary) order, and each agent’s private type consists of the agent’s arrival and departure times, value and budget. We consider multi-unit auctions with additive agents for the allocation of both divisible and indivisible items. For both settings, we devise truthful mechanisms that give a constant app...

Personal health budgets (PHBs) were piloted in the National Health Service (NHS) in England between 2009 and 2012 and were found to have greater positive effects on quality of life and psychological well-being for those with mental health problems than commissioned service, as well as reducing their use of unplanned care. The government intends to extend PHBs in England for long-term conditions...

Climate change is one of the greatest threats to the long-term maintenance of coral-dominated tropical ecosystems, and has received considerable attention over the past two decades. Coral bleaching and associated mortality events, which are predicted to become more frequent and intense, can alter the balance of different elements that are responsible for coral reef growth and maintenance. The g...

We consider budget constrained combinatorial auctions where bidder i has a private value vi for each of the items in some set Si, agent i also has a budget constraint bi. The value to agent i of a set of items R is |R ∩ Si| · vi. Such auctions capture adword auctions, where advertisers offer a bid for those adwords that (hopefully) reach their target audience, and advertisers also have budgets....

19 Coral reefs play a critical role in coastline protection and support fisheries and tourism. Maintaining 20 these ecosystem services requires, as a minimum, positive biological carbonate budgets, whereby 21 rates of carbonate production exceed erosion. Coral bleaching and associated mortality events, 22 which are predicted to become more frequent and intense, can rapidly diminish carbonate 23...
