In this paper we perform a simulation procedure of testing models for journeys to work. The testing regime is carried out on a number of such models, mainly within the class of gravity models. We test the models on synthetic populations constructed from an aggregated set of a large number of...

Large-scale models are often used in the urban planning context to model the effects of, for instance, a change in land-use policies or transportation infrastructure. This class of models accounts for factors such as the spatial distribution of jobs and workers, commuting flows, housing markets,...

Combinatorial auctions permitting bids on bundles of items have been developed to remedy the exposure problem associated with single-item auctions. Given winning bundle prices a set of item prices is called market clearing or equilibrium if all the winning (losing) bids are greater (less) than...
