We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through linked locations, and transport costs depend on congestion and on the...

Longitudinal network data are increasingly available, allowing researchers to model how networks evolve over time and to make inference on their dependence structure. In this paper, a dynamic latent space approach is used to model directed networks of monthly interbank exposures. In this model,...

One of the most challenging jobs that any managers take is the management of projects that require coordinating numerous activities throughout the organization. A myriad of details must be considered in planning how to coordinate all these activities, in developing a realistic schedule, and then...

Ohne weitere Effizienzsteigerungen sind Krankenhäuser in Deutschland langfristig weder dem finanziellenDruck noch den Herausforderungen des demographischen Wandels gewachsen. Zur Unterstützung von Ressourcenkapazitätsentscheidungen auf strategischer, taktischer und operativer Ebene wird in...
