Labor market flows in the cross section and over time [PDF]

Journal of Monetary Economics, 2012
Many theoretical models of labor market search imply a tight link between worker flows (hires and separations) and job gains and losses at the employer level. We use rich establishment-level data to assess several theoretical models and to study the relationship between worker flows and jobs flows.

Generalized Maximum Flows over Time

2012
Flows over time and generalized flows are two advanced network flow models of utmost importance, as they incorporate two crucial features occurring in numerous real-life networks. Flows over time feature time as a problem dimension and allow to realistically model the fact that commodities (goods, information, etc.) are routed through a network over ...

Nash flows over time

2020
Motivated by the dynamic traffic assignment problem and with the goal in mind to obtain a better understanding of the complex traffic dynamics, we consider a dynamic game in a flow over time model with deterministic queuing in this thesis. The dynamic equilibria, called Nash flows over time, in the base version of this model were introduced by Koch and

Time-Dependent Viscous Flow over a Circular Cylinder

The Physics of Fluids, 1969
A finite difference method is extended to high Reynolds number flow about circular cylinders with particular emphasis given to the quantitative description of fine flow features. The method is of the explicit type and includes a directional difference scheme for the nonlinear terms which enhances calculational stability at high Reynolds numbers. A cell

Existence and Uniqueness of Equilibria for Flows over Time

2011
Network flows that vary over time arise naturally when modeling rapidly evolving systems such as the Internet. In this paper, we continue the study of equilibria for flows over time in the single-source single-sink deterministic queuing model proposed by Koch and Skutella.

Flows Over Time with Flow-Dependent Transit Times

2003
Transportprobleme werden in der Kombinatorischen Optimierung üblicherweise mit Hilfe von Netzwerkflüssen modelliert. Das klassische Flussmodell ist jedoch statisch und reflektiert daher nur unzureichend die zeitliche Komponente eines Transportproblems. Ein spezielles Transportproblem entsteht bei der Straßenverkehrslenkung.

A Survey on Models of Flows over Time with Flow Dependent Transit Times

Prāgyik Prabāha
Ford and Fulkerson introduce the maximum dynamic flow problems with fixed transit times on the arcs and developed the first well known algorithm that sends maximum flow from the source to the sink by augmenting along s-t paths and prove the maximum amount of flow is equal to the total capacity of the arcs in minimum cut.
