IZA Discussion Paper No. 912

An Experimental Study of the POUM Hypothesis The “prospect of upward mobility” (POUM) hypothesis formalised by Benabou and Ok (2001a) finds explicit assumptions under which some individuals that are poorer than the average optimally choose to oppose redistribution policies. The underlying intuition is that these individuals rationally expect to be richer than average in the future. This result ...

Movable (n4) Configurations

An (nk) configuration is a collection of points and straight lines, usually in the Euclidean plane, so that each point lies on k lines and each line passes through k points; such a configuration will be called symmetric if it possesses non-trivial geometric symmetry. Although examples of symmetric (n3) configurations with continuous parameters are known, to this point, all known connected infin...

Virtual Queueing Techniques for ABR Service: Improving ABR/VBR Interaction

Several algorithms have been proposed for the switch behavior for congestion control of Available Bit Rate (ABR) services. Schemes such as the Enhanced Proportional Rate Control Algorithm (EPRCA) and the Dynamic Max Rate Control Algorithm (DMRCA), which use the queue length as congestion indicator to make a simple approximation of the fair share converge to the actual fair share, have become po...

ABR Engineering: Roles and Guidelines for Setting ABR Parameters

This paper discusses the role of parameters negotiated and used for ow control in the ATM ABR service, and gives guidelines for setting each parameter. The e ect of the speed of the links on the path from the source to the destination, and the round trip time of the connection, on the ABR parameter values is discussed. We also give simulation results to illustrate the e ect of various parameter...
