Growing interest in inequality has generated an outpouring of scholarly research and has brought many discussions on the subject into the public realm. Surprisingly, most of these studies and discussions rely on a narrow set of indicators to measure inequality. Most of the time a single summary measure of inequality is considered: the Gini coefficient. This is surprising not only because there ...

We construct a model of wealth distribution, based on an interactive multiplicative stochastic process on static complex networks. Through numerical simulations we show that a decrease in the number of links discourages equality in wealth distribution, while the rewiring of links in small-world networks encourages it. Inequal distributions obey log-normal distributions, which are produced by we...

At the basic RF-channel level, DRM shares many characteristics with other modern systems such as DVB-T and DAB. It utilises Coded Orthogonal Frequency Division Multiplexing (COFDM) [1][2] to combat noise, narrowband fading and multipath. Broadcasts can be synchronized to support Single-Frequency Networks (SFNs) and Multi-Frequency Networks (MFNs). One DRM service normally occupies one AM channe...

Emigrants moving from poor to rich countries experience large income gains on average. These gains are further augmented by remittances that allow a portion of the gains to be spent at lower sending-country prices. Taking advantage of recently available estimates of emigration-related income gains, this paper estimates the direct impact of international migration on the world income distributio...
