This paper describes the equilibrium price function generated by brokers in a market in which heterogeneous buyers meet heterogeneous sellers through a matching process with frictions. The equilibrium price function relates the price to alternative ratios of buyers and sellers offered by different brokers. The paper shows how brokers can enter a matching market and charge fees that yield a prof...

We present a selective neighbor caching approach for supporting mobility in publish/subscribe networks. According to the approach, a mobile’s subscriptions are transmitted to a subset of brokers that are neighbors of the current broker that the mobile is connected to. Our key contribution is the definition of a target cost function and an intelligent procedure for selecting the subset of neighb...

Lamb carcass value is widely reported to be a function of lean meat yield, which is the relationship between muscle, fat and bone. Five retailers and five wholesalers assessed 47 lamb carcasses from diverse genotypes and scored seven attributes. A hedonic model reveals that conformation attributes were more highly valued (16 c/kg) relative to yield characteristics (4 c/kg). Meat colour and fat ...

In this paper I critically discuss the pros and cons of working with research brokers from a political science perspective. do by sharing my experiences collaborating two types local “fixers” – cultural communal brokers. argue that even if similar approaches risk introducing number broker-induced biases, countermeasures can be taken to mitigate their effect: e.g. continuous triangulation, inter...

Abstract Data brokers share consumer data with rivals and, at the same time, compete them for selling. We propose a ‘co-opetition’ game of and characterize their optimal strategies. When are ‘sub-additive’ merged value net merging cost being lower than sum values individual datasets, more likely to sell jointly. ‘super-additive’, greater competition emerges often. Finally, sharing is when effic...
