Colombia has gone from being a producer and exporter of illicit drugs to becoming a country where consumption also plays an important role. In Bogota, as result of specific policies adopted by the authorities that hit illicit drugs hot spots, the sale has gradually become more dispersed. Exacerbated by the emergence of new neighborhoods due to unplanned population growth, monitoring such market...

The growth of electronic-markets (e-markets) necessitates the processing of many commerce protocols (processes). Each protocol handles different messages and flows of transactions among customers, merchants and intermediaries. Developing applications for each commerce protocol is costly and impractical. Accordingly, developing a flexible model of Internet commerce to support various commerce pr...

O commercial interactions have increased dramatically over the last decade, leading to the emergence of networks that link the electronic commerce landing pages of related products to one another. Our paper conjectures that the explicit visibility of such “product networks”can alter demand spillovers across their constituent items. We test this conjecture empirically using data about the copurc...

Buyers' search behaviors on electronic markets are characterized by two distinctive features: i) diminishing search costs and ii) the use of informational intermediaries such as price comparison agents (shopbots). We build a simple agent-based model that captures these two features, and we use this agent-based modeling to explore how the co-evolution of buyers and sellers (i.e. the joint dynami...

One of the major challenges facing the Cloud paradigm is the emergence of suitable economic platforms for the trading of Cloud services. Today, many researchers investigate how specific Cloud market platforms can be conceived and in some cases implemented. However, such endeavours consider only specific types of actors, business models, or Cloud abstractions. We argue that market platforms for ...
