We will review some of the major results in random graphs and some of the more challenging open problems. We will cover algorithmic and structural questions. We will touch on newer models, including those related to the WWW.

Random graphs

The paper is concerned with spatial clustering of economic activity and its relation to the spatiality of knowledge creation in interactive learning processes. It questions the view that tacit knowledge transfer is confined to local milieus whereas codified knowledge may roam the globe almost frictionlessly. The paper highlights the conditions under which both tacit and codified knowledge can be exchanged locally and globally. A distinction is made between, on the one hand, the learning processes taking place among actors embedded in a community by just being there dubbed buzz and, on the other, the knowledge attained by investing in building channels of communication called pipelines to selected providers located outside the local milieu. It is argued that the co-existence of high levels of buzz and many pipelines may provide firms located in outward-looking and lively clusters with a string of particular advantages not available to outsiders. Finally, some policy implications, stemming from this argumen...

Clusters and knowledge: local buzz, global pipelines and the process of knowledge creation

The author systematically examines one of the important issues of information — establishing the market price. He introduces the concept of «search» — where a buyer wanting to get a better price, is forced to question sellers. The article deals with various aspects of finding the necessary information.

Social Network Analysis

The 2008 crash has left all the established economic doctrines - equilibrium models, real business cycles, disequilibria models - in disarray. Part of the problem is due to Smith’s "veil of ignorance": individuals unknowingly pursue society’s interest and, as a result, have no clue as to the macroeconomic effects of their actions: witness the Keynes and Leontief multipliers, the concept of value added, fiat money, Engel’s law and technical progress, to name but a few of the macrofoundations of microeconomics. A good viewpoint to take bearings anew lies in comparing the post-Great Depression institutions with those emerging from Thatcher and Reagan’s economic policies: deregulation, exogenous vs. endoge- nous money, shadow banking vs. Volcker’s Rule. Very simply, the banks, whose lending determined deposits after Roosevelt, and were a public service became private enterprises whose deposits determine lending. These underlay the great moderation preceding 2006, and the subsequent crash.

Unleashing the potential of relational research: A meta-analysis of network studies in human geography:

This article integrates arguments from the perspectives of the economics of information and of the economy of qualities to analyze the spatial consequences of digital technology and information overload on two exemplary product markets: quality wine and stock photography. It demonstrates how digital technology enhances information overload in product markets and how the geography of market relations is transformed along new intermediaries and new practices of navigation that account for two different geographical paradoxes.

Information overload, navigation, and the geography of mediated markets

Das Netzwerk ist zu einem Schlusselkonzept der wirtschaftlichen Zusammenarbeit zwischen Unternehmen geworden. In den letzten drei Jahrzehnten haben Unternehmen infolge vertikaler Desintegration (Scott 1988), flexibler Spezialisierung (Storper und Christopherson 1987; Piore und Sabel 1984) und erhohten Innovationsdrucks zunehmend Kooperationsbeziehungen mit anderen Unternehmen aufgebaut, um Ressourcen auserhalb des eigenen Unternehmens zu erschliesen und somit die eigene Wettbewerbsfahigkeit zu sichern oder zu steigern. So entstanden Formen des wirtschaftlichen Austauschs, die weder durch Preiswettbewerb noch durch Unternehmenshierarchien koordiniert werden. Diese Formen der zwischenbetrieblichen Zusammenarbeit werden allgemein unter dem Begriff des Unternehmensnetzwerks zusammengefasst, der seit den 1980er Jahren zunehmend in den Fokus der wissenschaftlichen Diskussion geriet (Galaskiewicz 1985). Die wiederholte und dauerhafte Zusammenarbeit von Unternehmen entzieht sich dem Verstandnis des am Markt herrschenden Preiswettbewerbs einerseits und der hierarchischen Autoritat andererseits (Powell 1991).
