Cooperation among firms can be analyzed from different theoretical perspectives. The objective of this paper is to analyze firm networks from the perspective of team theory and club theory. Even though these theories are not recent in economics, using them as a theoretical framework for the characterization of firm networks could be a novel contribution. We can infer that aspects of both theories could be combined to explain cases of cooperation. [ABSTRACT FROM AUTHOR]

Some nations criticize Colombian efforts to fight against the violence. However, Colombia doesn't have real support from some of its neighbors (Nicaragua, Ecuador and Venezuela) as well as other actors to combat guerrillas or paramilitary groups which, in turn, are related to the drug traffic. It is necessary that the international community understand the Colombian effort to carry out its struggle against ilegal drugs as well as the violence that results there from. Colombia has increased its spending in Security and Defense during the last decade especially against narcotrafficking. Does Colombia have real support from its neighbors and allies to combat this crime? This paper evaluates the cooperation that Colombia has obtained from other actors in this struggle not only in economic terms, but also in terms of institutional support. [ABSTRACT FROM AUTHOR]

This paper seeks to illustrate different approaches to collective action and their relation with particular types of public policy. We analyze the impact of econonomics and non-economics collective action driven perspectives on public policy theory. The former perspective is conducive to a rational approach to policy. However, as reciprocity enters into collective action reasoning, then public policy becomes interested in understanding behavioural change in terms of such relations. Finally, we conclude on the relevance of collective action for the study of public policy and highlight the circumstances that may foster such analysis. [ABSTRACT FROM AUTHOR]
