The “War on Terror” and the Principle of Distinction in International Humanitarian La

Este artículo investiga el impacto de la guerra del terror en el principio de distinción en el derecho internacional humanitario.

Equilibrium Principle in Colombian Public Contracting

Public contracting in Colombia is conflicting and inefficient. It frequently leads to damage to State property. The Colombian legal system cannot assure efficient and transparent public contracting. The cause is the institutional environment characterized by high transaction costs. Colombian law worsens the process by recognizing the principle of economic equilibrium in public contracts. This principle increasese contract incompleteness and renders impossible the use of economic incentives to control the opportunism of the economic agents. The authors present the hypothesis that the economic equilibrium principle increases the conflictive nature of public contracting. They test the hypothesis empirically. The first section of the paper presents a summary of the literature on transaction costs economics, as well as the legal literature on the historical origin and the content of the economic equilibrium principle. The second section describes the methodology of the empirical study. The third section shows the empirical evidence of the effects that the economic equilibrium principle exerts over the public contracting. The last section presents the conclusions.

Decoding the canada's foreing and security policy: tracking the strategic and ethicliberal approaches of a middle power's behavior

The article attempts to explain the main paradox faced by Canada at formulating its foreign policy on international security. Explained in economic and political terms, this paradox consists in the contradiction between the Canadian ability to achieve its strategic goals, serving to its own national interest and its dependence on the United States. The first section outlines three representative examples to evaluate this paradox: the Canada’s position in North American security regime, the US-Canada economic security relations, and the universe of possibilities for action of Canada as a middle power. The second section suggests that liberal agenda, especially concerning to ethical issues, has been established by this country to minimize this paradox. By pursing this agenda, Canada is able to reaffirm its national identity and therefore its independence on the United States. The third section evaluates both the explained paradox and the reaffirmation of Canadian identity during the Jean Chrétien (1993-2003), Paul Martin (2003-2006) and Stephen Harper’s (2006) governments.
