International Law as a Source of Constitutional Law

This article has the purpose to prove that the Customary International Law and the Conventional International Law are sources of Constitutional Law. First, it analyses the matter of the relations between International Law and National or Domestic law according with the theories dualism and monist and international decisions. Then, it studies the reception and the hierarchy of International Customary and Conventional Law to Domestic Law including Constitution. This matter has been studied according with several Constitutions and the international doctrine. Then, it considers the constitutional regulations about international law in the Constitution of the Republic of Colombia. The general conclusion is that International Law is incorporated in domestic law according with the Constitution of each country. But every state has the duty to carry out in good faith its obligations arising from treaties and other sources of International Law, and it may not invoke provisions in its Constitutions or its Laws as an excuse for failure to perform this duty. Accordingly, state practice and decided cases have established this provision, and the same rule is established in articles 27 and 46 of the Vienna Convention on Law of Treaties of 1969.

The communication by States of International Law to their direct stakeholders

El derecho internacional fue concebido como un derecho interestatal. Sin embargo, como consecuencia del desarrollo progresivo del derecho, nuevos actores y nuevos sujetos han ido surgiendo. El individuo es uno de ellos bajo diferentes perspectivas, bajo la perspectiva penal al asumir la responsabilidad de sus actos frente a los diferentes tribunales ad hoc y, ahora ante la Corte Penal Internacional. También se ha desarrollado la figura bajo la perspectiva de los derechos humanos. Este artículo analiza las formas como las políticas estatales relativas al derecho internacional se presentan a los individuos, a las personas jurídicas y a los demás actores.

“Superficial Water Concessions In Light Of The General Theory of the Administrative Act” The Incidence of the Public Law’s Dogmatic Tradition of Public Law Within Environmental Law

This paper seeks the determine the ways in which anomalous decisions derived from the particularization and constitutionalization of environmental law can arise given the general theory of administrative action. This is seen through the lens of a study and characterization of administrative decisions issued by the Regional Autonomous Corporation of Cundinamarca –CAR- within the superficial water concessions procedure. It also discusses the conceptual contents of these licenses.

A sociological view of family law in Colombia. Radicalism-1945

This paper affirms that the economic and political failure of the Radical Period provided opportunities for those who proposed Regeneration as a means of defending authority. Family law became an important tool in that process. During the period studied by this article, the equality clause remained in Colombian constitutions without any practical affect for the majority of the people. Discrimination was imposed through family law over those who had born outside of a Catholic marriage and/or had not previously legitimized their union through a Catholic ceremony. By the middle of the 20th century, the dramatic situation of the nation’s children led to efforts to change the social prejudices through legislation, that is, in the same way the prejudices had been imposed.

A Network model of systemic risk : identifying the sources of dependence across institutions

We design a financial network model that explicitly incorporates linkages across institutions through a direct contagion channel, as well as an indirect common exposure channel. In particular, common exposure is setup so as to link the financial to the real sector. The model is calibrated to balance sheet data on the colombian financial sector. Results indicate that commercial banks are the most systemically important financial institutions in the system. Whereas government owned institutions are the most vulnerable institutions in the system.

Energy saving innovations, non-exhaustible sources of energy and long-run: what would happen if we run out of oil?

We formulate and solve a model of factor saving technological improvement considering three factors of production: labor, capital and energy. The productive activities have three main characteristics: first, in order to use capital goods firms need energy; second, there are two sources of energy: non-exhaustible and exhaustible; third, capital goods can be of different qualities and the quality of these goods can be changed along two dimensions -reducing the need of energy or changing the source of energy used in the production process. The economy goes through three stages of development after industrialization. In the first, firms make use of exhaustible energy and the e¢ ciency in the use of energy is constant. In the second stage, as the price of energy grows the e¢ ciency in its use is increased. In the third stage, the price of exhaustible sources is so high that firms have incentives to use non-exhaustible sources of energy. During this stage the price of energy is constant. In this set up, the end of the oil age has level effects on consumption and output but it does not cause the collapse of the economic system.

Energy Saving Innovations, Non-Exhaustible Sources of Energy and Long-Run: What Would Happen if we Run Out of Oil?

Se formula y resuelve un modelo de cambio tecnológico ahorrador de factores de producción que considera tres factores: capital, trabajo y energía. El modelo cuenta con características específicas con respecto a la interacción n entre la energía (la cual, de acuerdo a su fuente puede ser renovable y no renovable) y el capital. Una vez esta economía se ha definido, se supone que evoluciona en tres etapas luego de su industrialización, durante las cuales el carácter renovable o no renovable de la energía influye su precio relativo, eficiencia y afecta también el nivel agregado de consumo y producción de la economía, sin que esta evolución lleve al colapso del sistema económico.
