Bargaining and Incentive Compatibility: A Pareto Frontier Approach.

Two agents negotiate, according to the Nash bargaining solution, over the allocation of a single (divisible) commodity (or multiple commodities with fixed ordinal preferences). It has been shown that in this situation agents find dominant to report their least risk averse utility functions. This result depends crucially on the fact that in this kind of "distortion game", agents have been restricted to report risk-averse utility functions. This paper studies the distortion game originated when agents are also allowed to claim non risk-averse utility functions. Contrasting with previous literature, we find multiple Nash equilibria, multiple payo outcomes and the existence of a first-mover advantage.

An Extension of the Core solution Concept.

A solution concept for cooperative games, the extended core, is introduced. This concept is always nonempty yet coincides with the core whenever it is nonempty. Moreover, a non-cooperative framework can generate the extended core. Every transferable utility game is associated with a two-player zero-sum non-cooperative game. The min-max values of the associated zerosum games characterize when cooperative games have nonempty cores. If the core is empty, the min-max value determines how an exogenous regulator can impose costs on proper coalition formation so that there are no incentives to deviate from extended core imputations, which are necessarily feasible in the original game. In order to choose among the imputations belonging to the extended core, a proportional version of the nucleolus is proposed as a selection device.

Book review. Principles of negotiating international business: Success strategies for global negotiators

This article provides a review of the book “Principles Of Negotiating International Business: Success Strategies for Global Negotiatiors” written by Lothar Katz, and published in 2008 by BookSurge Publishing in Charleston. Globalization has forced companies to become worldwide players in an environment where boundaries for business merely exist. In this limitless world, business people are exposed in an everyday basis to situations where knowing how to negotiate can make the difference between success and failure. In order to succeed, individuals need to face this challenge with the proper knowledge and skills, and even though the negotiation process and its related techniques is a field widely documented, the complexity that the cultural component provides to this process, is sometimes not taken into account or not given the place it deserves

Derivative Markets' Impact on Colombian Monetary Policy

Derivatives are contingent claims that complete financial markets. Their use allow agents and firms to ameliorate the impact over con- sumption, production and investment given a change in relative prices induced by an active monetary policy. In this sense, derivatives gene- rate in some cases a loss in the effectiveness of the traditional monetary transmission channels in the short run, and in others, they promote an increase in the speed of transmission itself. Using an investment model, the impact of the use of interest rate and exchange rate derivatives in the dilution of colombian monetary channels is verified. Empirical exercises suggest that monetary policy has lost effectiveness in the short run.In spite of the surprise this result may offer given the relative im- matureness of domestic derivative markets, the marginal effect of these instruments appears to be significant, in the face of local financial mar- kets' imperfections. In addition, not only the hedge directly taken by firms with access to this instruments matter; there could be hedging spill-overs whenever commercial banks use derivatives, which allow for a more stable and cheap credit supply for firms with no access to those markets. The natural recommendation deriving from this conclusion suggests an urgent analysis of the derivatives impact over the speed of monetary transmission in Colombia.Derivatives; Monetary Policy Transmission Channels;Investment

Estudio de factibilidad de Roto Plásticos S.A.S empresa dedicada a la transformación de plásticos

En el presente trabajo se realiza un estudio de factibilidad para la creación de Roto Plásticos S.A.S donde se tuvo en cuenta un completo estudio de mercados, organizacional, de ingeniería, financiero y económico los cuales fueron desarrollados de forma cuidadosa para así garantizar el éxito de esta idea de comercialización. Los datos obtenidos y posteriormente analizados, sugieren la factibilidad de la creación de la empresa Roto Plásticos S.A.S en las condiciones referidas, teniendo en cuenta como mercado objetivo la ciudad de Pereira. Esta empresa será encargada de la transformación de productos de plástico por medio del proceso de rotomoldeo, la cual en un principio se dedicara a la producción y comercialización de materas luminosas que innovaran el mercado dejando un poco de lado las materas artesanales ya conocidas. Dicho producto se realizara con un proceso poco conocido en Colombia, como también lo es su materia prima, que es el polietileno de media densidad. Este proyecto está enfocado en la ideología de producción limpia que lo que busca es contribuir con la preservación del medio ambiente a través de buenas prácticas de manufactura, la buena utilización de recursos no renovables dándoles un uso mejor después de que se consideran basura, de esta forma se espera que Roto Plásticos S.A.S manejara una cultura de reciclaje y seguirá con su ideología.This work is carried out a feasibility study for the creation of Roto Plasticos S.A.S where it was considered a full market research, organizational, engineering, financial and economic which were developed carefully to ensure the success of this marketing idea. The data obtained and subsequently analyzed, suggest the feasibility of the creation of the company Roto Plasticos S.A.S. conditions concerned, taking into account such as target market the city of Pereira. This company will be responsible for the transformation of plastic products by means of the rotomolding process, which initially was devoted to the production and marketing of light pots that innovate the market leaving a little aside the already known crafts pots. That product was made with a process that is little-known in Colombia, as it is your raw material, which is medium density polyethylene. This project is focused on the ideology of production clean that what search is to contribute to the preservation of the environment through good manufacturing practices, good use of non-renewable giving them resources better use once considered waste, thus expected Roto Plasticos S.A.S to drive a culture of recycling and will continue with their ideology

Memory, Recognition and Solidarity: the Victims of Eastern Antioquia as Communicative Citizens

This doctoral research focuses on the relationship between civil society, collective action and the victims’ social movements of the Colombian armed conflict. It analyses the communicative and expressive dimensions of victims’ collective action as a mechanism to restore a sense of citizenship. It shows how collective belonging is constructed through processes of memory, recognition and solidarity in the midst of armed conflicts. It introduces the concept of communicative citizenship field in which emotions and affection act as a catalyst to generate collective actions for counterpublic groups in armed conflict societies transforming their victim status into an active citizenship condition. The case study of this research is Eastern Antioquia in Colombia, particularly the victims’ social movement of this Colombian region, and through a participative action research approach and developing a set of qualitative strategies, this research explores (together with the studied groups) the communicative and expressive resources they can access to obtain symbolic, cultural and political power and to act effectively within fragile public spheres. A key objective here is to understand what kind of citizen processes these collective communicative actions and strategies can open up within contexts of armed conflict and how these practices have been affecting the structure and shape of the regional and local public spheres of Eastern Antioquia in the last seventeen years. Furthermore, this doctoral research aims to present non-­‐official narratives about the Colombian armed conflict, using the victims’ perspective to understand the dynamics of contestation in the construction of memory, recognition and solidarity during the conflict, as well as in the claiming of public and conflict‐related spaces and the construction of victims’ collective identity as civilians before the cessation of violence. This study finally argues that the communicative citizenship field is part of a new research agenda to better understand, analyse and describe contemporary processes of collective action of victims’ social movements in armed conflicts and post-­‐armed conflict societies
