Determining a GHG emission cap for Colombia under a continuation of the Kyoto protocol = Determinación de un nivel máximo de emisiones de GEI para Colombia bajo una continuación del protocolo de Kioto

Por: Juan Pablo Romero Rodríguez | Fecha: 01/01/2008

This dissertation project assesses the possibility of Colombia becoming an annex I country before 2020. This assessment assumes that the country will eventually have to define the year during which it will be required to start reducing its GHG emissions and by what amount. This project aims to answer the following questions; in which year Colombia should assume a GHG reductions cap? And how much GHG emissions should Colombia reduce?These two questions were answered by first projecting the growth of future emissions of the country based on economic parameters, population growth and energy consumption and secondly by calculating the cost of undertaking the GHG reductions to meet the target. Three separate analyses were performed in order to answer those questions; first a comparative analysis of the country’s conditions when the protocol was signed, second the concept of the Environmental Kunznets Curve was used and confronted with the available Colombian data and third it was necessary to project when Colombia will be responsible for percent of the world’s emission.The results showed that at least until the year 2020 Colombia will not be responsible for a share bigger than one percent of the world emissions; neither will it reach the peak of the EKC and lastly Colombia will not become a higher middle income country anytime before the year 2020. The main conclusion obtained in this dissertation is that Colombia should not undertake any GHG reduction targets under the continuation of the Kyoto protocol before the year 2020.

Risk management: disclosure effects

Por: Juan Francisco; Gutiérrez Diez | Fecha: 01/01/2009

This thesis explores the effect of disclosure on risk management policies. Following recent theory on risk management, with market imperfections, risk management creates value by reducing the volatility of the cash flows. Those risk policies are conditioned by actual disclosure rules that reduce information asymmetry between managers and shareholders, providing a comprehensive view of the firm.However, disclosure gives different accounting choices, hence affecting the decision-making process of managers. The purpose of this thesis is to establish if managers adapt their actual risk policy to disclosure rules. Specifically, we discuss how managers make decisions regarding exchange rate risk in forecasted transactions. In addition, we discuss how hedging affects valuation by using an investor perspective. This is done through the analysis of the automotive industry in Sweden, Germany and France and the considerations of analysts and auditors.We found that risk management policies are affected by accounting rules and that analysts are aware of those effects but have problems to measure them. However, not enough evidence was found to prove that managers try to avoid the volatility the fair value option brings when hedging a forecasted flow.

The perceptions of monoligual spanish parents towards their daughters’ learing process of acquiring a second language and their ideas on how we, as a school can help them through this process

Por: Ana María Rojas Nariño | Fecha: 01/01/2009

This research investigated how monolingual Spanish speaking parents perceived their involvement during their daughters’ second language acquisition process, and what they believed the school should do to help them help their daughters. The researcher contacted 25 parents who live in Bogotá- Colombia and then administrated a questionnaire via email.It was found that: (1) Parents want to raise bilingual children in order to prepare them for the future but, (2) their low proficiency level in the second language is the main barrier to be 100 percent involved during the SLA process (3) Parents believe that in order for their daughters to be successful not only in acquiring a second language, but during their school life, both school and parents need to work as a team (4) Mothers, which according to the findings have the lowest proficiency in the second language, are the ones having to help their daughters at home with homework, and therefore the SLA process, adding an extra stress to their everyday household activities (5).The parents of this study know exactly want they want the school to teach them in order to feel proficient when helping their daughters, for that reason, the school needs to take the necessary steps to motivate, support and guide parents to be involved and effective when it comes to helping their daughters learn. Excerpts in both English and Spanish, are presented throughout the research. At the end, limitations of this research and recommendations for future research are stated.

Trade Liberalization and Food Security: The Case of Bolivia after the Structural Reforms of 1985 = Liberalización comercial y seguridad alimentaria: el caso de Bolivia luego de las reformas estructurales de 1985

Por: Mauricio Giovanni Valencia Amaya | Fecha: 01/01/2009

This research shows the relationship between trade liberalization and food security for the Bolivian case. As a result of the severe economic crisis of the early-1980s, Bolivia adopted a series of market-oriented reforms in 1985. The reforms included the liberalization of the trade regime and the promotion of non-traditional exports. The trade liberalization had an important effect on the performance of cash crops, especially in the development of the soybeans industry. However, food crops did not have such a great dynamics. Vegetables and starchy roots declined in per capita terms and the increase in imports were not enough to compensate the decline. Trade reforms mostly favor a small group of large-scale farmers in the lowlands, who had historically been granted land in the region. In this sense, Bolivia’s involvement in a trade liberalization process has not been reflected in an overall improvement of the country’s food security.

Educación y Cuidado de la Primera Infancia: un Análisis Económico = Early Childhood Education and Care: an Economic Analysis

Por: Rocío Vera Llanos | Fecha: 01/01/2009

This thesis considers the most current knowledge of the importance of investing in early childhood education and care (ECEC) programs with a focus on the economic benefits: higher rate of returns to education, higher productivity, lower crime rates, higher government savings and breaking up intergenerational poverty. Although the evidence suggests significant short-term effects in terms of educational benefits (e.g. lower repetition rates and special education), the empirical evidence for the economic benefits is still not as significant as it is desirable for their generalization. Therefore, it shows the need for more reliable information to construct a stronger argument leading governments to decide ipso facto increasing the educational expenditures in early childhood education programs.

‘Under the colombian flag’: nation-building on San Andrés and Providence islands, 1886-1930

Por: Sharika DeShawn Crawford | Fecha: 01/01/2009

Under the Colombian Flag examines the Colombian state‘s efforts to incorporate the Afro-Caribbean English-speaking Protestant islanders of San Andrés and Providence into the Spanish-speaking Catholic nation. The project analyzes how those cultural struggles and political negotiations shaped the Colombian nation-building process. I illustrate how Colombian political elites largely spoke of islanders‘ ethnic differences in terms of cultural attributes such as language, religion, and customs. In their minds, these characteristics were malleable. The Colombian nation-builders‘ project thus ignored North American and European pseudo-scientific understandings of race in order to incorporate ethnically and racially diverse populations into their homogenizing agenda, which promoted the Spanish language, Hispanic culture, Roman Catholicism, gendered notions of morality, and racial views of health and modernity. San Andrés and Providence islanders had a different understanding of racial and national identities. They tended to formulate their Colombian identity in terms of loyalty, reciprocity, and rights. My work contributes to the growing body of historical scholarship on race and nation-building in Latin America and the Caribbean as well as scholarship investigating the experiences of black communities in the Atlantic world.

Policy Recommendations To Foster The Development Of The Vegetables Supply Chain In An Agrarian District = Recomendaciones de Políticas para Impulsar el Desarrollo de un Clúster Agrícola en un Distrito Agrario en Antioquia

Por: Yúber Andrés Romero Aristizábal | Fecha: 01/01/2009

Oriente Antioqueño is an important region within Antioquia. There, the production of vegetables represents an important element of the economy, with approximately 12,000 farmers cultivating vegetables in four municipalities. There, farmers have inadequate training in agricultural practices, they lack adequate instruction on how to use fertilizers and pesticides, and also they do not have the appropriate instruments, among many other technological pitfalls. This situation leads to high levels of crops losses, higher costs of production, and sometimes, noncompliance with phytosanitary standards and environmental damage.In order to solve the problem this thesis analysis the outcome from central policies and covers the analysis of two international cases (in Brazil and Nicaragua) looking for new strategies to foster competitiveness in the production of vegetables.I identified four policy options: (1) maintaining the status quo, (2) increasing municipal revenues and restructuring UMATAs, (3) upgrading Law 811, and (4) implementing a cluster development program. The first alternative assesses the implications of letting the market operate under current conditions.Policy alternatives 2 and 3 evaluate the benefits from restructuring agricultural extension offices and the agreements of competitiveness. Finally, implementing a cluster development program explores the gains from creating a local strategy to generate an enabling environment in the production of vegetables. After evaluating the policy options using the criteria of political feasibility, administrative feasibility, effectiveness, efficiency, and equity, I recommend implementing a cluster development program. This option is likely to generate higher benefits as it counteracts problems in the supply and the demand side of the vegetables supply chain. Moreover, as a program implemented at the local level by local institutions, it promises better results.

Option-implied volatility and credit announcements: an event study approach = La volatilidad implícita en opciones y anuncios de crédito: estimacion via estudio de eventos

Por: Nicolás Salamanca Acosta | Fecha: 01/01/2009

The aim of this paper was to measure the effect of different credit-related events on the option implied volatility of several companies that belong to the Dow Jones Euro Stoxx 50 index list. Measuring the effect of credit events on volatility will augment on the already important body of literature that investigates the volatility-related phenomena; in particular those who research the effect of news on volatility.I find that, over the entire window around the credit events, there was a decrease in the implied volatility but that only the negative events have a statistically significant effect, which reflects the stronger information content of negative credit events researched by previous papers. I also found that this negative effect is mainly due to a strong “reversal” effect in the post-event 10-day period, where the negative effect is stronger and more statistically significant (particularly for the negative events).Furthermore, during the pre-event period there is not much evidence that supports any type of foresight of the market. My results also suggest that there is a difference between the behavior of the implied volatility when the events are outlook changes and credit reviews, and when the event is a rating change (downgrade/upgrade).

Coupling level set methods with the ensemble kalman filter for conditioning geological facies models to well and production data

Por: David Leonardo Moreno Bedoya | Fecha: 01/01/2009

In the work we developed a new methodology based on the ensemble Kalman filter (EnKF) and the level set method for the continuous model updating of geological facies with respect to production and static (well logs) data. We modelled geological facies using a level set representation and further conditioned them to production and static data using the ensemble Kalman filter. The history matching was done in a continuous fashion since the filter does not depend on previous states and updates parameters and states of the physical system as it receives data from the fields. The methodology is completely new and may provide an alternative to the pluri-Gaussian method with competitive complexity times. Further, the methodology allows to involve prior knowledge of the reservoir as a template base case in a Bayesian-like update. The methodology was tested and compare to others and implemented on a real 3D north-sea and synthetic reservoirs.

Brain-machine interface for decoding imaginary limb movements = Interface cerebro computador para la decodificación de movimientos imaginarios

Por: Anderson Mora Cortés | Fecha: 01/01/2009

In this thesis two different studies are presented separately because each study has a different purpose even though the two studies are complementary. For the first study an available dataset for BCI is used. This dataset is consistent with the aim of the first study because it allows the implementation and development of the proposed technique for BCI based on imaginary limb movement with a small amount of electrodes. The technique I implemented trough this study is a reliable option to be used for a BCI-based on imaginary movements.In the second study a different dataset is used because the requirements for the technique to be implemented are different. Training and testing dataset are necessary to describe a practical computational technique that is applied for a single trial classification based on a Common Spatial Pattern and complemented with a linear discriminator. The training data is used to build a classifier and the testing data allows measuring the performance of the classifier implemented. After testing the classifier the good performance obtained makes this technique of great interest for any imaginary movement based-BCI.
