Sustain Cycle

En la búsqueda de preservar el medio ambiente y estandarizar la disposición final de los residuos generados, Sustain Cycle nace como un gestor de residuos de aceite vegetal usado, reforzando la carente oferta del mercado. Fortaleciendo el compromiso de los generadores de este residuo además de una reducción de costos, la creación de Sustain Cycle se desarrolla bajo la figura jurídica de Fundación, deduciendo en los contribuyentes del impuesto el valor de las donaciones efectuadas. El aporte ambiental se basa en minimizar el riesgo de una mala disposición en la red de alcantarillado y su componente social se enfoca en evitar la reutilización ilegal y perjudicial para el consumidor. Sustain Cycle se centra en la recolección, acopio, filtrado y comercialización del AVU generado por todos los establecimientos comerciales que produzcan alimentos como papas a la francesa, empanadas, buñuelos, churros, plátanos y demás productos que requieran del aceite para su cocción.

Business cycle asymmentries: An investment cost approach

In this paper, investment cost asymmetry is introduced in order to test wheter this kind of asymmetry can account for asymmetries in business cycles. By using a smooth transition function, asymmetric investment cost is modeled and introduced in a canonical RBC model. Simulations of the model with Perturbations Method (PM) are very close to simulations through Parameterized Expectations Algorithm (PEA), which allows the use of the former for the sake of time reduction and computational costs. Both symmetric and asymmetric models were simulated and compared. Deterministic and stochastic impulse-response excersices revealed that it is possible to adequately reproduce asymmetric business cycles by modeling asymmetric investment costs. Simulations also showed that higher order moments are insu_cient to detect asymmetries. Instead, methods such as Generalized Impulse Response Analysis (GIRA) and Nonlinear Econometrics prove to be more e_cient diagnostic tools.

Business cycle asymmetries: Loss aversion, sticky prices, and wages

In this chapter, the Smets-Wouters (2003) New Kenesian model is reformulated by introducing the loss aversion utility function developed in chapter two. The purpose of this is to understand how asymmetric real business cycles are linked to asymmetric behavior of agents in a price and wage rigidities set up. The simulations of the model reveal not only that the loss aversion in consumption and leisure is a good mechanism channel for explaining business cycle asymmetries, but also is a good mechanism channel for explaining asymmetric adjustment of prices and wages. Therefore the existence of asymmetries in Phillips Curve. Moreover, loss aversion makes downward rigidities in prices and wages stronger and also reproduces a more severe and persistent fall of the employment. All in all, this model generates asymmetrical real business cycles, asymmetric price and wage adjustment as well as hysteresis.

A DSGE model with loss aversion in consumption and leisure: an explanation for business cycles asymmetries

In this chapter, an asymmetric DSGE model is built in order to account for asymmetries in business cycles. One of the most important contributions of this work is the construction of a general utility function which nests loss aversion, risk aversion and habits formation by means of a smooth transition function. The main idea behind this asymmetric utility function is that under recession the agents over-smooth consumption and leisure choices in order to prevent a huge deviation of them from the reference level of the utility; while under boom, the agents simply smooth consumption and leisure, but trying to be as far as possible from the reference level of utility. The simulations of this model by means of Perturbations Method show that it is possible to reproduce asymmetrical business cycles where recession (on shock) are stronger than booms and booms are more long-lasting than recession. One additional and unexpected result is a downward stickiness displayed by real wages. As a consequence of this, there is a more persistent fall in employment in recession than in boom. Thus, the model reproduces not only asymmetrical business cycles but also real stickiness and hysteresis.

Leadership and performance in multicultural business environments a qualitative study in German-Colombian teams

Multicultural leadership is a topic a great interest in nowadays globalized work environment. Colombia emerges as an attractive marketplace with appealing business opportunities, especially for German enterprises. After presenting Colombia’s current political, social and economic situation, the thesis elaborates the complex subject of cultural differences while focusing on the peculiarities of German and Colombian national cultures. The resulting implications for a team’s collaboration and leader effectiveness are theoretically supported with reference to the landmark studies of Hofstede and GLOBE. By utilizing semi-structured interview techniques, a qualitative research enriches the previous findings and gives an all-encompassing insight in German-Colombian teamwork. The investigation identifies distinctive behavioral patterns and relations, which imply challenges and factors of success for multicultural team leaders. Finally, a categorical analysis examines the influence of cultural traits on team performance and evaluates the effectiveness of the applied leadership style.

La securitización de la migración internacional: percepción de la UE sobre el flujo de rumanos hacia el Reino Unido 2007-2014

Actualmente, el concepto de seguridad ha logrado expandirse hacia la inclusión de amenazas no tradicionales. En este contexto, el fenómeno de la migración internacional empieza a hacer parte de la agenda de algunos gobiernos, entendiéndose como un asunto que amenaza la seguridad del Estado. El interés de esta monografía gira en torno a examinar el discurso securitizador del Reino Unido sobre la inmigración rumana entre 2007-2014, con el fin de determinar la incidencia que este ha tenido en la percepción de la migración internacional como un asunto de seguridad en la UE. Al entender el discurso del Reino Unido a la luz de la teoría de securitización e incluir el análisis de la opinión pública europea, se observa que, si bien el discurso ha influido en el contexto doméstico, éste ha tenido una baja incidencia en la percepción de la migración internacional como un asunto de seguridad en la UE.
