Empirical evidence of S-curves in the Colombian

The Marshall-Lerner condition, the J-curve and S-curve have emerged as theoretical and empirical foundations developed for the study of the interaction between exchange rates and international patterns of bilateral trade -- They have a significant bearing on thedevelopment of public policy, and are of equal interest to the academic and professional communities -- The most recently developed of these theories, the S-Curve, is named after the theorized short-run behavior to be found in the cross-correlation function of the real exchange rate and the trade balance -- Considering this theoretical context, the paper seeks empirical evidence of the existence of the S-Curve in the bilateral trade in commodity and non-commodity goods between Colombia and the United States and Venezuela, its main trading partners, for the yearly quarters between 1994:1 and 2009:4

Exchange rate dynamics, structural breaks, and central bank interventions in Colombia

We evaluate the effectiveness of the Colombian Central Bank´s interventions in the foreign exchange market during the period 2000 to 2014 -- We examine the stochastic process that describes the exchange rate, with a focus on the detection of structural breaks or unit roots in the data to determine whether the Central Bank´s interventions were effective -- We find that the exchange rate can be described either by a random walk or by a trend-stationary model with multiple breaks -- In neither cases do we find any evidence that the exchange rate was affected by the Central Bank interventions

Understanding import diversification: an empirical analysis

This paper analyzes import diversification in an aggregated perspective -- Using a dataset for 60 countries covering the period 1995-2010, we study the main determinants of import diversification -- We expect to contribute to the current literature, taking into account that there have been few empirical studies addressing import diversification and more specifically, at the cross-country level -- We take into account variables classified into four categories: Structural factors, macroeconomic factors, international trade factors and political factors -- We find robust evidence that total factor productivity (TFP), capital stock, real Exchange rates and terms of trade are key drivers of import diversification -- On the other hand, domestic consumption and trade openness exert an effect leading to import concentration -- We interpret this finding, taking into account the theoretical framework provided by the international trade and growth theories

Reporte financiero Burkenroad / Latinoamérica – Colombia Avianca Holdings S.A.

La recomendación de compra expuesta y el valor estimado de la acción para los próximos 12 meses se sustentan en los siguientes aspectos -- El crecimiento esperado en los próximos años en el transporte de pasajeros en la región donde principalmente opera Avianca Holdings (Latinoamérica), las inversiones de capital proyectadas por la empresa en materia de flota y eficiencia, la capacidad demostrada para mantener sostenidamente altos índices de ocupación, el posicionamiento de la marca y las estrategias concebidas al interior para reducir costos y gastos -- No obstante, a pesar de los logros obtenidos por la empresa en temas como la distribución de los ingresos y la estabilidad en los índices de ocupación, tras evaluar los resultados del análisis de sensibilidad al que se sometió la valoración realizada, debe aclararse que el alto grado de incertidumbre que caracteriza algunas de las variables determinantes de los resultados de la empresa, como el precio de los combustibles fósiles y la tasa de cambio, hacen que el valor de la acción pueda diferir de lo aquí estimado con un nivel de probabilidad considerable -- Esto hace que la recomendación de compra se adapte mejor a un perfil arriesgado de inversión
