This paper analyses the role of a costly financial system in the transmission of monetary policy. The new-keynesian model for a small open economy is extended with a simple financial system based on Hamann and Oviedo (2006). The presence of the financial intermediation naturally allows the…

 We use data from Bogotá and Medellín to describe key quality of life indicators of each city and illustrate their spatial segregation at the census sector level and present evidence that the main two Colombian cities are highly spatially segregated according to their education levels and…

Evidence of the causal long-term relationship between budget deficit, money growth and inflation in Colombia is analyzed in this paper, considering the standard (M1), the narrowest (M0-Base) and the broadest (M3) definitions of money supply. Using a vector error correction (VEC) model with…

The demographic transition from high to low mortality and fertility rates was one of the most important structural changes during the twentieth Century in most Latin American economies. This paper uses a simple economic framework based on Galor and Weil (2000) for understanding the main forces…

In this paper we find empirical evidence of bank lending channel for Colombia, using a balanced panel data of about four thousand non-financial firms. We find that increases in the interest rate, proxiing for the monetary policy instrument, lead to a reduction in the proportion of bank loans,…

A minimum performance insurance in the Principal-Agent problem is wealth reducing to the principal. This result points to further inefficiencies in mandatory individual Pension Funds' contracts, particularly the one established in the 1993's 100th Law in Colombia.

We use a dynamic factor model proposed by Stock and Watson [1998, 1999, 2002a,b] to forecast Colombian inflation. The model includes 92 monthly series observed over the period 1999:01-2008:06. The results show that for short-run horizons, factor model forecasts significantly outperformed the…

First developed by Markowitz (1952), the mean-variance framework is the most widespread theoretical approximation to the portfolio problem. Nevertheless, successful application in the investment community has been limited. Assumptions such as normality of returns and a static correlation matrix…

The objective of this paper is to analyze how international cycles affect the real GDP cycle and so monetary policy decisions in Colombia. We estimate that cycles in world GDP, export prices and capital inflows are strongly associated with the Colombian business cycle both on impact and even…

The assessment of inflationary pressures in Colombia has faced two important challenges in the present decade. The first one occurred in 2006 and consisted of detecting an overheating economy in the midst of fast growing investment and increasing measured productivity. The second challenge took…

 If theory-consistent models can ever hope to forecast well and to be useful for policy, they have to relate to data which though rich in information is uncertain, unbalanced and sometimes forecasts from external sources about the future path of other variables. One example from many is…

This paper presents an estimation of credit quality transition matrices for commercial banks in Colombia, using a duration hazard function model, and following the methodology proposed by Gómez-González et al (2009). Using a test developed by Weißbach et al (2005), we test for the time-…

Classic financial theory relies on the absolute perfection of capital markets, which results in one of the milestones of theoretical corporate finance: the firm’s value is invariant to the choice of capital structure. As an extension to the aforementioned proposition by Modigliani and Miller (…

This paper provides evidence of long run purchasing power parity by performing a recently developed method to test for unit roots in the presence of structural breaks. Data consist of real exchange rate series for 20 countries including developed and developing economies. Structural breaks are…

This paper studies the determinants of the probability of participating in a process of merging or acquisition for financial institutions in Colombia. We use survival analysis techniques and competing risks models to estimate the probability of participating in such processes as an acquiring or…

This document provides evidence to show that Colombia is a net exporter of 5% of its population with a university or post-graduate degree, while Argentina, Brazil and Chile are net importers of people with a similar level of education.

This paper explores the relationship between central bank independence and inflation in Latin America, using as a case study the experience of Colombia (1923-2008). Since its creation, in 1923, Colombia’s central bank has undergone several reforms that have changed its objectives and degree of…

Operational Risk (OR) results from endogenous and exogenous risk factors, as diverse and complex to assess as human resources and technology, which may not be properly measured using traditional quantitative approaches.  Engineering has faced the same challenges when designing practical…

The economic research of 30 central banks in OECD and Latin America countries from 2000 to 2007 is evaluated in this study. An international comparison based on four indexes that measure central bank research output, demand, productivity and relevance is included. From this view, the European…

The price setting behavior of Colombian retailers of goods and services was studied based on a unique dataset containing 12,052,970 individual price reports covering all items in the Colombian CPI from March 1999 to May 2008. The main results are summarized as follows: 1. Colombian consumer…
