Using a stylized model in which output is measured with error, we derive the optimal policy response to the demand shock signal and to changes in the measurement error volatility from two different perspectives: the minimization of the expected loss (from which we derive the ‘standard’ policy)…

After decades using monetary aggregates as the main instrument of monetary policy and having different varieties of crawling peg exchange rate regimes, Colombia adopted a full-fledged inflation-targeting (IT) regime in 1999, with inflation as the nominal anchor, a floating exchange rate, and the…

When managing international reserves, central banks generally face the problem of determining what their optimum or adequate level is.  A critical review of some methodologies for calculating the optimum amount of reserves is presented in this document.

We study the relationship between US and Colombian sovereign debt interest rates. We also evaluate the response of the Colombian long-term bond yield and other asset prices to shocks to the US long-term Treasury rate. Two empirical exercises are performed. First, we use a moving window linear…

In this paper, we study the empirical relationship between credit funding sources and the financial vulnerability of the Colombian banking system. We propose a statistical model to measure and predict banking-fragility episodes associated with credit funding sources classified into retail…

We assess the effects of the Colombian Unemployment Subsidy (US) program on future labor participation, unemployment, formality, school attendance and earnings of its beneficiaries, on household earnings and school attendance of the household members, and on weight and height of their children…

This study implements a regular vine copula methodology to evaluate the level of contagion among the exchange rates of six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico and Peru) from June 2005 to April 2012. We measure contagion in terms of tail dependence coefficients,…

Using data from the 2010 Colombia Demographic and Health Survey and of the National Survey of the Nutritional Situation in Colombia (ENDS-ENSIN), we analyzed the evolution of the height for the Colombian birth cohorts in the period 1946-1992 by ethnic groups defined through self-classification.…

We apply a pair-wise approach to test the law of one price for deposit (lending) rates in Colombia. We find that when banks are of different size deposit rates adjust quickly, suggesting a competitive environment. By contrast, lending rates adjust rapidly when banks are of similar size,…

In this document we use the Expectations Survey conducted monthly by the Central Bank of Colombia during the period of October 2003 – August 2012. We find that exchange rate revaluations were generally followed by expectations of further revaluation in the short run (1 month), but by…

As a result of the most recent global financial crisis literature has embraced size, connectedness and substitutability as key indicators for financial institutions’ systemic importance. Despite the intuitiveness of these concepts, identifying systemic important institutions remain a non-trivial…

Informational constraints may turn the Merton Model for corporate credit risk impractical. Applying this framework to the Colombian financial sector is limited to four stock-market-listed firms; more than a hundred banking and non-banking firms are not listed. 

This paper investigates the impact of sovereign risk on the stochastic rational expectations equilibrium of a pure exchange small open economy. International borrowing and lending arise from the interaction between a risk averse sovereign representative agent in a small open economy trying to…

In this paper I explore the potential link between Plan Colombia and violence with a new perspective. I focus the analysis only on the first three running years of the program (2000-2002) in order to avoid the overlapping effect with a security policy started in 2002/2003. This paper exploits…

This paper provides empirical evidence of the impact of fiscal decentralization on Colombia's public basic education. Based on the social and economic data available for 1,003 municipalities and 13,670 public schools, for the last decade, we confirmed that decentralization has had a positive and…

In 2013 Colombia implemented a tax reform which, among other things, reduced payroll taxes by a total of 13.5 percentage points of wages. In this paper we evaluate the effects of this component of the 2012 Colombian tax reform on firms’ formal employment and average wages. We construct a panel…

In the context of financial crises influenced by the development and burst of housing price bubbles, the detection of exuberant behaviors in the financial market and the implementation of early warning diagnosis tests are of vital importance. This paper applies the new method developed by…

We use a unique data set at the individual level to estimate an empirical model explaining the probability of young individuals to become criminals as a function of the presence of adult criminals in their neighborhoods, an a complete set of control variables, including census sector fixed…

This paper investigates whether transforming the Consumer Price Index with a class of power transformations lead to an improvement of inflation forecasting accuracy. We use one of the prototypical models to forecast short run inflation which is known as the univariate time series ARIMA . This…
