This paper analyses the effects of sterilised, intraday foreign exchange market operations (non-discretionary and discretionary) on foreign exchange returns and volatility in four inflation targeting economies in Latin America. The distribution of exchange rates during intervention and non…

This paper uses the first wave of the Colombian Longitudinal Survey (ELCA) to analyze the relationship between individual health status and labor force participation. The empirical modeling strategy accounts for the presence of potential endogeneity between these two variables.

In this paper we set up a small open economy model with financial frictions, following Curdia and Woodford (2010)’s model. Unlike other results in the literature such as Curdia and Woodford (2010), McCulley and Ramin (2008) and Taylor (2008), we find that optimal monetary policy should not…

Typically, central banks use a variety of individual models (or a combination of models) when forecasting inflation rates. Most of these require excessive amounts of data, time, and computational power; all of which are scarce when monetary authorities meet to decide over policy interventions.…

This paper provides evidence of short-run predictability for the real exchange rate by performing out-of-sample tests of a forecasting equation which is derived from a consumption-based asset pricing model. In this model, the real exchange rate is predictable as a result of the implications of…

A small open macroeconomic model, in which an optimal interest rate rule emerges to drive the inflation behavior, is used to model inflation within an inflation targeting framework. This set up is used to estimate the relationship between commodity prices shocks and the inflation process in a…

We embed a small open economy model for Colombia into the global risk model of Gómez-Pineda, Guillaume, and Tanyeri (2014). The small open economy model is estimated by Bayesian methods and used for analysis and projections. The model enable us to give a consistent treatment of shocks to global…

This paper studies the behavior of the survival function of accruing loans during the slowdown experienced by the Colombian economy between January-2008 and March-2009 as documented by Alfonso et al. (2013). We use a dataset with information of different vintage loans between July-2007 and March…

In this paper we survey prominent theories that have shaped the literature on sterilized foreign exchange interventions. We identify three main strands of literature: 1) that which advocates the use of sterilized interventions; 2) that which deems sterilized interventions futile; and 3) that…

The world economy has recently been hit by commodity price fluctuations, with first round effects on noncore inflation and second round effects on core inflation. The policy response to commodity price fluctuations depends on the first and second round effects as well as on the strength of the…

In this paper we present estimates for the coefficients of a production function, and the corresponding total factor productivity (TFP) for the Colombian manufacturing industry during 2005{2013. We follow several structural microeconometric techniques to estimate the production function…

This paper evaluates the role of rural infrastructure on the performance of some agricultural crops in Colombia. The study utilizes geo-referenced cross sectional data of four crops, coffee, rice, beans and plantains, collected for the majority of municipalities. Using genetic matching models,…

Central banks in emerging countries frequently build-up (diminish) reserves while attempting to depreciate (appreciate) their domestic currencies. Even if these interventions are effective, they often entail various costs. Basu (2012), nonetheless, proposes a model in which the sole announcement…

This paper tests the importance of the financial structure of banks in the bank lending channel of monetary policy transmission in Colombia, using an unbalanced panel of 51 banks for the period of 1996:4-2014:8. We find that an increase in the interbank rate (proxy of the intervention rate) has…

This paper builds a general equilibrium model that incorporates banks, financial frictions, default and a capital requirements. Ex-ante heterogeneous households decide how much to save or borrow for the sake of consumption (consumer credit) or the provision of housing services(mortgages). These…

This paper studies the effects of an in utero program on birth outcomes addressed to vulnerable pregnant women. We use information from the Buen Comienzo program, an initiative run by the local government of Medellin, the second largest city of Colombia. In order to identify the effects we…

In this paper output gaps that include financial cycle information are evaluated against models used in policy analysis by the Colombian central bank. Employing this dataset is no trivial matter, since policy related models are the only relevant yardstick, and emerging economies (such as…

The balance sheet is a snapshot that portraits the financial position of a firm at a specific point of time. Under the reasonable assumption that the financial position of a firm is unique and representative, we use a basic artificial neural network pattern recognition method on Colombian banks’…

Abstract: We investigate the effectiveness of foreign exchange interventions using the Colombian experience as a case study. Recent theoretical work emphasizes the importance of financial sector balance sheets and capital flows in determining the effects of currency…

This Appendix provides a more detailed discussion of the technical results, including proofs of theorems reported in the main paper. For ease of reference notation and definitions are repeated from the main paper.
