Working Papers on Economics

  This paper contains a nonlinear, nonstationary autoregressive model whose intercept changes deterministically over time. The intercept is a flexible function of time, and its construction bears some resemblance to neural network models. A modeling technique, modified from one for single…

We assess whether international remittances affect Colombian household’s expenditure composition and demand of education. We exploit the migratory wave that took place on late 90s due to one of the deepest crises in Colombian history, along with institutional barriers to migration, to identify…

This paper presents a multimarket spatial competition oligopoly model for the Colombian deposit market, in line with the New Empirical Industrial Organization (NEIO) approach. In this framework, banks use price and non-price strategies to compete in the market, which allows us to analyze the…

This paper identifies the main bank specific determinants of time to failure during the financial crisis in Colombia using duration analysis. Using partial likelihood estimation, it shows that the process of failure of financial institutions during that period was not a merely random process;…

Banks and other credit institutions are key players in the transmission of monetary policy, especially in emerging market economies, where the responses of deposit and loan interest rates to shifts in policy rates are among the most important channels. This pass-through depends on the conditions…

During the transition from a moderately high level of inflation to an internationally accepted level, the target, the inflation rate, the nominal interest rate and the nominal equilibrium interest rate may be difference stationary. Policy rules estimation, however, is usually performed under…

In this paper we explore the price setting behavior of Colombian producers and importers using a unique database containing the monthly price reports underlying the Colombian PPI from Jun-1999 to Oct-2006. We focus on five particular questions:

The main purpose of this chapter is to summarize the information currently available on cocaine production and trafficking. The chapter starts by describing the available data on cocaine production and trade, the collection methodologies, (if available) used by different sources, the main biases…

Financial system’s health is a signal of economic growth therefore it is a key indicator to investors. As a consequence, one of the main purposes of policymakers is to keep its stability as well as protect it from foreign activity. Both financial and economic activity in general are susceptible…

This paper approaches active management of baskets of currencies from the perspective of Complexity theory, where the market is analysed as a Complex Adaptive system. A basket of currencies is constructed using objective probabilities (propensities) and an artificial intelligence optimization…

This paper examines whether central banks in Latin America have implemented conventional inflation targeting (IT) prescriptions, with a focus on foreign exchange intervention and official reserves accumulation policies. To this end, the paper reviews the experiences of Brazil, Chile, Colombia,…

Colombia experienced a deep recession in 1999-2003. Growth slowed by 4.2%, and investment by 34.6%. Was the severity of the recession due to a financial accelerator mechanism á la Bernanke, Gertler, and Gilchrist (1999)? To answer this question, this paper estimates a dynamic stochastic general…

There is now an impetus to apply dynamic stochastic general equilibrium models to forecasting. But these models typically rely on purpose-built data, for example on tradable and nontradable sector outputs. How then do we know that the model will forecast well, in advance? We develop an early…

This study presents an alternative way of estimating credit transition matrices using a hazard function model. The model is useful both for testing the validity of the Markovian assumption, frequently made in credit rating applications, and also for estimating transition matrices conditioning on…

This paper extends the asymptotic results of the dynamic ordinary least squares (DOLS) cointegration vector estimator of Mark and Sul (2003) to a three-dimensional panel. We use a balanced panel of N and M lengths observed over T time periods. The cointegration vector is homogenous across…

his paper surveys some facts relevant for the understanding of the Colombian experience with public finance and debt since 1923. The stylized facts are classified in three groups as follows: first, facts associated with the dependence of the economy on the external sector; second, facts which…
