    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 paper examines trends in banknote printing during the period 2000-2005 for a crosssection of 56 central banks. It was identified that central banks have implemented new strategies to increase efficiency in the production of banknotes, primarily due to the increase in the demand for currency…

    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…

    Our current implementation of the Fan Chart follows the original Britton Fisher and Whitley [2] and Blix and Sellin [1] proposal in which the inputs enter at the fourth and ninth quarters and are distributed within the forecasting horizon according to pre established weights. This procedure does…

    In order to asses the credibility of their targets and policies, inflation targeting central banks always keep an eye on market expectations of the future inflation rates and short maturity interest rates. In economies with developed financial markets the prices of financial assets are a prime…

    Asset prices have recently become a common topic in economic debate. Nevertheless, much time has been spent in determining if they effectively exhibit a bubble component, and not in examining whether asset prices affectively contain relevant information concerning future market developments.…

    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…

    Using Bayesian estimation techniques, we estimate a small open economy DSGE model with credit-market imperfections for the Colombian economy. Using the estimated model we investigate what are the sources of business cycle fluctuations. We show that balance-sheet effects play an important role in…

    This paper presents two versions of a spatial competition model for the banking sector. The first version, describes a framework that follows closely Salop´s spatial competition model. This version is modified in the second part by introducing the loan market and default risk probabilities for…

    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…

    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…

    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.

    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 (…

    In financial theory, the optimal allocation of assets and its relationship with profitability has been one of the main concerns; the question has always been if banks should focus or diversify their assets. In our case, we would like to answer this question focusing in diversification of the…

     We examine Colombian export transaction data from customs records in several dimensions. We begin with some basic statistics on the number and frequency of export transactions by a firm, overall and across individual markets. We then decompose the variation in overall exports into the…
