The history of economic recessions has shown that every deep downturn has been accompanied by disruptions in the …financial sector. Paradoxically, up until the …financial world crisis of 2007-2009, little attention was given to macroeconomic and …financial interdependence. And, in spite of a…

A regular vine copula approach is implemented for testing for contagion among the exchange rates of the six largest Latin American countries. Using daily data from June 2005 through April 2012, we find evidence of contagion among the Brazilian, Chilean, Colombian and Mexican exchange rates.…

This paper examines the non-reversal of fortune thesis proposed by Acemoglu, Johnson, and Robinson (2002) in the light of the Colombian experience over the last 500 years. Using a total of 14 national population censuses and the record of tributary Indians in 1559, it is found that the…

We study the network of Colombian sovereign securities settlements. With data from the settlement market infrastructure we study financial institutions’ transactions from three different trading and registering individual networks that we combine into a multi-layer network.

We study …nancial crises in a small open production economy subject to credit constraint and uncertainty on the value of debt repayments. We …nd that the possibility of reducing the severity of future crises encourages the central planner (CP) to increase both the crisis frequency and current…

During the 1920s, the Colombian economy experienced the highest rate of growth in its history. The economic reforms of 1923 (the central bank, gold standard, banking legislation, fiscal reorganization), the coffee boom, and the unprecedented influx of foreign capital were the driving forces…

In this paper we expanded the closed economy model by Bernanke and Gertler (1999) in order to account for the macroeconomic effects of an asset price bubble in the context of a small open economy model. During the nineties emerging market economies opened their financial accounts to foreign…

Many central banks, particularly in the developing world, aim for exchange rate stability as a macroeconomic goal. However, most are reluctant to relinquish monetary policy autonomy, so they end up operating through both interest rate and foreign exchange interventions. But the use of multiple…

This paper analyzes the effect of social security and lump sum layoff payment in an economy with an informal sector and savings, where the search effort is unobserved. I characterize the optimal consumption/search/non-participant strategy assuming that workers are risk averse and that formal…

This paper analyzes efficiency in an economy with an informal sector that consists of unregulated self-employment, and where there are no costs of being informal, (Albrecht et al. (2009)). First, assuming workers in the formal sector are ex-ante heterogeneous, I show that this type of economy is…

This paper contributes to the theoretical analysis of the informal sector in the search and matching framework. Building upon the work of Albrecht et al. (2009), where the informal sector consists of unregulated self-employment, I describe the search and matching equilibrium in an economy with…

This paper evaluates the impact of Resolution CREG 051 on the performance of the electricity markets in Colombia. We found out that productive efficiency has improved since the introduction of the Resolution, that is, the total costs of producing electricity have been reduced. This shows a…

R&D intensity for small firms is high and persistent over time. At the same time, small firms are often financially constrained. This paper proposes a theoretical model that explains the coexistence of these two stylized facts. It is shown that self-financed R&D investment can distort…

This paper presents evidence of the effect of the recent phases of the business cycle in Spain and United States, proxied by their respective unemployment rates, on the labor market of Colombian cities with high migration tradition. These countries are the main destination for labor Colombian…

The most recent global financial crisis (2008-2009) highlighted the importance of systemic risk and promoted academic interest to develop a wide set of warning indicators, which are mechanisms to identify systemically important institutions and global systemic risk indexes. Using the methodology…

We propose to assess the performance of k forecast procedures by exploring the distributions of forecast errors and error losses. We argue that non systematic forecast errors minimize when their distributions are symmetric and unimodal, and that forecast accuracy should be assessed through…

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 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…

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.

In the present paper we remark that the absence of an intrinsic or fundamental value represents a problem for the stability of the bitcoin’s price as an asset. In addition, we consider some financial stability concerns that derive from the hypothesis that the bitcoin will survive as an asset…
