Scale-free (inhomogeneous) connective structures with modular (highly clustered) hierarchies are ubiquitous in real–world networks. Evidence from the main Colombian payment and settlement systems verifies that local financial networks have self-organized into a modular scale-free architecture...

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...

To evaluate whether transparency is beneficial, it is usual to assume that the central bank may choose one of two options, opacity versus truthful communication. However, the monetary policymaker may have incentives to misrepresent private information so as to reduce economic volatility by...

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...

En este trabajo se evalúa la calidad del empleo en Colombia. Usualmente, la calidad del empleo ha sido analizada a través de indicadores sintéticos que resumen sus distintas dimensiones. Sin embargo, esta aproximación carece de un marco teórico que respalde la elección y la ponderación de...

La reciente crisis financiera internacional volvió a dar relevancia a la formación de ciertos desbalances macroeconómicos que pueden aumentar las vulnerabilidades de una economía frente a choques adversos. En el caso de las economías emergentes, flujos elevados de capital podrían exacerbar...

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...

Despite various payment innovations, today, cash is still heavily used to pay for low-value purchases. This paper develops a simulation model to test whether standard implications of the theory on cash management and payment choices can explain the use of payment instruments by transaction size....

The adoption of a managed regime assumes that interventions are relatively successful. However, while some authors consider that foreign exchange interventions are ineffective, arguing that domestic and foreign assets are close substitutes, others advocate their use and maintain that their...

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...
