One of the principal issues of Colombian macroeconomic policy in the 1990s has been the deterioration of private savings (Figure 1). The decline in the private saving rate was usually related to consumers real expenditure, which grew by an average of 3.9% in the period 1991-1993, compared to 1.9…

This After 1991 Colombia witnessed a sharp fall in the national savings rate (see figure 1.1), and in particular that of the private sector. Two hypotheses have been advanced for explaining this behavior. The first one stresses consumption smoothing within the Perrnanent Income Hypothesis…

Graph 1 shows a conventional PPP measure of the real exchange rate in Colombia and an index of the relative price of tradable goods in terms of non tradeable. The common conclusion is that, since 1990-92 there has been a medium term process by which the RER has appreciated by as much as 26%. The…

Este documento propone un modelo multisectorial de crecimiento, dinámico y estocástico que integra la literatura de ciclo económico real con la de economías con sectores en bonanza y enfermedad holandesa para analizar fluctuaciones, asignación de recursos y los cambios en precios relativos en…

In this paper we study the structure of the fiscal system of the Viceroyalty of New Granada towards the end of the colonial period. Then we discuss how the tax system inhereted from the Spanish Empire evolved over the period 1821-1850. The conclusion that emerges from the review of the evidence…

Why justice is unresponsive to crime: Why justice is un responsive to crime: The case of cocine in Colombia

This piece was part of a research on the colombian inflationary experience published as: The Rise and Perpetuation of a Moderate Inflation, Colombia 1970-1991. It collects together the summaries of the response of Colombian policy-makers to the shocks identified in that paper. Since 1963 the…

A price-setting mechanism based on a markup over variable costs is studied for the quite different inflationary experiences of Argentina and Colombia. The paper pursues a twofold strategy: first, it test the null hypothesis of a constant markup against the alternative of a variable one; second,…

Since correlation may be interpreted as a measure of the influence across time-series, it may be conveniently mapped into a distance and into a weighted adjacency matrix. Based on such matrix, network theory has attempted to filter out the noise in correlation matrices by extracting the dominant…

The paper provides a model of the banking firm in the macroeconomy intended to explain what determines the interest rate spread. A key factor explaining the spread in our model is the resource cost of capital. A statistical result confirms the prediction of the model, that is, the bank's spread…

Structural time series models, frequency domain analysis, the HP-filter, and the Blanchard-Quah decomposition, are used to observe, some peculiarities of the business cycle. Such properties are those related to the volatility of the temporary component and the duration of the business cycle…

Exploiting spatial and temporal variations in the number of seizures from criminal organizations, I estimate regional fixed effects models of the increase in the number of properties confiscated on the main crime rates. From 2002 security strategies changed, and as a result,…

In this paper we study the effect of monetary policy shocks on commodity prices. While most of the literature has found that expansionary shocks have a positive effect on aggregate price indices, we study the effect on individual prices of a sample of four commodities. This set of commodity…

This document presents how to estimate and implement a structural VAR-X model under long run and impact identification restrictions. Estimation by bayesian and maximum likelihood methods is presented. Applications of the structural VAR-X for impulse response functions to structural shocks,…

Levels of interest rates below historical norms may have enhanced financial instability in developed and developing economies during the 2000's. The risk taking channel of monetary policy transmission is a recent theory that explains the interaction between risk perceptions of the financial…

In the past decade the Colombian Economic Authorities undertook a series of measures that reduced the structural fiscal deficit, decreased the Government currency mismatch and deepened the local fixed-rate public bond market. This paper presents some evidence suggesting that these improvements…

In this paper we show the importance of subject of degree in explaining the gender wage gap in Colombia. In order to minimize the influence of gender differences in experience, promotions, and job changes on the wage gap, we focus on college graduates who have a formal job and who have been in…

This paper propose indicator variables for the implementation of monetary policy in an inflation targeting regime. Using constant interest rate projections, the notion of a target-compatible interest rate is presented. This variable allows to extract some characteristics that the expected future…

We estimate a non-parametrical Capital Asset Pricing Model (CAPM) and find strong evidence rejecting the classical linear CAPM. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of a better and consistent…
