The study of the asymmetric behavior of macroeconomic variables over the business cycles phases has had a long tradition in economics. In this work we find evidence in favor of the hypothesis of having a STAR-type nonlinear asymmetric behavior of the economic activity, over the last two decades…

I build a general equilibrium, financial accelerator model that incorporates an explicit technology for the intermediary sector. A credit multiplier emerges because of a borrowing constraint that is a function of asset prices, internal funds and lending rates. With this financial friction I show…

The construction of coincident indexes for the economic activity of a country is a common practice since the fifties. The methodologies vary from heuristic methods to probabilistic or statistical ones. In this paper, we present a new procedure for estimating a coincident index of the state of…

A Statement of the Colombian Constitutional Court has mandated wage indexation on the basis of past inflation. A simple model with a wage price system, a real block, and an inflation targeting interest rule is calibrated to resemble price setting in the Colombian economy and to analyze the…

There is large body of empirical literature devoted to study the relationship between inflation and long-run growth. Recently, levine and Renelt (1992) encouraged by new developments in growth theory investigated, within a unified framework, the effet of a number of variables on per capita…

This paper presents a novel monthly dataset of job vacancies in Bogota between 1960 and 2010. The dataset was constructed by counting the number of help-wanted announcements published in the most important newspaper with national circulation—namely, El Tiempo. We describe the methodology used to…

The purpose of this paper is to analyze the links between central bank independence and foreing exchange policies, in the light of the recent experience of the major Latin American countries. To that end, the paper starts with a brief review of the literature on the subject. The second section…

A basic theoretical of a small open economy within the framework of intertemporal maximization is used to analyze the effects of nominal export shocks. The model helps in explaining the close relationship that is found between export shocks and short run fluctuations of domestic savings in the…

Colombian inflationary experience is explained using a theoretical model that stresses two elements: the effect of shocks and the type of policy designed to respond to them. The empirical investigation uses the event-study methodology and finds that the model successfully accounts for the main…

The analysis of the impacts of coffee bonanzas and crisis on the Colombian economy, given its importance, has been one of the favorite topics of research both by Colombian and foreing economists, Cárdenas (1991); Carkovic (1992); Cuddington (1986); Ocampo (1994); Posada (1992); Urrutia and…

Imagine a country whose inflation rate has recently surpassed 300% a year, and during some months even surpassed the 50% level that was estabilished as a benchmark for the definition of Phillip Cagan's classic study on the subject. This rapid inflation led to a devaluation of the local currency…

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…

Single-sex classes within coeducational environments are likely to modify students' risktaking attitudes in economically important ways. To test this, we designed a controlled experiment using first year college students who made choices over real-stakes lotteries at two distinct dates. Students…

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 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…

We study the  existence of a monetary policy transmission mechanism through banks in Colombia, using monthly banks’ balance sheet data for the period 1996:4 – 2012:12. We obtain results which are consistent with the basic postulates of the bank lending channel (and the risk-taking channel)…
