This paper investigates the role of domestic and external factors in explaining business cycle and international trade developments in fifteen emerging market economies. Results from sign-restricted VARs show that developments in real output, inflation and international trade variables are…

Can frictionless small open economy models driven solely by technology shocks account for business cycles in developing countries? We do not find evidence of it. We build a DSGE model that jointly includes a variety of real perturbations in addition to technology shocks, such as procyclical…

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…

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…

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…

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…

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…

In this paper, we propose a methodology for calculating a leading index of the economic activity based on a modification of Stock and Watson’s (1989, 1991, 1992) approach. We use Kalman filter techniques for estimating the state space representation of the leading index model. The methodology is…

In this paper, we modeled the Colombian long run economic growth (1925-2003) using a two- regime first order Markov switching model. We found evidence of non-linearity in the annual rate of economic growth. The results show that changes between regimes are sudden and sporadic. The Colombian…

Since 1991, inflation in Colombia was reduced from 25% on average to about 6% more recently. Although this performance is in line with a long run inflation target of 3%, some analysts ask whether the Central Bank should continue disinflating. In this paper we present a dynamic stochastic general…

Colombia experienced a deep recession in 1999-2003. Growth slowed by 4.2%, and investment by 34.6%. Was the severity of the recession due to a financial accelerator mechanism á la Bernanke, Gertler, and Gilchrist (1999)? To answer this question, this paper estimates a dynamic stochastic general…

The purpose of this study is twofold: First, it provides an empirical characterization of fiscal policy in Colombia over the last decades, by assessing the three most relevant macroeconomic factors: the behavior of fiscal policy over the business cycle; whether it has been coherent with the long…

This article analyzes identification problems that may arise while linearizing and solving DSGE models. A criterion is proposed to determine whether or not a set of parameters is partially identifiable, in the sense of Canova and Sala (2009), based on the computation of a basis for the null…
