Con la adopción de la política de "Inflación Objetivo" en un buen número de países, uno de los principales objetivos de los bancos centrales se ha convertido en encontrar modelos que puedan dar una idea de la trayectoria de la inflación en el largo plazo. En este orden de ideas el presente...

Este trabajo presenta evidencia empírica sobre la no linealidad de la curva de Phillips en Colombia partiendo de la hipótesis de capacidad restringida. Así mismo, los resultados sugieren un desplazamiento de la curva hacia abajo a partir de 1999. De esta manera la economía colombiana puede...

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...

Alterar la tecnología de transacciones es un proceso endógeno motivado por el deseo de los agentes privados de reducir los requerimientos de efectivo para llevar a cabo un monto dado de transacciones en la economía. Generar este cambio en la tecnología de transacciones es costoso y un mayor...

The dynamic general equilibrium model with hiring costs presented in this paper delivers involuntary unemployment in the steady state as well as involuntary fluctuations in unemployment. The existence of hiring friction introduces externalities that, in turn, entail the breakdown of the "divine...

In an overlapping generations model, momentary equilibria are defined as points that lie on the intergenerational offer curve, i.e., they satisfy agents’ optimality conditions and market clearing at any date. However, some dynamic sequences commencing from such points may not be considered...

In this paper we develop and estimate a behavioral model of inflation dynamics with monopolistic competition, staggered price setting and heterogeneous firms. In our stylized framework there are two groups of price setters, fundamentalists and naive. Fundamentalists are forward-looking in the...

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic...

Since dollarized countries import US monetary policy, identifying US monetary shocks through sign restrictions on US variables only, does not use all available information. In this paper we therefore include dollarized countries,which enable us to restrict more variables and leave the responses...

Even though economic models have been relatively successful in explaining the long run patterns of house prices, they have more difficulties in explaining short run developments of the housing markets. However, the fact that during such ‘bubbles’ the spatial pattern of house prices, which...
