I use three non-linear econometric models to identify and analyze business cycles in the Peruvian economy for the period 1980:1-2008:4. The models are the Smooth Transition Autoregressive (STAR) model suggested by Ter‰svirta (1994), the extended version of the Markov-Switching model proposed by Hamilton (1989), and the plucking model of Friedman (1964, 1993). The results indicate strong rejection of the null hypothesis of linearity. The majority of models identify quarters concentrated around 1988-1989 and 1990-1991 as recession times. Other important events which happened in the Peruvian economy (natural disaster in 1983, e§ects of the Asian and Russian crises in 1990s, terrorist activities in 1980s) are not selected except as atypical observations. Most of models also identify the period 1995:1-2008:4 as a very long and stable period of moderate-high growth rates. From the perspective of the Peruvian economic history and from a statistical point of view, the MSIAH(3) model is the preferred model. Keywords: Nonlinearities, Asymmetries, STAR Model, Markov-Switching Model, Plucking Model, Recession Times JEL ClassiÖcation: C22, C52, E32. Resumen En este documento se usan tres modelos no lineales economÈtricos para identiÖcar y analizar ciclos econÛmicos en la economÌa Peruana para el perÌodo 1980:1- 2008:4. Los modelos son el modelo autoregresivo de transiciÛn suave (STAR) propuesto por Terasvirta (1994), la versiÛn extendida del modelo Markov Switching sugerido por Hamilton (1989), y el modelo Plucking de Friedman (1963, 1993). Los resultados indican fuerte rechazo de la hipÛtesis nula de linealidad. La mayorÌa de los modelos identiÖcan trimestres concentrados alrededor de 1988-1989 y 1990-1991 como recesiones. Otros eventos importantes acontecidos en la economÌa Peruana (desastres naturales en 1983, efectos de las crisis Asi·tica y Rusa en 1990, actividades terroristas en los aÒos 1980) no son seleccionadas excepto como observaciones atÌpicas. La mayorÌa de los modelos tambiÈn identiÖcan el perÌodo 1995:1-2008:4 como un periodo largo y estable de tasas de crecimiento moderadas y altas. Desde la perspectiva de la historia econÛmica Peruana y desde un punto de vista estadÌstico, el modelo MSIAH(3) es el modelo seleccionado. Palabras Claves: No Linealidades, AsimetrÌas, Modelo STAR, Modelo Markov Switching, Modelo Plucking, Recesiones ClassiÖcaciÛn JEL: C22, C52, E32.
