Comportamiento cíclico en las importaciones y exportaciones cubanas: un análisis desde el dominio de las frecuencias.
El propósito de este trabajo es estudiar las periodicidades o ciclos detectables en las series de las importaciones y exportaciones cubanas, haciendo uso del análisis espectral. En las últimas dos décadas, la economía cubana ha experimentado cambios como la inserción del sector privado y la inversión extranjera. Por lo tanto, es de interés conocer el comportamiento recurrente de la actividad económica en el corto plazo. La idea de identificar ciclos detectables en lugar de realizar un estudio completo de los ciclos económicos de la actividad se fundamenta en que las series disponibles no son muy extensas y un análisis de periodicidades de largo período requiere muestras estadísticas grandes. El objetivo planteado aquí es mucho más modesto. Se requiere identificar movimientos particularmente en períodos cortos y obtener información precisa sobre tales periodicidades.
