Resumen
Este artículo estudia la validez y estabilidad temporal de la Ley de Okun para 10 países de América Latina durante el periodo 1980-2023, en consideración a los efectos de la política fiscal. Para el caso, se estima un modelo TVP-VAR-SV para capturar relaciones dinámicas entre el crecimiento del producto interno bruto (PIB) y la variación de la tasa de desempleo y del gasto de consumo final del Gobierno como proporción del PIB, en atención a cambios estructurales y escenarios de incertidumbre. Los resultados del primero de los dos ejercicios econométricos muestran que esta relación no ha sido estable, ni homogénea, entre los países de la muestra a lo largo del tiempo. Del segundo ejercicio, se concluye que la inclusión de una tercera variable produce efectos diferenciados sobre la relación tradicional planteada por la Ley de Okun y sobre la variación del desempleo.
