摘要：Se estudia la relación entre gasto público, composición del gasto público y crecimiento en un modelo de crecimiento endógeno con dos bienes, comerciable y no-comerciable. El conocimiento tecnológico generado únicamente en el sector comerciable puede ser utilizado en el sector no-comerciable. Se estudia cómo un aumento del gasto público total, con una composición del gasto público que está dada, afecta a la tasa de crecimiento. Se comprueba que un aumento en el gasto público total, cuando se consume únicamente en el bien no-comerciable, produce una disminución de la tasa de crecimiento. Pero un aumento del gasto público total, con un consumo por igual en los dos bienes, no produce variación en la tasa de crecimiento.
其他摘要：A study is made of the relation between public expenditure, its composition, and growth in a model of endogenous growth, with two types of goods: tradeable and non tradeable. The technological knowledge -only generated in the traded sector- con be used in the non traded sector. How an increase in total public expenditure, whose composition is supposedly given, affects the rate of growth, is also studied. It is proved that an increase in total public expenditure, when only the non tradeable good is consumed, produces a reduction in the growth rate. But an increase in total public expenditure, in a context of equal consumption of both classes of goods, does not produce a variation in the growth rate. In fact, an increase in total public expenditure, when only the tradeable good is consumed, produces an increase in the growth rate. In this way, the composition of public expenditure in relation to these different categories is an important factor for understanding the relation between public expenditure and growth.
