Following an intuition often attributed to Hicks (1932), I ask whether and how population aging aff ects the relative scarcity of factors of production, relative factor prices, and the direction of induced technical change. Aging is equivalent to an increase in the old-age dependency ratio of an OLG-economy with two-period lived individuals. In this framework aging increases the relative scarcity of labor with respect to capital. Therefore, there will be more labor- and less capital-saving technical change. Unless there are contemporaneous knowledge spillovers across innovating firms technical change induced by a small increase in the old-age dependency ratio has no first-order effect on current GDP. The presence of capital-saving technical change is shown to imply that the economy's steady-state growth rate is independent of its age structure. abstract_translated_lang: eng class_scheme: jel class_labels: O41, O33, D92, D91 date: 2009 date_type: published id_scheme: DOI id_number: 10.11588/heidok.00010172 schriftenreihe_cluster_id: sr-3 schriftenreihe_order: 0493 ppn_swb: 1649866666 own_urn: urn:nbn:de:bsz:16-opus-101722 language: eng bibsort: IRMENANDREPOPULATION2009 full_text_status: public citation: Irmen, Andreas (2009) Population Aging and the Direction of Technical Change.
