Perdurabilidad empresarial. Los hechos del sector servicios

El sector servicios, identificado como el de mayor dinámica competitiva en los mercados globalizados, en las actuales condiciones basa su acción en el conocimiento de su entorno en tanto que sus productos, en general, tienden a ser personalizados, o por lo menos, suponen una gama amplia de escogencia para los consumidores. En este sentido y dados los altos niveles de competencia, se precisa formular una estrategia evolutiva eficiente, a partirdel reconocimiento de la información del entorno. Estos hechos estilizados pretenden mostrar datos del entorno y algunas regularidades, las cuales serán modeladas en el resultado definitivo presentado en el artículo final de este trabajo de investigación.

Labor's shares - aggregate and industry: accounting for both in a model of unbalanced growth with induced innovation

The relative stability of aggregate labor's share constitutes one of the great macroeconomic ratios. However, relative stability at the aggregate level masks the unbalanced nature of industry labor's shares – the Kuznets stylized facts underlie those of Kaldor. We present a two-sector – one labor-only and the other using both capital and labor – model of unbalanced economic development with induced innovation that can rationalize these phenomena as well as several other empirical regularities of actual economies. Specifically, the model features (i) one sector ("goods" production) becoming increasingly capital-intensive over time; (ii) an increasing relative price and share in total output of the labor-only sector ("services"); and (iii) diverging sectoral labor's shares despite (iii) an aggregate labor's share that converges from above to a value between 0 and unity. Furthermore, the model (iv) supports either a neoclassical steadystate or long-run endogenous growth, giving it the potential to account for a wide range of real world development experiences.
