Competition And Growth: Reconciling Theory And Evidence

Rate this book
Though competition occupies a prominent place in the history of economic thought, among economists today there is still a limited, and sometimes contradictory, understanding of its impact. In Competition and Growth, Philippe Aghion and Rachel Griffith offer the first serious attempt to provide a unified and coherent account of the effect competition policy and deregulated entry has on economic growth.The book takes the form of a dialogue between an applied theorist calling on "Schumpeterian growth" models and a microeconometrician employing new techniques to gauge competition and entry. In each chapter, theoretical models are systematically confronted with empirical data, which either invalidates the models or suggests changes in the modeling strategy. Aghion and Griffith note a fundamental divorce between theorists and empiricists who previously worked on these questions. On one hand, existing models in industrial organization or new growth economics all predict a negative effect o

An extremely lucid and fascinating exploration of the relationship between competition and growth, built out from simple models to more complex ones and explaining the interplay between these and econometric research.

Good introduction to the Aghion style inverted U shape models. Suffers from asdumption as understatement only as mich as economics generally does

Phillippe Aghion y Rachel Griffifth ofrecen un recuento de la teoría del crecimiento endógeno y sus principales predicciones relativas a la innovación y el crecimiento, que posteriormente contrastan con la evidencia empírica del efecto de la competencia en la innovación y el crecimiento.

El libro es un intento de reconciliar la teoría del crecimiento endógeno con la realidad empírica. En el proceso encuentran conclusiones sumamente importantes para la conducción de la política de competencia y la liberalización de los mercados.

Países que se encuentran próximos a la frontera tecnológica tienen ganancias importantes en términos de productividad total de los factores de incentivar una mayor competencia y políticas de liberalización, países más alejados de la frontera por el contrario tienden a ser afectados por la liberalización. Los países en desarrollo se benefician más de la acumulación de factores que de la competencia económica.

La relación entre competencia e innovación tiene la forma de una U invertida, las empresas y sectores que están más próximos a la frontera tecnológica tienen ganancias de productividad mientras que las empresas menos avanzadas pierden productividad. Los hallazgos de Aghion y Griffith parten de una revisión completa de la literatura existente con autores como Zilibotti, Blundell, Howitt y Acemoglu y de la literatura de Organización Industrial y los modelos de competencia monopolistica de Stiglitz y Dixit o el modelo de Salop.

Es un libro pequeño y muy lucido, si bien si es un libro análitico, partiendo del uso de modelos económicos el libro es accesible para un lector con experiencia previa en microeconomía y macroeconomía de nivel intermedio.
