Infrainversión versus Sobreinversión

Author

Abstract

En este trabajo se utiliza un modelo, que relaciona el valor de las acciones de la empresa y el nivel de inversión, para una vez estimado, con la metodología de datos de panel, contrastar las hipótesis de infrainversión y sobreinversión. Los resultados obtenidos indican que la relación entre valor de las acciones de la empresa e inversión es cuadrática, lo que implica que existe un nivel óptimo de inversión. En consecuencia, las empresas que se sitúan en un nivel inferior al óptimo sufren un problema de infrainversión, mientras que las empresas que se sitúan en un nivel superior al óptimo sufren el problema de sobreinversión. La relación cuadrática anterior se mantiene cuando se clasifican las empresas de acuerdo con sus oportunidades de inversión. Además, de acuerdo con la teoría, aquellas empresas que a lo largo del período de análisis tienen una q de Tobin mayor que 1 poseen un nivel óptimo de inversión superior a las que su q es inferior a 1. We study the relationship between firm value and investment to test the underinvestment and overinvestment hypotheses. The results obtained, using panel data methodology as the estimation method, indicate that the abovementioned relation is quadratic, which implies that there exists an optimal level of investment. As a consequence, firms that invest less than the optimal level suffer from an underinvestment problem, while those investing more than the optimum suffer from overinvestment. The quadratic relation is maintained when firms are classified depending on their investment opportunities, the optimum being in accordance with the quality of investment opportunities.
