Presentem un model de compensació d'estructura de capital per investigar les fonts dels costos d'ajustament i estudiem com les decisions de finançament de les empreses determinen un ajust parcial a les ràtios d'apalancament objectiu. La presència d'imperfeccions del mercat, com ara impostos i restriccions de garantia, demostra un paper decisiu en el comportament de la funció política del capital i l'apalancament. Mitjançant un argument de contracció, podem demostrar l'existència d'un apalancament objectiu cap al qual convergeix un palanquejament òptim amb una velocitat d'ajustament que depèn d'una productivitat marginal ferma del capital. Les nostres prediccions són coherents amb la literatura empírica quant a la magnitud de la velocitat d'ajust i la relació entre els coeficients d'apalancament i el cicle econòmic.
We present a tradeoff model of capital structure to investigate the sources of adjustment costs and study how firms' financing decisions determine partial adjustment toward target leverage ratios. The presence of market imperfections, like taxes and collateral constraints, is shown to play a decisive role in the behavior of the policy function of capital and leverage. By means of a contraction argument, we are able to show the existence of a target leverage towards which optimal leverage converges with a speed of adjustment that depends on a firm marginal productivity of capital. Our predictions are consistent with the empirical literature regarding both the magnitude of the speed of adjustment and the relationship between leverage ratios and the business cycle.
