An endogenous growth model with a financial sector is formulated, and empirical analyses are conducted. The model exhibits structural shifts and breaks caused by institutional change, suggesting that a linear approach is inadequate. To address this point empirically, we fit data for 90 countries from 1960-2000 to a standard growth equation with a proxy for financial activity. Firstly, it is shown that a growth enhancing outcome of financial activity is contingent on a sound institutional framework. Then, we order the sample by control variables which follow from the model as potential causes of breaks in the adjustment process. Threshold regressions reveal non-linearity that is consistent with the model. Most importantly, we find signs for excessive financial activity.
