Deregulation and Productivity: The Case of Spanish Banks

This paper deals with measuring total factor productivity (TFP) growth of financial institutions incorporating different types of deregulatory measures. TFP growth is decomposed into external, scale, and markup (in output prices) components. The contribution of the external component is further dissected into several types of deregulation and technical change components. We include the TFP growth relationship as an additional equation in estimating the cost system. The empirical model uses panel data on Spanish banks (savings and commercial), primarily because the Spanish banking sector went through rapid deregulatory changes. We find that deregulations, in general, contributed positively to TFP growth for both savings and commercial banks. Furthermore, domestic (European) deregulations had a greater effect on TFP growth of savings (commercial) banks.
