摘要:This paper analyzes the relationship between banking deregulation and product differentiation. We model banking competition by assuming both horizontal and vertical differentiation. The horizontal component is related to branching decisions whereas the vertical differentiation component is built-in to capture consumer’s satisfaction for dealing with particular bank types. We then perform an empirical analysis on the deregulation of the Spanish Banking System. We show that the direct channel from deregulation to competition successfully promoted competitive behavior among the different types of banking institutions in Spain. However,banks responded by exacerbating their differences in other dimensions,in particular in the loan market in favor of private banks. We finally estimate banks’ knowledge of demand equations and find out that private banks were more accurate than savings banks in estimating customers preferences. We hypothesize that this better knowledge has conferred private banks an advantage over savings banks for successfully differentiating private banks’ products.
