Until about 25 years ago, almost all European countries had a so-called “three pillar” banking system comprising private banks, (public) savings banks and (mutual) cooperative banks. Since that time, several European countries have implemented far-reaching changes in their banking systems, which have more than anything else affected the two “pillars” of the savings and cooperative banks. The article describes the most important changes in Germany, Austria, France, Italy and Spain and characterizes the former and the current roles of savings banks and cooperative banks in these countries. A particular focus is placed on the German case, which is almost unique in so far as the German savings banks and cooperative banks have maintained most of their traditional features. The article concludes with a plea for diversity of institutional forms of banks and argues that it is important to safeguard the strengths of those types of banks that do not conform to the model of a large shareholder-oriented commercial bank.
Most simulated micro-founded macro models use solely consumer-demand aggregates in order to estimate deep economy-wide preference parameters, which are useful for policy evaluation. The underlying demand-aggregation properties that this approach requires, should be easy to empirically disprove: since household-consumption choices differ for households with more members, aggregation can be rejected if appropriate data violate an affine equation regarding how much individuals benefit from within-household sharing of goods. We develop a survey method that tests the validity of this equation, without utility-estimation restrictions via models. Surprisingly, in six countries, this equation is not rejected, lending support to using consumer-demand aggregates.
