In order to assess the importance of monetary and financial developments for key macroeconomic variables in the euro area a money demand system for M3 is estimated adopting a structural cointegrating VAR approach. While maintaining a good statistical representation of the data, long-run relationships are based on economic theory. By using generalized response profiles the dynamics of the money demand system is investigated without any further identifying assumptions. Error bounds of the profiles are derived using bootstrap simulations.

In this paper we study European banks' demand for short-term funds (liquidity) during the summer 2007 subprime market crisis. We use bidding data from the European Central Bank's auctions for one-week loans, their main channel of monetary policy implementation. Through a model of bidding, we show that banks' behavior reflects their cost of obtaining short-term funds elsewhere (i.e., in the interbank market) as well as a strategic response to other bidders. We find considerable heterogeneity across banks in their willingness to pay for short-term funds supplied in these auctions. Accounting for the strategic component is important: while a naive interpretation of the raw bidding data may suggest that virtually all banks suffered a dramatic increase in the cost of obtaining funds in the interbank market, we find that for about one third of the banks, the change in bidding behavior was simply a strategic response. Using a complementary data set, we also find that banks' pre-turmoil liquidity costs, as estimated by our model, are predictive of their post-turmoil liquidity costs, and that there is considerable heterogeneity in these costs with respect to the country-of-origin. Finally, among the publicly traded banks, the willingness to pay for short-term funds in the second half of 2007 are predictive of stock prices in late 2008.
