We provide a simple model, able to explain why the overnight (ON) rate follows a downward intraday pattern, implicitly creating a positive intraday interest rate. While this normally reflects only some frictions, a liquidity crisis introduces a new component: the chance of an upward jump of the...

By analyzing high frequency data for the European interbank market, we show that the implicit intraday interest rate jumped by ten times at the outset of the 2007 financial crisis, due to an increase of the liquidity premium and of the cost of collateral.

On May 29, 2008, the Wall Street Journal reported that several large international banks were reporting unjustifiably low LIBOR rates. Since then two large banks, Barclays and UBS, have paid significant fines for manipulating their LIBOR rates, and additional banks are expected to be fined. This...

We test the effect of an important electoral reform implemented in Italy from 1993 to 2001, that moved the system for electing the Parliament from purely proportional to a plurality rule (for 75% of the seats). We do not find any effect on either the number of parties or the stability of...

We investigate the impact of news in the ECB and FED monetary policy announcements on daily changes in Euro interest rates. We document significant impacts of ECB announcements throughout the period but only until mid 2004 of FED announcements.

Central banks' operations and efficiency arguments would suggest that the intraday interest rate should be set to zero. However, a liquidity crisis introduces frictions related to news, which can cause an upward jump of the intraday rate. This paper documents that these dynamics can be partially...

Tests for cointegration with allowance for structural breaks using the extrema of residual-based tests over subsamples of the data are considered. One motivation for the approach is to formalize the practice of data snooping by practitioners, who may examine subsamples after failing to find a...
