The aim of this paper is to illustrate more than one instance of poor bootstrap performance, and to see how available diagnostic techniques can indicate reliably when and how this poor performance can arise. Two particular features that seem to be important to explain bootstrap discrepancy are...

The fast double bootstrap can improve considerably on the single bootstrap when the bootstrapped statistic is approximately independent of the bootstrap DGP. This is because, among the approximations that underlie the fast double bootstrap (FDB), is the assumption of such independence. In this...

In many, if not most, econometric applications, it is impossible to estimate consistently the elements of the white-noise process or processes that underlie the DGP. A common example is a regression model with heteroskedastic and/or autocorrelated disturbances,where the heteroskedasticity and...

We employ bootstrap methods (Efron (1979)) to test the effect of an important electoral reform implemented in Italy from 1993 to 2001, that moved the system for electing the Par-liament from purely proportional to plurality rule (for 75% of the seats). We do not find any effect on either the...

We study the impact of ECB's supervisory announcements on the Bank Stock index, from 2013 through 2017. Our evidence shows that the news, related to supervisory actions, do have highly significant effects on the market price of banks, contributing to the volatility of the Bank Stock Index for...

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...

Market efficiency hypothesis suggests a zero level for the intraday interest rate. 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 predicted during turbulent times. A...
