I provide a framework for understanding debt deleveraging in a group of financially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reflecting a high propensity to save. If exchange rates are allowed...

We estimate the response of stock prices to exogenous monetary policy shocks using a vector-autoregressive model with time-varying parameters. Our evidence points to protracted episodes in which, after a a short-run decline, stock prices increase persistently in response to an exogenous...

This paper reexamines the classical issue of the possible trade-offs between banking competition and financial stability by highlighting different types of risk and the role of leverage. By means of a simple model we show that competition can affect portfolio risk, insolvency risk, liquidity...

This paper adds some new arguments to the thesis that the responsibility for banking supervision should be assigned to an agency formally separated by the Central bank. We also provide some additional evidence on the macro and microeconomic performance of OECD countries whose banking systems are...

Since its inception, a most distinctive (and controversial) feature of the ECB monetary policy strategy has been its emphasis on money and monetary analysis, which constitute the basis of the so-called monetary pillar. The present paper examines the performance of the monetary pillar around the...

We survey the theory of banking regulation from the general perspective of regulatory theory. Starting by considering the different justifications of financial intermediation, we proceed to identify the market failures that make banking regulation necessary. We then succinctly compare how the...

This paper demonstrates that all rank test statistics are functions of implicit null space estimators. The paper proposes a novel theory of null space estimation that allows for standard asymptotics, polynomial regressions, and cointegration asymptotics. The paper proves that the behaviour of...

We propose a residual-based augmented Dickey-Fuller (ADF) test statistic that allows for detection of stationary cointegration within a system that may contain both I (2) and I (1) observables. The test is also consistent under the alternative of multicointegration, where first differences of...

This paper discusses the role of deterministic components in the DGP and in the auxiliary regression model which underlies the implementation of the Fractional Dickey-Fuller (FDF) test for I(1) against I(d) processes with d € [0, 1). This is an important test in many economic applications...

We present a new method for constructing exact distribution-free tests (and confidence intervals) for variables that can generate more than two possible outcomes. This method separates the search for an exact test from the goal to create a non- randomized test. Randomization is used to extend...
