This paper deals with the modelling of the global and northern and southern hemispheric anomaly temperature time series using a novel technique based on segmented trends and fractional integration. We use a procedure that permits us to estimate linear time trends and orders of integration at...

This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

This paper examines the robustness of fractional integration estimates to different data frequencies. We show by means of Monte Carlo experiments that if the number of differences is an integer value (e.g., 0 or 1) there is no distortion when data are collected at wider intervals; however, if it...

In this paper we study the suitability of the CAPM to the Spanish Stock Market Interconnection System (SIBE) for the period 1988-2000, by means of time series and cross-section multivariate tests. Even though there is no enough empirical evidence to reject this model, it is shown that the...

This paper employs various empirical tests in order to measure the persistence of shocks to EPS for the S&P 500 index. Within the I(0)/I(1) paradigm the empirical evidence rejects the I(1) specification, supporting instead a trend-stationary representation. When fractional orders of integration...

The aim of this paper is to analyse the empirical fulfilment of the Purchasing Power Parity (PPP) theory for the Australian dollar. In order to do so we have applied recently developed unit root tests that account for asymmetric adjustment towards the equilibrium (Kapetanios et al., 2003) and...

This paper analyses the effectiveness of anti-terrorism policies implemented by the Spanish government to counteract ETA terrorist attacks. The aim is to investigate what the best policy is for counteracting terrorist groups: proactive political/retaliatory deterrence policies or reactive...

This paper analyzes whether the excessive overreliance on non-interest income and wholesale funding, which occurred in the banking industry during the last two decades and led to increases in systemic risk, could arise from the desire of bank managers to increase their variable compensation....

Empirical evidence has so far failed to confirm that lenient environmental regulation attracts investment from polluting firms. We show that a firm may want to relocate to a country with stricter environmental regulation, when the move raises its rival's cost by sufficiently more than its own....

Fair value accounting in banking has been criticized for the increased volatility that it generates in some accounting variables. One of its advantages, however, is that it reduces the possibility of discretionary earnings management, given that all gains and losses are immediately recognized....
