There have been substantial increases in liquidity in recent years and real oil prices have almost returned to the high levels achieved before the global financial crisis. Unanticipated increases in global real M2 led to statistically significant increases in real oil prices. The historical...

Monetary policy may constitute a short-term explanation of the non-linearity in the relationship between oil prices and output. The role of oil prices in the ECB reaction is thus investigated with an extended Taylor rule including several oil prices indicators.

The article investigates causality between fossil fuel prices, exchange rates and the German Stock Index (DAX). The analysis is conducted dynamically with the use of rolling VAR methodology on the basis of weekly data from the period October 2001–June 2012. The results obtained show that the...

This paper applies a pairwise approach to investigate the validity of the law of one price in the crude oil markets. Price differentials appear smaller between crude oil pairs with similar physical/chemical characteristics and also for pairs within OPEC.

Castagnetti et al. (2015) propose two max-type statistics to test for the presence of a factor structure in a large stationary panel data model. In this contribution, we study the use of Hausman-type statistics based on the CCE estimator of Pesaran (2006) and the IE estimator developed by Bai...

In this paper we show that rent-sharing plays a role in explaining the glass ceiling effect. We make use of a unique employer–employee panel database for Italy from 1996 to 2003, which allows controlling for observed individual and firm heterogeneity and for collective bargaining. Moreover, by...

In this paper, we test the Prebish–Singer (PS) hypothesis, which states that real commodity prices decline in the long run, using two recent powerful panel data stationarity tests accounting for cross-sectional dependence and a structural break. We find that the hypothesis cannot be rejected...

Applications of panel unit root tests have become commonplace in empirical economics, yet there are ambiguities as how best to interpret the test results. This note clarifies that rejection of the panel unit root hypothesis should be interpreted as evidence that a statistically significant...

A simple data-dependent filtering method is proposed before applying the Bai–Ng method to estimate the number of common factors in the conventional approximate factor model. The asymptotic justification is provided and the finite-sample performance is examined.

This note explores clustering in cross country GDP per capita using recently developed model based clustering methods for panel data. Previous research characterizing the components of the overall distribution of output either use ad hoc methods, or methods which ignore/subvert the panel nature...
