This study examines the martingale difference hypothesis (MDH) for the market of carbon emission allowances within the European Union Emission Trading Scheme (EU ETS) during the Phase I and the Phase II, using both daily and weekly data over the period 2005--2009. The weak-form efficient market...

In this paper, we study the relationship between futures and spot prices in the European carbon markets from the cost-of-carry hypothesis. The aim is to investigate the extent of efficiency market. The three main European markets (BlueNext, EEX and ECX) are analyzed during Phase II, covering the...

In this paper, we attempt to examine the speculative efficiency hypothesis on CO2 emission allowance prices negotiated on Bluenext, by testing the relationship between futures and spot prices from the Fama (1970) framework. This approach is based on the joint hypothesis of no risk premium and...

In this paper we investigate the effect of the outliers on the decomposition of Nelson-Plosser macroeconomic data set into permanent and transitory components from structural time series models. We show that the outliers can disturb the unobserved-components decomposition, especially the...

This article extends earlier efforts at redating the US industrial cycles for the prewar period (1890–1938) using the methodologies proposed by Bry and Boschan (1971) and Hamilton (1989) and based on the monthly industrial production index constructed by Miron and Romer (1990). The alternative...

A Monte Carlo experiment is conducted to compare power properties of alternative tests for the martingale difference hypothesis. Overall, we find that the wild bootstrap automatic variance ratio test shows the highest power against linear dependence; while the generalized spectral test performs...
