RXTE confirmation of the intermediate polar status of IGR J15094-6649
Aims. To establish the X-ray properties of the intermediate polar candidate
IGR J15094-6649 and therefore confirm its inclusion into the class.
Methods. 42 856 s of X-ray data from RXTE was analysed. Frequency analysis
was used to constrain temporal variations and spectral analysis used to
characterise the emission and absorption properties.
Results. A spin period of 809.7+-0.6 s is present, revealed as a complex
pulse profile whose modulation depth decreases with increasing X-ray energy.
The spectrum is well fitted by either a 19+-4 keV Bremsstrahlung or
Gamma=1.8+-0.1 power law, with an iron emission line feature and significant
absorption in each case.
Conclusions. IGR J15094-6649 is confirmed to be an intermediate polar.Comment: 3 pages, 5 figures. Submitted to A&
Gathering insights on the forest from the trees: a new metric for financial conditions
By incorporating the Harvey accumulator into the large approximate dynamic factor framework of Doz et al. (2006), we are able to construct a coincident index of financial conditions from a large unbalanced panel of mixed frequency financial indicators. We relate our financial conditions index, or FCI, to the concept of a "financial crisis" using Markov-switching techniques. After demonstrating the ability of the index to capture "crisis" periods in U.S. financial history, we present several policy-geared threshold rules for the FCI using Receiver Operator Characteristics (ROC) curve analysis.Financial crises ; Financial markets
Chicago Fed National Activity Index turns ten - analyzing its first decade of performance
This article discusses how the Chicago Fed National Activity Index has performed as a “real-time” indicator of economic activity and related inflationary pressure.
Monitoring financial stability: a financial conditions index approach
Monitoring financial stability requires an understanding of both how traditional and evolving financial markets relate to each other and how they relate to economic conditions. This article describes two new indexes of financial conditions that aim to quantify these relationships.Financial stability ; Financial crises ; Finance
What is the relationship between large deficits and inflation in industrialized countries?
Examining industrialized countries, the authors find that large deficits are not associated with higher inflation contemporaneously, nor are they associated with the emergence of higher inflation in subsequent years. This finding suggests that countries that can afford large deficits have built solid reputations and institutions supporting a sound monetary policy and the reversion to a stable fiscal regime.
