Service-oriented models for audiovisual content storage
No full textWhat are the important topics to understand if involved with storage services to hold digital audiovisual content? This report takes a look at how content is created and moves into and out of storage; the storage service value networks and architectures found now and expected in the future; what sort of data transfer is expected to and from an audiovisual archive; what transfer protocols to use; and a summary of security and interface issues
C. S. Phillips letter, W.0143
No full textAbstract: Letter detailing the movement of Union forces following the surrender of Mobile, Alabama, in April 1865.Scope and Content Note: C. S. Phillips of the Ninety-fourth Illinois Volunteer Infantry Regiment wrote this letter on April 18, 1865, from Spanish Fort, Alabama, to his friend Will H. Hay. Phillips details the movements of his company toward and around Mobile, Alabama, and ends saying, "We live in hopes. We are looking for good news from Genl Shermans Army! since the surrender of Gen; Lee. How glorious."Biographical/Historical Note: C. S. Phillips was a Union soldier in Company I of the Ninety-fourth Illinois Volunteer Infantry Regiment, First Brigade, Second Division, during the last stages of the Civil War

Is the Phillips Curve of Germany Spurious?
No full textA simple plot of seasonal adjusted quarterly data between the change of nominal wage rates and the unemployment rate for the German economy shows a picture similar to that by which Phillips was inspired to his famous discovery, that there is a long-term tendency of a negative, non-linear relationship coupled with minor deviations from this tendency, which form so-called loops. At first sight, the Phillips Curve of Germany comprises clusters of data points and movements between these clusters. In spite of the striking differences of these phenomena, a model with one regression equation is sufficient to explain the loops, the movements between the loops and the long-term tendency of the German Phillips Curve. It might well be that the German Phillips Curve and the corresponding regressions are spurious, but an allegedly missing co-integration of wage rate changes and unemployment rate is not the argument that could be drawn on to sustain this scepticism. On the contrary, both variables are co-integrated. To get a more detailed insight into the relationship, the two variables are split into a trend and a cyclical component by the help of the HP-filter. The results of regression analyses applied to the separated components support Phillips’ hypothesis of a negative relationship between wage rate changes and the unemployment rate.Wages, Unemployment, Phillips Curve
Inflation Forecasts and the New Keynesian Phillips Curve
No full textThe ability of the New Keynesian Phillips curve to explain US inflation dynamics when official central bank forecasts (Greenbook forecasts) are used as a proxy for inflation expectations is examined. The New Keynesian Phillips curve is estimated on quarterly data spanning the period 1970Q1-1998Q2 against the alternative of the Hybrid Phillips curve, which allows for a backward-looking component in the price-setting behavior in the economy. The results are compared to those obtained using actual data on future inflation as conventionally employed in empirical work under the assumption of rational expectations. The empirical evidence provides, in contrast to most of the relevant literature, considerable support for the standard forward-looking New Keynesian Phillips curve when inflation expectations are measured using official inflation forecasts. In this case, lagged inflation terms become insignificant in the hybrid specification. The usefulness of real unit labor cost as the preferred proxy for real marginal cost in recent empirical work on the Phillips curve is confirmed by our results.Money demand; Inflation; Phillips curve; Real marginal cost; Real-time data; GMM estimation
Clusters and Loops of the German Phillips Curve
No full textA preliminary regression analysis of different versions of the Phillips Curve on the basis of yearly data of the German economy from 1952 to 2004 leads to the conclusion that the original finding might still be of empirical relevance. A simple plot of seasonal adjusted quarterly data between the change of nominal wage rates and the unemployment rate shows a picture similar to that by which Phillips was inspired to his famous discovery: A long-term tendency of a negative, non-linear relationship coupled with minor deviations from this tendency forming sometimes so called loops. At fist sight, the Phillips Curve of Germany comprises clusters of data points and movements between these clusters. The clusters can be analysed and – together with the rest of data – dissolved into 12 (left or right turning) loops and 9 movements between these loops during the period from 1971Q1 to 2009Q4. In spite of the striking differences of these phenomena, a model with one regression equation is sufficient to explain the loops, the movements between the loops and the long-term tendency of the German Phillips Curve. This empirical finding contradicts several aspects with the ruling dogma of a Phillips Curve that broke down in the ‘70s and with the allegedly better fit of its replacements by augmented and modified Phillips Curves.Wages, inflation, unemployment, Phillips curve
