The welfare costs of inflation and inflation uncertainty are well documented in the literature and empirical evidence on the link between the two is sparse in the case of Egypt. This paper investigates the causal relationship between inflation and inflation uncertainty in Egypt using monthly time series data during the period January 1974–April 2015. To endogenously control for any potential st...

We study the cosmological implications of including angular motion in the DBI brane inflation scenario. The non-canonical kinetic terms of the Dirac-BornInfeld action give an interesting alternative to slow roll inflation, and cycling branes can drive periods of accelerated expansion in the Universe. We present explicit numerical solutions demonstrating brane inflation in the Klebanov-Strassler...

We investigate the recently proposed natural double inflation model in supergravity. Chaotic inflation first takes place by virtue of the Nambu-Goldstone like shift symmetry. During chaotic inflation, an initial value of second inflation (new inflation) is set, which is adequately far from the local maximum of the potential due to the small linear term in the Kähler potential. Then, primordial ...

Between 1999 and 2006, there were two episodes during which inflation in the Rent index in the CPI diverged markedly from inflation in the index for Owner’s Equivalent Rent (OER); early in 2007, these series began to diverge again. Such divergence often prompts many to question CPI methods. A key difference between these two series is that OER indexes are based upon rents which have received a ...

Pacific Economic Bulletin Volume 21 Number 2 2006 © Asia Pacific Press For Fiji, which has been suffering persistent deficits since independence, determining the relationships between inflation, budget deficits, money supply, output, and import prices is essential. We find that inflation, deficits and money supply are cointegrated when inflation is the endogenous variable, and the long-run elas...

This article studies U.S. monthly inflation, inflation growth, and price level dynamics from January 1967 to September 2005. Two rolling samples are constructed to recover evidence about instability in inflation, inflation growth, and price level persistence and volatility. Evidence is presented that changes in inflation, inflation growth, and price level persistence and volatility coincide wit...

In the conventional view of inflation, the New Keynesian Phillips curve (NKPC) captures most of the persistence in inflation. The sources of persistence are twofold. First, the “driving process” for inflation is quite persistent, and the NKPC implies that inflation must “inherit” this persistence. Second, backward-looking or indexing behavior imparts some “intrinsic” persistence to inflation. T...

We not only reconstruct the slow-roll parameters for fit to the running spectral index from WMAP three-year data in the usual slow-roll inflation model and noncommutative inflation model, but also investigate the evolution of these slow-roll parameters. Requiring slow-roll inflation lasts more than 20 e-folds after CMB scales leave the horizon suggests that the potential at the last stage of in...

We consider hybrid inflation in the braneworld scenario. In particular, we consider inflation in global supersymmetry with the D-terms in the scalar potential for the inflaton field to be the dominant ones (D-term inflation). We find that D-term dominated inflation can naturally accomodate all requirements of the successful hybrid inflationary model also in the framework of D-brane cos-mology w...

decline in inflation in emerging market economies.1 By the end of 2000, average inflation in emerging markets had declined from triple-digit figures in the late 1980s to some 5 percent excluding a few outlier cases—Indonesia, Turkey, and Venezuela (Table 4.1). Such low levels of inflation have not been seen since before World War II, when, mostly under the discipline of the gold standard system...
