We show that inflation can occur in the core of a Q-ball.

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We develop a two-sector new-Keynesian model to evaluate different inflation targeting rules in economies with financial frictions. We conclude that, in the presence of financial frictions, a welfaremaximizing central bank should adopt flexible head...

This paper examines alternative statistically-based measures of core inflation in Ireland over the period 1976-1999. A highly disaggregated (approximately 500 price series) dataset from the Irish HICP is used. The distribution of quarterly price changes is shown, in common with other international studies, to be highly kurtotic (i.e., fat-tailed) and right skewed. This would suggest there is co...

Meanwhile, having generally enjoyed low and stable prices since the early 2000s, most of the key economies in the world are now going through the final phase of a boom and bust cycle in asset (housing) prices based upon liquidity expansion, owing to sustained low interest rates and financial market innovations such as derivatives. In this regard, the argument may be put forward that monetary po...

In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

Euro area inflation stubbornly above 2 per cent Headline inflation in the euro area has, on average, remained stubbornly above 2 per cent -the upper limit of the European Central Bank’s definition of medium-term price stability -for most of the period since mid-2000. This persistence may seem puzzling in the light of weakness in activity and is only partly explained by factors like oil and food...

Recent work in the macroeconometric literature considers the problem of summarising efficiently a large set of variables and using this summary for a variety of purposes including forecasting. This paper applies a new factor extraction method to the extraction of core inflation and forecasting of UK inflation in the recent past. JEL Codes:C13, C32

The aim of this study is to examine the nonlinear effects of fiscal and monetary policies on inflation during 1990:3 to 2013:1 based on threshold model. First lag of the liquidity growth is recognized as threshold variable with threshold value estimated at 6.37 percent. In low liquidity growth, the results indicate that inflation expectations and the lagged liquidity growth are the most importa...
