“Eternal inflation” is often confused with “chaotic inflation”. Moreover, the term “chaotic inflation” is being used in three different meanings (all of them unrelated to eternal inflation). I make some suggestions in an effort to untangle this terminological mess. I also give a brief review of the origins of

There are more than twenty widely used e-indexes which are used to measure ICT Adoption all over the world. It might be a problem to choose ones to analyze the ICT dynamics or to compare the levels of ICT development in different regions of the world. So first the most common eindexes were reviewed. Then the comparative analysis of the e-indexes structure has been done. The coherence of the e-i...

Theory and extant empirical evidence suggest that the cross-sectional asymmetry across disaggregated price indexes might be useful in forecasting aggregate inflation. Trimmed-mean inflation estimators have been shown to devices for headline PCE But is this because they signal underlying trend or implicitly distribution? We address question by augmenting a "hard" beat benchmark model with robust...

Measuring the similarity between clusterings is a classic problem with several proposed solutions. In this work we focus on measures based on coassociation of data pairs and perform some experiments to investigate whether specificities can be highlighted in their behaviour. A unified formalism is used, which allows easy generalization of several indexes to a fuzzy setting. A selection of indexe...

ranking fuzzy numbers plays a very important role in decision making and some other fuzzy application systems. many different methods have been proposed to deal with ranking fuzzy numbers. constructing ranking indexes based on the centroid of fuzzy numbers is an important case. but some weaknesses are found in these indexes. the purpose of this paper is to give a new ranking index to rank vario...

The paper researches on the inflation level forecasting for China and the United States in one kind of univariate and three kinds of bivariate cases, using Vector Autoregressive and Bayesian Vector Autoregressive Models, based on the rolling-sample forecasts and the mean absolute percentage error standard. Empirical tests show that, both China and the United States’ inflation level series are s...

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...

in present paper, first the concept of informal economy and its place in the economic literature has been described. then the causes and factors involved in providing the informal sector was examined and the volume of informal economy was estimated. second, the effect of inflation on informal economy was surveyed. to estimate the volume of informal sector, residual discrepancy method was used a...

In many interval computation methods, if we cannot guarantee a solution within a given interval, it often makes sense to “inflate” this interval a little bit. There exist many different “inflation” methods. The authors of PASCAL-XSC, after empirically comparing the behavior of different inflation methods, decided to implement the formula [x−, x]ε = [(1 + ε)x− − ε · x, (1 + ε)x − ε · x−]. A natu...
