Observable quantities in cosmology are dimensionless, and therefore independent of the units in which they are measured. This is true of all physical quantities associated with the primordial perturbations that source cosmic microwave background anisotropies such as their amplitude and spectral properties. However, if one were to try and infer an absolute energy scale for inflation-a priori, on...

In contrast to conventional conditional mean approaches, this study uses quantile regression techniques to present some new statistical evidence on the link between inflation uncertainty and the level of inflation with cross sectional data in 161 countries for period from 1961-2002. We find new evidence that suggests positive inflation shocks have stronger impacts on inflation uncertainty acros...

The demands for an optimal ventilation apparatus are that it can be easily handled, achieves a sufficiently high ventilation volume, and minimizes gastric inflation. Our aim was therefore to carry out a study in a training mannikin to find out whether the Oxylator EM100, compared with the bag, obtains improved ventilation and a decrease in gastric inflation. In a randomized crossover study, 72 ...

T his paper investigates the asymmetric behavior of inflation. We use logistic smooth transition autoregressive (LSTAR) model to characterize the regime-switching behavior of Iran’s monthly inflation during the period May 1990 to December 2013. We find that there is a triple relationship between the inflation level, its fluctuations and persistence. The findings imply that the behavi...

Surfactant protein B (SP-B) deficiency has become increasingly recognized as a cause of severe prolonged respiratory distress. However, little has been reported with regard to the genetic variability of SP-B in Chinese infants with neonatal respiratory distress syndrome (RDS). One case of a Chinese male infant with neonatal RDS was analyzed for clinical manifestation and genetic variability of ...

Given the effects of inflation on the decline of household welfare and its impact on production and investment, identifying the factors affecting it in order to adjust inflation and achieve price stability is necessary. Therefore, using the TVP-FAVAR model, which differentiates the fluctuations in factors affecting inflation, we try to identify the effects of different shocks such as liquidity,...

This paper empirically investigates the relationship between CPI inflation uncertainty, and private investment in the Iranian economy from 1988 to 2010 by using quarterly data. We employ a bivariate VAR(5)-GARCH(1,1)-in-mean with diagonal BEKK model to discover in a unified framework how are the interactions between the variables. In the model, conditional variance of inflation and private inve...

this paper examines the idea that the rate of inflation tends to increase nominal government expenditures faster than government revenues. it concludes that while government expenditures rise concurrently with inflation, real government revenues tend to fall based on collection tags. empirical results using time series data for iran support our expectations in which the longer is the delay in g...

in literature about inflation targeting, main factor is interest rate. in new surveys, price of some assets as housing is important in inflation targeting. iran inflation targeting is based on money changes and is not based on interest rate and housing price. in this paper, we want to survey problems of wrong policy of iran policy makers. we reveal that, using rate of deposit profit and growth ...

Purpose The objectives of this study are twofold. First, it intends to investigate the symmetric link between initial public offering (IPO) variability and determinants stock market index, treasury bill rate, inflation, GDP growth rate foreign direct investment. Second, examine asymmetric IPO aforementioned determinants, namely Design/methodology/approach Data from 1992 2018 were gathered count...
