economy is operating in the region of price stability, public expectations and beliefs about the central bank’s plans and objectives, always important, become even more so. First, because the public can no longer safely assume that the central bank prefers lower to higher inflation, expectations about future policy actions and future inflation may become highly sensitive to what the public perc...

This paper examines the effects of inflation and currency substitution volatility on the average rates of inflation and currency substitution for twelve emerging market economies. Using a bivariate GARCH-in-Mean model, which accommodates for asymmetric and spillover effects of inflation and currency substitution innovations on their volatilities, we find that for the majority of the countries i...

While there is no consensus about the history of time since the beginning, in this paper I will discuss some possibilities. We have a pretty clear picture of cosmic history from the electroweak phase transition through the time of recombination, a period which includes the QCD phase transition and big bang nucleosynthesis. This paper includes a quantitative discussion of the age of the universe...

The study investigates the time-varying dynamics between inflation and uncertainty in India using recently developed Stochastic Volatility Mean with a Time-varying Parameter (TVP-SVM) model. results reveal that significantly raises rate throughout estimation period. Furthermore, reacts positively to rise past rates. are consistent Cukierman-Meltzer Friedman-Ball hypotheses. Reserve Bank of must...

Abstract Research background: Price stability plays a crucial role in ensuring stabilities the financial markets as well real sector. Despite this, questions are still raised, querying if it is either inflation, inflation uncertainty or combination of both, which affects economic growth? The results obtained, both theoretically and empirically, differ. This paper seeks to revisit provide theore...

An elegant approach, which incorporates the effect of the stringy spacetime uncertainty relation, to calculate power spectra of fluctuations during inflation has been suggested by Brandenberger and Ho. In this approach, one of important features is the appearance of an upper bound on the comoving momentum k, at which the stringy spacetime uncertainty relation is saturated. As a result, the time...

In this paper we revisit the formulation of scalar field theories on de Sitter backgrounds subject to the generalized uncertainty principle (GUP). The GUP arises in several contexts in string theory, but is most readily thought of as resulting from using strings as effective probes of geometry, which suggests an uncertainty relation incorporating the string scale ls. After reviewing the string ...
