A procedure is developed for the recovery of the inflationary potential over the interval that affects astrophysical scales (≈ 1 Mpc−10 4 Mpc). The amplitudes of the scalar and tensor metric perturbations and their power-spectrum indices, which can in principle be inferred from large-angle CBR anisotropy experiments and other cosmological data, determine the value of the inflationary potential ...

The conduct of monetary policy in an oil economy with a managed floating exchange rate regime can be challenging in an environment of fiscal dominance and incomplete transition to a market economy. The Five-Year Development Plans provide a natural benchmark against which to assess monetary policy performance in Iran. Price stability has proved elusive, with liquidity growth targets constan...

I discuss the theoretical implications of the WMAP results, stressing WMAP’s detection of a correlation between the E-mode polarization and temperature anisotropies, which provides strong support for the overall inflationary paradigm. I point out that almost all inflationary models have a “vanilla limit,” where their parameters cannot be distinguished from a genuinely de Sitter inflationary pha...

The main objective of this paper is to investigate the effects of monetary regime (countries with inflation targeting monetary policy versus countries with exchange rate anchor) on the extent of exchange rate pass-through over the period of 1999-2010. To achieve this objective, the econometric model has been estimated by Dynamic Panel Data approach and Arrelano- Bond (AB) method. The empirical ...

We consider chaotic inflation in the theories with the effective potentials which at large φ behave either as φ or as e. In such theories inflationary domains containing sufficiently large and homogeneous scalar field φ permanently produce new inflationary domains of a similar type. This process may occur at densities considerably smaller than the Planck density. Self-reproduction of inflationa...

A proof is given that the maximal Fermi coordinate chart for any comoving observer in a broad class of Robertson-Walker spacetimes consists of all events within the cosmological event horizon, if there is one, or is otherwise global. Exact formulas for the metric coefficients in Fermi coordinates are derived. Sharp universal upper bounds for the proper radii of leaves of the foliation by Fermi ...
