A survey of the new theories of inflation that have developed over the past two decades in response to the inflationary pressures experienced by Western countries examines the shifting debate from explaining inflation as a "causal" process to explaining its increase as a Reviews: 1.   A recent post, Insurance Agents and Determining Coverage Limits for Buildings, generated a number of very interesting comments about the differences between Replacement Cost Value of a building and the Reconstruction Value of a is a difference between the two values and it is a big issue.

This volume presents the latest thoughts of a brilliant group of young economists on one of the most persistent economic problems facing the United States and the world, inflation. Rather than attempting an encyclopedic effort or offering specific policy recommendations, the contributors have emphasized the diagnosis of problems and the description of events that economists most thoroughly Reviews: 1. A. Reconstruction would lead to an increase in GDP. B. Increased government spending on relief efforts in the U.S. would decrease GDP. C. Lost items and buildings would lead to a decrease in GDP. D. U.S. well-being was improved, despite the loss in GDP.

Panel (a) shows potential output (the blue line) and actual real GDP (the purple line) since Panel (b) shows the gap between potential and actual real GDP expressed as a percentage of potential output. Inflationary gaps are shown in green and recessionary gaps are shown in yellow.   The International School for Advanced Studies (SISSA) was founded in and was the first institution in Italy to promote post-graduate courses leading to a Doctor Philosophiae.

To first order in the deviation from scale invariance the inflationary potential and its first two derivatives can be expressed in terms of the spectral indices of the scalar and tensor perturbations, n and n T, and their contributions to the variance of the quadrupole CBR temperature anisotropy, S and T.

In addition, there is a ``consistency relation'' between these quantities: nTCited by: We discuss the overall strategy of perturbative reconstruction and 7 S derive the second-order expressions for the inflationary potential and its first two derivatives and the first-order expression for its third derivative, all in terms of n, nT, S, T, and dn/d lnk.

We discuss the overall strategy of perturbative reconstruction and derive the second-order expressions for the inflationary potential and its first two derivatives and the first-order expression for its third derivative, all in terms of n, n T, S, T, and dn=d ln k.

The inflationary potential for the constant slow-roll inflation is then reconstructed in the framework of both general relativity and the scalar-tensor theory of gravity, and compared with the.

3. Second-order slow-roll approximation For a reconstruction of the potential U(O) under the "umbrella" of chaotic inflation, we adopt here the equations of Stewart and Lyth [7] for the second order slow-roll approximation.

Inflationary potential κ U (y=H 2) for m=1 (potential function until y=) and m=2 (until y=17). The two lines correspond to κ U =2y and κ U =3y, the boundaries of the inflationary phase. A new method is applied to reconstruct the inflationary potential from a more phenomenological point of view.

By using the more stringent nonlinear second order slow-roll approximation, we found, besides the power law inflation forns < 1, an exact solution for which the spectral index is necessarily determined as ns ~= Part of these continuous and discrete spectra.

We derive a lower bound on the field excursion for the tachyon inflation, which is determined by the amplitude of the scalar perturbation and the number of e -folds before the end of inflation.

For the slow-roll inflation, the assumed relation leads to the reciprocal relation between the Gauss-Bonnet coupling function ξ(ϕ) and the potential V(ϕ), and it leads to the relation r=16(1-λ)ε1 that reduces the tensor-to-scalar ratio r by a factor of 1-λ.

The end of the inflation after World War II was also reasonably favorable, accompanied as it was by only a relatively mild recession. But more recent experience in the United States indicates that.

Exponential potential models, the simplest hybrid inflationary models, and monomial potential models of degree n > 2 do not provide a good fit to the data.

Planck does not find statistically significant running of the scalar spectral index, obtaining d n s / d l n k = − ± d n_s/d ln k = \pm d n s / d l n k.

We make a more general determination of the inflationary observables in the standard four-dimensional (4D) and five-dimensional (5D) single-field inflationary scenarios by the exact reconstruction of the dynamics of the inflation potential during the observable inflation with a minimal number of assumptions: the computation does not assume the slow-roll approximation and is valid in all.1.

A mathematical model of membrane action potentials of mammalian ventricular myocardial fibres is described. The reconstruction model is based as closely as possible on ionic currents which have been measured by the voltage-clamp method. 2. Four individual.The Great Inflation was the defining macroeconomic event of the second half of the twentieth century.

Over the nearly two decades it lasted, the global monetary system established during World War II was abandoned, there were four economic recessions, two severe energy shortages, and the unprecedented peacetime implementation of wage and price controls.
