چکیده
In this work, I consider an inflation model with a quadratic potential and negative cosmological constant. An analytical solution of the equation motion for inflaton field is found without slow-roll approximation. The result that rolling at constant speed. prediction perturbation calculated.

Stochastic Steiner Tree with Non-uniform Inflation
We study the Steiner Tree problem in the model of two-stage stochastic optimization with non-uniform inflation factors, and give a poly-logarithmic approximation factor for this problem. In this problem, we are given a graph G = (V,E), with each edge having two costs cM and cT (the costs for Monday and Tuesday, respectively). We are also given a probability distribution π : 2 → [0, 1] over subs...
متن کاملOn the Optimal Inflation Rate
How do financial frictions affect the optimal inflation rate? Can financial frictions alone annul the long-run super-neutrality of money? Should the inflation rate be higher in emerging market economies with less developed financial markets than in advanced economies, as is currently observed? To answer these questions we set up an incomplete markets model in which households choose portfolios ...
متن کاملThe Optimal Rate Of Inflation∗
Observed inflation targets around the industrial world are concentrated at two percent per year. This chapter investigates the extent to which the observed magnitudes of inflation targets are consistent with the optimal rate of inflation predicted by leading theories of monetary nonneutrality. We find that consistently those theories imply that the optimal rate of inflation ranges from minus th...
متن کاملStudy of the Relationship between Inflation Rate and Bank Interest Rate in the Iranian Economy
Experts believe that by lowering the interest rate on bank accounts, total cost of goods and services decreases, and secondly, investment production increases, both of which lead to lower inflation and provide stable employment field, on the other hand, are concerned about the negative effects of lowering the interest rate without lowering inflation and know the underlying requirement of nomin...
متن کاملDoes European Monetary Union make inflation dynamics more uniform?
Using a nonparametric method to characterize Markovian operators, we describe the evolution of the short-run inflation processes among the EMU countries between 1996 and 2012. While a progressive clustering pattern can be outlined in the first half of the period showing that the monetary union makes price dynamics more homogeneous starting from 2004 an increase in price volatility makes the clu...
