Stochastic Inflation : New Results 1
نویسنده
چکیده
We prove that, in stochastic approach, there exists an equivalence relation between different inflationary models under some redefinition of field and time variables. The postinflationary physics is insensitive to it and one can say that related theories are in fact indistinguishable from the viewpoint of a local observer. We discuss the methodology of cosmology as a branch of natural science and present a general prescription for the interactive development of cos-mological theory and observations avoiding the problems of freedom in the choice of different variants of the theory and unobservability of superhorizon scales. Also we present all " exactly solvable " inflationary models in slow rolling regime.

The Effects of Monetary Policy on Output and Inflation in Afghanistan: A Dynamic Stochastic General Equilibrium Approach
T he consequences of the decisions and policies taken for the reconstruction of Afghanistan during the past decade, showed that there should be paid more attention to the monetary policies. There is also a question that whether monetary policies have the potential to affect the production and inflation in Afghanistan or not. The aim of this paper is to explore this effect by designin...
متن کاملMonetary and Fiscal Policy Interaction in Iran: A Dynamic Stochastic General Equilibrium Approach
Achieving the goals of price stability, sustainable economic growth, and the improvement of many economic variables require coordination between the monetary and financial authorities. In this study, a new modified Keynesian stochastic dynamic equilibrium general equilibrium model is introduced for Iran and in the framework of game theory, optimal policy of fiscal and monetary authorities are d...
متن کاملEffect of Sentiments on Macroeconomic Variables in Iran: A Dynamic Stochastic General Equilibrium Approach
This study aims to evaluate the effect of sentiments on Iran's economy through a New Keynesian Dynamic Stochastic General Equilibrium model in a closed economy. In this study, the coefficients of the proposed model are calibrated and estimated using the quarterly data of Iran's economy from 2004 to 2015. It shows that in the presence of sentiment, how stochastic impulses affect the main macroec...
متن کاملThe Role of International Financial Integration in Production and Inflation Fluctuations in Iran: Using a Dynamic Stochastic General Equilibrium Model
The effects of International financial integration on the fluctuations of variables in response to shocks are a matter of heavily concentrated literature of the business cycle in recent years. In this paper, a New Keynesian DSGE model is developed in which there is a channel for capital account changes through the foreign deposit's inflow and outflow. Then the effects of financial integration a...
متن کاملA New Theory of Stochastic Inflation
The stochastic inflation program, first initiated by Starobinsky, is a framework for understanding the dynamics of a quantum scalar field driving an inflationary phase. Though widely used and accepted, there have over recent years been serious criticisms of this theory. In this paper I will present a new theory of stochastic inflation which avoids the problems of the conventional approach. Spec...
متن کاملOn the Pricing of Inflation-Indexed Caps
We consider the problem of pricing inflation-linked caplets in a BlackScholes-type framework as well as in the presence of stochastic volatility. By using results on the pricing of forward starting options in Heston’s Model on stochastic volatility, we derive closed-form solutions for inflations caps which aim to receive smile-consistent option prices. Additionally we price options on the infla...
