In this research, non-linear inflationary dynamics based on the concept of missing money is studied using the threshold autoregressive models based on seasonal data of the time interval (1990:04-2016:07) for the economy of Iran. The finding of the research shows that simple and Divisia liquidity growth variables are determined as threshold variables, and inflation reacts to changes in the growt...

We consider dynamical models of supersymmetry breaking which naturally incorporate cosmological inflation. The inflaton plays an inevitable role in dynamical SUSY breaking and the hierarchical scales of inflation and SUSY breaking are simultaneously realized through a single dynamics.

This paper aims to explain the change in the rate of inflation within the United States economy by following a new Classical–Keynesian synthesis view and by incorporating private inflation expectations directly into the inflation determination process. A parsimonious unrestricted VAR approach is adopted to expose the longrun solution that is subsequently included in an error-correction model wi...

We consider inflation and debt dynamics under a global interest rate rule when private agents forecast using adaptive learning. Given the zero lower bound on interest rates, active interest rate rules are known to imply the existence of a second, low-inflation steady state. Under learning the economy can slip below this low-inflation steady state and be driven to an even lower inflation floor s...

In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

When it comes to measuring inflation persistence, a common practice in empirical research is to estimate univariate autoregressive moving average (ARMA) time series models and measure persistence as the sum of the estimated AR coefficients. We examine four potential sources of lag dynamics in inflation: the evolution of policymakers‟ willingness to stabilize output, shifts in the mean inflation...

In this paper we evaluate the empirical performance of a medium–scale DSGE model (Smets andWouters 2007) when agents form expectations about forward variables by using small forecasting models. Agents learn about these simple AR and VAR forecasting models through Kalman filter estimation and they combine them either using a prediction basedweighting scheme or fixed weights. The results indicate...

Recent studies by Gali and Gertler (1999) and Sbordone (2002) conclude that a theoretical inflation series implied by the forward-looking New Keynesian pricing model of Calvo (1983) fits post-1960 U.S. inflation closely. Their theoretical inflation series is conditional on (i) a reduced-form forecasting process for real marginal cost; and (ii) the calibration of the structural pricing equation ...

Our understanding of the state of the universe between the end of inflation and big bang nucleosynthesis (BBN) is incomplete. The dynamics at the end of inflation are rich and a potential source of observational signatures. Reheating, the energy transfer between the inflaton and Standard Model fields (possibly through intermediaries) and their subsequent thermalization, can provide clues to how...
