We point out that for a class of ‘new inflation’ models in supergravity the required initial value of the inflaton field is dynamically set if there is another inflation (‘pre-inflation’) before the ‘new inflation’. We study the dynamics of both inflatons by taking a hybrid inflation model for the ‘pre-inflation’ as an example. We find out that our ‘new inflation’ model provides reheating tempe...

Warm inflation dynamics is reviewed. Results on dissipative scalar field dynamics relevant to warm inflation are examined and estimates of radiation production are given.

This paper compares sticky-price and sticky-information Phillips curves empirically considering inflation dynamics in eleven countries (the G7 and Scandinavia). We evaluate the models‘ abilities to match empirical second moments of inflation. Although overall model performance is similar, there is a strong systematic pattern in model performance by moment type. Sticky prices match unconditional...

Despite the many studies on the dynamics of inflation, much still remains to be done in the context of understanding several aspects concerning the microscopic dynamics underlying many of the models for inflation, particularly in those cases where the inflaton is coupled to several other fields, like in hybrid inflation models and supersymmetric (SUSY) model extensions. In most of these models ...
