in the Einstein frame. As a result, the inflationary scenario associated to this potential or to an action including an term are referred to as Starobinsky inflation. To distinguish, models using the original, more complete, quantum effective action are then called (trace)-anomaly induced inflation.
Paul Steinhardt, one of the original architects of the inflationary model, introduced the first example of eternal inflation in 1983. [97] He showed that the inflation could proceed forever by producing bubbles of non-inflating space filled with hot matter and radiation surrounded by empty space that continues to inflate.
Other economic concepts related to inflation include: deflation – a fall in the general price level; [17] disinflation – a decrease in the rate of inflation; [18] hyperinflation – an out-of-control inflationary spiral; [19] stagflation – a combination of inflation, slow economic growth and high unemployment; [20] reflation – an ...
When there is a BOP disequilibrium, either by the market forces or policy measures for readjustments, SWAN model is helpful. Internal Balance looks forward to acquiring full employment with lowest possible inflation, whereas External Balance looks towards a "No surplus - No deficit" position in the economy.
The non-accelerating inflation rate of unemployment (NAIRU) [1] is a theoretical level of unemployment below which inflation would be expected to rise. [2] It was first introduced as the NIRU (non-inflationary rate of unemployment) by Franco Modigliani and Lucas Papademos in 1975, as an improvement over the "natural rate of unemployment" concept, [3] [4] [5] which was proposed earlier by ...
Linde continues his work on the theory of inflationary multiverse. In particular, Renata Kallosh and Andrei Linde, together with their collaborators, developed a theory of cosmological attractors. This is a broad class of versions of inflationary cosmology which provide one of the best fits to the latest observational data. [5]
In Robert J. Gordon's triangle model of inflation, the current inflation rate equals the sum of demand-pull inflation, cost-push inflation, and built-in inflation. "Demand-pull inflation" refers to the effects of falling unemployment rates (rising real gross domestic product ) in the Phillips curve model, while the other two factors lead to ...
The Inflationary Universe is a popular physics book by theoretical physicist Alan H. Guth, first published in 1997. The book explores the historical and theoretical development and expansion of the theory of inflation , which was first presented by the author in 1979 as the culmination of his research on the implications of theory of the Big Bang .
