We demonstrate the existence of chaos in realistic models of two-field inflation. The chaotic motion takes place after the end of inflation, when the fields are free to oscillate and their motion is only lightly damped by the expansion of the universe. We then investigate whether the presence of chaos affects the predictions of two-field models, and show that chaos enhances the production of to...

The paper shows that Liquidity Deflation, a liquidity-drainage mechanism associated with Safe Asset Shortage, helps to rationalize supply-side liquidity trap and involuntary unemployment under wage/price flexibility, especially in economies that suffered massive liquidity destruction, like advanced economies in the wake of the Lehman crisis. Moreover, Liquidity Deflation is shown to imply defla...

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic volatility process. We develop a Monte Carlo maximum likelihood method to obtain efficient estimates of...

We calculate the NAIRU for the U.S. in a framework where inflation and the unemployment rate can respond to each other. The NAIRU is defined as the component of the actual unemployment rate that is uncorrelated with inflation in the long run. Using a structural VAR approach, the NAIRU and core inflation can be estimated simultaneously. Our estimation results show that the NAIRU falls dramatical...

Recent increases in pathology costs per scheme member are a concern to medical schemes and pathologists alike. To better understand the observed increasing costs, the National Pathology Group commissioned Prognosys to analyse the trends affecting these increases. We found that these increases are driven by inflation, increases in utilisation, and redistribution of the burden of cost. The identi...

Many central banks conduct monetary policy according to an inflation targeting framework, which requires that some measure of inflation be chosen as the target. One approach would be to use an index of goods and services whose prices are market determined and not subject to frequent, idiosyncratic, and transitory changes. That could be an index based on the personal consumption expenditures pri...

Inflation is an important phenomenon in the national economy, and central banks have made it one of their tasks to control inflation. The core research object this paper causes inflation China since entered 21st century, Entropy-weighting Method used construct a comprehensive indicator system, including 5 different factors contributing inflation, then analyze using VAR model. following conclusi...

A prominent policy issue of the 1970s and one that seems certain to dominate the early 1980s is the appropriate response to a prevailing high rate of inflation. The view that there is a long-run trade-off between inflation and unemployment, widely accepted at the end of the sixties, is now held by only a small minority of economists. It is still widely believed, however, that there is a short-r...

We inspect how inflation target announcements are instrumental in building central bank credibility and shaping the public’s inflation expectations. Investigating the role of announcements in two early adopters of inflation targeting by using a time varying credibility measure, we find that both the accuracy and the frequency of inflation announcements have a positive impact on how much attenti...
