T his empirical analysis endeavors to trace out the causal nexus between core inflation and economic growth from the perspective of twenty worlds’ leading economy with the help of the nonlinear Granger causality approach by using time series data from 1981 to 2016. Based on nonlinear Granger causality results, it has been found that there is unidirectional casualty running from core ...

T he world economy has experienced a bulk of positive and negative shocks in crude oil prices and exchange rates over the years, and that global inflation has undergone some changes. Such shocks have affected the macroeconomic variables in the countries of the world and have challenged the economies of these countries, and have led them to take different measures to protect themselves agai...

This paper investigates the forecasting accuracy of the trimmed mean inflation rate of the Personal Consumption Expenditure (PCE) deflator. Earlier works have examined the forecasting ability of limited-influence estimators (trimmed means and the weighted median) of the Consumer Price Index but none have compared the weighted median and trimmed mean of the PCE. Also addressed is the systematic ...

In this paper the long-run trend in CPI inflation (core inflation) for the US over the 1960– 2000 period is estimated using a common trends model. In this framework, core inflation is interpreted and constructed as the long-run forecast of inflation conditional on the information contained in nominal money growth, output fluctuations and movements in the oil price. Unlike other commonly used me...

This paper provides a review of the concept of core inflation and evaluates the performance of several proposed measures. We first consider the rationale of a central bank in setting its inflation goal in terms of a selected rate of consumer price growth and the use of a core inflation measure as a means of achieving this long-term policy objective. We then discuss desired attributes of a core ...

Economists have not been altogether successful in their efforts to forecast “core” inflation—an inflation measure that typically excludes volatile food and energy prices. One possible explanation is that the models used to make these forecasts fail to distinguish the forces influencing price changes in core services from those affecting price changes in core goods. While core services inflation...
