According to Johns Hopkins University professor of applied economics Steve Hanke, the Ghana Statistical Service is incorrect in saying that his calculation of Ghana’s inflation has a “serious weakness.”
He claims that government statistician Professor Samuel Kobina Annim has to spend some time reading scholarly material.
Samuel Kobina Annim, a statistician at the Ghana Statistical Service, asserts that my measure of inflation for Ghana has a “serious shortcoming.”
Wrong. Prof. Annim ought to read some of the academic literature.
“Ghana Statistical Service statistician Samuel Kobina Annim casts doubt on my measure of Ghana’s inflation rate. Today, using the tried-and-true purchasing power parity method, I measure inflation in Ghana at 98%/yr. Annim should take notes,” Prof. Steve Hanke tweeted on Saturday, October 15.
Prof Samuel Kobina Annim cautioned Ghanaians against comparing the Statistical Services inflationary figures with that of popular US Professor Steve Hanke.
He told the media at the October briefing on the nation’s inflation that the CPI method adopted by the Statistical Service is consistent with international practice and superior to Prof Hanke’s Purchasing Price Parity Module (PPPM), adding that Prof Hanke’s PPPM is only based on the exchange rate.
“Steve Hanke’s approach is not based on the consumer price index, Steve Hanke’s approach is based on the purchasing power parity. Underlying the purchasing power parity is the assumption that price differences between [the] two countries are only the exchange rate.
“The key difference here is that the CPI approach necessarily requires that you collect data on three variables: prices, quantities and the expenditure weight of these items, and this is at sharp variance with Steve Hanke’s purchasing power parity.
“The premise of the computation both from a data point of view and a scope of data point of view are not the same, so we need not make an attempt to compare that,” Prof Annim explained.
Ghana’s inflation rate according to the Ghana Statistical Service has moved from 33.9 per cent in August 2022 to 37.2 per cent in September 2022.
This is a 2.0 per cent month-on-month increase from the 33.9 per cent rate recorded in August 2022.
However, the rate is also 37.2% higher than that of September 2021.
Year-on-Year inflation varied upwardly by 2.2 percentage points between August (31.7%) and September (33.9%) 2022.
Food inflation was 37.8% while non-food inflation was 36.8%.
Inflation for locally produced items was 35.8% while inflation for imported items was 40.7%.
