This paper reports a comparison of South African household inflation expectations and inflation credibility
surveys undertaken in 2006 and 2008. It tests for possible feed-through between inflation credibility and
inflation expectations. It supplements earlier research that focused only on the 2006 survey results. The
comparison shows that inflation expectations differed between different income groups in both 2006 and
2008. Inflation credibility differed between male and female respondents, but this difference did not feed
through to inflation expectations.
More periodic survey data will be required for developing final conclusions on the possibility of feedthrough
effects. To this end the structure of credibility surveys should be reconsidered, as a large
percentage of respondents indicated that they ‘don’t know’ whether the historic rate of inflation is an
accurate indication of price increases.

Count data with structural zeros are common in public health applications. There are considerable researches focusing on zero-inflated models such as zero-inflated Poisson (ZIP) and zero-inflated Negative Binomial (ZINB) ...
