In this paper we attempt to examine whether it is feasible to impute missing data values or not regarding the Quarterly Business Climate Survey of Institute for Economic and Enterprise Research. This subject implies the assessment of the missing data mechanism of the business climate questions and thereby the discussion of the possible imputation methods. But as we do not have sufficient information for analysing the missing data mechanism yet and the aim of the survey is to indicate the changes in some macroeconomic tendencies, we attempt to examine the situation with the assumption that the missing data mechanism is random. This paper presents an evaluation of the effects of multiple imputation from the aspect of the correlation between the GDP growth and the Quarterly Business Climate Index.
