Abstract: This study demonstrates a challenge of building and validating a model of factors associated with long-term economic success of economies, as reflected by measures of their aggregate value of output/income per capita. We use two quantitative modelling techniques including multiple linear regression (MLR) and a newer technique of soft regression, a modelling tool based on fuzzy information processing technology. The objective of this study is to test and compare the two information-processing tools to find the more reliable and potentially helpful tool for policy decision making. The conclusions of this study are: 1) the soft regression tool generated more consistent and comprehensible results in comparison to the MLR method; 2) based on soft regression tool, the model displayed solid stability over extensive period under study; 3) based on MLR method, we could interpret the results as supporting the validity of the model; however, some of the results were contradictory, thus undermining the reliability of conclusions.

Keywords: multiple linear regression; MLR; soft regression; fuzzy information processing; economic growth; international competitiveness.
