Small Business Redefined: A Quasi-Linear Fuzzy Classification of Firm Size

The quasi-linear fuzzy modelling of Filev (1991) is used to estimate the relationship between the number of managers and employees in a firm. The results form the basis for the classification of firms into small and large businesses. Application to a data of Australian firms shows an evolution episode during which firms are driven by various transitional forces. The composition of the transition region suggests that the 2011 small business tax-break cap set by Australian Taxation Office falls short of fully supporting growth as intended. The implications pave the way for improvement to the business tax code aiming at growth and job creation.
