The objective of this paper is to present evidence on the extent and the determinants of firms’ market share stability in Greek manufacturing industry for 1989-1992. Results find that market share stability is reinforced by large initial industry size, low growth rates and, to a lesser extent, by low exit and high entry rates within the group of incumbent firms. Two variables, concentration level and innovative intensity, tend to have differentiated effects on mobility according to the sample taxonomy used. Further work is suggested in testing the hypotheses for a longer period so as to allow for possible effects of product and/or business cycles.
