Introduction: the role of entrepreneurship in economic development It is widely recognised in the literature (Acs and Audretsch, 2003; Audretsch and Keilbach, 2004; Baumol, 2002) that entrepreneurial activity is among the most important determinants of the different economic performances of countries. Entrepreneurship activities and especially small-business activities have been connected to job creation (Audretsch et al, 2001; Bridge et al, 2003; Storey, 1994), economic competitiveness (CEC, 2004; Schumpeter, 1945), innovation, especially in skill-intensive industries in developed countries (Beck et al, 2003), and`imitation processes' in developing countries (Baumol, 2002). Moreover, although the above-summarised roles can be fulfilled in every context, the encouragement of entrepreneurship and the small-business sector in transition economies was based on the very unbalanced structure of entrepreneurial organisations with a focus on big firms, as functional to central planning but abnormal to a market economy (Chilossi, 2001; Smallbone and Welter, 2001). In these contexts, transition economies could also introduce more flexible production processes and a wider range of products to consumers, considering the inflexibility of production processes inherited from central planning (Smallbone and Welter, 2001). The evidence so far shows that the small and medium-sized enterprise (SME) sector developed spontaneously at the beginning of transition. Recently, governmental initiatives have been designed in various countries to support the`grass-roots development' of the SME sector. Despite the`bottom-up transformation' that has happened in some countries, such as Poland or Hungary, there is consensus in the literature over the role that institutions play in entrepreneurship and SME development which have constrained the development of this sector for many years, as crosscountry survey evidence has proved (
