The first conference took place in 1980, in Ronneby, Sweden and since then it has been a biannual event organized in Nordic Countries. Now for the first time the conference is organized outside the Nordic countries. It is a great pleasure for Tallinn School of Economics and Business Administration at Tallinn University of Technology to invite and welcome senior as well as junior researcers from Nordic and Baltic countries, as well as researches from other European countries and overseas to Tallinn, Estonia to the 15th Nordic Conference on Small Business Research: Challenges for Enterpreneurship and Small Business Development in the Context of European Enlargement.
