“…Informal institutions such as trust, respect for others and confidence in individual self-determination encourage social interaction or reduce transaction costs, and thus may influence innovation performance as a result, as Tabellini (2010) proved based on research into 69 regions in eight European countries such as France, Germany (except East Germany and Berlin), the United Kingdom, Italy, the Netherlands, Belgium, Spain and Portugal. Moreover, based on research on 11 Eurozone countries -namely Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, the Netherlands, Portugal and Spain -from 1999 to 2013, Bonasia et al (2016) highlight the fact that trust in European institutions such as the European Central Bank, the European Commission or the European Parliament play a significant role in economic, political or social stability, which are key factors in high innovation performance.…”
