The generation of trust between business partners is a strategic issue for firms in competitive agri-food markets. It is asserted that business associations can be important facilitators of trust between firms. Cross-national comparative research on the UK and Dutch potato industries is conducted to find out how and to what extent business associations perform functions that can facilitate trust. The results show that there are considerable national differences in the intensity and range of such functions performed by business associations. The findings indicate that, in spite of globalization trends, nationally distinct ways of generating trust via business associations continue to exist.
