From its inception, big business in the western industrialised world has been organised in national business communities. Central elements of these business communities are corporate board interlocks that constitute the notorious ‘Old Boys Network’. This corporate elite connects the centres of corporate governance.This project investigates how the decline of the old boys network in the Netherlands has affected Dutch capitalism. Combining formal network analysis with insights from interviews with key corporate elite members, the project shows how during the last quarter of the 20th century the Dutch business community has disappeared. This is interpreted as a drift towards a liberal market economy. However, as the study shows, even in a liberal market economy corporate directors need social networks to communicate and coordinate their strategic decisions. Hence, the corporate elite shift its meeting network to privateand informal circles.The dataset contains the board composition of the largest 250 firms in the Netherlands, 1976, 1996 and 2001, the board interlocks between firms, and the meetings between directors.WorksheetsREAD ME (description of data)1976 Positions top 2501996 Positions top 2502001 Positions top 250Board Interlocks 1976Board Interlocks 1996Board Interlocks 2001Meetings Between Directors 1976Meetings Between Directors 1996Meetings Between Directors 2001
