Abstract:
There are over 180 ILO conventions in many areas of labour law, industrial relations and social security, but they are not ratified universally: for the conventions adopted between 1975 and 1995, the cumulative probability of ratification is about 13 percent 10 years after their adoption. In this paper, the ratification decision is understood as a transition between two states. Using duration analysis, we identify circumstances which are favourable to this transition. For industrialized countries, the ratification of ILO conventions is shown to depend on internal political factors such as government preferences or the power of left-wing parties in parliament. For developing countries, economic costs of ratification have a significant impact. There is no evidence for external pressure in favour of ratification. Among industrialized member states, there is a clear downward trend in estimated ratification probabilities over the last two decades. Copyright 2001 Blackwell Publishers Ltd.
