Dieser Aufsatz beschreibt neuere Entwicklungen in der Aggregationstheorie sowie ausgewählte empirische Arbeiten. Diese stellen exemplarisch dar, wie die Mikroökonometrie eingesetzt werden kann, um Aggregationsprobleme zu untersuchen und approximative Lösungen zu finden. Der Schwerpunkt liegt...

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 cumulated probability of ratification is about 13 per cent ten years after their adoption. In...
