Not sufficiently harmonised national pension systems within the European Union distort the allocation of labour and endanger redistributive activities. This paper identifies the most decentralised level of harmonisation which guarantees efficient allocation and enables redistribution. For this,...

This paper investigates the inter-temporal structure of implicit taxes that arise in unfunded pension schemes. We demonstrate that these tax rates are declining over the life cycle. Using German micro-data for men and married women we estimate periodic wage elasticities of labour supply in order...
