This paper applies Verdoorn's and Okun's law to derive efficient estimates of the employment and unemployment threshold in the Unified Germany. The analysis is built on a disaggregated dataset of regional labour markets, where spatial dependencies are taken into account. Especially, a spatial SUR model is proposed utilising the eigenfunction decomposition approach suggested by Griffith (1996, 2000 ). The thresholds turn out to be unstable over time. However, minimum output growth sufficient for a rise in employment is below the level needed for a drop in the unemployment rate. If spatial effects are ignored, the thresholds seem to be markedly overrated. [ABSTRACT FROM AUTHOR]
