The paper considers a two-sector economy with a constant population: The public sector, with stable productivity, and a private sector, with productivity growth. Baumol's law says that such an economy has no steady state. It is demonstrated what this means. Two attempts to uphold a policy that...

The effects of systematic sampling and temporal aggregation on the seasonal cycle model (see Miron, 1993) and the seasonally integrated process (see Hylleberg et al., 1990) are discussed. The temporal aggregation theory is used to improve the sequential test for monthly seasonal unit roots of...

We exploit a rich high quality register-based employer-employee panel data set to investigate the incidence and intensity of government co-sponsored training for the Danish adult population. We focus specifically on training over the working life cycle and find that the levels of participation...
