Unemployment and Productivity Growth: An Empirical Analysis within the Augmented Solow Model
Bräuninger, Michael; Pannenberg, Markus - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2000
Does a country's level of unemployment have an impact on the long-run growth rate? Incorporating unemployment into a … generalised Solow-type growth model, yields some answers. In the traditional Solow model, unemployment has no long-run influence … on the growth rate and the level of productivity. The long-run level of productivity is reduced if higher unemployment …

Cox-McFadden Partial and Marginal Likelihoods for the Proportional Hazard Model with Random Effects
Ondrich, Jan - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2005
In survival analysis, Cox's name is associated with the partial likelihood technique that allows consistent estimation of proportional hazard scale parameters without specifying a duration dependence baseline. In discrete choice analysis, McFadden's name is associated with the generalized...
