Regarding the trade-off between the depth and the duration of recessions, there exists a mounting empirical evidence of … GDP in depth and a relative difference of 3 years duration can be attributed to this parameter. Overlooked for decades …, this missing parameter hypothesizes that Frisch's 'rocking-horse theory' of the business cycle is an inaccurate description …

We investigate why we observe non-negative duration dependence among young unemployed men in urban Ethiopia. Assuming … that genuine duration dependence is negative, there are five explanations for a non-decreasing hazard: the presence of … is the only convincing one. We also establish that genuine duration dependence is indeed negative in the long run. …
