The results indicate that parameter estimates are robust to distributional assumptions, while estimates of duration dependence are not. Time aggregation does not seem to have drastic effects on the estimates in a simple parametric model like the Weibull, but can produce dramatic changes in the more complicated extended generalized gamma model. Semiparametric models for grouped data produce stable estimates, and perform much better than continuous\u2010time models in terms of significance at high levels of time aggregation.<\/jats:p>","DOI":"10.1002\/jae.3950070104","type":"journal-article","created":{"date-parts":[[2007,7,12]],"date-time":"2007-07-12T16:50:36Z","timestamp":1184259036000},"page":"5-30","source":"Crossref","is-referenced-by-count":50,"title":["Time aggregation and the distributional shape of unemployment duration"],"prefix":"10.1002","volume":"7","author":[{"given":"R.","family":"Bergstr\u00f6m","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.\u2010A.","family":"Edin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,11,7]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.2307\/1925542"},{"key":"e_1_2_1_3_1","unstructured":"Bergstr\u00f6m R.
