Gråsjö, UrbanFlood, Lennart2006-11-302007-02-092007-02-091998http://hdl.handle.net/2077/2680This study focuses on a comparison and evaluation of models and estimators appropriate for time-use data. The tobit type I as well as different generalizations are used. According to our findings, a simple tobit I method can produce results that are similar and in some cases even better to the much more sophisticated methods. This is especially true if the participation or index equation is incorrectly specified.17 pages54402 bytesapplication/pdfenTime use data; sample design; Monte Carlo; tobit; generalized tobitReportEconomics
