| Title | Semiparametric estimation in sample selection models for quarterly data |
| Participants | Montezuma B.G. Dumangane, Delger Enkhbayar, Nicoletta Rosati (Principal Investigator) |
| Summary | The estimation of quarterly models, which has gained increasing interest in many areas of economics, has often to deal with deficiencies of the data, many times due to non-random selection of the samples. In fact, because of the higher frequency of the data, in order to reduce the sample size, the units under observation are usually selected according to specific mechanisms, which often lead to nonrandom samples. This project aims at studying a type of sample selection models where the selection mechanism is known, but outlines a procedure which can easily be adapted to other cases. |
