The problem is that the asymptotic validity of PANIC as a platform for constructing pooled panel unit root tests based on averaging is not fully proven. This paper provides the required results, whose usefulness is verified through simulations.<\/jats:p>","DOI":"10.1017\/s0266466609990351","type":"journal-article","created":{"date-parts":[[2009,10,26]],"date-time":"2009-10-26T10:57:29Z","timestamp":1256554649000},"page":"1851-1868","source":"Crossref","is-referenced-by-count":27,"title":["A NOTE ON THE POOLING OF INDIVIDUAL PANIC UNIT ROOT TESTS"],"prefix":"10.1017","volume":"25","author":[{"given":"Joakim","family":"Westerlund","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rolf","family":"Larsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2009,12,1]]},"reference":[{"key":"S0266466609990351_ref9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-9574.1978.tb01399.x"},{"key":"S0266466609990351_ref8","doi-asserted-by":"publisher","DOI":"10.1111\/1467-9892.00101"},{"key":"S0266466609990351_ref10","doi-asserted-by":"publisher","DOI":"10.1002\/jae.967"},{"key":"S0266466609990351_ref11","unstructured":"Westerlund J. & Larsson R.
