These equations are called seemingly unidentified \nstructural equations. The key to the identifiability of these \nequations is that the right-hand-side endogenous variables undergo \nstructural changes with respect to the exogenous and\/or \npredetermined variables. To estimate the seemingly unidentified \nstructural equations, this paper uses the classical minimum \ndistance (MD) estimator and the principal components instrumental \nvariables (PCIV) estimator. The PCIV estimator is different \nfrom conventional IV estimators for structural equations in \nthat nonlinear functions of exogenous and\/or predetermined \nvariables are used as instruments. Simulation results comparing \nthe estimator efficiency of the MD and PCIV estimators are reported \nin this paper. The results indicate that the MD and PCIV estimators \nare complementary to each other. The estimation methods proposed \nin this paper are applied to the Japanese export and GDP data \nto study the effect of export growth rate on that of GDP.<\/jats:p>","DOI":"10.1017\/s0266466602183095","type":"journal-article","created":{"date-parts":[[2002,12,11]],"date-time":"2002-12-11T22:13:26Z","timestamp":1039644806000},"page":"744-775","source":"Crossref","is-referenced-by-count":2,"title":["STRUCTURAL CHANGES AND SEEMINGLY UNIDENTIFIED STRUCTURAL EQUATIONS"],"prefix":"10.1017","volume":"18","author":[{"given":"In","family":"Choi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2002,5,15]]},"container-title":["Econometric Theory"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0266466602183095","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,4]],"date-time":"2019-04-04T19:50:51Z","timestamp":1554407451000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0266466602183095\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,5,15]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2002,6]]}},"alternative-id":["S0266466602183095"],"URL":"https:\/\/doi.org\/10.1017\/s0266466602183095","relation":{},"ISSN":["0266-4666","1469-4360"],"issn-type":[{"value":"0266-4666","type":"print"},{"value":"1469-4360","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,5,15]]}}}
