This book provides an\nanalysis of the notion of (weak)          exogeneity, which is\nnecessary to sustain valid inference in sub-systems, inthe\nframework of error correction models (ECMs).\nIn many practical      situations, the applied econometrician\nwants to introduce \"structure\" on    his\/her model in order to\nget economically meaningful coefficients. For thispurpose,\nECMs in structural form provide an appealing                       framework,\nallowing the researcher to introduce                             (theoretically\nmotivated) identification restrictions on the long           run\nrelationships. In this case, the validity of the inference\nwill     depend on a number of conditions which are investigated\nhere. In particular,we point out that orthogonality tests,\noften used to test for weak          exogeneity or for general\nmisspecification, behave poorly in finite samples and are\noften not very useful in cointegrated systems.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1993-06-14\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783540566397\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-642-95706-2\u003c\/p\u003e \u003cp\u003eDimensions: 242cm x170cm\u003c\/p\u003e \u003cp\u003ePages: 189\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":44398516699276,"sku":"9783540566397","price":49.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783540566397.jpg?v=1774028645","url":"https:\/\/lateknightbooks.com\/products\/9783540566397","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
