Derivation of econometric estimable functions of intra-trade industry: the case of the Norwegian intra-continental import trade pattern
Tesfay, Yohannes Yebabe; Solibakke, Per Bjarte (Journal article; Peer reviewed, 2017)This paper evaluates the item based Norwegian intra-continental trade pattern. The paper derives the best linear unbiased estimator (BLUE) of estimable functions of the two-stage non-full rank hierarchical linear econometric ... -
Intercontinental variations of the import trade pattern of Norway: applications to best linear unbiased estimable functions of hierarchical econometric model
Tesfay, Yohannes Yebabe; Solibakke, Per Bjarte (Journal article; Peer reviewed, 2017)This paper’s main purpose is an analysis of the intercontinental variations of Norwegian import expenditures based on yearly import data from 1988 to 2014. We estimate functions for the best linear unbiased estimator (BLUE) ... -
