We show that these two models differ starkly in terms of their implied predictions. The conditional logit model represents a zero-sum world, in which one region&#8217;s gain is the other regions&#8217; loss. In contrast, the Poisson model implies a positive-sum economy, in which one region&#8217;s gain is no other region&#8217;s loss. We also show that all intermediate cases can be represented as a nested logit model with a single outside option. The nested logit turns out to be a linear combination of the conditional logit and Poisson models. Conditional logit and Poisson elasticities mark the polar cases and can therefore serve as boundary values in applied research.<\/p>\n","protected":false},"author":1,"featured_media":0,"menu_order":0,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"tipologia_publicacion":[21],"programa_rel":[84,84,84],"class_list":["post-403657","publicacion","type-publicacion","status-publish","hentry","tipologia_publicacion-working-paper"],"acf":[],"_links":{"self":[{"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/publicacion\/403657","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/publicacion"}],"about":[{"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/types\/publicacion"}],"author":[{"embeddable":true,"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/publicacion\/403657\/revisions"}],"wp:attachment":[{"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/media?parent=403657"}],"wp:term":[{"taxonomy":"tipologia_publicacion","embeddable":true,"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/tipologia_publicacion?post=403657"},{"taxonomy":"programa_rel","embeddable":true,"href":"https:\/\/ieb.ub.edu\/en\/wp-json\/wp\/v2\/programa_rel?post=403657"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
