Bajo Rubio, ÓscarGómez Gómez-Plana, Antonio2016-05-102016-05-102000https://academica-e.unavarra.es/handle/2454/20557Empirical assessments of trade policy in single-country models have addressed extensively the assumption of increasing returns to scale versus constant returns to scale, but the alternative assumption of small open economy versus large open economy has not received much attention. This paper provides an evaluation of the relevance of both assumptions (i. e., returns to scale and country size) when analyzing a process of economic integration for a medium-size economy. We conclude that the often neglected country-size assumption might be more relevant for the empirical results than returns to scale.27 p.application/pdfengCC Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)Applied general equilibriumCountry sizeReturns to scaleTrade policyinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/openAccess
