“…Its canonical setting is the so-called core-periphery model introduced by Krugman (1991), showing the link between agglomeration and economic integration, and an early analytically solvable version with exogenous size asymmetries or asymmetric trade costs is provided by Forslid and Ottaviano (2003). In particular, we are close to those papers embedding the core-periphery model in an endogenous growth framework; see for example, Martin and Ottaviano (1999), Baldwin and Forslid (2000), Baldwin et al (2001), and Fujita and Thisse (2003) for some seminal contributions and Bond-Smith and McCann (2014) for a literature review. 2 Among the numerous subsequent core-periphery growth models, we share with Bond-Smith and McCann (2020) a focus on innovation, the presence of multiple sectors, and footloose skilled workers (i.e., freely choosing location in response to wage pressure).…”
