We consider a model of international trade with increasing returns in a non-traded input into industry, “infrastructure”, and show that the nature of equilibrium depends crucially on whether the infrastructure provider acts in a “naïve” manner – akin to a Level 1 agent in a cognitive...

We model an economy with two final goods, manufactures produced under IRS and food. The scale economies in manufacturing are external (therefore compatible with perfect competition) and traceable to internal economies in the provision of an infrastructural service (the third sector of the...

We consider a model of international trade with increasing returns in a non-traded input into industry, infrastructure, and show that the nature of equilibrium depends crucially on whether the infrastructure provider acts in a nave manner akin to a Level 1 agent in a cognitive hierarchy (C-H)...

Multiple Pareto-rankable equilibria may obtain in an overlapping generations model where consumers save to reach a fixed target. Existence and uniqueness conditions are discussed. The model displays excess consumption sensitivity to current income and perfect old-age insurance.
