Constant Returns to Scale: Can the Neoclassical Economy Exist?

Alam, M. Shahid - Volkswirtschaftliche Fakultät, … - 2013

Constant returns to scale (CRS) is one of the corner-stones of the competitive general equilibrium paradigm of neoclassical economics. This note argues that the equilibrium solutions of this paradigm are not compatible with CRS. CRS implies that all producers (whatever their scale of production)...

Uniqueness of Markov equilibrium in stochastic OLG models with nonclassical production

Hillebrand, Marten - In: Economics Letters 123 (2014) 2, pp. 171-176

A large class of stochastic OLG economies with nonclassical production is shown to possess a unique Markov Equilibrium (ME) which is also the unique sequential equilibrium. Additional properties such as monotonicity, continuity, and smoothness of the ME are also discussed.
