Indeterminacy Arising in Multi-Sector Economies
We characterize a large class of constant-returns-to-scale economies with standard Cobb-Douglas production technologies, which, when perturbed to incorporate external effects, exhibit indeterminacy or multiple...

Transboundary Pollution in a Dynamic Game Model
We consider a dynamic game model in which N countries produce a single product that is not traded. Production results in emissions that accumulate a stock of pollution in each country. Households in each country ...

Interior Optimal Chaos with Arbitrarily Low Discount Rates
In this study, we demonstrate, for an arbitrarily small discount rate, the existence of a topologically chaotic policy function that lies in the interior of the technology set in a two-sector model with smooth...

Optimal chaos, nonlinearity and feasibility conditions
This study constructs a class of dynamic models in which optimal paths are generated by nonlinear transition functions similar to a tent map. We provide a sufficient condition under which such a transition fun...

Ergodic chaos in optimal growth models with low discount rates
We show that for every discount factorρε(0,1) one can find infinitely many strictly concave discrete-time optimal growth models in reduced form which have optimal policy functions exhibiting ergodic chaos. These ...

Interlinkage in the endogenous real business cycles of international economies
This study investigates interlinkage among the business cycles of countries from the viewpoint of endogenous real business cycles. For this purpose, we build a simple perfect foresight equilibrium model with t...
