We study the underlying structure of the two-dimensional dynamical system generated by a class of dynamic optimization models, which allow for intertemporal complementarily between adjacent periods, but which preserve the time additively separable framework of Ramsey models. Specifically, we...

This paper builds coordination costs, transaction costs, and other aspects of the theory of the firm into a production chain model with an infinite number of ex ante identical producers. The equilibrium determines prices, allocations of productive tasks across firms, firm sizes, and the number...
