Some recent research indicates that the occurrence of indeterminacy in mod- els with externalities may be overstated because these models ignore agents’ heterogene- ity. We consider a neoclassical two-sector growth model with technological externalities. Agents are heterogenous in respect to...

Dynamic economic models usually describe the path of economic variables as prices, consumption or capital at equilibrium. The most popular models assume that agents have perfect foresight. Implicitly this assumption requires that agents can compute the complete infinite path, an exercise that...
