This paper asks whether adjustment processes over real time help to "select" the long-run outcome in a model of industrialization, where multiple stationary states exist because of increasing returns in the manufacturing sector. "History" alone cannot in general determine where the economy will end up. Self-fulfilling expectations often make the escape from the state of preindustrialization (the takeoff) possible. The global bifurcation technique is used to determine when an underdevelopment trap exists and when a takeoff path exists. The role of government policy and agricultural productivity in industrialization are then considered.

This paper demonstrates that an optimizing model of a monetary economy can produce perfect foresight equilibria in which the price level fluctuates forever. Cyclically or chaotically fluctuating equilibria are more likely to exist when the rate of money supply growth is high. Furthermore, the set of equilibrium prices may have a complicated topological structure, which poses a more serious problem concerning the validity of comparative statics method than any sort of indeterminacy previously discussed in the literature.
