Globalization and financial development: A model of the Dot-Com and the Housing Bubbles

In the last decade the United States experienced the burst of the Dot-Corn and the Housing Bubbles. I develop a model to study the relationship between globalization and the emergence of rational bubbles. I also analyze how the effect of globalization on house prices depends on the type of bubble. I show that bubbles cannot arise in a financially developed country in autarky. In contrast, as globalization progresses, bubbles are more likely to appear in the financially developed country. I also show that house prices increase with globalization only when the bubble is attached to houses. This prediction is consistent with empirical evidence for U.S. metropolitan areas.
