Our paper uses simulation methods to examine the size and power of regime-switching tests for bubbles. We find that even with several hundred observations, the tests show sometimes considerable size distortion. This distortion makes the tests conservative; they understate the significance of the...

Summary Models which are built on the assumption of rational expectations can easily outline the conditions under which bubbles may exist but they remain silent on the factors that cause the price to deviate from the fundamental value. In this paper it is argued that dynamic extensions of the...

This paper develops a simple model to study the impact of stock markets on the current account. The model allows for an arbitrary number of risky assets, which form an incomplete market, as well as a risk-free bond. A closed-form solution for the current account is derived from the optimal...
