URIBE, Jorge  and  FERNANDEZ, Julián. Financial bubbles and recent behaviour of the Latin American stock markets. Lect. Econ. [online]. 2014, n.81, pp.57-90. ISSN 0120-2596.

To contrast recent hypotheses in the economic literature stating that the formation of periodic and synchronized bubbles in global markets is a consequence of portfolio asset migrations, the financial bubbles of the Latin American stock markets with the biggest relative market size are estimated in this paper. Also, the chronology of the bubbles is compared to the one estimated for the United States. The bubbles are estimated using a sign test based on recursive median adjustment, which is used to test the null hypothesis of a random walk against the alternative of explosive processes. Empirical evidence is found that confirms the original hypothesis and allows exploring possible expansions thereof.

Keywords : Speculative bubbles; random walk; sign test; Latin American and US stock markets.
