The purpose of this paper is to gain a better understanding of the black market premium--the percentage differential between the black market and the official exchange rate. Tests are used to see whether the black market premium responds to variations in expectations about the official exchange rate in Argentina, Brazil, Colombia, and Mexico. Expectations of devaluation do cause movements in the black market premium for Argentina, Brazil, and Mexico but this behavior is not observed for Colombia. Colombian economic agents seem less sensitive to expected returns. This perhaps explains the relatively flat black market premium series observed for Colombia.
