Using a fad model with Markov-switching heteroscedasticity in both the fundamental and fad components (UC-MS model), this paper examines the possibility that the 1987 stock market crash was an example of a short-lived fad. While we usually think of fads as speculative bubbles, what the UC-MS...

Estimates of the slope of the Phillips curve reported in the literature cover a range from roughly − 0.6 to zero depending on specification. Forward-looking specifications, favored by theory, produce the smallest slope estimates. This paper addresses this puzzle by studying the bivariate...
