A pilot eﬀort was undertaken to experiment with a method of collecting parallel time series data for expectations and popular models and theories of institutional stock market participants in the United States and Japan 1989-91, covering the period before and after the dramatic and sudden halving of Japanese stock prices. Substantial variability within countries through time in the responses and dramatic diﬀerences across countries in expectations (even expectations for the same country) were found. There are signiﬁcant research opportunities in expanded data collection along these lines.
