i'd be interested in seeing the stuff on K-waves, only because i have heard the expression, but don't know what they are. have you seen something on the net about it? otherwise, can you mail me a xerox of one of his papers? (i am not near a good library right now)

pre-novice question: are these waves derived from economics models which predict oscillatory pheonomena, or are they simply a Fourier transform of data with some 'big' peaks in it??? if the latter, how long are the time records relative to the periodicty of the wave?
couple years ago i had an astrophysics problem acting thusly: random walks with a 'restoring force' produced a wavy looking plot if observed over a couple 'auto-correlation' time scales (time for a fluctuation to disppear into the mean level)... if you watch the random walk over longer time periods, however, you don't see such a persistent periodicity so clearly... (its been a while, i have to look back at my results :-) )

lets see, a dumb 'toy' oscillator model:
production rate increases proportional to worker happiness
worker happiness decreases proportional to production rate
