AbstractPrice transmission asymmetry for peanuts used in peanut butter was examined using monthly data from 1984 to 1992. Results show an incomplete price passthrough from the wholesale to the retail level. Furthermore, the results indicate that the initial price response of peanut butter price to a reduction in peanut prices occurs later than the response to an increase in peanut prices. The price transmission is asymmetric in the short‐run but symmetric in the long‐run. © 1995 by John Wiley&Sons,
