      abstract = {Patterns in price adjustment in response to information  are important to market
practitioners. This study looks at  cowpea real wholesale price adjustment patterns  in
Bolgatanga, Wa, Makola and Techiman markets in Ghana.  Using Techiman as the central
market, a threshold  autoregressive test for asymmetric price adjustment  rejected the null
hypothesis of symmetric adjustment for  only the Bolgatanga-Techiman price series.  An
autoregressive conditional heteroskedastic regression  indicates that wholesalers in
Bolgatanga market respond  differentially to price signals from Techiman than those in  the
other two markets. This suggests that policies  targeting cowpea traders must recognize the
differential  responses by wholesalers to information.},
