Abstract: | This paper uses a threshold adjustment methodology to find out whether price
transmission over the cod value chain between Norway and Portugal is asymmetric. The basic
setting relies on price theory and the relationship between prices in the fish market. Empirical
tests of price transmission use a cointegration framework similar to many other non-stationary
time series analyses. However, it appears that testing for asymmetric price transmission has not
been done so often in the fish market, despite the recent availability of non-linear time series
techniques designed to this end. TAR and M-TAR adjustment models can be used in this
context. Our results show that while the three price series used in the cod value chain between
Norway and Portugal are cointegrated, there is no evidence of asymmetric price adjustment in
this market. |
