Therefore,origin is one of the main factors that explain red shrimp price variations. This is in accordance with Asche and Guillen who found that origin was the most important explanatory factor for hake prices in the Barcelona's wholesale market.In the alternative model,the origin variability is partially
explained by the travel time between the portand Barcelona's
wholesale market.When travel time in creases by 1% the price of
red shrimps increases by 0.06 %.Therefore,the longer the travel
time from the wholesale market to the port area,the more difficult
it is to obtain luxury substitutes in the area,and so local prices are
higher.
