| Abstract: | Russia is experiencing deep structural changes in many areas. For the seafood 
industry important developments are large increases in household incomes, 
development of modern super- and hypermarket distribution channels, and 
product innovations. In the seafood category consumers are adopting new 
species and new product forms at a rapid rate. Herring is one of the species 
that is experiencing these changes. The dominant product form has 
traditionally been whole salted herring, typically sold at open markets. 
Herring sold in the traditional unprocessed form has been a protein source for 
poor people, consumed at home. But more processed and expensive product forms 
that are distributed through modern distribution channels have increased their 
market share during the data period. <p> We employ a panel data set on monthly 
per capita demand for different herring products in six Russian regions, from 
unprocessed to value added products, to test hypotheses on the structure of 
herring consumption. We estimate dynamic panel data demand systems, with 
region-specific estimates of price and income elasticities. The six regions in 
the data set have large differences in average per capita income. Our 
econometric estimates indicate significant structural regional differences in 
per capita consumption of different products, also after controlling for 
income differences. We find that whole herring is generally an inferior good, 
whereas fillet herring products tend to be normal goods. This suggests that if 
incomes continue to increase, consumption will shift further from unprocessed 
to value added herring products. |
