| Sumario: | Abstract: Sustainability labelling-schemes for marine fisheries are taking a prominent position in the
supply chain governance of an increasingly globalised seafood market. These mechanisms can
stimulate commercial exchange if their adoption facilitates access to export destinations or they
can operate as non-tariff measures, reducing trade. It has recently been argued that the market
for certified sustainable seafood remains a Northern affair. This argument leads to the crucial
questions of who is benefiting from eco-labels and what is their impact on developing countries.
To the best of our knowledge, no econometric analysis on their performance as catalysts or
barriers to trade has yet been conducted.
Using a unique dataset that accounts for eighty percent of world seafood flows built specially
for this study and based on UN Monthly Comtrade (2010-2014), this research offers empirical
evidence of the effects of eco-labels on seafood trade. The estimation of a structural gravity
model at product level is augmented with the addition of an eco-label presence variable. This
variable is interpreted as a preference parameter, if the process of differentiation stimulates
trade flows, or as a trade cost, if trade flows decrease, thus acting as a non-tariff measure.
Results from the estimation of the Poisson pseudo-maximum likelihood multiplicative
estimator reveals that the effect of an eco-label is significant in statistical terms and positive for
every product. This result is the first available evidence that eco-labels operate as a catalyst of
seafood trade. |
