2. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Introduction: EU policy framework Main issues at stake in EU fisheries: - stocks’ overexploitation and - socio-economic sustainability Management plans institution - Reg. No. 104/2000, 2371/02, 1198/06; 1967/06 (Mediterranean sea) – as a means to move towards a long-term perspective on fisheries management, to consider regional differences and to increase stakeholder involvement

3. 3 Introduction: the Northern Adriatic Strategic Agenda The Italian Regions of Emilia-Romagna, Friuli Venezia Giulia and Veneto have established a collaborative relationship with the other coastal communities of the Northern Adriatic Sea, For the implementation of shared common policies for the coordinated management of common resources in order to promote sustainable development in the Northern Adriatic fisheries sector. Institutional agreements and common program document called “Strategic Agenda for Sustainable Development of the Northern Adriatic ichthyic sector”.

4. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Providing empirical insights on the relevant geographical scale of the market for the most important pelagic fish species: - European Anchovy - Engraulis encrasicolus - Sardine - Sardina pilchardus Objective of the study Veneto and Emilia Romagna Pelagic pair trawlers

5. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Anchovies and Sardines are the two most important fish species and the first and third seafood products in Italy Emilia Romagna and Veneto account for a large share of national catches (tons) Supply chain description: catches

6. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Supply chain description: supply balance relevant exposure to international trade main trade partners: import – Croatia (86% anchovies, 55% sardines) export – Spain (90% anchovies, 60% sardines)

7. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Supply chain description: supply balance catches allow to attain self sufficiency (especially anchovies) higher internal availability for anchovies largely demanded by national processing industry (main species together with yellowfin tuna)

8. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland About 70 markets scattered along the coast 6 in Emilia Romagna and 6 in Veneto the study considers 4 markets in Emilia-Romagna and 1 in Veneto that account for almost 100% of pelagic species market transactions share of market transactions on landings (ER+VE): anchovies - 37% sardines - 77% important role of markets in price formation (auctions) –> benchmark for other transactions Supply chain description: markets

9. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland data consist of 5 years monthly time series of price and quantity for: 5 ex-vessel markets transactions (Orei) import and export (Eurostat) national catches and price (Irepa) preliminary descriptive analysis of data: market observations variability Principal Component Analysis (PCA) empirical regression model Data and methodology

10. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Variability is higher for quantity rather than for price Variability is higher for sardines than for anchovies, both for quantity and price Observations suggest a negative relation between price and quantity Descriptive analysis: price-quantity relation

12. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland The market is the area within which price is determined (Marshall 1961, Stigler and Sherwin 1985). If there is a single price over a given area, than must mean that either buyers or sellers (or both) consider transaction at any point within the area to be an excellent substitute for transactions at other points within the area (Stigler and Sherwin 1985). The concept of market integration is not clearly defined, and often based more on statistical criteria than on economic phenomena (McNew 1996) Market definition and market integration

13. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland On seafood ex-vessel markets, production quantity is not greatly affected by the prices, since the supply is closely connected to exogenous factors such as: biological cycles, the weather, and fishing regulations. Supply is exogenously determined and price represents the dependent variable. It is therefore correct to apply an inverse demand model: p i = f(m,q i,q j ) Price formation on ex-vessel markets

14. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland Normally, empirical investigations do not consider the influence of product availability at different geographical levels to analyse price-quantity relationships. BUT, if two quantity time series are strongly correlated (such as local and national production) an inappropriate price-quantity relationship could result statistically significant even without any real economic relation. Price-quantity relation and market geographical scale

15. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland The purpose of the empirical model is therefore to calculate price flexibility in the ex-vessel markets of the Emilia Romagna and Veneto Regions, affected by changes in local production (quantity landed and sold in each port) and national production. To quantify the price-quantity relationship a double logarithmic inverse demand system is used, where the product price on a market is a function of both the local catches and the larger market’s catches (Nielsen, 2005) Other determinants of price will be tested in addition at the basic model, such as income, cross effects between species, imports, trends and seasonal dummies.

19. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland The results of the empirical assessment conducted showed: a negative relation between price and quantity of the pelagic species considered price flexibility coefficients are smaller than 1, according to most literature results a statistical significance of both national and local quantity, varying across to the species and markets considered Conclusions

20. EAFE Workshop: “Optimising Value Chains in Fisheries” 1-2 June 2010 - University of Helsinki, Finland When empirical models do not consider the different geographical levels of markets, estimation results can be statistically significant without explaining the relevant economic phenomena  even for some of these markets we cannot exclude that the most appropriate level of integration is neither the local nor the national, but some sort of intermediate regional level. If policy intervention is targeted on price and income, the governance system (i.e. management plans) should consider the actual level of market integration  where markets are integrated at different geographical levels a pure local management would prove ineffective, requiring at least some common coordination among all the areas within the market boundaries.
