Perish or prosper: Trade patterns for highly perishable seafood products

In recent years trade with highly perishable agricultural products like fresh fish, berries, and cut flowers has increased substantially. The perishability of these products appears to challenge conventional wisdom when it comes to food trade, which emphasizes the importance of large shipments to reduce transportation costs. In this paper, gravity models and several margins of trade are estimated for the trade with fresh salmon, a highly perishable product. The results indicate that increased geographical distance have a larger negative effect than what is generally reported in the literature. Most interestingly, the number of exporters and the shipment frequency increase while there is little impact on shipment size when trade increase. Hence, freshness and possibly avoidance of losses by not selling products by the expiration date seem to be emphasized rather than economies of scale in transportation.

Estimating Pricing Rigidities in Bilateral Transactions Markets

Many price indices are constructed using bilateral transaction prices. This paper shows how the time series behavior of cross-sectional price moments can reveal useful information about pricing behavior in bilateral transactions markets. Inference is formalized in a microlevel price determination model that allows for rigid pricing at the level of individual buyer/seller transactions as well as asymmetries in bargaining power. The model is used to estimate pricing rigidities in Norwegian salmon export transactions. Results suggest a high rate of price revisions and an informative salmon price index. The moments suggest price revisions are conducted at fixed time intervals consistent with optimal price revisions under costly information and that price revisions are more likely when transaction prices are below the reference price in the market.publishedVersio

Tools of the trade: trade flexibility with respect to margins and buyers

Access to highly disaggregated trade data allows for a more nuanced investigation of different margins of trade, and the factors known to influence them. In this paper, the number of importers and shipments to each importer is investigated together with the more traditional margins. Potential explanatory factors of these trade margins are combined from three literature strands in addition to the standard gravity variables; firm productivity, per-unit shipment costs and country-specific trade costs. The empirical results show, not unexpectedly, that insights from all these different strands of literature influence trade margins significantly. In particular, the number of shipments per importer increases with distance, degree of remoteness and per-shipment cost, and the number of importers decreases with the distance, remoteness and per-unit shipping cost. This indicates that increased trade costs make exporters economize in existing networks. Finally, disaggregating the data into three main product categories using Rauch’s classification, trade patterns are shown to vary by product group.publishedVersio

Dynamics of Buyer-Seller Relations in Norwegian Wine Imports

As for all traded products, aggregated wine imports build on numerous trades at the firm level. To ensure consumers access to a variety of wines with different qualities, importers need to connect to different wine exporters. Some of these relationships will last for a long time, while the duration of others may be short. In this article, we employ transaction-level data to analyze the duration of trade relationships in wine imports to Norway from 2004 to 2014. We find that most relationships are short-lived, as more than 75% of trade relationships end after less than two years. Furthermore, we find that higher-quality wines, as indicated by the import price, increase trade duration. Deeper firm-to-firm trade relationships for more exclusive wines are likely due to higher search costs for high-quality products. The results also show that the size of the initial trade between the partners, or degree of commitment, is a positive determinant for persistent relationships.

Delivering the Goods: The Determinants of Norwegian Seafood Exports

Seafood is the world’s most traded food product. In recent years, aquaculture has become an increasingly important part of seafood production, facilitating increased trade. However, despite evidence that fish farmers have better ability to target markets and ship their seafood through more efficient supply chains (due to the higher degree of control with the production process), little attention has been given to the fact that this is likely to influence trade patterns as well. This article investigates if trade margins for aquaculture products differ from trade in wild seafood products along three margins of trade, in addition to total export value on export data for Norway, the world’s second largest seafood exporting country. The results indicate aquaculture products are different. In particular, aquaculture products are influenced by more factors than fisheries products (such as transportation costs and per-unit shipment costs), highlighting another dimension where the control of the production process can be used to improve competitiveness. Moreover, exports of aquaculture products increase with a country’s wealth level, reflecting producers’ ability to target higher paying markets.acceptedVersio

Is capture-based aquaculture viable? The case of Atlantic cod in Norway

Capture-based aquaculture (CBA) is an important branch of the aquaculture industry that differs from closed cycle farming in that the stocking material consists of captured wild fish or other aquatic organisms. By skipping the difficult early production stages of fish farming, producers can test whether assumed market advantages such as high quality and consistent supply result in higher prices – and whether these are high enough to incentivize further development of CBA and eventually close the production cycle. CBA-initiatives can also be supported by different policy measures to stimulate the activity. Since these measures involve costs, it is important to know at what level and for how long these measures should be implemented to promote economically sustainable CBA activities. We study CBA of Atlantic cod (Gadus morhua) in Norway and find an average price premium of 26% compared to wild harvested cod, but with large interannual variation. However, declining quantities of cod from CBA following reductions in a quota bonus scheme to stimulate activity, indicates that the price premium is not sufficiently large to incentivize further development of the CBA branch of the Norwegian cod industry

Production growth, company size, and concentration: The case of salmon

The largest companies in salmon aquaculture are rapidly getting bigger due to organic growth as well as mergers and acquisitions, and the largest are now multi-national companies. There are two main explanations for this growth: 1) An attempt to become large enough to exploit market power, or 2) Size is necessary to adopt new technologies that increase the efficient scale. In this paper, we investigate the degree of concentration in each of the main producer countries for Atlantic salmon, as well as globally for Atlantic salmon, all farmed salmon, and all salmon to account for the global nature of the market using Herfindahl-Hirschman Indexes. The results indicate a high degree of concentration in the smaller producer nations but not in Chile and Norway. Globally, the Atlantic salmon industry can be characterized as unconcentrated, and it becomes even more so when the supply of other farmed salmon and wild salmon is accounted for. Hence, the main motivation for the increased company size appears to be capacity to adopt new knowledge and technology.publishedVersio

Impacts of Covid-19 on Norwegian salmon exports: A firm-level analysis

A rapidly growing literature investigates how the recent Covid-19 pandemic has affected international seafood trade along multiple dimensions, creating opportunities as well as challenges. This suggests that many of the impacts of the Covid measures are subtle and require disaggregated data to allow the impacts in different supply chains to be teased out. In aggregate, Norwegian salmon exports have not been significantly impacted by Covid-related measures. Using firm-level data to all export destinations to examine the effects of lockdowns in different destination countries in 2020, we show that the Covid-related lockdown measures significantly impacted trade patterns for four product forms of salmon. The results also illustrate how the Covid measures create opportunities, as increased stringency of the measures increased trade for two of the product forms. We also find significant differences among firms' responses, with large firms with larger trade networks reacting more strongly to the Covid measures. The limited overall impacts and the significant dynamics at the firm level clearly show the resiliency of the salmon supply chains.publishedVersio

Challenges and opportunities: impacts of COVID-19 on Norwegian seafood exports

A rapidly growing literature shows that COVID-19 and the measures to contain the spread of the virus can have significant market impacts for seafood. These can be interruptions of production, or reductions in demand directly or indirectly due to supply chain challenges. In this paper we investigate the potential impacts of COVID-19 on seafood exports from Norway, the world's second largest seafood exporter, using highly detailed data from 2016 through May 2021. These data allow us to assess upstream impacts in the seafood supply chain close to the producer level in aggregate and by main sector, impacts on the largest products, and the extent to which export firm structure and export markets served have changed. We find very few impacts in aggregate as well as for individual products, suggesting that the markets and supply chains used by Norwegian seafood exports were sufficiently robust and flexible to accommodate the shocks created by COVID-19. Given Norway's size as a seafood exporter, the impact of COVID-19 has likely been moderate upstreams for a number of seafood sectors around the world, especially those in wealthy nations, with opportunities balancing out challenges, and that the supply chains have been highly resilient.publishedVersio
