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

Seasonal Harvest Patterns in Multispecies Fisheries

Fishers face multidimensional decisions: when to fish, what species to target, and how much gear to deploy. Most bioeconomic models assume single-species fisheries with perfectly elastic demand and focus on inter-seasonal dynamics. In real-world fisheries, vessels hold quotas for multiple species with heterogeneous biological and/or market conditions that vary intra-seasonally. We analyze within-season behavior in multispecies fisheries with individual fishing quotas, accounting for stock aggregations, capacity constraints, and downward-sloping demand. Numerical results demonstrate variation in harvest patterns. We specifically find: (1) harvests for species with downward-sloping demand tend to spread out; (2) spreading harvest of a high-value species can cause lower-value species to be harvested earlier in the season; and (3) harvest can be unresponsive or even respond negatively to biological aggregation when fishers balance incentives in multispecies settings. We test these using panel data from the Norwegian multispecies groundfish fishery and find evidence for all three. We extend the numerical model to account for transitions to management with individual fishing quotas in multispecies fisheries. We show that, under some circumstances, fishing seasons could contract or spread out
