“…Several studies of trade liberalisation in renewable resources [6,8,9,[16][17][18][19][20] and of removing fisheries subsidies [10], departs from open access or optimal management. Analyses of such subjects needs necessarily to take into account that management are between the extremes, provided that results should be used as a realistic indicator for fisheries worldwide.…”

“…Clark elaborates further on the theoretical deduction of the supply curve [7]. Schulz use the backward-bending supply curve in a partial equilibrium set-up and discuss the relationship between long run stocks of marine mammals and trade policy [8,9]. Stone study the link between fisheries subsidies using a theoretical bioeconomic model [10].…”

Marine Policy, 33(1), 1-7. https://doi.Abstract. Recent research has on the basis of general equilibrium models warned that trade liberalisation in non-optimally managed renewable resources might cause overexploitation and reduced steady-state welfare. Welfare effects of trade liberalisation in open access and optimal management are found case specific and dependent on factors such as the country's status as importer or exporter, the state of the fish stocks and the size of the countries on the world market. The present paper develops an alternative partial equilibrium framework capable of identifying welfare effects of fish trade liberalisation also in the presence of complex but realistic management schemes, such as regulated open access and regulated restricted access. The case dependency known from the general equilibrium analysis is confirmed, but the introduction of realistic fisheries management schemes in the partial equilibrium model extended this case dependency. The welfare effect of trade liberalisation in an exporter country is negative under open access, but was found positive under regulated restricted access in the present paper.

“…160-1) conclude that "ambiguous stock effects make trade interventions a poor policy instrument for securing biodiversity conservation." Schulz (1997) shows that the effects of trade sanctions depend not only on the bioeconomic interactions between the species but also on the management system in the targeted country. Consequently, the threat of trade sanctions will not necessarily result in lower harvesting and higher stocks of marine mammals.…”

A Stackelberg Game Model of Trade in Renewable Resources with Competitive Sellers*

We model international trade in renewable resources between a single buyer and competitive sellers as a Stackelberg differential game. The buyer uses unit and ad valorem tariffs to indirectly encourage conservation of the renewable resource under study. First, we show that the efficacy of these trade policy instruments in promoting conservation depends fundamentally on whether harvesting costs are stock dependent or independent. When harvesting costs are stock independent, the optimal open-loop tariffs are dynamically consistent. In contrast, when harvesting costs are stock dependent, the optimal open-loop tariffs are dynamically inconsistent. Secondly, we point out that whether the terminal value of the resource stock is higher with the stock independent or the stock dependent cost function cannot be resolved unambiguously. Thirdly, we show that it does not make sense for the buyer to use both tariffs simultaneously. Finally, we discuss the implications of these and other findings for renewable resource conservation in general. . We thank an anonymous referee for helpful comments on a previous version of this paper. Batabyal acknowledges financial support from the Gosnell endowment at RIT. The usual disclaimer applies.
