Four Essays in Natural Resource Economics
On Thursday February 9 2023 Rasmus Noss Bang will hold a trial lecture on a prescribed topic and defend his thesis for the PhD degree at NHH.
TITLE OF THE THESIS:
Four Essays in Natural Resource Economics: Dynamic Modeling of Renewable and Nonrenewable Marine Resources
The thesis contains four papers on the economics of marine natural resources. The two first papers deal with fisheries, while the latter two deal with deep-sea minerals.
The first paper presents a single-species fishery model and analysis. The analysis shows that assumptions of constant natural mortality and weight can lead to significant overestimation of biological and economic potential of long-lived cannibalistic fish. The results further indicate that the North-East Arctic cod fishery can achieve higher sustainable and economic yield by changing the fleet composition and harvest control rule.
The second paper presents a predator-prey fishery model and analysis. The analysis shows that preferred selectivity and optimal harvesting change with the levels of predation and predation-weight conversion rates. Among other things, the results show that positive scaling of age-specific predation coefficients can shift the preferred selectivity towards smaller predator individuals and increase the optimal fishing pressure on the predator stock.
The third paper pinpoints three current factors that can play important roles in a possible transition to deep-sea mining, namely reserve-dependent capital efficiency, cross-sector competition, and mineral security considerations. By use of an optimization model, it is shown that all three factors can, in different ways, drive a transition to deep-sea mining. Possible counter effective factors are highlighted and discussed.
The final paper presents a stochastic dynamic simulation model for exploration and extraction of seafloor massive sulfide deposits on the Norwegian continental shelf. The model is developed based on a group model building session and disconfirmatory expert interviews. The model maps the sketched-out processes of exploration and extraction. Further, it is used to simulate the expected resource and economic potential of the emerging industry.
