Scenario Analysis for Arctic Marine Resource Policy
No full textFuture changes in Arctic marine ecosystems will depend as much on global climate change as on our ability to regulate and manage the exploitation pressure at sustainable levels. There is a lack of integrated, cross-sectoral ecosystem-based analysis of the Arctic marine management. The analysis would ideally include both the choices for implementing regulatory tools and how they will affect the many ecosystem-dependent values derived from them. The ability to maximize these values depends critically on the ways in which the dynamic bio-economic properties of the resources are impacted by the human behavior induced by the regulations (or lack thereof). In this paper it is speculated about likely changes in the future Arctic fisheries based on a scenario building approach. The underlying changes to ecosystems are the climate changes which is also one of the drivers and the likely impacts in the Arctic. Other drivers can be identified but by selecting two main drivers it is possible to map four scenarios to be further analyzed. The drivers are the sectoral development of important marine sectors (fishing, shipping, mining etc.) and governance structure development. The development in each of these driving force’s dimensions is uncertain and central in the analysis are risk and uncertainty. The results indicate that the future climate changes might involve relatively large changes in the ecosystem and hence fish stocks, but also that the economic outcome of fisheries depends critically upon our ability to adjust the regulatory regime to capture the values of the ecosystem services.</p
Ratcheting in Renewable Resources Contracting
Full text linkReal life implies that public procurement contracting of renewable resources results in repeated interaction between a principal and the agents. The present paper analyses ratchet effects in contracting of renewable resources and how the presence of a resource constraint alters the “standard” ratchet effect result. We use a linear reward scheme to influence the incentives of the agents. It is shown that for some renewable resources we might end up both with more or with less pooling in the first-period compared to a situation without a resource constraint. The reason is that the resource constraint implies a smaller performance de-pendent bonus, which reduces the first-period cost from concealing information but at the same time the resource constraint may also imply that second-period benefits from this concealment for the efficient agent are reduced. In situations with high likelihood of first-period pooling, the appropriateness of applying lin-ear incentive schemes can be questioned.Political support function, political economy, environmental regula-tion, lobbyism, rent-seeking, taxation, auction, grandfathering, emission trad-ing, European Union, interest groups, industry, consumers, environmentalists
Families versus Machines: On how a startup can improve digital well-being in the family life
No full textThe goal of this project was to find a way to improve digital well-being in family life through design for the startup Unpluq. In this thesis, the designer combined a design approach called Value Sensitive Design with the list of requirements methodology taught at Industrial Design Engineering. This resulted in a new methodology that allowed the designer to develop a concrete list of requirements and wishes for improving well-being through design. To establish this list of requirements, the design student performed a detailed literature review on positive psychology, behavioural economics and digital parenting literature. In addition to this, he interviewed both parents and children to empathise with their world views. Lastly, he performed a market analysis to understand how the context and available resources could affect Unpluq’s capacity to take up a role in this new market. Based on this research, the answer found is that improving digital well-being in the family life requires the design of a choice architecture that helps parents and children take more conscious control of their time and attention (both transactional values). Doing so should allow them to spend these transactional values on activities that align with things they intrinsically value. This choice architecture should help rearrange actors, artefacts, and stimuli within the family home environment so that time is less easily spent without intentional consent. Based on this list of requirements, the design student initiated a design process to translate these insights into a physical design concept that Unpluq could bring to the market to help families rearrange this choice architecture. This design process was executed by iteratively evaluating design concepts with both the client, potential end-users, experts, and professionals from different psychology and pedagogics fields. In the end, the designer delivered a concept that stimulates reflective thinking about what users find intrinsically valuable and provides tips, tools and challenges that push them to try and change habits. This is done by focusing on conversations that help raise awareness of the critical issues and stimulating the iterative goal setting that the family should engage in to start solving these issues for themselves. The way that time can and should be allocated for intrinsically valued activities was so unique for each individual and family that it is hard to find one solution to help everyone. Therefore, the core insight of this project for Unpluq is that if they would be interested in entering this market, their focus should be on helping families reimagine the way they use their environments within their own family homes. This should be done both individually and together through reflection and iteration and supported in that journey by scientific and expert information.https://unpluq.com/graduation-niels/ Presentation webpageStrategic Product Desig
Technical Efficiency of the Danish Trawl fleet: Are the Industrial Vessels Better than Others?
Full text linkTechnical efficiency in the Danish trawl fishery in the North Sea is estimated for 1997 and 1998 by a stochastic production frontier model. This model allows noise when the frontier and the technical efficiency is found, which for fisheries is a reasonable assumption. The results show that the production frontier can be modelled by a translog function without time effects and a technical ineffi-ciency function. The type of fishery (industrial or consumption), size of vessel (greater or lesser than 60 GRT) and year give a good explanation for the ineffi-ciency in the fleet. The average technical efficiency is estimated to be 0.82. On average, industrial vessels have a higher technical efficiency than human con-sumption vessels, and smaller vessels have higher technical efficiency than lar-ger vessels. In sum, the analysis reveals that vessel larger than 60 GRT and fishing industrial species are the most efficient.Technical efficiency, stochastic production frontier, Danish trawl fishery

DISCARD BEHAVIOR, HIGHGRADING AND REGULATION: THE CASE OF THE GREENLAND SHRIMP FISHERY
Full text linkA formal economic analysis of the discarding problem is presented, focusing on the individual fisherman and the effect of different regulations on the fisherman's incentives to discard. It is shown that in a nonregulated fishery, either multispecies or single species/multisize, where the only constraints are the hold capacity and the length of the season, the fisherman may have rational incentives to discard/highgrade, if the marginal trip profit of an extra fishing day is greater than the average trip profit. Regulation by TAC does not change the incentives to discard. However, under INTQs and ITOs, the incentives to discard increase. The incentives to discard decrease under ITQs compared to INTQs, if the unit quota price is smaller than the shadow price of the quota. The model is applied to the Greenland shrimp fishery, where it demonstrates the reported discard behavior in the fishery. Finally, different regulations of discard are applied and discussed in the model. The analysis suggests that regulation of fishing days could be a promising alternative to usual suggested measures like tax/subsidies and landings obligations.Resource /Energy Economics and Policy,
