International Management Strategies for a Straddling Fish Stock: A Bio-Economic Simulation Model of the Norwegian Spring-Spawning Herring Fishery

In this paper, a three-country dynamic bio-economic simulation model is presented for the spring-spawning herring fishery. The international spring-spawning herring fishery, based on potentially one of the most valuable fish stocks in the world, is currently recovering from a severe depletion of the stock and subsequent harvesting moratorium. Management of the herring fishery is complicated by its multi-nation exploitation, due to the highly migratory behaviour of the species moving between several coastal state zones (exclusive economic zones, EEZs) and the high seas (Ocean Loop). Based on extensive work invested on analysing both the biology of the herring stock and the fisheries economics around its exploitation we study here the profiles of different multi-agent management schemes, simulating catch levels, stock size and profit potentials of alternative management strategies. The stock dynamics are described by a linear discrete-time age-structured population model and the economics are presented by a rent maximising model with constant price of herring catch and different costs of harvesting and efficiency levels for the different national fleets. The simulations, carried out over several decades, show that the benefits of international co-operation far exceed the returns of a competitive open access fishery.JEL Classifications: C7, C15, Q22     

Distorted Performance Measures and Dynamic Incentives

Incentive contracts must typically be based on performance measures that do not exactly match the agents' true contribution to the principals' objectives. Such misalignment may pose difficulties for effective incentive design. We analyze the extent to which implicit dynamic incentives, such as career concerns and ratchet effects, alleviate or aggfravate these problems. Our analysis demonstrates that the interplay between distorted performance measures and implicit incentives implies that career and ratchet effects have real effects in that stronger ratchet effects or greater distortion may increase optimal monetary incentives, and that distortion affects the optimality of different promotion rules.     

The Performance Impact of Informal and Formal Institutional Differences in Cross-Border Alliances

This study addresses the simultaneous and diverse effects of differences in informal and formal institutions on cross-border alliances’ financial performance. We utilize data from 405 microfinance institutions (MFIs), based in 74 developing countries, that have alliances with partners from developed countries. We find that the impact of informal institutional differences between MFIs and their cross-border partners is sigmoid-shaped, with performance first increasing, then declining, before improving again as informal institutional differences grow large. By contrast, formal institutional differences appear to be detrimental to MFIs’ performance. Consistent with our prediction, we find that MFIs’ cross-border experience moderates both formal and informal institutional effects.     

Niche Firms and Partnerships in International Food Supply Chains

This study applies the partnership model to explore how internationally oriented niche firms organize and develop partnerships with their supply chain members, and how these niche firms are benefiting from these partnerships. This exploratory study uses semistructured in-depth interviews of key informants in four supply chains to obtain qualitative data.

The findings include observations of the drivers, facilitators, components, and outcomes of niche partnerships in supply chains. The results suggest that niche firms are able to overcome some of the weaknesses, without losing the advantages of being small, by forming channel partnerships.     

Intergenerational Effects of Guaranteed Pension Contracts

In this paper we show that there exist intergenerational cross-subsidization effects in guaranteed interest rate life and pension contracts as the different generations partially share the same reserves. Early generations build up bonus reserves, which are left with the company at expiry of the contract. These bonus reserves function partly as a subsidy of later generations, such that the latter earn a risk-adjusted return above the risk-free rate. Furthermore, we show that this subsidy may be large enough to explain why late generations buy guaranteed interest rate products, which otherwise would not have been part of the optimal portfolio allocation.     

Traffic risk perception,road safety attitudes,and behaviors among road users: a comparison of Turkey and Norway

The present study aims to investigate differences in road safety attitudes, driver behavior, and traffic risk perception between Turkey and Norway. A questionnaire survey was conducted among a sample of Norwegian (n?=?247) and Turkish (n?=?213) road users. The results show that Turkish respondents perceived traffic risk to be higher than Norwegian respondents. Turkish respondents reported safer attitudes towards drinking and driving than Norwegian respondents, while Norwegians reported safer attitudes towards speeding. Turkish respondents reported a lower frequency of speeding behaviors than Norwegian respondents, whereas Norwegian respondents reported a lower frequency of drinking and driving. Traffic risk perception was related to road safety attitudes and behaviors among Norwegian respondents but not among Turkish respondents. The results were discussed with respect to differences in traffic safety, traffic culture, and the development levels in Turkey and Norway.     

Participatory safety barrier analysis: a case from the offshore maritime industry

This paper argues that a participatory approach directly involving employees in safety barrier analysis can provide ‘added value’ to traditional barrier analyses. Employee participation (EP) could motivate employees to use their knowledge, suggest improvement measures and express their concerns. EP has not received much attention from safety researchers, although one may find several indirect arguments for EP informing the influential safety theoretical perspectives. An example of how participatory safety barrier analysis can be completed and what can be accomplished through such an approach is illustrated via a case study from an offshore logistics chain, and by an analysis of barriers that should prevent collisions between supply vessels and offshore installations. Such collisions could be the initiating event for a major accident. The empirical foundation for the paper is a hazard identification technique session, group and individual interviews, document studies and two search conferences involving approximately 150 participants. It is argued that a participatory approach to safety barrier analysis can reveal ‘holes’ in the defences that otherwise could have gone overlooked, and contribute to the generation of contextualized, definite measures that could strengthen a safety barrier system.
