The Norwegian bottom-trawl fleet is managed through individual vessel quotas and is generally engaged in codfish fisheries, where several species contribute to the revenue of the fishery. The revenue from the fishing exhibits substantial intra-annual variation and carries a significant degree of risk due to the presence of intrinsic volatilities in the marine environment, such as seasonal fluctuations ...

Previous research suggests that consumers would listen more to product recommendations from other consumers (human recommenders) than from systems based on artificial intelligence (AI recommenders). We hypothesize that this might depend on the type of product being recommended, and propose an underlying process driving this effect. Three experiments show that, for hedonic products (but not for ...

Tourism seasonality negatively affects hotels’ operational and financial performance and then survival probabilities. Several studies have evaluated the impact of tourism seasonality on hotels’ exit risk. However, the empirical findings are ambiguous, probably due to the overall seasonality and different measures used in these studies. Against this background, this study explores the impact of tourism ...

It describes the historical background of the laws and regulations that are applicable in Norway and the conditions that must be met to achieve the participants' free and informed consent. Furthermore, it explains who should be informed and give consent and gives ...

In this article, we discuss the role of open innovation in collaborative design processes in mature industries such as the shipping industry. We examine the design of high-tech offshore service vessels in environments characterized by high volatility and complexity. We elaborate on the role that accumulating and sharing core competences plays in speeding up the innovation process and increasing ...

In fisheries, formal institutions are intentionally implemented to protect the stock of fish and to better adjust the fleet’s catch capacity to the resource base. The present study, however, explores how the same institutions also influence competitive forces that shape industry attractiveness and the profitability of fishing boats. The empirical context is a sample of Norwegian seagoing purse seiners ...

This paper reports on an experiment that investigates how inequality in advantage affects individual preferences for honesty and generosity. In a two-stage experiment, subjects first earn money according to self-reported production, which can include honest and dishonest reports. Subjects then play the dictator game and decide how much, if any, of their earnings to share with an anonymous recipient. ...

Purpose - The purpose of this research is to detect, through applying a process-based view, how to manage economisation of the maintenance and modification operations in offshore petroleum logistics operations.<p> <p>Design/methodology/approach - A single case study of engineering services, more specifically, maintenance and modification service operations, on a Norwegian Sea oil platform reveals ...

The literature on product variety provides great insights into various businesses. However, little research has been conducted on product variety in the healthcare industry. This study aims to explore the influence of product variety on inventory in hospitals. Since most hospitals are known to replenish products using a homegrown ad-hoc system, a model is developed for exploring all possible ...

Regional convergence studies have relied on net migration data in assessing the impact of migration. With heterogeneous labour, the implied symmetrical treatment of immigration and emigration cannot be justified a priori.. Because of heterogeneity among migrants, gross migration flows may lead to considerable interregional redistribution of human capital even when net migration is zero. Moreover, ...
