In terms of social networks, split graphs correspond to the variety of interpersonal and intergroup relations. In this paper we analyse the interaction between the cliques (socially strong and trusty groups) and the independent sets (fragmented and non-connected groups of people) as the basic...

This study presents a multispecies stochastic model. The model suggests optimal fishing policy for two species in a three species predator prey ecosystem in the Barents Sea. We have employed stochastic dynamic programing to solve a three dimensional model, where catch is optimized by a...

The analysis of social reasoning is at the core of understanding how to manage social networks. Since interpersonal relations are composed of multiple factors with different nature (i.e., structural and social factors), we explore their influence on the strategizing processes in social networks....

The new Basel III regulations are likely to make long-term financing more expensive, which will affect the financing of capital-intensive renewable energy technologies, because they typically rely on long-term financing. In addition, the capital and liquidity requirements of Basel III are likely...

Studies have shown that many consumers and businesses fail to invest in energy efficiency improvements despite seemingly ample financial incentives to do so – the so-called energy efficiency gap. Attempts to explain this gap often focus on searching costs, information frictions and behavioral...

Road tolls are a well established way of dealing with problems of congestion. Over recent years, the literature has expanded to take account of how congestion charges might interact with imperfections in other markets. In this paper, we consider the case where congestion occurs within a complex...

The returns to R&D literature is large and has been surveyed on several occasions. We complement previous surveys by using formal meta analytic techniques to analyse publication bias. We find evidence consistent with a strong positive bias in the part of the literature that controls for...

In this paper we propose a new spatial equilibrium model, and use it to discuss issues related to rural depopulation. The discussion focuses on how investments in transport infrastructure and the spatial distribution of basic sector jobs can promote a relatively balanced growth of peripheral and...

One may misread economic theory on climate policy to provide a warning against unilateral mitigation. While important lessons are drawn from ‘global problems require global solutions,’ these say little about what to do in a phase before or without a global agreement - or with weak ones. In...

Maritime bunker management (MBM) controls the procurement and consumption of the fuels used on board and therefore manages one of the most important cost drivers in the shipping industry. At the operational level, a shipping company needs to manage its fuel consumption by making optimal routing...
