Treatment of Mobile Phone Licenses in the National Accounts

This paper addresses the question of how to record mobile phone license payments in the national accounts. It concludes that there are usually two assets involved with mobile phone licenses: the spectrum, which is owned by the government, and the license, which is an intangible nonproduced asset sold by the government to the licenseholder. The values of these two assets are linked complementarily. A set of indicators is proposed that jointly may help judging whether the license or lease arrangement constitutes an asset in its own right or not. Alternative treatments of recording the license payments such as sale of the spectrum itself, other taxes on production, production of a service, or rent, are considered and rejected. Methods of amortization of the license over its life are considered.     

Optimal Management Under Institutional Constraints: Determining a Total Allowable Catch for Different Fleet Segments in the Northeast Arctic Cod Fishery

Many real world fisheries have an individual vessel quota system with restrictions on transferability of quota or entrance of new vessels into the fishery. While the standard economic reasoning is that these institutional constraints lead to welfare losses, the size of those losses and optimal second-best policies are usually unknown. We develop a dynamic bioeconomic model, in which a scientific body provides an optimal TAC given restrictions on (i) transferability between vessel segments and (ii) entrance of new vessels. Further, we also quantify welfare losses arising from not maximizing economic welfare, but physical yield—which is actually the case in many fisheries. We apply the model to the Northeast Arctic cod fishery, and estimate not only the cost and harvesting functions of the various vessel types, but also the parameters of the biological model as well as those of the demand function. This allows us to determine optimal second-best policies and quantify corresponding welfare effects for our case study fishery.     

The relationship between the firm's social media strategy and the consumers' engagement behavior in aviation

Social media platforms constitute a new frontline for brands to build relationships with their customers. Nevertheless, the literature on social media engagement behavior is unidimensional, as it focuses on customer engagement while neglecting the customer's influence on managerial decisions. The current paper goes a step further by applying the theory of the marketing firm (TMF). We investigated consumer-firm bilateral contingencies through three studies. The first study captures up to 60% of the variance in consumer responses given on Icelandair's Facebook page. The second study shows how customers engage with Icelandair's social media platforms. The third study illustrates the firm's social media strategy from a managerial perspective.
