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.     

How to Steer the IT Outsourcing Provider

IT executives entering into information technology (IT) outsourcing arrangements seek various strategic, economic, and technological benefits. However, although several cases of IT outsourcing are considered successful, cases of failure can also be observed. Problems and challenges associated with IT outsourcing often not only relate to the strategic decision whether or not to outsource, but to the operational level as well. Especially organizations with little experience of implementing larger IT outsourcing programs face problems with the steering of external outsourcing providers. In this paper, we propose a reference framework that structures the required processes for an effective steering of IT outsourcing relationships. The research is based on the design science paradigm in information systems research. In a first step, we derive a framework from related literature and knowledge in this particular area. We then undertake extensive fieldwork, including expert interviews and field studies to evaluate our framework and to develop it further. The suggested framework proves to be a viable instrument to support the systematic analysis of current processes and the definition of suitable target processes for the steering of IT outsourcing programs. This paper??s primary contribution therefore lies in providing an applicable instrument for practitioners as well as in extending the existing body of knowledge on IT outsourcing governance.     

Illiquidity or credit deterioration: A study of liquidity in the US corporate bond market during financial crises

We investigate whether liquidity is an important price factor in the US corporate bond market. In particular, we focus on whether liquidity effects are more pronounced in periods of financial crises, especially for bonds with high credit risk, using a unique data set covering more than 20,000 bonds, between October 2004 and December 2008. We employ a wide range of liquidity measures and find that liquidity effects account for approximately 14% of the explained market-wide corporate yield spread changes. We conclude that the economic impact of the liquidity measures is significantly larger in periods of crisis, and for speculative grade bonds.     

Evolution of Strategic Levers in Insurance Claims Management: An Industry Survey

This article discusses competing strategic goals and success factors in nonlife insurers' claims management using new and ad hoc empirical data. We structure the study of the companies' aims along the three main conflicting goals: (1) the minimization of claims volume, (2) the optimization of internal claims processes, and (3) the maximization of customer satisfaction. We analyze the insurance industry perspective through a qualitative survey carried out in Germany and Switzerland. Findings on the current and expected importance of selected topics are derived. The results shall lead to managerial implications improving industry practice and serve as a starting point for further research. Our findings are relevant for academics and practitioners beyond the two markets surveyed in the study.     

Do mass layoffs affect voting behaviour? Evidence from the UK

How bad are mass layoffs politically? We study this question across both regional and individual-level datasets. Using a difference-in-difference framework with differential timing on constituency-level data for the UK, we find no evidence that mass layoff announcements negatively affect incumbents – either locally or nationally – in the General Elections 2010, 2015, 2017 and 2019. Using individual data on party preferences, we demonstrate that our results are not an artefact of the UK majority voting system and associated tactical voting. We also find no evidence that the null results can be explained by increased outmigration of affected individuals or changes of candidates by political parties. We find evidence that economic expectations are not strongly affected by mass layoffs, which, although a surprising finding by itself, might help to explain the absence of an effect on political outcomes.     

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.

COSTS OF HOUSING CRISES: INTERNATIONAL EVIDENCE

This paper analyses the costs of housing crises in terms of GDP growth and the economic conditions under which crises are particularly costly. Housing crises are often followed by recessions that are longer than other recessions. According to empirical estimates, a housing crisis reduces the GDP growth rate in the following year on average by two percentage points and has still a considerable negative impact in the second year. One important channel through which the effect of housing crises is passed on seems to be the banking sector. In addition, our results suggest that negative wealth effects possibly cause further reductions in GDP growth.     

The marketing firm: Retailer and consumer contingencies

Efficiency has emerged as an important consumer value and thus has increased the importance of the in-store search as one facet of consumer transaction costs. This paper contributes to the development of a marketing theory of the firm by analyzing the consumers' in-store efficiency ratios and the retailers' natural sources of resistance to offer efficiency to all of their customers. We propose new behavioral metrics for consumer transaction costs. Our data from the behavioral tracking of 497 complete shopping trips reveal more transaction costs for quick shopping trips than for regular shopping trips, which demonstrates friction between retail and consumer transaction costs for quick trips.     

Machine and labor flexibility in manufacturing networks

Many industrial companies today operate under strict employment legislation and work agreements. Since flexible capacity has been widely recognized as an important hedge against uncertain demand, there exist strong efforts to introduce more flexible workforce models. In this paper, we investigate the benefits of such labor flexibility and its interplay with machine flexibility from a network capacity investment perspective.We consider a firm that has to invest simultaneously in labor and machine capacity under uncertain demand and a given network configuration while anticipating the deployment of labor flexibility after demand has been realized. Instruments of labor flexibility range from temporary employment to personnel transfers between plants. The underlying decision problem is formulated as a two-stage stochastic program with recourse.Based on numerical studies and the analysis of a stylized model, we demonstrate the impact of labor flexibility on the optimal levels of machine and labor capacity. We compare the benefits obtained by personnel transfers with those of temporary workers and find that temporary employment always decreases the number of permanent workers, while personnel transfers may even allow for a larger workforce. Our results further indicate that personnel transfers are more effective in larger manufacturing networks although these benefits are decreasing when most plants in the network are capable of producing more than one product (machine flexibility). Finally, we present evidence for the efficiency of a combined usage of personnel transfers and temporary workers.
