On the economics of the longevity risk transfer market

We present a model of a longevity risk transfer market with different market players (primary insurers, reinsurers, and capital market investors) and investigate how market dynamics and the market players' roles evolve with progressing market saturation. We find that reinsurers' appetite for longevity risk is the key driver in the early stage of market development. Since diversification benefits with other businesses decrease with every transaction, the reinsurance market is intrinsically antimonopolistic. With the increasing saturation of the reinsurance sector as a whole, its competitiveness shrinks leading to rising expected risk-adjusted returns for capital market investors. We show that in a saturated market, reinsurers should assume the entire longevity risk from primary insurers, diversify it within their business mix, and subsequently pass on only specific (nondiversifiable) components of the longevity risk to the capital markets. Our findings provide valuable suggestions on how to make the best use of the market's limited risk absorption capacity.     

Wirtschaftswissenschaften: zu wenig Pluralität der Methoden und Forschungsrichtungen?

The authors discuss the merits of including pluralist methods, theories and paradigms into the traditionally mainstream. They also evaluate the progress made by German faculties in this regard. The pluralism debate is in itself plural. There are numerous international and Germany specific dimensions and associated critiques of mainstream economics. Different approaches to economic policy must be organised in a manner which guarantees theoretical and paradigmatic pluralism — on which economic policy proposals ought to be based. Another view focuses on the educational effect and states that the mental frames of economics students are subject to manipulation; the foundation of their thinking is narrowed and recontextualised in an emotionally and politically highly charged semantic environment.

Organizing Flexibility: The Flexible Firm in a New Century

Research on organizational flexibility should examine the linkages between numerical and functional flexibility. Unfortunately, studies of each type of flexibility generally neglect the other. Moreover, the most popular conception of the interplay between these two forms of flexibility — the core–periphery model — is incomplete in important ways. I discuss evidence and limitations of the core–periphery model of the flexible firm, and outline some promising attempts to conceptualize how organizations may combine functional and numerical flexibility. I focus mainly on the USA and the UK, though I also review evidence and issues involved in cross‐national differences in organizational flexibility.     

INVESTIGATING ALTERNATIVE APPROACHES TO HARMONISE MULTI-REGIONAL INPUT–OUTPUT DATA

Over recent years a small number of global multi-regional input–output (MRIO) databases were developed to describe the entire global economy at high sector detail. We investigate the differences that arise out of applying different construction procedures for two global MRIO databases: The EXIOBASE database, developed as part of the EU FP6 & 7 programs and the Eora database developed at the University of Sydney. The procedures used in EXIOBASE involve a high degree of interrogation and adjustment throughout the construction of the data set, whilst the Eora MRIO relies on single-step mathematical programming techniques and high-performance computing. We unravel the effect of the different approaches taken to develop the databases by undertaking a number of combinatorial experiments in which we exchange parts of the construction process between the EXIOBASE and Eora build pipelines. We conclude that Eora's highly automated data reconciliation approach produces MRIO databases that are of comparable quality to those constructed with EXIOBASE's multi-step approach. However, the reliability and robustness of the resulting MRIO database largely depend on the level of detail and reliability of the underlying raw data.     

Wage Effects of Labour Migration with International Capital Mobility

Wage effects of immigration are investigated in a setting with international capital mobility, which eliminates two‐thirds of the native wage effects of immigration. Without international capital mobility, overall gains from migration in the immigration region are only a small fraction of total losses to native workers, but with perfect international capital adjustment, overall gains are larger than total losses to native workers. Two alternative tax policies to eliminate the negative wage effects of immigration on low‐skilled native workers are evaluated.     

The Influence of Retail Management’s Use of Social Power on Corporate Ethical Values,Employee Commitment,and Performance

Recent cases in retailing reflect that ethics have a major impact on brands and performance, in turn, demonstrating that brand owners, employees, and consumers focus on ethical values. In this study, we analyze how various sources of social power affect corporate ethical values, retailer’s commitment to the retail organization, and ultimately sales and service quality. Multi-source data based on a sample of 225 retailers indicated a strong link between power, ethics, and commitment and that these affected output performance.
