Arbeiten 4.0 — Folgen der Digitalisierung für die Arbeitswelt

Digitalisation will not only lead to the disappearance of jobs, the creation of new jobs and changing skill requirements in many existing jobs. It also leads to fundamental challenges for existing qualification systems as well as labour law and labour relations. New digital technologies pervasively change the content and organisation of work. They may have an impact on the actual weekly working time hours and the adoption of self-managed working time systems. The consequences, however, may differ for each worker. Accordingly, economic and policy conclusions cannot be derived for the labour market as a whole. Workers‘qualifications need not only to be adapted to changing occupational tasks. Work intensification and increasing communication flows have to be addressed as well. Furthermore, adequate human resources policies can foster the proper use of new flexible work arrangements. Crowdworking as a specific form of flexible work, however, has to be primarily integrated in existing labour legislation. That is one opinion, another author considers the forecasts doomsday prophecies that call for political action or amending the regulative framework. And he suggests that the characteristics of the digital transformation of work may mainly be firm-specific. In a social-scientific perspective there is no deterministic relationship between technology and work but the development of work has to be regarded as a strategic and political design project.     

Energy Informatics

Due to the increasing importance of producing and consuming energy more sustainably, Energy Informatics (EI) has evolved into a thriving research area within the CS/IS community. The article attempts to characterize this young and dynamic field of research by describing current EI research topics and methods and provides an outlook of how the field might evolve in the future. It is shown that two general research questions have received the most attention so far and are likely to dominate the EI research agenda in the coming years: How to leverage information and communication technology (ICT) to (1) improve energy efficiency, and (2) to integrate decentralized renewable energy sources into the power grid. Selected EI streams are reviewed, highlighting how the respective research questions are broken down into specific research projects and how EI researchers have made contributions based on their individual academic background.     

Shady business: On the history of white-collar crime

Abstract

White-collar crime is a daily topic in the news but by no means a new phenomenon. The article invites readers to explore the historical dimensions of these very specific offences. It discusses how to define white-collar crime and how to analyse it. It names six characteristics of white-collar crime, namely the preponderance of upper and middle-class delinquents, the motivation of financial gain, non-violence, systemic character, the breach of trust, and diffuse victimisation. It also highlights additional aspects for a working definition which can be applied to various and even rapidly changing historical contexts. The history of white-collar crime draws attention to the intersection of business and the law, and to its interaction with innovation, moral discourse and public perception, as well as with the changing nature of state policies during the past two centuries. The article introduces the special issue and discusses methods and approaches suited to analysing ‘shady business’.

… Und sie bewegt sich doch! Ein blick in Geschichte und Gegenwart der Personenversicherungsmathematik

Contrary to non-life insurance mathematics, to mathematical risk theory and, in particular, to mathematical finance, life insurance mathematics is often viewed as static, impressed by long term regulation and administrative supervision of insurance markets in many countries, in short: as a scientifically not very attractive part of actuarial mathematics. With this paper, we want to point out that this is a prejudice. For this, the reader’s attention is drawn to the time when life insurance mathematics started to move, to the 17th century, in particular to the birth and prime of modern life insurance in the then absolutistic France and in the Netherlands. We try to indicate, which needs of the society gave rise to this development and which ?mathematical needs“ came up as a consequence. In the most important fields (mathematical finance, mathematical modelling of the biometric risk, actuarial modelling) we draw a line from there to modern developments.     

Near-efficient equilibria in contribution-based competitive grouping

We examine theoretically and experimentally how competitive contribution-based group formation affects incentives to free-ride. We introduce a new formal model of social production, called a “Group-based Meritocracy Mechanism” (GBM), which extends the single-group-level analysis of a Voluntary Contribution Mechanism (VCM) to multiple groups. In a GBM individuals are ranked according to their group contributions. Based on this ranking, participants are then partitioned into equal-sized groups. Members of each group share their collective output equally amongst themselves according to a VCM payoff function. The GBM has two pure-strategy Nash equilibria. One is non-contribution by all; this equilibrium thus coincides with the VCM's equilibrium. The second equilibrium is close to Pareto optimal. It is asymmetric and quite complex from the viewpoint of experimental subjects, yet subjects tacitly coordinate this equilibrium reliably and precisely. Extensions of the basic GBM model to incorporate various features of naturally occurring group formation are suggested in the conclusion.     

WHY FOREIGN OWNERSHIP MAY BE GOOD FOR YOU*

We develop a two‐country model with heterogeneous producers and rent‐sharing at the firm level. We identify two sources of a multinational wage premium: A composition effect because multinational firms are more productive, make higher profits, and pay higher wages, and a firm‐level wage effect, because a firm makes higher global profits and thus pays higher wages in its home market when becoming multinational. With two identical countries, the wage premium is fully explained by firm characteristics. Allowing for technology differences between countries, a residual wage premium exists in the technologically backward country but not in the advanced country.     

STOCK PRICE REACTIONS TO DIVIDEND AND EARNINGS ANNOUNCEMENTS: CONTEMPORANEOUS VERSUS NONCONTEMPORANEOUS ANNOUNCEMENTS

In this paper we examine stock price reactions to contemporaneous and noncontemporaneous dividend and earnings announcements. Overall, the stock price reaction to joint announcements is significantly greater than the reaction to just one signal. This implies that there is information content to two signals being given simultaneously, and that announcements are not perfect substitutes. Some evidence shows that the reaction to a joint announcement is approximately twice that to a noncontemporaneous announcement. On average, the stock price reaction to joint contradictory announcements is not significant. Finally, for joint announcements where only one of the two announcements is expected to affect the stock price significantly, the market reaction is determined by the nonzero signal.
