On the Effects of Redistribution on Growth and Entrepreneurial Risk-taking

This paper investigates the effects of redistributive taxation on occupational choice and growth. We discuss a two-sector economy in the spirit of Romer (1990). Agents engage in one of two alternative occupations: either self-employment in an intermediate goods sector characterized by monopolistic competition, or employment as an ordinary worker in this sector. Entrepreneurial profits are stochastic. The occupational choice under risk endogenizes the number of firms in the intermediate goods industry. While the presence of entrepreneurial risk results in a suboptimally low number of firms and depresses growth, nonlinear tax schemes can sometimes compensate negative effects by ex post providing social insurance.     

Analysing disruptive potential: the case of wireless local area network and mobile communications network companies

In this article, we analyse the prediction that wireless local area network (W-LAN) technologies will be disruptive for incumbent mobile communications network operators. For this purpose, we develop a methodology of guided interviews to assess technologies for their disruptive characteristics based on theory of disruptive technology developed by Christensen (1997) and recent extensions. The application of our comprehensive step-by-step method improves the precision of the disruptive technology concept and its usability for practitioners to make ex ante distinctions between disruptive technologies and other phenomena caused by emerging technologies. Our method predicts that contrary to common assumptions, W-LAN is not likely to represent a disruptive technology for the established mobile communications network firms in terms of Christensen's concept. This research was conducted in close collaboration with Vodafone Pilotentwicklung, an R&D and technology monitoring unit of the Vodafone Group. Vodafone provided part of the empirical data through expert interviews and market reports.     

Technologically Reflective Individuals as Enablers of Social Innovation*

This paper identifies technologically reflective individuals and demonstrates their ability to develop innovations that benefit society. Technological reflectiveness (TR) is the tendency to think about the societal impact of an innovation, and those who display this capability in public are individuals who participate in online idea competitions focused on technical solutions for social problems (such as General Electric's eco‐challenge, the James Dyson Award, and the BOSCH Technology Horizon Award). However, technologically reflective individuals also reflect in private settings (e.g., when reading news updates), thus requiring a scale to identify them. This paper describes the systematic development of an easy‐to‐administer multi‐item scale to measure an individual's level of TR. Applying the TR scale in an empirical study on a health monitoring system confirmed that individuals' degree of TR relates positively to their ability to generate (1) more new product features and uses, (2) features with higher levels of societal impact, and (3) features that are more elaborated. This scale allows firms seeking to implement co‐creation in their new product development (NPD) process and sustainable solutions to identify such individuals. Thus, this paper indicates that companies wishing to introduce new technological products with a positive societal impact may profit from involving technologically reflective individuals in the NPD process.     

The effect of internal control and risk management regulation on earnings quality: Evidence from Germany

We investigate the impact of mandatory internal control and risk management (ICRM) reform on earnings-based attributes of accounting quality in Germany. Although prior studies examine changes in accounting quality under SOX Sections 302 and 404, there is scant evidence of the accounting quality effects of ICRM reform in foreign jurisdictions. Such evidence is warranted given the ongoing global policy debate of ICRM reform in the post-SOX era. We extend existing research by examining changes in earnings quality following the 1998 German legislation on control and transparency (KTG). The KTG regime provides a unique setting in which the regulatory scope extends beyond internal control over financial reporting (ICFR) to include broad business and enterprise risk control. Using both a differences and difference-in-differences research design, we find that German firms experience an increase in timely loss recognition and a decrease in earnings smoothing after KTG. We also find some evidence of a decrease in loss avoidance behavior. Additional analyses show that the sensitivity of capital investment efficiency to earnings quality increases in the German market after KTG, suggesting that earnings quality effects of mandatory ICRM reform has positive consequences for capital resource allocation. Together, our results are consistent with the achievement of one of the intended outcomes of ICRM regulation—increased accounting quality through effective ICRM systems.

«Kluge» Köpfe — «dumme» Körper?

The aim of the present study was to investigate, under realistic conditions, the empirically well proved phenomenon of higher facial prominence in newspaper photos of men compared to those of women («face-ism») and its reported effects on impression formation in beholders. At first, the mean face-ism indices of photos depicting males and females from four print media were calculated. In a second step real photos of male and female persons from these four print media were selected, corresponding exactly to the characteristic modal face-ism indices of their origin papers. These photos were rated by male and female reviewers concerning the attributes intelligence, ambition, attractiveness, and emotion. The judgements showed significant positive attributions of intelligence for all photos of high facial prominence. In addition, they showed higher attributions of intelligence and ambition for photos of men, higher attributions of attraction and emotion for photos of women, and furthermore some significant interactions concerning gender and age of reviewers. These findings are discussed with regard to cultural embeddings of non-conscious gender stereotypes.
