Subject pool effects in price competition games: students versus professionals

Questioning the external validity of experiments that rely on student participants is an evergreen theme in experimental economics. Yet, there is ambiguous evidence of potential subject-pool bias. We add to the subject-pool debate by enlarging the set of experiments for which subject-pool differences have been studied. In a duopolistic Bertrand market setup designed to test for collusive behaviour, we test two treatments. The first is a baseline treatment, where participants cannot communicate with each other, while the second is a communication treatment in which participants are allowed to communicate. Each treatment is first conducted with students and then replicated with professionals. Our results show that student subjects and professionals differ significantly. However, these differences manifest themselves in quantitative rather than qualitative terms. Professionals do collude more, but their behavioural difference between treatments is similar. Students are thus a valid surrogate, if the research question is qualitative, but results generated by student samples should be handled with caution, if quantitative differences matter.     

The real impact of a one-off fiscal restriction: empirical evidence of a flypaper effect in Flemish municipalities

This paper analyses the effects of a one-off fiscal restriction on Flemish local government spending. The authors provide evidence of a ‘flypaper effect’: fiscal restriction stimulated the sensitivity of local spending to grants. This means that higher-level governments (regional/national/supranational) need to take a flypaper effect into account when considering one-off fiscal restrictions on lower-level governments.     

The global threat of deflation calls for swift interest rate cuts in Europe

Conclusions Given the serious crisis in Asia and evidence of its spreading to other developing and transition countries, the attempt by German economic policymakers to achieve faster economic growth and higher employment almost exclusively by means of successes on export markets appears likely to fail sooner than had been expected by the DIW⁵. The significance of domestic demand has been systematically underestimated in recent years. With the help of extremely low pay settlements, the D-Mark was devalued in real terms; this promoted exports, but at the same time led to growth losses in private consumption and investment that more than offset the gains in exports. On top of this German fiscal policy—as documented in the following report in this issue—has weakened domestic demand and investment activity. This strategy might have worked if a symmetrically oriented monetary policy had reacted to the deflationary trend inherent in pay settlements and the fiscal-policy stance by swiftly and significantly reducing interest rates. This did not happen. It was therefore inevitable that the crisis in sales markets made its full effects felt on economic growth. More seriously still, if cost deflation in Germany is not brought to an end in the coming year by a return to productivity-oriented wage settlements, it will pose a major threat to the European Monetary Union.⁶ If Germany pursues a beggar-thyneighbour policy in a Europe without exchange rates, this can only result in deflation and a downward economic spiral.⁷     

Front End Transfers of Digital Innovations in a Hybrid Agile-Stage-Gate Setting

Digital innovations often follow a more fluid innovation process and, therefore, require different ways of managing the front end of innovation. Agile as alternative to established front end management practices is often suggested, potentially combined with Stage-Gate, in what is called a hybrid Agile-Stage-Gate model, to reap the benefits from both. Implementing the hybrid model in the front end is however not sufficient for firms with separate Research and Development departments to succeed. In such organizations digital innovations still need to be transferred from Research, where the front end work on digital innovations takes place, to the Development department, where formal development actually starts. Yet, such front end transfers have been described as inefficient and ineffective. Realizing digital innovation front end transfers is likely even more challenging because of their fluid definition. In the absence of extant theory on front end transfers in such a setting, this research uses a case study approach to analyze the front end transfer experiences of the Research department of a firm in the lighting industry that is undergoing a transformation from traditional to digital lighting. The in-depth analysis of triangulated data on eight front end projects shows that Research struggles to transfer digital innovations to Development, because transfer practices in terms of management, scope, and synchronization, turn out to be inherently challenging in a hybrid Agile-Stage-Gate setting. Specifically, the results reveal that each transfer practice plays an intricate role in either facilitating (i.e., transfer management) or inhibiting (i.e., transfer scope and synchronization) front end transfers of digital innovations. The discovery of these opposing forces has important implications for novel theorizing on the use of Agile in the front end of digital innovation, transfer practices from Research to Development in a hybrid setting, as well as for theorizing about digital innovation management.     

Identity and entrepreneurship: do school peers shape entrepreneurial intentions?

We incorporate the concept of social identity into entrepreneurship and analyze the determinants of having entrepreneurial intentions. We argue that an entrepreneurial identity results from an individual’s socialization. This could be parental influence but, as argued in this paper, also peer influence. Based on Programme for International Student Assessment (PISA) 2006 data in which students report their entrepreneurial intentions at the age of 15, we find that having an entrepreneurial peer group has a positive effect on an individual’s entrepreneurial intentions. We find that the strength of the peer effect in a country is moderated by prevailing values, namely individualism.     

Beyond nudges: Tools of a choice architecture

The way a choice is presented influences what a decision-maker chooses. This paper outlines the tools available to choice architects, that is anyone who present people with choices. We divide these tools into two categories: those used in structuring the choice task and those used in describing the choice options. Tools for structuring the choice task address the idea of what to present to decision-makers, and tools for describing the choice options address the idea of how to present it. We discuss implementation issues in using choice architecture tools, including individual differences and errors in evaluation of choice outcomes. Finally, this paper presents a few applications that illustrate the positive effect choice architecture can have on real-world decisions.

ECB: Relaxation of monetary policy called for

Conclusions Neither money supply trends nor other relevant indicators suggest that the target of price stability is under threat in the foreseeable future. On the other hand, it is questionable whether output and employment will soon experience a strong and self-sustaining upturn. In such a situation cuts in central bank rates are called for as a support measure to underpin economic growth.
