Maintenance and destrcution of R&D leadership

In the standard Schumpeterian-growth models only follower firms invest in R&D activities and larger economies grow faster. Since these results are counterfactual, this paper reveals that leader firms often support R&D activities and economic growth can be independent of the market size. In particular, the maintenance of R&D leadership increases with: (i) the technological-knowledge gap between leader and followers, since a firm-specific learning effect of accumulated technological knowledge from past R&D is considered, (ii) the leaders’ strategies that delay the next successful R&D supported by some follower firm, (iii) the market size, and (iv) the up-grade of each innovation.

Two-production-period in a duopoly with nonprofit and for-profit firms

We investigate endogenous roles in a competition between a nonprofit firm and a for-profit firm in a homogeneous goods market, by allowing two production periods. We find that the Cournot-type equilibrium and one Stackelberg-type equilibrium where the nonprofit firm becomes the follower exist; however, another tackelberg-type equilibrium where the nonprofit firm becomes the leader does not exist.

Privatization and government preference in a public Stackelberg leader duopoly

We analyse the relationship between the privatization of a public firm and government preferences for tax revenue in a Stackelberg duopoly with the public firm as the leader. We assume that the government payoff is given by a weighted sum of tax revenue and the sum of consumer and producer surplus. We get that if the government puts a sufficiently larger weight on tax revenue than on the sum of both surpluses, it will not privatize the public firm. In contrast, if the government puts a moderately larger weight on tax revenue than on the sum of both surpluses, it will privatize the public firm.

Environmental taxes in a public Stackelberg leader duopoly

We study whether privatization of a public firm improves (or deteriorates) the environment in a mixed Stackelberg duopoly with the public firm as the leader. We assume that each firm can prevent pollution by undertaking abatement measures. We get that, since in the mixed market the industry output is higher than in the private market, the abatement levels are also higher in the mixed market, and, thus, environmental tax rate in the mixed duopoly is higher than that in the privatized duopoly. Furthermore, the environment is more damaged in the mixed than in the private market. The overall effect on the social welfare is that it will becomes higher in the private than in the mixed market.

Asymmetric dynamic price competition with uncertainty

We consider a dynamic setting-price duopoly model in which a dominant (leader) firm moves first and a subordinate (follower) firm moves second. We suppose that each firm has two different technologies, and uses one of them according to a certain probability distribution. The use of either one or the other technology affects the unitary production cost. We analyse the effect of the production costs uncertainty on the profits of the firms, for different values of the intercept demand parameters.

The impact of talent management practices on employee retention: The moderator effect of leader-member exchange and role modeling

Organizations are undergoing serious difficulties to retain talent. Authors argue that Talent Management (TM) practices create beneficial outcomes for individuals and organizations. However, there is no research on the leaders’ role in the functioning of these practices. This study examines how LMX and role modeling influence the impact that TM practices have on employees’ trust in their organizations and retention. The analysis of two questionnaires (Nt1=175; Nt2=107) indicated that TM only reduced turnover intentions, via an increase in trust in the organization, when role modeling was high and not when it was low. Therefore, we can say that leaders are crucial in the TM context, and in sustaining a competitive advantage for organizations.

A qualitative approach to define the prototype of a Portuguese expatriate leader in Angola

This qualitative research analyzes the individual life experiences of Portuguese expatriate leaders who left their home country to work at organizations in Angola, a place that offers better job opportunities. Through interviews with those professionals and their followers, a prototype of a Portuguese expatriate leader in Angola has been developed. Even though Angola is a former Portuguese colony, it was at war for many years and so the economic situation and culture of the country are distant from what Portuguese workers are used too, which requires them to adapt and be open-minded to change.

Characterization of a Trypanosoma cruzi genomic fragment complementary to several species-specific mRNAs but different from the spliced leader sequence

We have isolated a clone of Trypanosoma cruzi genimic DNA, lambda 3b2-5, which contains sequences that are reiterated in the genome. Northtern blot analysis showed that clone 3b2-5 hybridizes to 1,200-5,000 bases different mRNA species. The number of mRNAs species hybridized to clone 3b2-5 exceeds its coding capacity showing that this clone carries sequences that are common to several mRNAs species and conserved in the poly A(+) RNA. These sequences are not homologous to the T. cruzi spliced leader sequence, since clone 3b2-5 hybridize to a synthetic 20 nucleotice complementary to the spliced leader sequence. Clone 3b2-5 does not hybridize to DNA and RNA from several genera of Trypanosomatidae and other Trypanosoma species indicating that it carries T. cruzi species-specific sequences.

Three essays on leadership

ABSTRACT Samuel Bendahan, John Antonakis, Christian Zehnder, and François Pralong The relationship between power and immoral decisions has been discussed extensively by scientists and philosophers alike. Although the exercise of power is ubiquitous in social hierarchies, direct evidence on the impact of power on decision making is scarce. We use laboratory experiments to study whether more power leads to corruption. We manipulate power in the context of leader decision-making authority involving monetary stakes. Prior to the experiment, we also gathered extensive data on psychological and endocrinological individual differences. We find that an increase of power caused leaders to be more likely to engage in destructive, selfish behaviour, although the same subjects did not behave in this manner before their level of power was increased. We also show how individual differences affect the initial level of destructive behaviour and the corruption process. WHAT'S RIGHT FOR THE LEFT MAY NOT BE RIGHT FOR THE RIGHT: VALUE CONGRUENCE AND CHARISMA IN POLITICAL LEADERSHIP Samuel Bendahan ABSTRACT Value congruence between leaders and followers is important not only for follower commitment but also as part of the attributions followers make of leaders. I theorized that transformational leadership, which often is referred to as being value driven and having strong moral foundations, has differential effects depending on the values of the follower and whether these values are congruent with what the leader espouses. I designed an experiment to analyze how the political values of followers and leaders can influence followers' attributions regarding leaders. Within the context of political leadership, I found that transformational leaders were seen as more prototypical. Value congruence predicted prototypicality, which was strongly related to follower intentions to vote for the leader. Furthermore, followers with left-wing political values were more influenced by prototypical leaders than were followers with right-wing political values, presumably because of moral overtones of both left-wing ideology and transformational leadership. JUDGING LEADERSHIP POTENTIAL IN AN INTERVIEW: MODERATING EFFECT OF INTERVIEWER INTELLIGENCE ON INTERVIEWER COGNITIVE BUSYNESS, CANDIDATE PERFORMANCE-CUES EFFECTS, AND CANDIDATE ETHNICITY Samuel Bendahan, Philippe Jacquart, and John Antonakis ABSTRACT A large body of literature suggests that interviewers do not accurately rate candidates when using unstructured interviews and evaluation procedures that affect pre-interview expectations; however, the process by which these biases are produced is not well understood. We theorized several reasons for the sub-par performance of the unstructured interview. These factors, which we manipulated in the context of a videotaped interview of a candidate applying for a leadership position, include evaluator cognitive load, pre-interview performance cues regarding the candidate, and the ethnicity of the candidate. We also controlled for the intelligence of the evaluator. We found a significant four-way interaction between the manipulated factors and evaluators' cognitive abilities. The effects of the manipulated factors were all significantly less for evaluators who were high on general intelligence.
