This study analyzes the impact of purpose-oriented leadership and leader cultural intelligence on engagement and burnout among expatriates undertaking long-term corporate assignments, grounded on social psychology frameworks on interpersonal bias.

A survey was conducted with corporate expatriates from 21 different nationalities, who work for large multinational companies and were on assignment in 23 distinct countries – including Brazil, China, Japan and the UK Partial Least Squares Structural Equation Modeling was used to evaluate the proposed hypotheses.

Results indicate that leader cultural intelligence is associated with lower burnout and higher engagement among expatriates, and that purpose-oriented leadership is associated with higher expatriate engagement but not with lower burnout.

This research contributes to the field by highlighting specific leader attributes that can foster successful expatriation: cultural intelligence and purpose-oriented leadership. The study adds to knowledge on leader–follower relationships amid national and cultural diversity by pointing to actionable leader qualities that can foster expatriate engagement and prevent his/her burnout.

This study investigates the influence of shared leadership on creativity and absorptive capacity in R&D teams. Based on theories of intragroup processes, it proposes that shared leadership positively affects such team outcomes up to a certain point, but at very high levels could cause loss of synergy and effectiveness, and therefore the relationship will follow an inverted U-shaped curve.

The study was conducted with 76 independent teams from the R&D unit of one of the largest energy companies in Brazil. Data were collected with two questionnaires answered by external team managers and team members. The study applied structural equation modeling to test the hypotheses.

Results indicate that there is a curvilinear relationship between shared leadership and external assessments of creativity and absorptive capacity in R&D teams. Although leadership shared among team members tends to favor creativity and realized absorptive capacity, at very high levels it yielded less than optimal outcomes. Team creativity had a direct positive effect on the teams' ability to explore and transform knowledge.

The study is the first empirical test of the influence of shared leadership on team creativity and absorptive capacity that proposes and confirms a quadratic effect. These results shed new light on the authors’ understanding of how intrateam leadership affects creative processes and absorptive capacity in the R&D context. These findings offer novel insights to inform practice as firms manage innovation performance.

The purpose of this paper is to present the results of a study on investor behavior in exchange-traded fund (ETF) markets. The standard feedback trading model of Sentana and Wadhwani (1992) is used in a sample of 18 ETFs contracts in Brazil, China, South Africa, Korea, Mexico and India, as well as three ETFs contracts in the US market.

The sample includes data on daily closing prices and net asset values (NAVs) for three ETFs from each of the emerging markets of Brazil, China, Mexico, Korea and India, as well as on three ETFs from the US market. The authors used the earliest start date available in the Thomson Reuters database pertaining to all of the ETFs, and all series ended on May 5, 2017, and applied the well-established Santana and Wadhwani (1992) seminal model to evaluate evidence of feedback trading in the sample.

The empirical analysis suggests that there is evidence of feedback trading in emerging markets such as Brazil, Korea, Mexico and India, while there is no such evidence for the US market. The results are consistent with the view that developed markets investors are prone to pursue fundamental-driven investment strategies, while emerging markets investors appear to have informational guided behavior.

Emerging markets still make up a very small part of the global ETF market, led by the USA. Nevertheless, it is extremely important that studies of this nature be gradually expanded as these markets grow, in order to verify how emerging markets compare to their developed counterparts in terms of the efficiency of information sharing and rationalization of its operations.

Emerging markets policy makers could benefit from these findings by stimulating new mechanisms that could minimize informational asymmetry and the persistence of so-called noise traders, a phenomenon observed recently in studies regarding ETF markets (Brown, Davies and Ringgenberg, 2018).

The behavior of investors was investigated by analyzing a sample of 18 ETFs from the emerging markets of Brazil, China, South Africa, Korea, India and Mexico, as well as three ETFs from the US market. Despite of being investigated separately both emerging (Charteris et al., 2014) and developed markets (Chau et al., 2011), the innovation consists in comparing those markets in a single study, pursuing to explain potential reasons for the differences observed between developed and emerging markets.
