The Impact

In this paper, we empirically examine the impact of performance feedback on the outcome of crowdsourcing contests. We develop a dynamic structural model to capture the economic processes that drive contest participants’ behavior and estimate the model using a detailed data set about real online logo design contests. Our rich model captures key features of the crowdsourcing context, including a large participant pool; entries by new participants throughout the contest; exploitation (revision of previous submissions) and exploration (radically novel submissions) behaviors by contest incumbents; and the participants’ strategic choice among these entry, exploration, and exploitation decisions in a dynamic game. Using counterfactual simulations, we compare the outcome of crowdsourcing contests under alternative feedback disclosure policies and award levels. Our simulation results suggest that, despite its prevalence on many platforms, the full feedback policy (providing feedback throughout the contest) may not be optimal. The late feedback policy (providing feedback only in the second half of the contest) leads to a better overall contest outcome.

The Impact

This study examined the association between generativity and psychological well-being for a subsample of 1882 mid- to late-life parents using the MIDUS data set. Guided by Erikson's theory of psychosocial development, we tested a structural model of psychological well-being that also included direct and indirect effects (via generativity) of remembered pre-adult relationships with parents and current parental experiences with offspring on well-being. Respondents who recalled positive, trusting relationships with parents in childhood reported more positive parental experiences with their adult offspring and better psychological well-being. Current parental experiences had both indirect and direct effects on well-being too, but generativity had the strongest direct effects. Thus, it appears that the achievement of generativity plays a substantial role in well-being in mid- and late life. Findings also reveal that the impact of generativity on well-being is stronger for females than males. Implications for intervention with older adults, such as promoting volunteer work, are discussed.

PurposeThis paper aims to examine the credit composition and income inequality reduction in Vietnam. In particular, the authors focus on the distinction between policy and commercial credits and investigate whether these two types of credit had adverse effects on income inequality. The authors also examine whether the impact of policy credit on income inequality is conditioned by the educational level and institutional quality.Design/methodology/approachThe authors use the primary data set, which contains a panel of 60 provinces collected from the General Statistics Office of Vietnam from 2002 to 2016. The authors employ the generalized method of moments to solve the endogenous problem.FindingsThe authors show that while commercial credit increases income inequality, policy credit contributes to reducing income inequality in Vietnam. In addition, we provide evidence that the institutional quality and educational level condition the impact of policy credit on income inequality. Based on the findings, the paper implies that it was not the size of the private credit but its composition that mattered in reducing income inequality, due to the asymmetric effects of different types of credit.Originality/valueThis is the first study that examines the links between the two components of credit and income inequality as well as constraints of the links. The authors argue that analyzing the separate effects of commercial and policy credits is more important for explaining the role of credit in income inequality than the size of total credit.

The Impact

The impact of collaboration on innovation performance has been investigated in many studies. This study provides a unique view on innovation performance by exploring the mediating role of social performance between collaboration and innovation performance. For this, a structural model was tested through an empirical investigation with partial least squares structural equation modelling (PLS-SEM) using a sample made up of 239 export manufacturing firms. The results of the empirical study show that social performance appears to be a necessary condition for innovation performance. Our findings confirm the great potential of addressing social concern increasingly drive innovation performance. The next decade is likely to be a period of rapidly expanding social performance practices in the manufacturing firms. The managers could foster sustainable innovation by collaborating customers and enhance their firm social performance.

Purpose Significant increase or decrease in research and development (R&D) expenditure may have an immense impact on market value. Based on the punctuated equilibrium theory, this paper aims to empirically analyze the impact of R&D volatilities on market value and the moderating effect of executive overconfidence. Design/methodology/approach The study uses the panel data set that covers 902 Shanghai and Shenzhen A-share manufacturing listed firms and multiple regression method to test the theoretical hypotheses. Findings The results show that both positive and negative R&D volatilities have a robust and significant positive impact on the market value. Further analysis shows that the executive overconfidence positively moderates the relationship between R&D volatilities and market value. Research limitations/implications In a rapidly changing and highly competitive environment, firms should recognize that the balance of innovation strategies will help to bring higher market value. Furthermore, firms could improve corporate governance to make the best of managerial characteristics, such as overconfidence, on the innovation decision-making process. Originality/value By pushing the static perspective to a dynamic perspective and empirically documenting the role of executive overconfidence, this study contributes to the literature on the relationship between R&D expenditure and market value, generating theoretical and practical insights for firms to improve innovation governance and innovation strategies to achieve better business performance.

Purpose – This study aims to examine the impact of news frames associated with traditional media and with Twitter discourse on social issues. Design/methodology/approach – Using semantic network analysis, it identifies the role of new alternative channels as well as discussing ways of understanding and consuming news content in the changing media environment. Additionally, it focuses on the dominant Twitter communicators who rank high in betweenness centrality. Findings – The results confirmed that traditional news media tend to superficially describe main events and media strikes without comment. They tended to consciously or unconsciously favor media corporations by engendering anxiety and conflict or by restraining reports on the rationales of the strike. Twitter discourse, on the contrary, positively represents the striker's arguments and frequently reveals support of the strike. Research limitations/implications – The data set of this study was specialized, not generalized. However, the findings extend literature relating to the role of journalism and alternative channel. For example, this study indicated that the change of media environment has reinforced partiality of news, including both traditional and alternative channels. Practical implications – The findings imply that the advent of new media does not purely represent a laymen's voice and rather tends to strengthen the partiality of media, including both traditional and new media, beyond selective exposure on content of the receiver. Originality/value – By clarifying the influence of alternative channels, this study suggests the counterpart of traditional journalism in the near future.

The Impact

Logit choice models have been used extensively to study promotion response. This article examines whether brand-switching elasticities derived from these models are overestimated as a result of rational consumer adjustment of purchase timing to coincide with promotion schedules and whether a dynamic structural model can address this bias. Using simulated data, the authors first show that if the structural model is correct, brand-switching elasticities are overestimated by stand-alone logit models. A nested logit model improves the estimates, but not completely. Second, the authors estimate the models on real data. The results indicate that the structural model fits better and produces sensible coefficient estimates. The authors then observe the same pattern in switching elasticities as they do in the simulation. Third, the authors predict sales assuming a 50% increase in promotion frequency. The reduced-form models predict much higher sales levels than does the dynamic structural model. The authors conclude that reduced-form model estimates of brand-switching elasticities can be overstated and that a dynamic structural model is best for addressing the problem. Reduced-form models that include incidence can partially, though not completely, address the issue. The authors discuss the implications for researchers and managers.

The Impact

This study investigates whether and how the impact of drivers of aspiration levels changes across the cases of consistent and inconsistent performance feedback within the context of a retailer. Analysis of internal corporate data shows that while past aspiration level and performance–aspiration gap positively influence the current aspiration level in the case of inconsistent feedback, performance feedback consistency changes only the impact of performance relative to peers. This study replicates past research in a different industry and country due to limited empirical evidence, introduces real-world complexity into aspiration theory, pinpoints performance–aspiration gap as the primary performance feedback, introduces a new sign for the impact of performance relative to peers, and reconciles its previously detected mixed impact. The findings suggest that organizational attention has an inward focus in the case of inconsistent feedback. The results also point out that leaders can trigger change through a performance outcome that lags behind the corresponding aspiration level rather than the performance of peers and eventually move their organizations toward high performance targets by starting with feasible rather than stretch goals.

Abstract This article investigates the role of mass media in times of conflict and state-sponsored mass violence against civilians. We use a unique village-level data set from the Rwandan genocide to estimate the impact of a popular radio station that encouraged violence against the Tutsi minority population. The results show that the broadcasts had a significant effect on participation in killings by both militia groups and ordinary civilians. An estimated 51,000 perpetrators, or approximately 10% of the overall violence, can be attributed to the station. The broadcasts increased militia violence not only directly by influencing behavior in villages with radio reception but also indirectly by increasing participation in neighboring villages. In fact, spillovers are estimated to have caused more militia violence than the direct effects. Thus, the article provides evidence that mass media can affect participation in violence directly due to exposure and indirectly due to social interactions.
